  • How do I remedy "Error: Cannot find module 'child-process-close'"?

    - by Tyler Sloan
    I was going about business as usual and about to checkout generator-angular-fullstack. I got no red errors but a message a the end saying Error: Cannot find module 'child-process-close'. I tried many a-thing–uninstalling node, reinstalling, manually getting rid of files and directories in local and/or global paths and tried to make sure Homebrew was the one who installed everything and somehow I've made things worse. (Also, I initially saw errors regarding karma. Everything looked right but it doesn't seem I did any good by throwing commands at it.) I am at a loss. All the stackoverflow questions have been clicked and I'm afraid I've probably tried too many of the suggestions. I cannot install any Yeoman generator. I cannot install anything with npm. When inside the project directory when I run npm install it throws the error. I really have no clue. Is there a way I can basically start over all together? A simple uninstall and install isn't cutting it. Something in the system needs to change but I don't know what. Any ideas?

  • ng-grid checkbox with filtering

    - by WilliamLou
    If I have a huge table with ng-grid, and I enabled a checkbox to select all. Is there a way for me to combine this selectAll feature with the filtering box. I mean when I filter out the rows, I want to click the checkbox so that the rows filtered will be all selected; once I clean out filter, those selectedRows are still left so that I can add more rows into it with other filters. I created a Plunker code template here. copy code here as well: // main.js var app = angular.module('myApp', ['ngGrid']); app.controller('MyCtrl', function($scope) { $scope.mySelections = []; $scope.myData = [{name: "Moroni", age: 50}, {name: "Tiancum", age: 43}, {name: "Jacob", age: 27}, {name: "Nephi", age: 29}, {name: "Enos", age: 34}, {name: "Moroni", age: 50}, {name: "Tiancum", age: 43}, {name: "Jacob", age: 27}, {name: "Nephi", age: 29}, {name: "Enos", age: 34}, {name: "Moroni", age: 50}, {name: "Tiancum", age: 43}, {name: "Jacob", age: 27}, {name: "Nephi", age: 29}, {name: "Enos", age: 34}, {name: "Moroni", age: 50}, {name: "Tiancum", age: 43}, {name: "Jacob", age: 27}, {name: "Nephi", age: 29}, {name: "Enos", age: 34},]; $scope.filterOptions = { filterText: '' }; $scope.gridOptions = { data: 'myData', checkboxHeaderTemplate: '<input class="ngSelectionHeader" type="checkbox" ng-model="allSelected" ng-change="toggleSelectAll(allSelected)"/>', showSelectionCheckbox: true, selectWithCheckboxOnly: false, selectedItems: $scope.mySelections, multiSelect: true, filterOptions: $scope.filterOptions }; });

  • Paddle Movement using Box2D

    - by Anubhav Sharma
    Hello everybody, I'm making a game like Arkanoid and to move the ship with mouse, I'm using the following code : var mousex:int = costume.stage.mouseX; if (mousex < paddleWidth/2) mousex = paddleWidth/2; else if (mousex > PhysiVals.STAGE_WIDTH - paddleWidth/2) mousex = PhysiVals.STAGE_WIDTH - paddleWidth / 2; var idealLocation:Point = new Point(mousex, ypos); var directionToTravel:b2Vec2 = new b2Vec2((idealLocation.x -> costume.x) * PhysiVals.paddleSpeed, idealLocation.y-costume.y); directionToTravel.Multiply(1 / PhysiVals.RATIO); directionToTravel.Multiply(30); body.SetLinearVelocity(directionToTravel); Everything's going fine there! The paddle is moving the way it should! The problem is I want a little inclination towards the direction its moving and when it stops moving the angle of inclination should become zero. I tried playing with the angular velocity but I have no real idea how to do this! So Please help!

  • Pass ng-model and place-holder value into directive

    - by Zen
    I have a segment of code needs to be reuse a lot, there for I want to just create a directive for it. <div class="btn-group"> <div class="input-group"> <div class="has-feedback"> <input type="text" class="form-control" placeholder="BLAH BLAH" ng-model="model"> <span class="times form-control-feedback" ng-click="model=''" ng-show="model.length > 0"></span> </div> </div> </div> I want to use this code as template in directive. Create a directive used as follow: <div search-Field ng-model="model" placeholder="STRING"></div> to replace to old html, ng-model and placeholder will be as variables. angular.module('searchField', []) .directive('searchField', [function () { return { scope: { placeholder: '@', ngModel: '=' }, templateUrl: 'Partials/_SearchInputGroup.html' } }]); Is it the way of doing it?

