Constructor Detail

AnimationPlayerManager

public AnimationPlayerManager(PhysicsCallback pb,
                              VJoint animationRoot,
                              VJoint currRoot)

ASSUMPTION: the humanoidroots are added directly under animationRoot In each frame: 1. Run all animation players, in each animation player:
a Copy next to cur, cur to prev
b Run procedural animations on next
c Calculate the forces and torques generated by the proc motion
2. Do a physics step
3. Copy physical body rotations to cur and next
4. Copy curr to the animation tree

time

public void time(double currentTime)

getH

public static float getH()

Returns:
