IL2CPP Code Stripping Bug - "A scripted object (probably Coffee.UIExtensions.UIParticle?) has a different serialization layout when loading." about particleeffectforugui HOT 14 CLOSED

@ZhihaoJun
umm...
It is not reproduced on my environment.

• 2021.3.28f1
• Windows IL2CPP
  • Managed Stripping Level: High
• UIParticle version: 4.1.7
  • Insatalled with UPM (https://github.com/mob-sakai/ParticleEffectForUGUI.git#4.1.7)
• Build scenes: UIParticle_Demo
  • Import from UI Particle > Samples

Could you please attach a minimal project (included Assets, Packages and ProjectSettings directories) that reproduces the issue?

Sorry for the late reply, but I'm glad the bug has been fixed.

Unfortunately, I encountered this issue again using the 4.4.0 version.
This time I was building Android version of my game.

However, I managed to solve it by putting entire UIParticle project in the Assets folder rather than in the Packages like mentioned above.

I think this issue is related to AssetBundle building process because my UI prefab is loading from an AssetBundle.
Everything is fine in the test project that is not using AssetBundle.

UIParticle version: 4.4.0
Unity version: 2021.3.28f1
IL2CPP backend

Optimization settings as below

Yeah, I upgraded Unity editor from 2022.3.7f1 to 2022.3.11f1
I just tried removing the UIParticle component, deleting the [generated] object then adding the UIParticle component again, everything works perfectly, it's a miracle
Thanks for your dedicated help, sir @mob-sakai

The issue is not reproduced on my environment...
Do you think adding the following code to UIParticle.cs would solve the issue?

[assembly:UnityEngine.Scripting.Preserve]

from particleeffectforugui.

Same problem here. Built standalone on windows platform with il2cpp backend. I got the error log when running:

My best guess is this macro that causes the bug since this is the only macro I found wrap a SerializeField of UIParticle.cs:

UIParticle version: 4.1.7
Unity version: 2021.3.28f1

🎉 This issue has been resolved in version 4.2.2 🎉

As a workaround, try the way that @ZhihaoJun said.

Hmm if I create an empty scene (same project as the one having the problem), then use UI Particle here, everything works fine... 😟

from particleeffectforugui.

• Has the project undergone a Unity version upgrade in the past?
• Are the assets assets that are loaded additionally, such as in AssetBundles? Also, were these assets built with an older version of Unity or UIParticle?
• If the assets are re-serialized, will the issue be resolved?
  AssetDatabase.ForceReserializeAssets()

I think that the root cause is the different serialization layout, meaning that the data structure differs between build time and load time.

If the same issue arises, please re-open this issue.
