Hi

I am using spine with libgdx. And having a weird issue.
Basically as it is mentioned here: http://esotericsoftware.com/spine-loading-skeleton-data

There are 2 ways to scale animation, for our purposes it makes sense to use the second method which is finding root bone on skeleton data and scaling it. Weird thing is, when this is done, the order of animation messes up, as in things happen out of order. If I scale SkeletonJson instead, everything is fine. (But that will mess up positioning so can't use that).

I am linking a sample project to show the issue in action.
http://kiki-fish.com/uploads/scale_issue.zip

It has the spine project, libgdx project, (and spine runtimes in same folder for thing to work out of the box). This also contains JAR to visualize the problem (on the top the crack animation is as it should be, and on the bottom it's wrong, and all difference is in the method it is being scaled)

We spent like 2 days on this, and most probably doing something wrong.. but deadlines are coming, and any help is much appreciated!

Best.

Just tested same thing IN the editor, and it seems this is not runtime related, because if I scale root bone in the editor it has same effect. That is weird. So it has to do with the way animation is rigged. But I have no idea what's wrong. Should I still put it in tracker?

It's like as if "constraint scale" is not being affected by the root bone scale.

UPD: Also, when we try to change constraint scale now manually in the editor (the new version) it just freezes. (when the root bone is scaled. It is reproducable every time)

UPD2: So I did some digging, and made a video to show exactly what's going on, as you can see animation works just fine, but when root bone is scaled, it somehow makes all bones clamp up in single spots, reason being, scale of each bone is affected in such a way, that it's 0. When I click on a bone that is affected, it shows as 0 scale for X, and you can see that at some point it swaps to become "1" without me typing it, I just clicked. And then it goes back to 0 if clicked again. Due to this problem you can see how animation looks all wrong. because most of it is scaled into single 0 scale points. And all I did was to scale root bone to 0.3

Here is the video:

Thanks for getting back Nate! really appreciate it.

I'll try to see if changing to Percent will fix it, and get back to you!

As for the freezing, here is how to reproduce.
Open the project, and in setup mode select root bone and change it's scale to 0.3, 0.3, then click on "setup" to enter the animation mode. select a path constraint (seems does not matter which one) then change the scale value on it. click somewhere on empty canvas, things get frozen and not responsive anymore.

As to why we did use length instead of percent (according to our animator), when you select percent, the "scroll" bar near it, is kind of "shaky and jumps in a weird way" so that it's not very convenient to use.

UPD: using percents did help! And also pulling the changes from 3.5 can be good idea for our other old animations. So we'll check that as well. Huge thanks!
