[AnimationState] Some problem with mixing out not in order.

[pharan]

This totalAlpha condition seems to be preventing an ended TrackEntry (mixTime > mixDuration) from actually being ended.

spine-runtimes/spine-libgdx/spine-libgdx/src/com/esotericsoftware/spine/AnimationState.java

Lines 147 to 151 in 34086c1

	if (from.totalAlpha == 0) {
	to.mixingFrom = from.mixingFrom;
	to.interruptAlpha = from.interruptAlpha;
	queue.end(from);
	}

With this condition in place, it seems to present the problem linked below. Commenting it out removes it.

The bug may also be related to this:

spine-runtimes/spine-libgdx/spine-libgdx/src/com/esotericsoftware/spine/AnimationState.java

Lines 222 to 223 in 34086c1

	if (to.mixDuration == 0) // Single frame mix to undo mixingFrom changes.
	mix = 1;

As the code passes through this branch several times instead of only once, because the TrackEntry doesn't end.

@pharan How can I see this with the ref impl? I tried:

state.getData().setMix("stand", "move", 0.3f);
state.setAnimation(0, "move", true);
state.addAnimation(0, "stand", true, 2);
state.addAnimation(0, "attack_1", false, 2);
state.addAnimation(0, "move", true, 2);
state.addAnimation(0, "stand", true, 0.81f);
state.addAnimation(0, "attack_1", false, 0.2f);

I don't see meshes that aren't reset to the setup pose, though I don't really know what I'm looking for. I also tried using setAnimation with sleeps between them.

@NathanSweet I actually ran into the same problem.

vzlomvl mistyped.

state.getData().setMix("move", "stand", 0.3f); // should be move-stand. not stand-move as vzlomvl posted.
state.setAnimation(0, "move", true);
state.addAnimation(0, "stand", true, 0.81f);
state.addAnimation(0, "attack_1", false, 0.2f); // look at her left pant leg.

That should repro it.
The first three animations just demonstrate a case where it isn't broken.

Ah, thanks @pharan! I think I have a good fix.
