  • If I'm running my App Engine app on localhost, will I not see a value for X-AppEngine-Country?

    - by Bartholomew
    According to the Release Notes: All user request have an X-AppEngine-Country header which contains the ISO-3166-1 alpha-2 country code for the user, based on the IP address of the client request. My app is running on localhost with the 1.5.1 Java release which contains the X-AppEngine-Country header but I don't seem to be receiving any value for this header in my requests. Do I have to deploy the app to a production instance to test this feature?

  • Works on development server but it doesn't on Google App Engine (Sessions).

    - by grep
    Hi, I have this code that works just fine on the development server but when I deploy the application, the session isn't created. What am I doing wrong? HttpSession session = req.getSession(true); session.setAttribute("loggedIn", new String("true")); Edit: The sessions are enabled. What I realized now is that the _ah_SESSION variable is not being created, not even on the development server (although it works).

  • How can I scale movement physics functions to frames per second (in a game engine)?

    - by Richard
    I am working on a game in Javascript (HTML5 Canvas). I implemented a simple algorithm that allows an object to follow another object with basic physics mixed in (a force vector to drive the object in the right direction, and the velocity stacks momentum, but is slowed by a constant drag force). At the moment, I set it up as a rectangle following the mouse (x, y) coordinates. Here's the code: // rectangle x, y position var x = 400; // starting x position var y = 250; // starting y position var FPS = 60; // frames per second of the screen // physics variables: var velX = 0; // initial velocity at 0 (not moving) var velY = 0; // not moving var drag = 0.92; // drag force reduces velocity by 8% per frame var force = 0.35; // overall force applied to move the rectangle var angle = 0; // angle in which to move // called every frame (at 60 frames per second): function update(){ // calculate distance between mouse and rectangle var dx = mouseX - x; var dy = mouseY - y; // calculate angle between mouse and rectangle var angle = Math.atan(dy/dx); if(dx < 0) angle += Math.PI; else if(dy < 0) angle += 2*Math.PI; // calculate the force (on or off, depending on user input) var curForce; if(keys[32]) // SPACE bar curForce = force; // if pressed, use 0.35 as force else curForce = 0; // otherwise, force is 0 // increment velocty by the force, and scaled by drag for x and y velX += curForce * Math.cos(angle); velX *= drag; velY += curForce * Math.sin(angle); velY *= drag; // update x and y by their velocities x += velX; y += velY; And that works fine at 60 frames per second. Now, the tricky part: my question is, if I change this to a different framerate (say, 30 FPS), how can I modify the force and drag values to keep the movement constant? That is, right now my rectangle (whose position is dictated by the x and y variables) moves at a maximum speed of about 4 pixels per second, and accelerates to its max speed in about 1 second. BUT, if I change the framerate, it moves slower (e.g. 30 FPS accelerates to only 2 pixels per frame). So, how can I create an equation that takes FPS (frames per second) as input, and spits out correct "drag" and "force" values that will behave the same way in real time? I know it's a heavy question, but perhaps somebody with game design experience, or knowledge of programming physics can help. Thank you for your efforts. jsFiddle: http://jsfiddle.net/BadDB

