4.3.39 pro, "sometimes" transform constraint, x and y get reversed

Problem statement

Describe: 1) what you have tried, 2) what you expected, and 3) what actually happened.

I'm following the udemy course https://www.udemy.com/course/spine-pro-a-complete-2d-character-animation-guide/learn/lecture/20671508#questions/11838780

I tried to do it using 4.3.39beta pro , but at several moment (not always) when i tried to create a constraint, the x and y was reversed , i.e even though I linked X to X and Y to Y , when moving on the X axis the source , the target was moving on the Y axis, and reversely , moving on Y axis was moving the source on X axis

I tried to export and reimport the skeleton in json format, but still same issue. I'm on linux.

Give step-by-step instructions so we can reproduce the problem, if possible.

Editor information

Tell us your Spine Editor version.
4.3.39

I got not error message

I can provide the .spine file , but I don't know where to attach it

I'm sorry to hear you're experiencing issues with transform constraints in the beta version. Based on my knowledge, there have been some bugs related to transform constraints in recent beta versions that have since been fixed.

Recommended Solutions:

Try version 4.3.36-beta: There were known issues with version 4.3.39-beta related to transform constraints. Version 4.3.36-beta was more stable. You can switch to this version by:
- Going to Spine's settings and changing the version
- Or deleting the version.txt file located at ~/.spine/version.txt on Linux, then manually specifying the version
- Or running Spine from the command line with: Spine.sh --update 4.3.36
Check constraint settings: When setting up transform constraints, make sure:
- The mix values are set for both X and Y axes (not just X)
- The constraint order is correct, as other constraints can interfere if applied in the wrong sequence
Send your project file: If the issue persists, you can send your .spine project file (images are not necessary) to contact@esotericsoftware.com so the team can investigate the specific issue you're encountering.

Note about beta versions: During the beta period, there can be cases where bugs exist that haven't been caught up with yet. The development team fixes these issues quickly, often within days, especially when users provide reproduction steps.

Since you're following a course, using version 4.3.36-beta might be your best option to continue being productive while any remaining issues in 4.3.39-beta are resolved.

Spinebot thanks mister bot, currently i've downgraded to version 4.2 , for 4.3.39 the bug was there wether

I set both x to x and y to y
Or only x to x
or only y to y

do you still need I send the project file ?

ok sorry, it seems the issue was that the target bone was not correctly set in the hierarchy

Keep an eye on which coordinate system you are considering. Local X and Y can point in different world directions depending how the parent bones are transformed.
