Resolved GetPrefabAssetType returns incorrect value

Hi,

I'm currently trying to create a tool to speed up workflow. The function of this tool is to add component to a list of selected prefabs, but to prevent double adding on regular/variants, I want to check if the prefab I might have accidentally selected is already a variant.

Here come's the problem, I am unable to get a return value of variant even though the asset I selected is a prefab variant, and I know it is because the icon of the prefab is with the black lines. Strangely if I create a variant of the variant, the engine returns me a value of variant instead of regular.

Recreating the scenario :
Create empty gameobject in scene;
Set gameobject as prefab;
Right click (prefab)gameobject and create prefab variant (gameobject variant);
Test code returns the (gameobject variant) as a regular prefab;
Right click (prefab)gameobject variant and create prefab variant (gameobject variant variant)
Test code returns the (gameobject variant variant) as variant prefab;


Here is the snippet of my code :

Code (CSharp):

1.  
2.     public class ParticleCheckResult
3.     {
4.         public GameObject myParSys;
5.         public string particleAddedResult;
6.     }
7.     public List<ParticleCheckResult> parSysForChecks = new List<ParticleCheckResult>();
8.     public void AddManaged()
9.     {
10.         foreach (var currPar in parSysForChecks)
11.         {
12.             GameObject assetRoot = currPar.myParSys as GameObject;
13.             string assetPath = AssetDatabase.GetAssetPath(assetRoot);
14.             GameObject contentsRoot = PrefabUtility.LoadPrefabContents(assetPath);
15.             Debug.Log(currPar.myParSys.name + " is " + PrefabUtility.GetPrefabAssetType(contentsRoot));
16.             continue;
17.     }
18.  

the GameObjects I placed in the list :


and the results :


as you can see, the base prefab is not even treated as a prefab, and the first level variant is treated as regular. Can someone enlighten me on whether this is intended behaviour, or should I use another method to check the prefab type? I'm using Unity 2019.3.9 if that should affect anything. Thanks!

 

You want to use

PrefabUtility.GetPrefabAssetType(assetRoot)

, using the prefab asset (

assetRoot

) instead of its contents (

contentsRoot

).

What you're getting the type of is the root object inside the prefab. With this, your results make sense: A regular prefab contains a non-prefab game object, a variant contains an instance of the original prefab and a variant of a variant contains an instance of the original variant.

 

Thanks a bunch man, never thought I had to use the prefab as a GameObject rather than an asset.

 

Thanks for this important clarification @Adrian.

As a side note while reading the above my head exploded.

But I understand it better now, so I got that going for me.