  • ASP.NET JavaScript Routing for ASP.NET MVC–Constraints

    - by zowens
    If you haven’t had a look at my previous post about ASP.NET routing, go ahead and check it out before you read this post: http://weblogs.asp.net/zowens/archive/2010/12/20/asp-net-mvc-javascript-routing.aspx And the code is here: https://github.com/zowens/ASP.NET-MVC-JavaScript-Routing   Anyways, this post is about routing constraints. A routing constraint is essentially a way for the routing engine to filter out route patterns based on the day from the URL. For example, if I have a route where all the parameters are required, I could use a constraint on the required parameters to say that the parameter is non-empty. Here’s what the constraint would look like: Notice that this is a class that inherits from IRouteConstraint, which is an interface provided by System.Web.Routing. The match method returns true if the value is a match (and can be further processed by the routing rules) or false if it does not match (and the route will be matched further along the route collection). Because routing constraints are so essential to the route matching process, it was important that they be part of my JavaScript routing engine. But the problem is that we need to somehow represent the constraint in JavaScript. I made a design decision early on that you MUST put this constraint into JavaScript to match a route. I didn’t want to have server interaction for the URL generation, like I’ve seen in so many applications. While this is easy to maintain, it causes maintenance issues in my opinion. So the way constraints work in JavaScript is that the constraint as an object type definition is set on the route manager. When a route is created, a new instance of the constraint is created with the specific parameter. In its current form the constraint function MUST return a function that takes the route data and will return true or false. You will see the NotEmpty constraint in a bit. Another piece to the puzzle is that you can have the JavaScript exist as a string in your application that is pulled in when the routing JavaScript code is generated. There is a simple interface, IJavaScriptAddition, that I have added that will be used to output custom JavaScript. Let’s put it all together. Here is the NotEmpty constraint. There’s a few things at work here. The constraint is called “notEmpty” in JavaScript. When you add the constraint to a parameter in your C# code, the route manager generator will look for the JsConstraint attribute to look for the name of the constraint type name and fallback to the class name. For example, if I didn’t apply the “JsConstraint” attribute, the constraint would be called “NotEmpty”. The JavaScript code essentially adds a function to the “constraintTypeDefs” object on the “notEmpty” property (this is how constraints are added to routes). The function returns another function that will be invoked with routing data. Here’s how you would use the NotEmpty constraint in C# and it will work with the JavaScript routing generator. The only catch to using route constraints currently is that the following is not supported: The constraint will work in C# but is not supported by my JavaScript routing engine. (I take pull requests so if you’d like this… go ahead and implement it).   I just wanted to take this post to explain a little bit about the background on constraints. I am looking at expanding the current functionality, but for now this is a good start. Thanks for all the support with the JavaScript router. Keep the feedback coming!

  • Facebook: Sending private messages to FB profile from a static website [migrated]

    - by Frondor
    I need to setup a static website for people to: Complete a form. And using anything from Facebook API, GET the form output via message to a Facebook Profile. I've been punching my head against "facebook developers" page all night long and can't find out how to do it. Seems quite easy, but the problem is that I don't know if you'll get my point :) Like the Send Dialog feature, you can set a certain user as recipient which will be displayed on the "To:" field once the dialog appears. FB.ui({ method: 'send', to: 'UserID', link: 'http://www.nytimes.com/2011/06/15/arts/people-argue-just-to-win-scholars-assert.html', }); Ok, All I need is to be able to use the same behavior but instead of setting a "to:" parameter, I'd like to set a "message:" parameter. I don't know how I can solve this becuase there's no parameter like this on the API actually. This is what I need to build (It's a prototype, this code won't work) <form action="mysite.com" id="order"> <input type="radio" name="chocolate" value="white">White <br/> <input type="radio" name="chocolate" value="black">Black <br/> <input type="submit" value="Order" /> </form> jQuery gets the values $(document).ready(function() { $("#order").on("submit", function(e) { e.preventDefault(); var formOutput = $(this).serialize(); var order = "I'd like to eat" + formOutput + "chocolate"; }); }); Facebook sdk sends this output ('order' string) FB.ui({ method: 'send', //or whatever to: 'UserID', message: order, //Its just an example, note the variable coming from the form link: 'http://www.nytimes.com/2011/06/15/arts/people-argue-just-to-win-scholars-assert.html', }); As we all know, what I wrote isn't possible, so I'm asking for any alternative solution if somebody can give me, I'm not very friendly with facebook APIs :) I though in another solution which consist in using the form output directly on the 'link:' parameter of FB.ui and then reading it with jQuery on some landing page. For example, on the message sent, the linked content redirects to this URL: http://mysite.com/dashboard.html?chocolate=white and the dashboard page source code: <script> var choco = getUrlParameter('chocolate'); $("#dashboard").text("This person wants" + choco + "chocolate") </script> <div id="dashboard"></div> And this way, I will be able to see which kind of chocolate the person selected by parsing some parameters on the URL when clicking on the link section of the message: using a code like this: FB.ui({ method: 'send', //or whatever to: 'MyUserID', link: 'http://mysite.com/dashboard.html?chocolate=white', }); But no this try, my biggest problem is that I don't know how to dynamically "customize" that "link:" paramenter with jQuery. I think the best solution is to use a code like this along with the dashboard page in order to "translate" the shared URLs and see what kind of chocolate people are demanding xD FB.ui({ //declaring a variable (example) var string = getFormData().serialize; var orderString = "mysite.com/dashboard.html?" + string; // end the variables // start facebook API code method: 'send', //or whatever to: 'MyUserID', link: orderString, }); I was working here until I gave up and started to post this http://jsfiddle.net/Frondor/sctepn06/2/ Thanks in advance, I'll love you for ever if you help me solving this :D

