Mastering Character Animations - jMonkeyEngine 3.0 - page 191

How it works…
The AnimControl class is responsible for playing and keeping track of the animations.
AnimChannel has a list of Bones that the animation should affect.
Since we let the enum decide the animation parameters for us, we don't need much code in
the setAnimation method. We do however need to make sure we don't set the same an-
imation if it is already playing or it could get stuck, repeating the first frame in a loop.
The onAnimCycleDone method is called from AnimControl whenever an animation
reaches the end. Here, we decide what will happen when this occurs. If the animation is not
looping, we must tell it what to do next. Playing the idle animation is a good choice.
We also have one special case. If you look at the animation list, you will notice that Jaime's
jump animation is split into three parts. This is to make it easier to handle jumps of differ-
ent lengths or the falling animation.
We will tell AnimControl to change the animation to a jumping action once
JumpStart is done. We never change to JumpEnd once the jumping action has taken
place however. Instead, this should be called from elsewhere when Jaime hits the ground
after he jumps. How this is measured is dependent on the game logic, but since we're using
the Control pattern, we could use controlUpdate to check Jaime's whereabouts.