  • Keeping sync in multiplayer RTS game that uses floating point arithmetic

    - by Calmarius
    I'm writing a 2D space RTS game in C#. Single player works. Now I want to add some multiplayer functionality. I googled for it and it seems there is only one way to have thousands of units continuously moving without a powerful net connection: send only the commands through the network while running the same simulation at every player. And now there is a problem the entire engine uses doubles everywhere. And floating point calculations are depends heavily on compiler optimalizations and cpu architecture so it is very hard to keep things syncronized. And it is not grid based at all, and have a simple phisics engine to move the space-ships (space ships have impulse and angular-momentum...). So recoding the entire stuff to use fixed point would be quite cumbersome (but probably the only solution). So I have 2 options so far: Say bye to the current code and restart from scratch using integers Make the game LAN only where there is enough bandwidth to have 8 players with thousands of units and sending the positions and orientation etc in (almost) every frame... So I looking for better opinions, (or even tips on migrating the code to fixed-point without messing everything up...)

  • Plotting an Arc in Discrete Steps

    - by phobos51594
    Good afternoon, Background My question relates to the plotting of an arbitrary arc in space using discrete steps. It is unique, however, in that I am not drawing to a canvas in the typical sense. The firmware I am designing is for a gcode interpreter for a CNC mill that will translate commands into stepper motor movements. Now, I have already found a similar question on this very site, but the methodology suggested (Bresenham's Algorithm) appears to be incompatable for moving an object in space, as it only relies on the calculation of one octant of a circle which is then mirrored about the remaining axes of symmetry. Furthermore, the prescribed method of calculation an arc between two arbitrary angles relies on trigonometry (I am implementing on a microcontroller and would like to avoid costly trig functions, if possible) and simply not taking the steps that are out of the range. Finally, the algorithm only is designed to work in one rotational direction (e.g. counterclockwise). Question So, on to the actual question: Does anyone know of a general-purpose algorithm that can be used to "draw" an arbitrary arc in discrete steps while still giving respect to angular direction (CW / CCW)? The final implementation will be done in C, but the language for the purpose of the question is irrelevant. Thank you in advance. References S.O post on drawing a simple circle using Bresenham's Algorithm: "Drawing" an arc in discrete x-y steps Wiki page describing Bresenham's Algorithm for a circle http://en.wikipedia.org/wiki/Midpoint_circle_algorithm Gcode instructions to be implemented (see.

  • Debugging Post Request with Chrome Dev Tools

    - by benek
    I am trying to use Chrome Dev for debugging the following Angular post request : $http.post("http://picjboss.puma.lan:8880/fluxpousse/api/flow/createOrUpdateHeader", flowHeader) After running the statement with right-click / evaluate, I can see the post in the network panel with a pending state. How can I get the result or "commit" the request and leave easily this "pending" state from the dev console ? I am not yet very familiar with JS callbacks, some code is expected. Thanks.

  • How to use MySQL geospatial extensions with spherical geometries

    - by Joshua
    Hi Everyone, I would like to store thousands of latitude/longitude points in a MySQL db. I was successful at setting up the tables and adding the data using the geospatial extensions where the column 'coord' is a Point(lat, lng). Problem: I want to quickly find the 'N' closest entries to latitude 'X' degrees and longitude 'Y' degrees. Since the Distance() function has not yet been implemented, I used GLength() function to calculate the distance between (X,Y) and each of the entries, sorting by ascending distance, and limiting to 'N' results. The problem is that this is not calculating shortest distance with spherical geometry. Which means if Y = 179.9 degrees, the list of closest entries will only include longitudes of starting at 179.9 and decreasing even though closer entries exist with longitudes increasing from -179.9. How does one typically handle the discontinuity in longitude when working with spherical geometries in databases? There has to be an easy solution to this, but I must just be searching for the wrong thing because I have not found anything helpful. Should I just forget the GLength() function and create my own function for calculating angular separation? If I do this, will it still be fast and take advantage of the geospatial extensions? Thanks! josh UPDATE: This is exactly what I am describing above. However, it is only for SQL Server. Apparently SQL Server has a Geometry and Geography datatypes. The geography does exactly what I need. Is there something similar in MySQL?

  • Asynchronously get user data in facebook tab?

    - by Kristoffer Nolgren
    Using the php sdk, I check if a user inside a tab likes the corresponding page. If i put the following code inside index.php and use that page as my page-tab-url, <?php require_once("facebook/facebook.php"); // Create our application instance // (replace this with your appId and secret). $facebook = new Facebook(array( 'appId' => '1399475990283166', 'secret' => 'mysercret', 'cookie' => true )); $signed_request = $facebook->getSignedRequest(); echo $signed_request['page']['liked']; ?> it outputs '1'. I would like to achieve this asynchronously instead, so I put the php in a separate file and try to access it using ajax instead $http.post('/facebook/likes.php'). success(function(data){ console.log(data); }).error(function(data){ console.log(data); } ); This sample is using angular, but what javascript library i'm using probably doesn't matter. When I access the info with javascript Facebook doesn't seem to get the info that I liked the page. Adding a print_r($facebook); on the page I'm retreiving the same values as if i'm not in a facebook-tab: ( [sharedSessionID:protected] => [appId:protected] => 1399475990283166 [appSecret:protected] => 679fb0ab947c2b98e818f9240bc793da [user:protected] => [signedRequest:protected] => [state:protected] => [accessToken:protected] => [fileUploadSupport:protected] => [trustForwarded:protected] => ) Can I access theese values asynchronosly somehow?