  • Chaining CSS classes in IE6 - Trying to find a jQuery solution?

    - by Mike Baxter
    Right, perhaps I ask the impossible? I consider myself fairly new to Javscript and jQuery, but that being said, I have written some fairly complex code recently so I am definitely getting there... however I am now possed with a rather interesting issue at my current freelance contract. The previous web coder has taken a Grid-960 approach to the HTML and as a result has used chained classes to style many of the elements. The example below is typical of what can be found in the code: <div class='blocks four-col-1 orange highlight'>Some content</div> And in the css there will be different declarations for: (not actual css... but close enough) .blocks {margin-right:10px;} .orange {background-image:url(someimage.jpg);} .highlight {font-weight:bold;} .four-col-1 {width:300px;} and to make matters worse... this is in the CSS: .blocks.orange.highlight {background-colour:#dd00ff;} Anyone not familiar with this particular bug can read more on it here: http://www.ryanbrill.com/archives/multiple-classes-in-ie/ it is very real and very annoying. Without wanting to go into the merrits of not chaining classes (I told them this, but it is no longer feasible to change their approach... 100 hand coded pages into a 150 page website, no CMS... sigh) and without the luxury of being able to change the way these blocks are styled... can anyone advise me on the complexity and benefits between any of my below proposed approaches or possible other options that would adequately solve this problem. Potential Solution 1 Using conditional comments I am considering loading a jquery script only for IE6 that: Reads the class of all divs in a certain section of the page and pushes to an array creates empty boxes off screen with only one of the classes applied at a time Reads the applied CSS values for each box Re-applies these styles to the individual box, somehow bearing in mind the order in which they are called and overwriting conflicting instructions as required Potential Solution 2 read the class of all divs in a certain section of the page and push to an array Scan the document for links to style sheets Ajax grab the stylesheets and traverse looking for matching names to those in class array Apply styles as needed Potential Solution 3 Create an IE6 only stylesheet containing the exact style to be applied as a unique name (ie: class='blocks orange highlight' becomes class='blocks-orange-highlight') Traverse the document in IE6 and convert all spaces in class declarations to hyphens and reapply classes based on new style name Summary: Solution 1 allows the people at this company to apply any styles in the future and the script will adjust as needed. However it does not allow for the chained style to be added, only the individual style... it is also processor intensive and time consuming, but also the most likely to be converted into a plugin that could be used the world over Solution 2 is a potential nightmare to code. But again will allow for an endless number of updates without breaking Solution 3 will require someone at the companty to hardcode the new styles every time they make a change, and if they don't, IE6 will break. Ironically the site, whilst needing to conform to IE6 in a limited manner, does not need to run wihtout javascript (they've made the call... have JS or go away), so consider all jQuery and JS solutions to be 'game on'. Did I mention how much i hate IE6? Anyway... any thoughts or comments would be appreciated. I will continue to develop my own solution and if I discover one that can be turned into a jQuery plugin I will post it here in the comments. Regards, Mike.

  • In the following list, how do I prevent jQuery from interacting with part of it.

