Torque 2D MIT vs Duality

Torque 2D gives developers complete access to the source code. This removes all barriers one may hit when trying to extend and/or customize the engine they are working with.

Torque 2D runs on Windows, OS X, iOS, Android, Linux, and Web.

Torquescript is a fast and easy to use C++ like scripting language that ties all of the various elements of a project together. It supports a large complement of functions including math, physics, object manipulation, fileIO, and more. Torquescript features:

• Object-oriented programming
• Transparent interconnection with internal C++ objects
• Built-in fast 2D math (vectors, matrices, and quaternions with all corresponding functions)
• Well-documented standard library (hundreds of functions out-of-the box)
• Component system (aka Behaviors)
• Dynamic asset and module loading

The engine utilizes a combination of batched rendering, asset management, and a module system that allows for high frame rates on all platforms.

Torque 2D MIT's utilizes Box2D for all physics calculations. Anyone with prior knowledge with Box2D by itself or through other engines can easily transfer their knowledge. Nearly all of the Box2D API is exposed to the scripting language, making it a quick process to port games to the engine without having to learn an entirely new system.

The full source code is available on GitHub, where the framework is actively developed. All of the editor, core and plugin code is written in C#.

Duality includes a powerful visual editing system that can be used for previewing, integrating, editing and testing game content.

Because both Core and Editor are completely plugin-based, Duality not only incorporates a clean and modular design, but is also very extensible - even if it wasn't Open Source. In fact, most of the standard editing capabilities comes in form of Editor plugins.

It can be configured to serialize all data in a text-based format, which has been structurally optimized for version control systems.

It has been used in a production environment without burning the place to the ground. Supposedly artist-proof editor workflow with an API for tailoring the system to fit your team.