  • Protecting routes with authentication in an AngularJS app

    - by Chris White
    Some of my AngularJS routes are to pages which require the user to be authenticated with my API. In those cases, I'd like the user to be redirected to the login page so they can authenticate. For example, if a guest accesses /account/settings, they should be redirected to the login form. From brainstorming I came up with listening for the $locationChangeStart event and if it's a location which requires authentication then redirect the user to the login form. I can do that simple enough in my applications run() event: .run(['$rootScope', function($rootScope) { $rootScope.$on('$locationChangeStart', function(event) { // Decide if this location required an authenticated user and redirect appropriately }); }]); The next step is keeping a list of all my applications routes that require authentication, so I tried adding them as parameters to my $routeProvider: $routeProvider.when('/account/settings', {templateUrl: '/partials/account/settings.html', controller: 'AccountSettingCtrl', requiresAuthentication: true}); But I don't see any way to get the requiresAuthentication key from within the $locationChangeStart event. Am I overthinking this? I tried to find a way for Angular to do this natively but couldn't find anything.

  • What happens with $q.all() when some calls work and others fail?

    - by Alan
    What happens with $q.all() when some calls work and others fail? I have the following code: var entityIdColumn = $scope.entityType.toLowerCase() + 'Id'; var requests = $scope.grid.data .filter(function (rowData, i) { return !angular.equals(rowData, $scope.grid.backup[i]); }) .map(function (rowData, i) { var entityId = rowData[entityIdColumn]; return $http.put('/api/' + $scope.entityType + '/' + entityId, rowData); }); $q.all(requests).then(function (allResponses) { //if all the requests succeeded, this will be called, and $q.all will get an //array of all their responses. console.log(allResponses[0].data); }, function (error) { //This will be called if $q.all finds any of the requests erroring. var abc = error; var def = 99; }); When all of the $http calls work then the allResponses array is filled with data. When one fails the it's my understanding that the second function will be called and the error variable given details. However can someone help explain to me what happens if some of the responses work and others fail?

  • Why is 50.22.53.71 hitting my localhost node.js in an attempt to find a php setup

    - by laggingreflex
    I just created a new app using angular-fullstack yeoman generator, edited it a bit to my liking, and ran it with grunt on my localhost, and immediately upon starting up I get this flood of requests to paths that I haven't even defined. Is this a hacking attempt? And if so, how does the hacker (human or bot) immediately know where my server is and when it came online? Note that I haven't made anything online, it's just a localhost setup and I'm merely connected to the internet. (Although my router does allow 80 port incoming.)

