Force Engine 2 is an old (from 2007) physics engine written in Java with some game engine components. It is primarily a learning and research project focused on testing ideas around collision detection and response, as well as fluid dynamics.
There are also tutorials, presentations, and research papers explaining the circle-circle and circle-line collision detection and response algorithms.
Force Engine
depends on Java 6. Force Engine Android
requires the Android SDK.
The easiest way to get the Java demo running is by opening the Force Engine
project with Eclipse and running ForceEngineDemo
.
To open the Android app, open Force Engine Android
with Android Studio.
The library can be exported from Eclipse using the physics.jardesc
file in the Force Engine
project. The .jar
file produced is then used in Force Engine Android/app/libs
.
Create a new instance of the physics engine with
PhysicsEngine engine = new PhysicsEngine(<width>, <height>);
Inside a thread, advance to the next tick with engine.components()
.
