Ranked in these QuestionsQuestion Ranking
Pros
Pro Extremely extendable and customizable
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.
Pro Cross platform
Torque 2D runs on Windows, OS X, iOS, Android, Linux, and Web.
Pro The scripting language is quite powerful
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
Pro Highly performant
The engine utilizes a combination of batched rendering, asset management, and a module system that allows for high frame rates on all platforms.
Pro Box2D physics
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.
Pro Extensive documentation available to support development
ImpactJS has an active user community that busily produces tremendous resources including videos, books, tutorials, walkthroughs and more. There are also comprehensive class documentation available.
Pro Excellent collision detection system
Impact provides 2 types of collision detection; static and dynamic collisions. Both of which are easily integrated into game development.
Pro Extendable
Many plugins are available, including one called Impact++ which adds features like pathfinding and dynamic lighting.
Pro Level editor
Built-in map editor with support for tiling, collision layers, and actors.
Pro Optimized
Works with Box2d physics library, comes with all worthwhile elements for actors built in.
Pro Truly cross-platform allowing developers to build for anything
Extending the reach of a game developed with ImpactJS is easy due to the cross-platform nature the framework. There are Considerations around performance, resolution and audio, however all can be appropriately addressed when in development. Works in the browser via Canvas, even on mobile. Easily translatable into a packaged app.
Cons
Con Project seems to be abandoned
Seems to not be developed/supported anymore.
Con Lacking documentation
The engine documentation is incomplete. Not all of the engine API is fleshed out and the number of tutorials is pretty small. All current and future documentation effort is up to the community, via the Torque 2D MIT GitHub wiki.
Con Rentware
Con Inactive
The last update was in 2014.
Con Cost of $99
While most HTML5 frameworks are offered as free open source projects, ImpactJS has a one time cost and no free option.