  • HTML5 and Visual Studio 2010

    - by Harish Ranganathan
    All of us work with Visual Studio (or the free Visual Web Developer Express Edition) for developing web applications targeting ASP.NET / ASP.NET MVC or Silverlight etc.,  Over the years, Visual Studio has grown to a great extent.  From being a simple limited functionality tool in VS.NET 2002 to the multi-faceted, MEF driven Visual Studio 2010, it has come a long way.  And as much as Visual Studio supports rapid web development by generating HTML mark up, it also added intellisense for some of the HTML specifications that one has otherwise monotonously type every time.  Ex.- In Visual Studio 2010, one can just type the angular bracket “<” and then the first keyword “h” or “x” for html or xhtml respectively and then press tab twice and it would render the entire markup required for XHTML or HTML 1.0/1.1 strict/transitional and the fully qualified W3C URL. The same holds good for specifying HTML type declaration.  Now, the difference between HTML and XHTML has been discussed in detail already, though, if you are interested to know, you can read it from http://www.w3schools.com/xhtml/xhtml_html.asp But, the industry trend or the buzz around is HTML5.  With browsers like IE9 Beta, Google Chrome, Firefox 4 etc., supporting HTML5 standards big time, everyone wants to start developing HTML5 based websites. VS developers (like me) often get the question around when would VS start supporting HTML5.  VS 2010 was released last year and HTML5 is still specifications under development.  Clearly, with the timelines we started developing Visual Studio (way back in 2008), HTML5 specs were almost non-existent.  Even today, the HTML5 body recommends not to fully depend on the entire mark up set as they are still under development specs and might change in the future. However, with Visual Studio 2010 SP1 beta, there is quite a bit of support for HTML5 based web development.  In fact, one of my colleagues pointed out that SP1 beta’s major enhancement is its ability to support HTML5 tags and even add server mode to them. Lets look at the existing validation schema available in Visual Studio (Tools – Options – Validation) This is before installing Visual Studio 2010 SP1 Beta.  Clearly, the validation options are restricted to HTML 4.01 and XHTML 1.1 transitional and below. Also, lets consider using some of the new HTML5 input type elements.  (I found out this, just today from my friend, also an, ASP.NET team member) <input type=”email”> is one of the new input type elements according to the HTML5 specification.  Now, this works well if you type it as is  in Visual Studio and the page renders without any issue (since the default behaviour is, if there is an “undefined” type specified to input tag, it would fall back on the default mode, which is text. The moment you add <input type=”email” runat=”server” >, you get an error Naturally you don’t get intellisense support as well for these new tags.  Once you install Visual Studio 2010 Service Pack 1 Beta from here (it takes a while so you need to be patient for the installation to complete), you will start getting additional Validation templates for HTML5, as below:- Once you set this, you can start using HTML5 elements in your web page without getting errors/warnings.  Look at the screen shot below, for the new “video” tag which is showing up in intellisense (video is a part of the new HTML5 specifications)     note that, you still need to hook up the <!DOCTYPE html /> on the top manually as it doesn’t change automatically  (from the default XHTML 1.0 strict) when you create a new page. Also, the new input type tags in HTML5 are also supported One, can also use the <asp:TextBox type=”email” which would in turn generate the <input type=”email”> markup when the page is rendered.  In fact, as of SP1 beta, this is the only way to put the new input type tags with the runat=”server” attribute (otherwise you will get the parser error mentioned above.  This issue would be fixed by the final release of SP1 beta) Going further, there may be more support for having server tags for some of the common HTML5 elements, but this is work in progress currently. So, other than not having runat=”server” support for the new HTML5  input tags, you can pretty much build and target HTML5 websites with Visual Studio 2010 SP1 Beta, today.  For those who are running Visual Studio 2008, you also have the “HTML5 intellisense for Visual Studio 2010 and 2008” available for download, from http://visualstudiogallery.msdn.microsoft.com/d771cbc8-d60a-40b0-a1d8-f19fc393127d/ Note that, if you are running Visual Studio 2010, the recommended approach is to install the SP1 beta which would be the way forward for HTML5 support in Visual Studio. Of course, you need to test these on a browser supporting HTML5 such as IE9 Beta or Chrome or FireFox 4.  You can download IE9 Beta from here You can also follow the Visual Web Developer Team Blog for more updates on the stuff they are building. Cheers !!!

  • jQuery Ajax (beforeSend and complete) working properly on FireFox but not on IE8 and Chrome

    - by Farhan Zia
    I am using jQuery ajax version 1.4.1 in my MVC application (though the issue I am discussing was same with the old jQuery version 3.2.1) as well, to check during customer registration if the username is already registered. As the user clicks on the "Check Availibility" button, I am showing a busy image in place of the check button (actually hiding the check button and showing the image) while checking the availibility on the server and then displaying a message. It is a Sync call (async: false) and I used beforeSend: and complete: to show and hide the busy image and the check button. This thing is working well on Firefox but in IE 8 and Chrome, neither the busy image appear nor the check button hides rather the check button remained pressed as the whole thing has hanged. The available and not available messages appear correctly though. Below is the code: HTML in a User Control (ascx): (i have replaced the angular braces with square below) [div id="available"]This Username is Available [div id="not_available"]This Username is not available [input id="txtUsername" name="txtUsername" type="text" size="50" /]  [button id="check" name="check" type="button"]Check Availability[/button] [img id="busy" src="/Content/Images/busy.gif" /] On the top of this user control, I am linking an external javascript file that has the following code: $(document).ready(function() { $('img#busy').hide(); $('div#available').hide(); $('div#not_available').hide(); $("button#check").click(function() { var available = checkUsername($("input#txtUsername").val()); if (available == "1") { $("div#available").show(); $("div#not_available").hide(); } else { $("div#available").hide(); $("div#not_available").show(); } }); }); function checkUsername(username) { $.ajax({ type: "POST", url: "/SomeController/SomeAction", data: { "id": username }, timeout: 3000, async: false, beforeSend: function() { $("button#check").hide(); $("img#busy").show(); }, complete: function() { $("button#check").show(); $("img#busy").hide(); }, cache: false, success: function(result) { return result; }, error: function(error) { $("img#busy").hide(); $("button#check").show(); alert("Some problems have occured. Please try again later: " + error); } }); }

  • Switch between speakerphone and headset on Android

    Hi! I wish to know if there is a way, using which we can switch between the speaker and headset dynamically in an android application. I am using this sample code, I found online for my experiments final float frequency = 440; float increment = (float)(2*Math.PI) * frequency / 44100; // angular increment for each sample float angle = 0; AndroidAudioDevice device = new AndroidAudioDevice( ); AudioManager am = (AudioManager)getSystemService(AUDIO_SERVICE); am.setMode(AudioManager.MODE_IN_CALL); float samples[] = new float[1024]; int count = 0; while( count < 10 ) { count++; for( int i = 0; i < samples.length; i++ ) { samples[i] = (float)Math.sin( angle ) ; angle += increment; } device.writeSamples( samples ); } device.stop(); am.setMode(AudioManager.MODE_NORMAL); ---- next class public class AndroidAudioDevice { AudioTrack track; short[] buffer = new short[1024]; public AndroidAudioDevice( ) { int minSize =AudioTrack.getMinBufferSize( 44100, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT ); track = new AudioTrack( AudioManager.STREAM_VOICE_CALL, 44100, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, minSize, AudioTrack.MODE_STREAM); track.play(); } public void writeSamples(float[] samples) { fillBuffer( samples ); track.write( buffer, 0, samples.length ); } private void fillBuffer( float[] samples ) { if( buffer.length < samples.length ) buffer = new short[samples.length]; for( int i = 0; i < samples.length; i++ ) buffer[i] = (short)(samples[i] * Short.MAX_VALUE);; } public void stop() { track.stop(); } } As per my understanding this should play audio on headset, because we have not enabled the speaker phone. However, the audio is playing on the speaker phone. 1 Am I doing something wrong here? 2 What would be a way to switch between internal speaker and speaker phone dynamically for same code peice Any help will be appreciated.

  • AngularJS recursive directive with a dynamic HTML template (bounty)

    - by Nazar Sobchuk
    I have a realy hard task here. I am working on an AngularJS web app, which is capable of sending different HTTP methods to our project's Restful Web Service and receiving responses in JSON. Basicaly it looks like this: You can create some REST resource from this application. Let's say an exam. To create an exam - you pick a resource from a list of available resources. This triggers a function, that sends a request to localhost:8080/STEP/api/explain/resorceName and gets a description for this resource. Description looks like this: http://jsonblob.com/534fc022e4b0bb44248d6460 After receiving a response - I start building input fields like follows (allFields - array of field objects for this resource, enumValues - enum values for resource's field if it's property isEnum = true): <div ng-repeat="field in allFields"> <div ng-show={{!field.isEnum}}> <p ng-show={{field.isRequired}}>{{field.name}}*: </p> <p ng-show={{!field.isRequired}}>{{field.name}}: </p> <input type="text" ng-model="updateEntityResource[field.name]" ng-change="getUpdateEntityAsText()" class="form-control" placeholder="{{parseClassName(field.type)}}"> </div> <div ng-show={{field.isEnum}}> <p ng-show={{field.isRequired}}>{{field.name}}*: </p> <p ng-show={{!field.isRequired}}>{{field.name}}: </p> <select ng-model="updateEntityResource[field.name]" ng-change="getUpdateEntityAsText()" class="form-control"> <option></option> <option ng-repeat="enumValue in field.enumValues" label={{enumValue.name}}>{{enumValue.ordinal}}</option> </select> </div> </div> Now, the problem. I need to create a recursive directive, which would be capable of generating fields in such maner as described above for every resource's field that has "restResourceName" not null. To get all it's fields you just send a request to localhost:8080/STEP/api/explain/restResourceName and get similar JSON response as shown above, which is then used to build HTML elements for inputing values into model. Does anyone know how this can be achieved using angular recursive directive? Every useful answer is highly appreciated and evaluated. The correct answer will get +50 or I will start a bounty, because I'm realy stuck with this for 2 days. If you need any additional info - let me know. Thank you.

  • making a password-only auth with bcrypt and mongoose

    - by user3081123
    I want to create service that let you login only with password. You type a password and if this password exists - you are logged in and if it's not - username is generated and password is encrypted. I'm having some misunderstandings and hope someone would help me to show where I'm mistaken. I guess, it would look somewhat like this in agularjs First we receive a password in login controller. $scope.signup = function() { var user = { password: $scope.password, }; $http.post('/auth/signup', user); }; Send it via http.post and get in in our node server file. We are provided with a compare password bcrypt function userSchema.methods.comparePassword = function(candidatePassword, cb) { bcrypt.compare(candidatePassword, this.password, function(err, isMatch) { if (err) return cb(err); cb(null, isMatch); }); }; So right now we are creating function to catch our http request app.post('/auth/signup', function(req, res, next) { Inside we use a compair password function to realize if such password exists or not yet. So we have to encrypt a password with bcrypt to make a comparison First we hash it same way as in .pre var encPass; bcrypt.genSalt(10, function(err, salt) { if (err) return next(err); bcrypt.hash(req.body.password, salt, function(err, hash) { if (err) return next(err); encPass=hash; )}; )}; We have encrypted password stored in encPass so now we follow to finding a user in database with this password User.findOne({ password: encPass }, function(err, user) { if (user) { //user exists, it means we should pass an ID of this user to a controller to display it in a view. I don't know how. res.send({user.name}) //like this? How should controller receive this? With $http.post? } else { and now if user doesn't exist - we should create it with user ID generated by my function var nUser = new User({ name: generId(), password: req.body.password }); nUser.save(function(err) { if (err) return next(err); )}; )}; )}; Am I doing anything right? I'm pretty new to js and angular. If so - how do I throw a username back at controller? If someone is interested - this service exists for 100+ symbol passphrases so possibility of entering same passphrase as someone else is miserable. And yeah, If someone logged in under 123 password - the other guy will log in as same user if he entered 123 password, but hey, you are warned to make a big passphrase. So I'm confident about the idea and I only need a help with understanding and realization.

