Jenkins build status (Jenkins)

An artificial intelligence framework, entirely written in Java, for game development with libGDX.

The gdxAI project is a libGDX extension living under the libGDX umbrella. However it does not force you to use that specific framework if you do not wish to do so. The libGDX jar remains an essential requirement, mostly due to the use of libGDX collections which are optimized for mobile platforms by limiting garbage creation and supporting primitive types directly, so avoiding boxing and unboxing.

GdxAI tries to be a high-performance framework providing some of the most common AI techniques used by game industry. However, in the present state of the art, the gdxAI framework covers only part of the entire game AI area, which is really huge. We've tried to focus on what matters most in game AI development, though. And more stuff will come soon.

Currently supported features are:

  • Movement AI
    • Steering Behaviors
    • Formation Motion
  • Pathfinding
    • A*
    • Hierarchical Pathfinding
    • Path Smoothing
    • Interruptible Pathfinding
  • Decision Making
    • State Machine
    • Behavior Trees
  • Infrastructure
    • Message Handling
    • Scheduling
