  • Tile-based maps in AS3

    - by Ashley
    I want to make a tile-based platformer in AS3. I want my game to read an external maps file (in xml or json or somethimg similar) to draw a tile-based map. I've seen loads of tutorials for this in AS2 and other languages, and the few I've found in AS3 are either incomplete or filled with extra unnecessary features. I just want to be able to draw a basic map from sprites in Flash. Any links or information to point me in the right direction would be appreciated.

  • Transformation matrix that maps a window

    - by gbhall
    I'm currently learning OpenGL at uni, and they give us questions to help us learn (these are not worth anything), however I'm stuck on this one question and would have to travel over an hour and a half to uni for an answer. How do I do this question? Please include as many steps as you can, I want to be able to follow exactly how to do this. Find the transformation that maps a window whose lower left corner is at (1,1) and upper right corner is at (3,5) onto: The entire device screen whose dimension is (600, 500) A viewport that has lower left corner at (100,100) and upper right corner at (400,400) Edit: Damn sorry I should have added I am meant to find the matrix, so no code.

  • Google Maps in .NET Problem

    - by H(at)Ni
    Hello, I've been struggling with Google maps till I found that someone implemented a wrapper so that you can use Google Map as an ASP.Net user control which is a great effort indeed. You can download it from this link. However, after using it for a while, I've found out that it is storing the Google map object only once in the session and getting it from there whenever needed which was a problem for me that when you update the map in some page, you'll find it updated on another page. So, I've digged deep in the code and updated it so that it stores the map object with a unique identifier that you set it as a property in the user control object like that: this.googleMapCtrl.ControlID = Guid.NewGuid().ToString(); You can download the updated control files from here. Cheers,

  • google maps based desktop application

    - by dramaticlook
    I want to build a desktop application which has google maps embedded to it. This app should have a thread to read coordinate data online a usb microphone to use. This application will move the google map markers to their new locations based on the data retrieved from online connections on each refresh. As far as I know gmaps has a javascript API so the first idea in my mind was to embed this mapview into a java applet. So the application will run on a browser. Im not sure if this will work. Do you guys have any idea about this or any other advices you might have? Thanks in advance!!!

  • forward rendering and multiple shadow maps

    - by Irbis
    I have two light sources on my scene. I created two fbo's which store depth textures for these lights. A render loop looks like this: bind fbo1 save depth values for first light unbind fbo1 bind fbo2 save depth values for second light unbind fbo2 enable additive blending bind first depth texture render scene bind second depth texture render scene disable additive blending For one light source the program works fine. For many light sources I use an additive blending to acumulate lighting results but then some objects become transparent (for example when an object which is further away from the camera is drawn before an object which is closer to the camera). How to resolve that problem ? How should I accumulate lighting effects for many light sources (many shadow maps) ? P.S. I use OpenGL/GLSL 3.3+

  • How can I fetch Google static maps with TIdHTTP?

    - by cloudstrif3
    I'm trying to return content from maps.google.com from within Delphi 2006 using the TIdHTTP component. My code is as follows procedure TForm1.GetGoogleMap(); var t_GetRequest: String; t_Source: TStringList; t_Stream: TMemoryStream; begin t_Source := TStringList.Create; try t_Stream := TMemoryStream.Create; try t_GetRequest := 'http://maps.google.com/maps/api/staticmap?' + 'center=Brooklyn+Bridge,New+York,NY' + '&zoom=14' + '&size=512x512' + '&maptype=roadmap' + '&markers=color:blue|label:S|40.702147,-74.015794' + '&markers=color:green|label:G|40.711614,-74.012318' + '&markers=color:red|color:red|label:C|40.718217,-73.998284' + '&sensor=false'; IdHTTP1.Post(t_GetRequest, t_Source, t_Stream); t_Stream.SaveToFile('google.html'); finally t_Stream.Free; end; finally t_Source.Free; end; end; However I keep getting the response HTTP/1.0 403 Forbidden. I assume this means that I don't have permission to make this request but if I copy the url into my web browser IE 8, it works fine. Is there some header information that I need or something else?

  • google maps api keys to be set webserver-wide, (as env var? inside apache?)