  • Learning AngularJS by Example – The Customer Manager Application

    - by dwahlin
    I’m always tinkering around with different ideas and toward the beginning of 2013 decided to build a sample application using AngularJS that I call Customer Manager. It’s not exactly the most creative name or concept, but I wanted to build something that highlighted a lot of the different features offered by AngularJS and how they could be used together to build a full-featured app. One of the goals of the application was to ensure that it was approachable by people new to Angular since I’ve never found overly complex applications great for learning new concepts. The application initially started out small and was used in my AngularJS in 60-ish Minutes video on YouTube but has gradually had more and more features added to it and will continue to be enhanced over time. It’ll be used in a new “end-to-end” training course my company is working on for AngularjS as well as in some video courses that will be coming out. Here’s a quick look at what the application home page looks like: In this post I’m going to provide an overview about how the application is organized, back-end options that are available, and some of the features it demonstrates. I’ve already written about some of the features so if you’re interested check out the following posts: Building an AngularJS Modal Service Building a Custom AngularJS Unique Value Directive Using an AngularJS Factory to Interact with a RESTful Service Application Structure The structure of the application is shown to the right. The  homepage is index.html and is located at the root of the application folder. It defines where application views will be loaded using the ng-view directive and includes script references to AngularJS, AngularJS routing and animation scripts, plus a few others located in the Scripts folder and to custom application scripts located in the app folder. The app folder contains all of the key scripts used in the application. There are several techniques that can be used for organizing script files but after experimenting with several of them I decided that I prefer things in folders such as controllers, views, services, etc. Doing that helps me find things a lot faster and allows me to categorize files (such as controllers) by functionality. My recommendation is to go with whatever works best for you. Anyone who says, “You’re doing it wrong!” should be ignored. Contrary to what some people think, there is no “one right way” to organize scripts and other files. As long as the scripts make it down to the client properly (you’ll likely minify and concatenate them anyway to reduce bandwidth and minimize HTTP calls), the way you organize them is completely up to you. Here’s what I ended up doing for this application: Animation code for some custom animations is located in the animations folder. In addition to AngularJS animations (which are defined using CSS in Content/animations.css), it also animates the initial customer data load using a 3rd party script called GreenSock. Controllers are located in the controllers folder. Some of the controllers are placed in subfolders based upon the their functionality while others are placed at the root of the controllers folder since they’re more generic:   The directives folder contains the custom directives created for the application. The filters folder contains the custom filters created for the application that filter city/state and product information. The partials folder contains partial views. This includes things like modal dialogs used in the application. The services folder contains AngularJS factories and services used for various purposes in the application. Most of the scripts in this folder provide data functionality. The views folder contains the different views used in the application. Like the controllers folder, the views are organized into subfolders based on their functionality:   Back-End Services The Customer Manager application (grab it from Github) provides two different options on the back-end including ASP.NET Web API and Node.js. The ASP.NET Web API back-end uses Entity Framework for data access and stores data in SQL Server (LocalDb). The other option on the back-end is Node.js, Express, and MongoDB.   Using the ASP.NET Web API Back-End To run the application using ASP.NET Web API/SQL Server back-end open the .sln file at the root of the project in Visual Studio 2012 or higher (the free Express 2013 for Web version is fine). Press F5 and a browser will automatically launch and display the application. Using the Node.js Back-End To run the application using the Node.js/MongoDB back-end follow these steps: In the CustomerManager directory execute 'npm install' to install Express, MongoDB and Mongoose (package.json). Load sample data into MongoDB by performing the following steps: Execute 'mongod' to start the MongoDB daemon Navigate to the CustomerManager directory (the one that has initMongoCustData.js in it) then execute 'mongo' to start the MongoDB shell Enter the following in the mongo shell to load the seed files that handle seeding the database with initial data: use custmgr load("initMongoCustData.js") load("initMongoSettingsData.js") load("initMongoStateData.js") Start the Node/Express server by navigating to the CustomerManager/server directory and executing 'node app.js' View the application at http://localhost:3000 in your browser. Key Features The Customer Manager application certainly doesn’t cover every feature provided by AngularJS (as mentioned the intent was to keep it as simple as possible) but does provide insight into several key areas: Using factories and services as re-useable data services (see the app/services folder) Creating custom directives (see the app/directives folder) Custom paging (see app/views/customers/customers.html and app/controllers/customers/customersController.js) Custom filters (see app/filters) Showing custom modal dialogs with a re-useable service (see app/services/modalService.js) Making Ajax calls using a factory (see app/services/customersService.js) Using Breeze to retrieve and work with data (see app/services/customersBreezeService.js). Switch the application to use the Breeze factory by opening app/services.config.js and changing the useBreeze property to true. Intercepting HTTP requests to display a custom overlay during Ajax calls (see app/directives/wcOverlay.js) Custom animations using the GreenSock library (see app/animations/listAnimations.js) Creating custom AngularJS animations using CSS (see Content/animations.css) JavaScript patterns for defining controllers, services/factories, directives, filters, and more (see any JavaScript file in the app folder) Card View and List View display of data (see app/views/customers/customers.html and app/controllers/customers/customersController.js) Using AngularJS validation functionality (see app/views/customerEdit.html, app/controllers/customerEditController.js, and app/directives/wcUnique.js) More… Conclusion I’ll be enhancing the application even more over time and welcome contributions as well. Tony Quinn contributed the initial Node.js/MongoDB code which is very cool to have as a back-end option. Access the standard application here and a version that has custom routing in it here. Additional information about the custom routing can be found in this post.