    - by kylex
    I have the following list structure: <ul> <li>One</li> <li class="topActive">Two <ul> <li class="active">Two-1 <ul> <li>Two-1-1</li> </ul> </li> <li>Two-2</li> </ul> </li> <li>Three <ul> <li>Three-1</li> </ul> </li> </ul> with the following jQuery: $("ul>li>ul").hide(); $("ul>li>ul>li>ul").hide(); $("ul>li>ul>li>ul>ul>li").hide(); $('.active').parents().show();????????? $("ul>li").hoverIntent( function(){ $(this).children('ul').slideDown('fast'); }, function(){ $(this).children('ul').slideUp('fast'); } ); $("ul>li>ul>li").hoverIntent( function(){ $(this).children('ul').slideDown('fast'); }, function(){ $(this).children('ul').slideUp('fast'); } ); What I would like is this: When an li class is topActive, everything within that class down to the current class can not be affected by the jQuery that causes the list to slide up and down. so in the case provided the following would show, along with the top level: One Two Two-1 Two-2 Three And when I mouse over either, Two, or Two-1 or Two-2 nothing happens, but if I mouse over Three, the jQuery will cause it to slide up or slide down. In this example: <ul> <li>One</li> <li class="topActive">Two <ul> <li class="active">Two-1 <ul> <li>Two-1-1</li> </ul> </li> <li>Two-2</li> </ul> </li> <li>Three <ul> <li>Three-1</li> </ul> </li> </ul> When I mouseover Two-1, it will slide down, but when I mouse out Two-1 will remain. One Two Two-1 Two-2 Three Any suggestsions for either a CSS or jQuery implementation (or mixture of the two)?

  • SQL SERVER – Subquery or Join – Various Options – SQL Server Engine knows the Best

    - by pinaldave
    This is followup post of my earlier article SQL SERVER – Convert IN to EXISTS – Performance Talk, after reading all the comments I have received I felt that I could write more on the same subject to clear few things out. First let us run following four queries, all of them are giving exactly same resultset. USE AdventureWorks GO -- use of = SELECT * FROM HumanResources.Employee E WHERE E.EmployeeID = ( SELECT EA.EmployeeID FROM HumanResources.EmployeeAddress EA WHERE EA.EmployeeID = E.EmployeeID) GO -- use of in SELECT * FROM HumanResources.Employee E WHERE E.EmployeeID IN ( SELECT EA.EmployeeID FROM HumanResources.EmployeeAddress EA WHERE EA.EmployeeID = E.EmployeeID) GO -- use of exists SELECT * FROM HumanResources.Employee E WHERE EXISTS ( SELECT EA.EmployeeID FROM HumanResources.EmployeeAddress EA WHERE EA.EmployeeID = E.EmployeeID) GO -- Use of Join SELECT * FROM HumanResources.Employee E INNER JOIN HumanResources.EmployeeAddress EA ON E.EmployeeID = EA.EmployeeID GO Let us compare the execution plan of the queries listed above. Click on image to see larger image. It is quite clear from the execution plan that in case of IN, EXISTS and JOIN SQL Server Engines is smart enough to figure out what is the best optimal plan of Merge Join for the same query and execute the same. However, in the case of use of Equal (=) Operator, SQL Server is forced to use Nested Loop and test each result of the inner query and compare to outer query, leading to cut the performance. Please note that here I no mean suggesting that Nested Loop is bad or Merge Join is better. This can very well vary on your machine and amount of resources available on your computer. When I see Equal (=) operator used in query like above, I usually recommend to see if user can use IN or EXISTS or JOIN. As I said, this can very much vary on different system. What is your take in above query? I believe SQL Server Engines is usually pretty smart to figure out what is ideal execution plan and use it.

