3D demo game built with libGDX

GdxDemo3D

GdxDemo3D is a game project built with libGDX, demonstrating various aspects of the game library, as well as its extensions, such as the physics engine Bullet wrapper and the artificial intelligence library gdx-ai.

A simple 3D world is included, with a multi storey house and various other items.

Animated human and dog characters are used as actors in the world. Ragdoll physics allows for dynamic character animation when a human falls down.

The gdx-ai pathfinding module in conjunction with a navigation mesh handles pathfinding, the gdx-ai steering behaviors module handles character movement while state machines and behavior trees are used to model human and dog brains respectively.

The Bullet physics library is used to handle collisions and forces between objects.

Objects in the world can be modified directly in Blender and exported into the game with an automated script.

gdxdemo3d's Issues

Minor issue: drawArmature does not take into account character's orientation

MotionState disposed twice

See bfa71b9#commitcomment-15913781

Issue with the stick

If the stick is on the ground when the man whistles then the dog should first pick it up.

NoSuchMethodError

Hello jsjolund,
I'm running into this problem "java.lang.NoSuchMethodError: com.badlogic.gdx.scenes.scene2d.Actor.getListeners()Lcom/badlogic/gdx/utils/Array;"

Can you point me in the right direction of how to fix this step by step? I just need a starting point.
Where in Android Studio I should add --verbose:class when running the app? I'm a newbie. Everywhere online says just add this code, that code, but where should it be added in the system? I can't seem to find it. The official Android website is no help. Thanks