  • Cancelling Route Navigation in AngularJS Controllers

    - by dwahlin
    If you’re new to AngularJS check out my AngularJS in 60-ish Minutes video tutorial or download the free eBook. Also check out The AngularJS Magazine for up-to-date information on using AngularJS to build Single Page Applications (SPAs). Routing provides a nice way to associate views with controllers in AngularJS using a minimal amount of code. While a user is normally able to navigate directly to a specific route, there may be times when a user triggers a route change before they’ve finalized an important action such as saving data. In these types of situations you may want to cancel the route navigation and ask the user if they’d like to finish what they were doing so that their data isn’t lost. In this post I’ll talk about a technique that can be used to accomplish this type of routing task.   The $locationChangeStart Event When route navigation occurs in an AngularJS application a few events are raised. One is named $locationChangeStart and the other is named $routeChangeStart (there are other events as well). At the current time (version 1.2) the $routeChangeStart doesn’t provide a way to cancel route navigation, however, the $locationChangeStart event can be used to cancel navigation. If you dig into the AngularJS core script you’ll find the following code that shows how the $locationChangeStart event is raised as the $browser object’s onUrlChange() function is invoked:   $browser.onUrlChange(function (newUrl) { if ($location.absUrl() != newUrl) { if ($rootScope.$broadcast('$locationChangeStart', newUrl, $location.absUrl()).defaultPrevented) { $browser.url($location.absUrl()); return; } $rootScope.$evalAsync(function () { var oldUrl = $location.absUrl(); $location.$$parse(newUrl); afterLocationChange(oldUrl); }); if (!$rootScope.$$phase) $rootScope.$digest(); } }); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The key part of the code is the call to $broadcast. This call broadcasts the $locationChangeStart event to all child scopes so that they can be notified before a location change is made. To handle the $locationChangeStart event you can use the $rootScope.on() function. For this example I’ve added a call to $on() into a function that is called immediately after the controller is invoked:   function init() { //initialize data here.. //Make sure they're warned if they made a change but didn't save it //Call to $on returns a "deregistration" function that can be called to //remove the listener (see routeChange() for an example of using it) onRouteChangeOff = $rootScope.$on('$locationChangeStart', routeChange); } This code listens for the $locationChangeStart event and calls routeChange() when it occurs. The value returned from calling $on is a “deregistration” function that can be called to detach from the event. In this case the deregistration function is named onRouteChangeOff (it’s accessible throughout the controller). You’ll see how the onRouteChangeOff function is used in just a moment.   Cancelling Route Navigation The routeChange() callback triggered by the $locationChangeStart event displays a modal dialog similar to the following to prompt the user:     Here’s the code for routeChange(): function routeChange(event, newUrl) { //Navigate to newUrl if the form isn't dirty if (!$scope.editForm.$dirty) return; var modalOptions = { closeButtonText: 'Cancel', actionButtonText: 'Ignore Changes', headerText: 'Unsaved Changes', bodyText: 'You have unsaved changes. Leave the page?' }; modalService.showModal({}, modalOptions).then(function (result) { if (result === 'ok') { onRouteChangeOff(); //Stop listening for location changes $location.path(newUrl); //Go to page they're interested in } }); //prevent navigation by default since we'll handle it //once the user selects a dialog option event.preventDefault(); return; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Looking at the parameters of routeChange() you can see that it accepts an event object and the new route that the user is trying to navigate to. The event object is used to prevent navigation since we need to prompt the user before leaving the current view. Notice the call to event.preventDefault() at the end of the function. The modal dialog is shown by calling modalService.showModal() (see my previous post for more information about the custom modalService that acts as a wrapper around Angular UI Bootstrap’s $modal service). If the user selects “Ignore Changes” then their changes will be discarded and the application will navigate to the route they intended to go to originally. This is done by first detaching from the $locationChangeStart event by calling onRouteChangeOff() (recall that this is the function returned from the call to $on()) so that we don’t get stuck in a never ending cycle where the dialog continues to display when they click the “Ignore Changes” button. A call is then made to $location.path(newUrl) to handle navigating to the target view. If the user cancels the operation they’ll stay on the current view. Conclusion The key to canceling routes is understanding how to work with the $locationChangeStart event and cancelling it so that route navigation doesn’t occur. I’m hoping that in the future the same type of task can be done using the $routeChangeStart event but for now this code gets the job done. You can see this code in action in the Customer Manager application available on Github (specifically the customerEdit view). Learn more about the application here.