    - by ~knb
    I have a web site with many virtual hosts and each registered with several domain names (ending in .org, .de), site1.mysite.de, site2.mysite.org Then I have different templating systems based on several programming languages (perl and php) in use on the web server. The Google Maps Api requires a unique Google Maps api key for each vhost. I want to have something like a web-server wide variable $goomapkey that I can call from inside my code. In PHP code, Now I have a kludgy case-analysis solution like $domain = substr($_SERVER['SERVER_NAME'], -3); if (".de" == $domain){ //if ("xxxxxx" eq substr($ENV{SERVER_NAME}, 0, 5)){ // $gookey = "ABQIAAA..."; //} else { //site1.de $gookey = "ABQIAAAA1Js..."; //} } elseif ("dev" == substr($_SERVER['SERVER_NAME'], 0, 3)){ //dev.mysite.org $gookey = "ABQIAAAA1JsSb..."; } else { //www.mysite.org $gookey = "ABQIAAAA1JsS..."; //TODO: Add more keys for each virtual host, for my.machinename.de, IP-address based URL, ... } ... inside my php-based CMS. A non-ideal solution, because it is, php-only, and I still have to set it at several html templates inside the CMS, and there are too many cases. I want the google maps api key to be set by the apache web server who examines the request *early in the request loop before any php page template code is constructed and evaluated. is an environment variable a good solution? which technology should be used to set the $goomapkey variable? I'd prefer mod_perl2 Apache request handler, but the documentation is confusing (many API changes in the past ). Which Apache module could I use? Is there a built-in Apache module that does the same thing?

  • How can I make my Google Maps api v3 address search bar work by hitting the enter button on the keyboard?

    - by Gavin
    I'm developing a webpage and I would just like to make something more user friendly. I have a functional Google Maps api v3 and an address search bar. Currently, I have to use the mouse to select search to initialize the geocoding function. How can I make the map return a placemark by hitting the enter button on my keyboard? I just want to make it as user-friendly as possible. Here is the javascript and div, respectively, I created for the address bar: var geocoder; function initialize() { geocoder = new google.maps.Geocoder (); function codeAddress () { var address = document.getElementById ("address").value; geocoder.geocode ( { 'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results [0].geometry.location); marker.setPosition(results [0].geometry.location); map.setZoom(14); } else { alert("Geocode was not successful for the following reason: " + status); } }); } <div id="geocoder"> <input id="address" type="textbox" value=""> <input type="button" value="Search" onclick="codeAddress()"> </div> Thank you in advance for your help

  • Broken JS Loop with Google Maps...

    - by Oscar Godson
    My code is below, and I had an issue with nearly the same code, and it was fixed here on StackOverflow, but, again, its not working. I haven't changed the working code, but i did wrap it in the for...in loop youll see below. The issue is that no matter what marker I click it always triggers the last marker/infoWindow that was placed. $(function(){ var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 10, center: latlng, disableDefaultUI:true, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $.getJSON('api',function(json){ for (var property in json) { if (json.hasOwnProperty(property)) { var json_data = json[property]; var the_marker = new google.maps.Marker({ title:json_data.item.headline, map:map, clickable:true, position:new google.maps.LatLng( parseFloat(json_data.item.geoarray[0].latitude), parseFloat(json_data.item.geoarray[0].longitude) ) }); var infowindow = new google.maps.InfoWindow({ content: '<div><h1>'+json_data.item.headline+'</h1><p>'+json_data.item.full_content+'</p></div>' }); new google.maps.event.addListener(the_marker, 'click', function() { infowindow.open(map,the_marker); }); } } }); }); Thank you for whoever figures this out!

  • Correct way to import Blueprint's ie.css via DotLess in a Spark view

    - by Chris F
    I am using the Spark View Engine for ASP.NET MVC2 and trying to use Blueprint CSS. The quick guide to Blueprint says to add links to the css files like so: <link rel="stylesheet" href="blueprint/screen.css" type="text/css" media="screen, projection"> <link rel="stylesheet" href="blueprint/print.css" type="text/css" media="print"> <!--[if lt IE 8]><link rel="stylesheet" href="blueprint/ie.css" type="text/css" media="screen, projection"><![endif]--> But I'm using DotLess and wish to simplify Blueprint as suggested here. So I'm doing this in my site.less (which gets compiled to site.min.css by Chirpy): @import "screen.css"; #header { #title { .span-10; .column; } } ... Now my site can just reference site.min.css and it includes blueprint's screen.css, which includes my reset. I can also tack on an @import "print.css" after my @import "screen.css" if desired. But now, I'm trying to figure out the best way to bring in the ie.css file to have Blueprint render correctly in IE6 & IE7. In my Spark setup, I have a partial called _Styles.spark that is brought into the Application.spark and is passed a view model that includes the filenames for all stylesheets to include (and an HtmlExtension to get the full path) and they're added using an "each" iterator. <link each="var styleSheet in Model.Styles" href="${Html.Stylesheet(styleSheet)}" rel="stylesheet" type="text/css" media="all"/> Should I simply put this below the above line in my _Styles.spark file? <!--[if lt IE 8]><link rel="stylesheet" href="${Html.Stylesheet("ie.css")}" type="text/css" media="screen, projection"><![endif]--> Will Spark even process it because it's surrounded by a comment?

