使用SkeletonMecanim时spine event相关问题
fengmin Unfortunately, I'm not sure why the crashes occur, but I think Harald will answer that later.
Anyway, I think there are some solutions. For example, you can modify the code to register a handler for the End event of the TrackEntry and call AddEmptyAnimation() beforehand so that the animation returns to the setup pose when it is complete.
Spine.TrackEntry trackEntry = attackAnimator.SetAnimation(0, "attack", false);
trackEntry.End += AttckAnimalComplete;
animationState.AddEmptyAnimation(0, 0, 0);This way, the End event is fired when the animation switches to the empty animation, so it is sufficient to simply register a method to the End event. This allows you to cover both the case where the animation is complete, and the case where the animation is switched to another before it is complete.
fengmin Oh, sorry, I forgot to add that I assumed that the AttckAnimalComplete() would be like this:
void AttckAnimalComplete(Spine.TrackEntry trackEntry) {
isAttk = false;
isAttked = true;
playerState.playerState = CharacterState.Idle;
attackAnimator.state.SetEmptyAnimation(0, 0);
}Please note that ClearTracks() does not reset the pose of the previous animation. This is explained in the API reference: https://esotericsoftware.com/spine-api-reference#AnimationState-clearTracks
So you should use SetEmptyAnimation() instead of ClearTracks().
Misaki After trying this, Unity froze even if I just called SetEmptyAnimation() on both the Complete and End events, so it seems that the problem is not ClearTracks(), but that you are trying to do these operations on both Complete and End.
@fengmin Note that SetEmptyAnimation() or SetAnimation() in general is also triggering End and Complete callbacks. You're creating an infinite loop if you call SetEmptyAnimation() or SetAnimation() from a callback of AnimationState.End or Complete. You need to either register to callbacks of a single TrackEntry like trackEntry.End += YourCallback or use AddEmptyAnimation() as Misaki mentioned above.
Harald 所以是因为在“attack”动画End或Complete时，SetEmptyAnimation()的这个EmptyAnimation本身也会带有End 和 Complete回调并且被瞬间执行，导致了无限循环，那么同理这里使用AddEmptyAnimation()是否也会无限循环，EmptyAnimation的名称是什么，我可以通过在开头进行非空判断来避免循环吗，例如
private void AttckAnimalComplete(TrackEntry trackEntry)
{
if(trackEntry.Animation.Name.Equals(""))
return
isAttk = false;
SetEmptyAnimation();
}
@fengmin You can use trackEntry.IsEmptyAnimation.

In general as Misaki pointed out already, it would be far more recommended to call AddEmptyAnimation() directly after setting e.g. the attack animation.
Also, it would likely be better to call attackTrackEntry.Complete += AttckAnimalComplete instead of registering it at animationState.Complete += AttckAnimalComplete, as you then receive the callback with every completed animation and not only your attack animation.
Misaki 最后我想问一下我该在什么地方注销我的complete事件注册,下面的例子正确吗
Spine.TrackEntry trackEntry = attackAnimator.SetAnimation(0, "attack", false);
trackEntry.Complete+= AttckAnimalComplete;
animationState.AddEmptyAnimation(0, 0, 0);
void AttckAnimalComplete(TrackEntry trackEntry)
{
isAttck = false;
trackEntry.Complete -= AttckAnimalComplete;
}