  • Ball to Ball Collision - Detection and Handling

    - by Simucal
    With the help of the Stack Overflow community I've written a pretty basic-but fun physics simulator. You click and drag the mouse to launch a ball. It will bounce around and eventually stop on the "floor". My next big feature I want to add in is ball to ball collision. The ball's movement is broken up into a x and y speed vector. I have gravity (small reduction of the y vector each step), I have friction (small reduction of both vectors each collision with a wall). The balls honestly move around in a surprisingly realistic way. I guess my question has two parts: What is the best method to detect ball to ball collision? Do I just have an O(n^2) loop that iterates over each ball and checks every other ball to see if it's radius overlaps? What equations do I use to handle the ball to ball collisions? Physics 101 How does it effect the two balls speed x/y vectors? What is the resulting direction the two balls head off in? How do I apply this to each ball? Handling the collision detection of the "walls" and the resulting vector changes were easy but I see more complications with ball-ball collisions. With walls I simply had to take the negative of the appropriate x or y vector and off it would go in the correct direction. With balls I don't think it is that way. Some quick clarifications: for simplicity I'm ok with a perfectly elastic collision for now, also all my balls have the same mass right now, but I might change that in the future. In case anyone is interested in playing with the simulator I have made so far, I've uploaded the source here (EDIT: Check the updated source below). Edit: Resources I have found useful 2d Ball physics with vectors: 2-Dimensional Collisions Without Trigonometry.pdf 2d Ball collision detection example: Adding Collision Detection Success! I have the ball collision detection and response working great! Relevant code: Collision Detection: for (int i = 0; i < ballCount; i++) { for (int j = i + 1; j < ballCount; j++) { if (balls[i].colliding(balls[j])) { balls[i].resolveCollision(balls[j]); } } } This will check for collisions between every ball but skip redundant checks (if you have to check if ball 1 collides with ball 2 then you don't need to check if ball 2 collides with ball 1. Also, it skips checking for collisions with itself). Then, in my ball class I have my colliding() and resolveCollision() methods: public boolean colliding(Ball ball) { float xd = position.getX() - ball.position.getX(); float yd = position.getY() - ball.position.getY(); float sumRadius = getRadius() + ball.getRadius(); float sqrRadius = sumRadius * sumRadius; float distSqr = (xd * xd) + (yd * yd); if (distSqr <= sqrRadius) { return true; } return false; } public void resolveCollision(Ball ball) { // get the mtd Vector2d delta = (position.subtract(ball.position)); float d = delta.getLength(); // minimum translation distance to push balls apart after intersecting Vector2d mtd = delta.multiply(((getRadius() + ball.getRadius())-d)/d); // resolve intersection -- // inverse mass quantities float im1 = 1 / getMass(); float im2 = 1 / ball.getMass(); // push-pull them apart based off their mass position = position.add(mtd.multiply(im1 / (im1 + im2))); ball.position = ball.position.subtract(mtd.multiply(im2 / (im1 + im2))); // impact speed Vector2d v = (this.velocity.subtract(ball.velocity)); float vn = v.dot(mtd.normalize()); // sphere intersecting but moving away from each other already if (vn > 0.0f) return; // collision impulse float i = (-(1.0f + Constants.restitution) * vn) / (im1 + im2); Vector2d impulse = mtd.multiply(i); // change in momentum this.velocity = this.velocity.add(impulse.multiply(im1)); ball.velocity = ball.velocity.subtract(impulse.multiply(im2)); } Source Code: Complete source for ball to ball collider. Binary: Compiled binary in case you just want to try bouncing some balls around. If anyone has some suggestions for how to improve this basic physics simulator let me know! One thing I have yet to add is angular momentum so the balls will roll more realistically. Any other suggestions? Leave a comment!
