How to do it...
You can handle jumping animations by performing the following steps:
1. For this, we'll need to add two more Booleans to our animation control:
jumpStarted
and
inAir
.
2. We trigger the first part of the animation in the
onAction
method, as shown in
the following code. The
jumpStarted
Boolean is used to let the class know that
other animations should not start while the character is the jumping state:
public void onAction(String binding, boolean value,
float tpf) {
if (binding.equals("Jump") && value) {
jumpStarted = true;
setAnimation(Animation.JumpStart);
}
}
3. The
onAnimCycleDone
method should switch animations back to the jumping
action once
JumpStart
has finished playing. We also set
inAir
to
true
, as
shown in the following code:
public void onAnimCycleDone(AnimControl control,
AnimChannel channel, String animName) {
if(channel.getLoopMode() == LoopMode.DontLoop){
Animation newAnim = Animation.Idle;
Animation anim = Animation.valueOf(animName);
switch(anim){
case JumpStart:
newAnim = Animation.Jumping;
inAir = true;
break;
}
setAnimation(newAnim, channel);
}
}
4. The
controlUpdate
method is suitable to check whether the character has
landed after jumping (or falling). We check this directly in
