  • Slot SetColor Not working properly for some users

Hello we are making a game with a color selector. It works for most users and doesn't work for others. We are in open beta so we have been trying to narrow down why only some people cannot change slot colors? They get bright green characters or invisible-ish characters.

Code:
Spine.Slot mySlot = skeletonAnimation.skeleton.FindSlot("Beard");
mySlot.SetColor(color);

Example of a player getting the bug:

Example of a normal player without the bug:

Is there a Unity setting to help or something I'm doing wrong? Any ideas would be appreciated it's a major part of our game and I've been fresh out of ideas.

As you say bright green: should the green skin tone be darker?
At the starting time of the video URL (15s) it shows a transparent green upper body and arms: do you have any alpha values other than 1 in your selectable colors?

If all selectable colors have an alpha of 1: Did you perhaps use blend modes like Additive, Multiply or Screen? You could check whether there are perhaps some BlendModeMaterialAssets present at some of your characters, especially the one where the bug occurs. For that please have a look if there are any set at the Skeleton Data Modifiers property of the SkeletonDataAsset.

Please also check the Spine project whether there are any of the Slots perhaps set to Add, Multiply or Screen instead of Normal. In general, please check the Spine project of the female character where the bug occured in the video.

If these are all setup correctly, please check whether perhaps the Spine Editor version and the version of the spine-unity runtime are different, leading to mis-interpreted data upon import (which is rather improbable however).

Just my 2 cents, and you may have already looked into this (I think it was mentioned in that other thread about coloring), but the first thing I usually check when something works on one computer but not another is the Script Execution Order.

I've ran into several issues where the SEO happened to be correct in the Editor (by chance, without the scripts in question actually being added to the SEO list), but in the build it didn't work properly. Was tough to track down.

BTW I saw Iain Garner posting about your beta on Twitter a couple days ago! Your game looks awesome, I invited a couple of my friends that are big into card games. Some really great usage of Spine in there!

Things to double check. See if you haven't keyed color as the first or last frame.

Thank you guys for the helpful comments - I am finally circling back to this as it was not the highest priority bug at the time.

I'm really hopeful these tips can help me get it sorted :-)

I'll tell Iain you have said hello!

I don't understand this one - can you elaborate?

I actually believe this is a contender for what's going on but it will be difficult to find and diagnose since i can't repeat the error myself. I hope to find a computer with the bug but i currently don't have one. its 1/20 people that actually have this. Gamer PC's usually and both my fastest ones don't do it.

Here's a list of the machines w the problem so far trying to find patterns.

Confirmed now - that in a scene, totally devoid of objects except color buttons and a Spine character, the SetColor works fine. So basically Spine is working fine but something in our main gameplay scene is causing it to malfunction for certain people (seemingly with fast computers)

So i think there's some execution order thing going on indeed. It's still stuck but I thought I'd clear Spine of the issue at least because its definitely specific to our game scene somehow.

Maybe it is already ruled out, but it could be a matter of animation timing. You could try to click the same character and color-buttons at the same times of the animation as in the videos that show the problem.

It means to check all of the animations that are played in the Spine Editor whether there are any keys that set color RGB or alpha values. Like bone rotation and translation keys you can also set keys for color changes, which would explain you issue.

You could send us a skeleton .json file (re-exported as json as it's better human-readable than the binary .skel.bytes file) of the character, there we can quickly see if any color keys are present. You can attach it to a posting in this thread or send it to contact@esotericsoftware.com (with a reference URL to this thread) if you would like to keep it confidential.