  • The right way to start out in game development/design [closed]

    - by Marco Sacristão
    Greetings everyone I'm a 19 year old student looking for some help in the field of game development. This question may or may not seem a bit overused, but the fact is that game development has been my life long dream, and after several hours of search I've realized that I've been going in circles for the past three or four months whilst doing such research on how to really get down and dirty with game development, therefor I decided to ask you guys if you could help me out at all. Let me start off with some information about me and things i've already learned about GameDev which might help you out on helping me out (wordplay!): I'm not an expert programmer, but I do have knowledge on how to program in several languages including C and Java (Currently learning Java in my degree in Computer Engineering), but my methodology might not be most correct in terms of syntax (hence my difficulty in starting out, i'm afraid that the starting point might not be the most correct, and it would deploy a wrongful development methodology that would be to corrected later on, in terms of game development or other projects). I have yet to work in a project as large as a game, never in my learning curve of programming I've done a project to the scale of a video game, only very small software (PHP Front-ends and Back-ends, with some basic JQuery and CSS knowledge). I'm not the biggest mathematician or physicist, but I already know that is not a problem, because there are several game engines already available for use and integration with home-made projects (Box2D, etc). I've also learned about some libraries that could be included in said projects, to ease out some process in game development, like SDL for example. I do not know how sprites, states, particles or any specific game-related techniques work. With that being said, you can see that I have some ideas on game development, but I have absolutely no clue on how to design and produce a game, or even how game-like mechanics work. It does not have to be a complex game just to start out, I'd rather learn the basic of game design (Like 2D drawing, tiling, object collision) and test that out in a language that I feel comfortable in which could be later on migrated to other platforms, as long that what I've learned is the correct way to do things, and not just something that I've learned from some guy on Youtube by replicating that code on the video. I'm sorry if my question is not in the best format possible, but I've got so many questions on my mind that are still un-answered that I don't know were to start! Thank you for reading.

  • Loading Obj Files in Soya3d engine

    - by John Riselvato
    I recently just found soya3d and from what i have seen through the tutorials i will be able to make exactly what i wanted with python skills. Now i have built this map generator. The only issue is that i can not manage to understand from any documents how to load obj files. At first i figured that i had to convert it to a .data file, but i dont understand how to do this. I just want to load a simple model of a house. I tried using the soya_editor, but i can not figure out at all how to do anything with that. Heres my script so far: import sys, os, os.path, soya, soya.sdlconst width, height = 760, 375 soya.init("Generator 0.1", width, height) soya.path.append(os.path.join(os.path.dirname(sys.argv[0]), "data")) scene = soya.World() model = soya.model.get("house") light = soya.Light(scene) light.set_xyz(0.5, 0.0, 2.0) camera = soya.Camera(scene) camera.z = 2.0 soya.set_root_widget(camera) soya.MainLoop(scene).main_loop() house is in .obj form at folder data/models The error i get is: Traceback (most recent call last): File "introduction.py", line 7, in <module> model = soya.Model.get("house") File "/usr/lib/pymodules/python2.6/soya/__init__.py", line 259, in get return klass._alls.get(filename) or klass._alls.setdefault(filename, klass.load(filename)) File "/usr/lib/pymodules/python2.6/soya/__init__.py", line 268, in load dirname = klass._get_directory_for_loading_and_check_export(filename) File "/usr/lib/pymodules/python2.6/soya/__init__.py", line 194, in _get_directory_for_loading_and_check_export dirname = klass._get_directory_for_loading(filename, ext) File "/usr/lib/pymodules/python2.6/soya/__init__.py", line 171, in _get_directory_for_loading raise ValueError("Cannot find a %s named %s!" % (klass, filename)) ValueError: Cannot find a <class 'soya.Model'> named house! * Soya3D * Quit... So i am figuring that because i dont understand how to turn my files into .data files, i will need to learn that. So my question is, how do i use my own models?

    show engine innodb status; is unusable in MySQL Workbench, as shown here: =====================================120329 12:39:32 INNODB MONITOR OUTPUT=====================================Per second averages calculated from the last 17 seconds-----------------BACKGROUND THREAD-----------------srv_master_thread loops: 192438... However show engine innodb status \G is great on the mysql command line client. Is there any \G equivalent on MySQL workbench or better way to get this information?

