I have this code for the onAnimCycleDone method which is also in a control :
@Override
public void onAnimCycleDone(AnimControl control, AnimChannel channel, String animName) {
Animations anim = Animations.looseValueOf(animName);
switch (anim) {
case ATTACK:
case HURT:
channel.reset(false);
}
}
I have three animation channels. One for each of the following animations : hurt, idle and attack. Yes I know that I should use channels with bones in mind instead of animations in mind. However, I have a setup, more specifically an insertion sort that sorts the channels in the AnimControl so that the most prioritary channels are at the beginning of the list. It works atually.
My problem is that calling reset will then result in an nullptr exception in the channel’s update method.
void update(float tpf, TempVars vars) {
if (animation == null)
return;
if (blendFrom != null && blendAmount != 1.0f){
// The blendFrom anim is set, the actual animation
// playing will be set
// blendFrom.setTime(timeBlendFrom, 1f, control, this, vars);
blendFrom.setTime(timeBlendFrom, 1f - blendAmount, control, this, vars);
timeBlendFrom += tpf * speedBlendFrom;
timeBlendFrom = AnimationUtils.clampWrapTime(timeBlendFrom,
blendFrom.getLength(),
loopModeBlendFrom);
if (timeBlendFrom < 0){
timeBlendFrom = -timeBlendFrom;
speedBlendFrom = -speedBlendFrom;
}
blendAmount += tpf * blendRate;
if (blendAmount > 1f){
blendAmount = 1f;
blendFrom = null;
}
}
animation.setTime(time, blendAmount, control, this, vars);
time += tpf * speed;
if (animation.getLength() > 0){
if (!notified && (time >= animation.getLength() || time < 0)) {
if (loopMode == LoopMode.DontLoop) {
// Note that this flag has to be set before calling the notify
// since the notify may start a new animation and then unset
// the flag.
notified = true;
}
control.notifyAnimCycleDone(this, animation.getName());
}
}
// HERE IS THE BUG! ANIMATION == NULL
time = AnimationUtils.clampWrapTime(time, animation.getLength(), loopMode);
if (time < 0){
// Negative time indicates that speed should be inverted
// (for cycle loop mode only)
time = -time;
speed = -speed;
}
}
At the line
time = AnimationUtils.clampWrapTime(time, animation.getLength(), loopMode);
animation is null even though there was a check at the beginning of the method. Does that mean I have a multithreading problem here? How can I set the animation to null (I am debugging something and I need to the animation to null)?
