Difference between AssetDatabase.Contains and EditorUtility.IsPersistent

Hello,

Does anyone know if there are any differences between AssetDatabase.Contains and EditorUtility.IsPersistent functions?

Thanks!

I think AssetDabase.Contains is something you use when you are sure you are only handling asset files (textures, prefabs, whatever). But like it says in EditorUtility.IsPersistent, it does this check:

"Returns false if the object lives in the Scene."

So it could be used to check if some Object you are handing isn't actually an asset file, but only part of a scene.

Note - I've only actually used AssetDatabase.Contains...

 

Thank you for the reply. I believe AssetDatabase's documentation also states the same thing: "Returns false if object is not an asset (for example object in the Scene, or an object created at runtime)"

Hah - so my idea about it wasn't true then... maybe someone else knows better.

 

My 2 cents, 3 years later:

Looking at Unity's own C# code, I have seen that

EditorUtility.IsPersistent

is used 6x more often than

AssetDatabase.Contains

Both methods end up calling native code, which we don't have access to. So, until someone from Unity chimes in, I will stick to the seemingly preferred

EditorUtility.IsPersistent