  • Can LittleBigPlanet2's engine be used for other ?

    - by Bill
    LittleBigPlanet2 just came out. I've worked with the original LBP level editor a bit and really enjoyed it. I've read that LBP2's featureset in the game is much richer; is it possible to use these advanced features to create different sorts of game other than just a regular platformer? I imagine that something along the lines of a Breakout clone would definitely be manageable, but I'm interested in hearing more about the capabilities of the platform.

  • Tile engine Texture not updating when numbers in array change

    - by Corey
    I draw my map from a txt file. I am using java with slick2d library. When I print the array the number changes in the array, but the texture doesn't change. public class Tiles { public Image[] tiles = new Image[5]; public int[][] map = new int[64][64]; public Image grass, dirt, fence, mound; private SpriteSheet tileSheet; public int tileWidth = 32; public int tileHeight = 32; public void init() throws IOException, SlickException { tileSheet = new SpriteSheet("assets/tiles.png", tileWidth, tileHeight); grass = tileSheet.getSprite(0, 0); dirt = tileSheet.getSprite(7, 7); fence = tileSheet.getSprite(2, 0); mound = tileSheet.getSprite(2, 6); tiles[0] = grass; tiles[1] = dirt; tiles[2] = fence; tiles[3] = mound; int x=0, y=0; BufferedReader in = new BufferedReader(new FileReader("assets/map.dat")); String line; while ((line = in.readLine()) != null) { String[] values = line.split(","); x = 0; for (String str : values) { int str_int = Integer.parseInt(str); map[x][y]=str_int; //System.out.print(map[x][y] + " "); x++; } //System.out.println(""); y++; } in.close(); } public void update(GameContainer gc) { } public void render(GameContainer gc) { for(int y = 0; y < map.length; y++) { for(int x = 0; x < map[0].length; x ++) { int textureIndex = map[x][y]; Image texture = tiles[textureIndex]; texture.draw(x*tileWidth,y*tileHeight); } } } } Mouse Picking Where I change the number in the array Input input = gc.getInput(); gc.getInput().setOffset(cameraX-400, cameraY-300); float mouseX = input.getMouseX(); float mouseY = input.getMouseY(); double mousetileX = Math.floor((double)mouseX/tiles.tileWidth); double mousetileY = Math.floor((double)mouseY/tiles.tileHeight); double playertileX = Math.floor(playerX/tiles.tileWidth); double playertileY = Math.floor(playerY/tiles.tileHeight); double lengthX = Math.abs((float)playertileX - mousetileX); double lengthY = Math.abs((float)playertileY - mousetileY); double distance = Math.sqrt((lengthX*lengthX)+(lengthY*lengthY)); if(input.isMousePressed(Input.MOUSE_LEFT_BUTTON) && distance < 4) { System.out.println("Clicked"); if(tiles.map[(int)mousetileX][(int)mousetileY] == 1) { tiles.map[(int)mousetileX][(int)mousetileY] = 0; } } I never ask a question until I have tried to figure it out myself. I have been stuck with this problem for two weeks. It's not like this site is made for asking questions or anything. So if you actually try to help me instead of telling me to use a debugger thank you. You either get told you have too much or too little code. Nothing is never enough for the people on here it's as bad as something like reddit. Idk what is wrong all my textures work when I render them it just doesn't update when the number in the array changes. I am obviously debugging when I say that I was printing the array and the number is changing like it should, so it's not a problem with my mouse picking code. It is a problem with my textures, but I don't know what because they all render correctly. That is why I need help.

  • Node.js pour les développeurs jQuery par Marc Buils

    Node.js est souvent associé à la notion de JavaScript Natif (développement JavaScript sans utiliser de framework), ce qui peut faire fuir de nombreux développeurs formés sur jQuery. Je propose donc à tous ces développeurs, qui s'intéressent à Node.js mais qui ne veulent pas perdre la puissance et l'expérience acquise sur jQuery, cet article qui les guidera pas à pas et de façon ludique dans le développement d'un système de messagerie instantanée.
