Run-time generated AnimationClips leaking
I currently create AnimationClips dynamically while my game is running to move some pieces around. You can see what I mean here: https://youtu.be/u1My9JX4K-c?t=8s , when the pieces get grouped together and then open again. I cannot reuse the clip because the pieces will have a different position next time, so all the movements need to be changed.
Right now, I create a new clip whenever I need them to be grouped and separated, and attempt to replace any existing clip with this:
private void ReplaceAndPlay(AnimationClip clip, string name) {
var old = Anim.GetClip(name);
if (old != null) {
Anim.RemoveClip(name);
Destroy(old);
}
Anim.AddClip(clip, name);
Anim.Play(name);
}
(Anim just points to the gameObject's Animation component)
But using the profiler, I see that the animation clips just keep accumulating, they don't seem to be garbage collected. Am I missing something or doing something wrong? Can they be garbage collected?
Hmm, that's strange. I never had a case where i needed to constantly creating new clips. However since you properly destroy the old clip it should work i guess. However maybe the RemoveClip method doesn't do it's job correctly and there might be a reference to the "managed corpse" of the old clip somewhere.
Anyways i don't quite get why you can't reuse the old clip. You can call ClearCurves on the old one and add the new curve data.
I ended up following @Bunny83 suggestion, reusing the animation with ClearCurves. Not exactly what I wanted, but it works and does not leak.
