Last year the Torque2D was open sourced under an MIT license by GarageGames.  Torque2D is a cross platform 2D game engine.  Originally it only targeted Windows, OSX and iOS.  Now fortunately support for Android, Web and Linux have been added with the release of version 3.0.

 

From the release notes, here is what’s new:

What’s New in 3.0


The following is a summary of the major changes and additions:


Android, Linux, and Web Support

The major focus of this release brings several additional platform publishing options for your game or application. T2D truly delivers on cross platform support, making it easy with one codebase to reach many different audiences on many different devices.

64-bit Applications

In addition to the standard 32-bit support we’ve always had, the engine can now compile as a native 64-bit application for platforms that support it.

Named Image Cells and Frames

Until now, image frames have always been referenced using a numerical index. Now, developers have the opportunity to give explicit ImageAsset cells specific names. Those names can then be used with all SceneObject derived classes that consume ImageAssets.

<ImageAsset 

  1.     AssetName="soldierWalk"
  2.     ImageFile="@assetFile=soldierWalk.png">   
  3.     <ImageAsset.Cells> 
  4.         <Cell RegionName="walk1" Offset="2 2" Width="103" Height="66"/> 
  5.         <Cell RegionName="walk2" Offset="179 100" Width="37" Height="35"/> 
  6.         <Cell RegionName="walk3" Offset="2 70" Width="65" Height="31"/> 
  7.         <Cell RegionName="walk4" Offset="161 137" Width="36" Height="41"/>         
  8.     </ImageAsset.Cells> 
  9. </ImageAsset> 
  10. <AnimationAsset 
  11.     AssetName="soldierWalkAnim"
  12.     Image="@asset=ToyAssets:soldierWalk 
  13.     NamedAnimationFrames="walk1 walk2 walk3 walk4"
  14.     AnimationTime="1" /> 

Skeletal Animation

We are pleased to announce that an initial implementation for skeletal animation is now available. The first format supported comes from the animation program Spine.

Leap Motion Controller

The Leap Motion controller takes input from hands, fingers, and small tools that are moved just above its surface and provides their absolute position and rotation through the Leap SDK. Torque 2D offers built in integration and now includes a demo toy to show off how it works.

Xbox 360 Controller

Gamepad support has always been part of the engine, but now the necessary code to use an Xbox 360 controller with T2D has been added.

JSON Format for TAML

Joining XML and binary, developers can how serialize their game objects and scenes in the JSON format, with the engine being able to read-in or write-out this format as easily as the others.

 

  1. "Sprite": { 
  2. "SceneLayer": "31", 
  3. "Size": "100 75", 
  4. "BodyType": "Static", 
  5. "BlendColor": "SlateGray", 
  6. "Image": "@asset=ToyAssets:highlightBackground", 
  7. "Frame": "0"
  8.     } 

ConsoleMethodWithDocs

A major undertaking in the codebase, the vast majority of TorqueScript binding methods and global functions have moved into their own header files. This makes the engine code much easier to read and allowed us to further integrate Doxygen support for a comprehensive reference guide available in the wiki.

ScriptObject Behaviors

Behavior support was added to the ScriptObject class. If you enjoy writing behaviors, now there is an engine class outside of the Scene and SceneObjects which can use them.

Polar Coordinate Changes

One of the few changes made that would break any of your existing scripts - polar coordinates have been standardized throughout the engine to follow the typical polar axis convention where 0 degrees is horizontal and to the right.

New Sandbox Toys

A few more toys were added to the Sandbox, giving new users even more practical examples to learn from. These include AudioToy, AngleToy, LeapToy, and SpineToy.

Torque2D is available on Github.

 

I’ve personally never checked out Torque2D, one of the biggest drawbacks was the limited platform support, which has been solved by this release.  My other major caveat is their use of a proprietary scripting language, something I am generally not a fan off.
