[Unity] Event not fired during animation mix

Snazzlebot

Hi, I'm getting a problem where defined events are not firing when placed within the last 5 frames of an animation.

This only happens if I'm mixing to another animation via 'AddAnimation'.
If I use 'SetAnimation' after the previous animation completes, then it fires correctly in the final frames, but then I lose the nice blend.

So it seems any events defined within mixed frames are ignored, is this correct? If so, is that a bug that could be fixed?

Thanks!

How long was the mix? (just for more info to look into it)

I'm thinking the code that handles it is somewhere here: https://github.com/EsotericSoftware/spi ... te.cs#L114

Line 116 is particularly suspicious:

previous.animation.Apply(skeleton, previousTime, previousTime, previous.loop, null);

I think I kinda see where the problem is but we need to trace back how previous is updated.

[EDIT]

Try to find AnimationState.cs in your Unity project and replace it with this attached file.
The first question still stands though, how long was the mix?

Thanks Pharan, I gave that a try but it didn't seem to work I'm afraid. I didn't set the mix to any specific value, so I'm assuming it's using some default?
I'm just adding the second animation with the regular stub - AddAnimation(int trackIndex, Animation animation, bool loop, float delay)
This seems to mix with some default value.

SkeletonDataAsset has that default mix value. Try setting it to zero.

I think I just made a careless mistake.
Try this one?

Doh, nope still no luck sorry Pharan. Mitch, I dropped the mix value to 0 and sure enough, the event will fire with no mix. It was set at 0.2.
I'll keep trying to figure it out. I really need that event fired in the last couple frames but along with the mixing.

Thanks for the help so far.

Mitch

I'll take a proper look at this when I get in. Thanks for spotting it - its definitely a c# issue and not isolated to unity.

Pharan

Hey. I got this. Get your own turf. XD
Actually, I found the problem. I didn't have a test setup before so I couldn't tell what was really going on.
I solved the first problem of the events not fitting into the time range. I just needed to bring it into the AnimationState class and fire it. I thought it would need a few extra lines but it turns out, I just needed to replace null with the existing events list. (turns out Nate was passing null, meaning he might have intended for events not to fire during a mix?)

And done. FOR SURE this time. I've seen it work with my own eyes.
Third time's the charm. The total number of lines changed/added since the first post were like... 3? 4?

The other thing I found is that if you're mixing, Complete doesn't fire on the first animation either. I'm actually not sure which behavior makes more sense; this or a firing one.

Made a PR though. Didn't try to fix Complete not firing.

Yay it's now working Pharan. Thanks so much for your help!
