Most interesting is ability to build C++ Oxygine application for Web via Emscripten. So you write C++ code and it will compile it to HTML5/JS.
Specs
Question Ranking
Pros
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.
Pro Games can be built as HTML5 applications
Most interesting is ability to build C++ Oxygine application for Web via Emscripten. So you write C++ code and it will compile it to HTML5/JS.
Pro Functionality can be extended with a bunch of available extenions
All of them available publicly at github.
- oxygine-movie for playing Theora movies with alpha channel
- oxygine-sound player for ogg sound/music with streaming
- oxygine-freetype library
- oxygine-billing for in-app-purchases on Android/iOS
- oxygine-spine for playing Spine animations
- oxygine-magicparticles for playing particles made with MagicParticles
Pro Will be familiar to users of ActionScript3/Flash API
If you are familiar with ActionScript3/Flash API, then you will find it easy to begin working in Oxygine. Oxygine is much like Flash in C++, as its Event Handling model is very close to that of ActionScript 3 and SceneGraph.
Pro Easy to use C++ API with optional C++11 features
Oxygine is written in C++. It provides easy to use API, which is designed with "do more with less code" philosophy. It uses a managed scenegraph system that takes care of rendering and updates, and provides ability to extend with custom rendering and updates.
Pro Free, open source and cross-platform
Oxygine is a free framework that works on OS X, Windows, Linux, iOS, Android, HTML5. It's licensed under MIT with source code available on GitHub.
Pro Robust
It's very rare to experience bugs with Oxygine.
Pro Allows playing movies with alpha channel
Using oxygine-movie extension for Oxygine you could play in your game any videos encoded with Theora codec.
You movie could have alpha channel and used as simple sprite instead of classic spreadsheet animations.
Pro Allows for flexible contol over draw processes
Pro Fast
Cons
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.
Con Inactive
The project does not seem to be active: there has been no new commit since mid-2019, the Twitter feed for the engine stopped posting news in 2018, and the forum is offline as of May 2021.
Con Little community support
Oxygine is a young framework. It was first released in 2013 and has yet to gather a large community. As of February 2016, the forum had just 123 members.
Con Not many tutorials available
There are not many tutorials available that teach developers on how to make a game with Oxygine from scratch. Because of this, it may be harder to pick it up or to start learning game development by using this engine.
