jMonkeyEngine Animation State Machine

State machine to make animation states consume from a character controller state. This way Character controllers no longer need to think about animations. This Anim State Machine works with two entities, states and links.

State

Create a state in default layer with name "idleBase", and set it as the default state.

ActionState idleBaseState = animStateMachine.addState(
    "idleBase", 
    new ClipAction(animComposer.getAnimClip("IdleBase"))
);
animStateMachine.setDefaultState(idleBaseState);

Links between states can not cross a layer. State in different layer "top" (assumes this layer exists in the AnimationComposer).

ActionState idleTopState = animStateMachine.addState(
    "idle",
    "top", 
    new ClipAction(animComposer.getAnimClip("IdleTop"))
);

Link

Creat links between states, and specify when the state should move to the next state

Link idleToRunning = animStateMachine.addLink(idleBaseState, runningState);
idleToRunning.when(() -> getForwardVelocity.get() >= 0.01f);

Link Delayed Condition

You can set a conditional link between two actions on the end of the former action.

OnFinishedEventAction onFinishSomeAction = new OnFinishedEventAction(animComposer.getAnimClip("SomeAction"));
doSomethingElse.when(new DelayedConsumer(onFinishSomeAction));
