Unwanted behavior from FlipX with skeleton utility.

Owe

Hello!

Unity (5.4.2f2)
Unity Spine Runtimes (Last updated: UTC - 2016 November 19)
Spine(3.5.27 Pro)

We recently upgraded to the new runtimes and Spine, but I can't get the FlipX property to behave with Skeleton Utility (Spawned Hierarchy): The skeleton gets flipped upside down or something similar to that effect. I then took a look at the SkeletonUtility Animated Physics example and it seemed to have the same problem:

A bit secondary; but I then checked the Basic Platformer example to see if that was wrong as well, but to my surprise that works, but used flipping by having a GameObject with all the graphics turn 180 degrees:

I can't remember, but I was under the impression that this is not a good way to handle flipping? I am certainly confused and would appreciate any help I could get.

I have a similar problem here.

The bones of the Barnacle are on the correct position:

But when I flip the parent object, the SkeletonUtilityBones moves to another wrong position:

This causes me a problem calculating distances based on the bones position.

Pharan

That's odd. We'll take a look. Are the animations still moving correctly?

Regarding 180º rotation for flipping:
It's fine with 3D physics. (And the basic platformer example uses a classic Unity Character Controller which is 3D)
You get unpredictable results with 2D physics.
Whichever way you choose, you just need to be aware of the effects. For example, if you don't use the right shader, rotating will cause normals to point the wrong direction.

Yes, the animations seem to move correctly.

Thanks for clearing up about rotational flipping.

Mine too, animations are not the problem but bones position.

Can confirm that there are some definite problems with flipX and exposed skeletons via SkeletonUtility.

Any updates on this? Flipping / Negative Scaling doesn't seem to work at all right now (with SkeletonUtility, exposed Bone Hierarchy)

Ookayy..sorry to be a bother, but this issue is seriously impacting our work right now, many of our assets are not functioning correctly due to the flipX or flipY messing up.
Is there any ETA on a fix? Is it a serious problem with the runtime or a lightweight bug?

Pharan

It's hard to tell currently. We'll have more to share tomorrow.

Basic flipping should be fixed now but kinematic shadow hinge chain (shown in the raptor example) is a more complicated fix. No ETA for that right now.

Hi Pharan,

I just tried the newest runtimes but they broke SO MANY things in my game I had to revert the update. The only thing that seemed to work was, indeed, the flipX /flipY bug 😃

Can you maybe tell me where exactly the fix for that was? I am going to have to manually patch that into my runtime as I can't use the newest runtimes anymore.

kbm, you moved from 3.4 to 3.5? Or from 3.5 to the latest 3.5? If the latter, I'd like to know what broke. Was it the trackEnd change?

I was already on 3.5 but I manually hacked the AnimationState.cs to always set setupPose to false (as you suggested in another thread). I just tried out the newest Runtimes and I'm not 100% sure what exactly was the problem, only that almost all animations stopped working correctly, which never happened before..seemed very strange and I almost immediately reset my project after nothing really worked.
Sorry, can't really tell you more :/

Anyways, I just swore to myself to stop updating spine & runtimes for THIS project because too many things broke after 3.5 and some are still broken (like the flipX / flipY stuff)..

So if you could just point me in the right direction on how to manually fix that, I'll show myself out after that and won't return until I discover the next dealbreaking bug :party:

Update: I updated JUST the spine-unity runtime (newest one) and this made everything so far work correctly, I think the stuff that breaks my game is mostly the newest changes to AnimationState etc.

Can you start a new topic describing how AnimationState breaks your setup? That's different from this topic.