  • iPhone contacts app styled indexed table view implementation

    - by KSH
    My Requirement: I have this straight forward requirement of listing names of people in alphabetical order in a Indexed table view with index titles being the starting letter of alphabets (additionally a search icon at the top and # to display misc values which start with a number and other special characters). What I have done so far: 1. I am using core data for storage and "last_name" is modelled as a String property in the Contacts entity 2.I am using a NSFetchedResultsController to display the sorted indexed table view. Issues accomplishing my requirement: 1. First up, I couldn't get the section index titles to be the first letter of alphabets. Dave's suggestion in the following post, helped me achieve the same: http://stackoverflow.com/questions/1112521/nsfetchedresultscontroller-with-sections-created-by-first-letter-of-a-string The only issue I encountered with Dave' suggestion is that I couldn't get the misc named grouped under "#" index. What I have tried: 1. I tried adding a custom compare method to NSString (category) to check how the comparison and section is made but that custom method doesn't get called when specified in the NSSortDescriptor selector. Here is some code: `@interface NSString (SortString) -(NSComparisonResult) customCompare: (NSString*) aStirng; @end @implementation NSString (SortString) -(NSComparisonResult) customCompare:(NSString *)aString { NSLog(@"Custom compare called to compare : %@ and %@",self,aString); return [self caseInsensitiveCompare:aString]; } @end` Code to fetch data: `NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"last_name" ascending:YES selector:@selector(customCompare:)] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"lastNameInitial" cacheName:@"MyCache"];` Can you let me know what I am missing and how the requirement can be accomplished ?

  • iPhone SDK: Switching to one view then back to previous view errors

    - by Nic Hubbard
    I have a UITabBarConroller that I use to switch between 3 different views. This all works perfectly. On one of my tabs, I added a button at the to called "Add", I have added an outlet to this, as well as an IBAction method which looks like the following: // Method used to load up view where we can add a new ride - (IBAction)showAddNewRideView { MyRidesViewController *controller = [[MyRidesViewController alloc] initWithNibName:@"AddNewRide" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentModalViewController:controller animated:YES]; [controller release]; }//end showAddNewRideView This currently works fine, and loads up my AddNewRide nib file. But, once that view loads, I have a cancel button, which, when clicked, I want to return to the previous view. So, I figured I would just do the reverse of the above, using the following method which would load back my previous nib: - (IBAction)cancelAddingNewRide { MyRidesViewController *controller = [[MyRidesViewController alloc] initWithNibName:@"MainWindow" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentModalViewController:controller animated:YES]; [controller release]; }//end cancelAddingNewRide But, which trying to load the MainWindow nib, the program crashes, and I get the following error: 2010-05-05 20:24:37.211 Ride[6032:207] *** -[MyRidesViewController cancelAddingNewRide]: unrecognized selector sent to instance 0x501e450 2010-05-05 20:24:37.213 Ride[6032:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[MyRidesViewController cancelAddingNewRide]: unrecognized selector sent to instance 0x501e450' So, I am a little lost as to why it would work one way, but not the other.

  • Creating a [materialised]view from generic data in Oracle/Mysql

    - by Andrew White
    I have a generic datamodel with 3 tables CREATE TABLE Properties ( propertyId int(11) NOT NULL AUTO_INCREMENT, name varchar(80) NOT NULL ) CREATE TABLE Customers ( customerId int(11) NOT NULL AUTO_INCREMENT, customerName varchar(80) NOT NULL ) CREATE TABLE PropertyValues ( propertyId int(11) NOT NULL, customerId int(11) NOT NULL, value varchar(80) NOT NULL ) INSERT INTO Properties VALUES (1, 'Age'); INSERT INTO Properties VALUES (2, 'Weight'); INSERT INTO Customers VALUES (1, 'Bob'); INSERT INTO Customers VALUES (2, 'Tom'); INSERT INTO PropertyValues VALUES (1, 1, '34'); INSERT INTO PropertyValues VALUES (2, 1, '80KG'); INSERT INTO PropertyValues VALUES (1, 2, '24'); INSERT INTO PropertyValues VALUES (2, 2, '53KG'); What I would like to do is create a view that has as columns all the ROWS in Properties and has as rows the entries in Customers. The column values are populated from PropertyValues. e.g. customerId Age Weight 1 34 80KG 2 24 53KG I'm thinking I need a stored procedure to do this and perhaps a materialised view (the entries in the table "Properties" change rarely). Any tips?

  • Performance of VIEW vs. SQL statement

    - by Matt W.
    I have a query that goes something like the following: select <field list> from <table list> where <join conditions> and <condition list> and PrimaryKey in (select PrimaryKey from <table list> where <join list> and <condition list>) and PrimaryKey not in (select PrimaryKey from <table list> where <join list> and <condition list>) The sub-select queries both have multiple sub-select queries of their own that I'm not showing so as not to clutter the statement. One of the developers on my team thinks a view would be better. I disagree in that the SQL statement uses variables passed in by the program (based on the user's login Id). Are there any hard and fast rules on when a view should be used vs. using a SQL statement? What kind of performance gain issues are there in running SQL statements on their own against regular tables vs. against views. (Note that all the joins / where conditions are against indexed columns, so that shouldn't be an issue.) EDIT for clarification... Here's the query I'm working with: select obj_id from object where obj_id in( (select distinct(sec_id) from security where sec_type_id = 494 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) and sec_obj_id in ( select obj_id from object where obj_ot_id in (select of_ot_id from obj_form left outer join obj_type on ot_id = of_ot_id where ot_app_id = 87 and of_id in (select sec_obj_id from security where sec_type_id = 493 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) ) and of_usage_type_id = 131 ) ) ) ) or (obj_ot_id in (select of_ot_id from obj_form left outer join obj_type on ot_id = of_ot_id where ot_app_id = 87 and of_id in (select sec_obj_id from security where sec_type_id = 493 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) ) and of_usage_type_id = 131 ) and obj_id not in (select sec_obj_id from security where sec_type_id = 494) )

  • Magento: Attribute always returns default value in catalog view, works fine in product view

    - by colinodell
    I've created a new Yes/No attribute for products. I've extended the Product model to do some custom logic and the custom functions are working everywhere. When I initially tried getting the custom attribute value, I ran into some issue. Magento wasn't loading it for me, so calls to $product-getMyAttributeName() did nothing. In the product views, I got it working with this additional function: public function getAttrVal($attr_name) { return $this->getResource()->getAttribute($attr_name)->getFrontend()->getValue($this); } So that worked great when viewing a product on the frontend. It would fetch the assigned value if set, or the default if not. When I view any Category (grid of all products in that category), the same exact code is being executed. But my getAttrVal() function always returns the default value, even if I've explicitly set this value for my product. I can't, for the life of me, figure out why the attribute loads correctly in the Product view but the Category view always grabs the default value, despite running the same exact code. Any thoughts?

  • How to blend multiple normal maps?

    - by János Turánszki
    I want to achieve a distortion effect which distorts the full screen. For that I spawn a couple of images with normal maps. I render their normal map part on some camera facing quads onto a rendertarget which is cleared with the color (127,127,255,255). This color means that there is no distortion whatsoever. Then I want to render some images like this one onto it: If I draw one somewhere on the screen, then it looks correct because it blends in seamlessly with the background (which is the same color that appears on the edges of this image). If I draw another one on top of it then it will no longer be a seamless transition. For this I created a blendstate in directX 11 that keeps the maximum of two colors, so it is now a seamless transition, but this way, the colors lower than 127 (0.5f normalized) will not contribute. I am not making a simulation and the effect looks quite convincing and nice for a game, but in my spare time I am thinking how I could achieve a nicer or a more correct effect with a blend state, maybe averaging the colors somehow? I I did it with a shader, I would add the colors and then I would normalize them, but I need to combine arbitrary number of images onto a rendertarget. This is my blend state now which blends them seamlessly but not correctly: D3D11_BLEND_DESC bd; bd.RenderTarget[0].BlendEnable=true; bd.RenderTarget[0].SrcBlend = D3D11_BLEND_SRC_ALPHA; bd.RenderTarget[0].DestBlend = D3D11_BLEND_INV_SRC_ALPHA; bd.RenderTarget[0].BlendOp = D3D11_BLEND_OP_MAX; bd.RenderTarget[0].SrcBlendAlpha = D3D11_BLEND_ONE; bd.RenderTarget[0].DestBlendAlpha = D3D11_BLEND_ZERO; bd.RenderTarget[0].BlendOpAlpha = D3D11_BLEND_OP_MAX; bd.RenderTarget[0].RenderTargetWriteMask = 0x0f; Is there any way of improving upon this? (PS. I considered rendering each one with a separate shader incementally on top of each other but that would consume a lot of render targets which is unacceptable)
