在 Unity 中获取预制文件位置

Question

What I am trying to do is in my Start() method of a prefab GameObject in my scene is I want to get the location of where this prefab is as a string but I cannot figure out how to do this.

Example of how I am using this: I put a Sword Prefab GameObject in my scene and on Start() I would like to get the file directory of where this GameObject is in my project.

Answer 1

Include using UnityEditor;

NOTE : This will only work if the prefab is to to public.

Then use AssetDatabase.GetAssetPath to get the path of the prefab.

public GameObject prefab;
void Start(){
    string prefabPath = AssetDatabase.GetAssetPath(prefab);
    Debug.Log("Path: " + prefabPath);
}

Edit :

I did some experiment with PrefabUtility.GetPrefabType , PrefabUtility.GetPrefabObject and PrefabUtility.GetPrefabParent . PrefabUtility.GetPrefabParent solved the problem. You don't need to make the prefab public with PrefabUtility.GetPrefabParent .

void Start()
{
    GameObject prefab = GameObject.Find("PrebabTest");
    Object GameObject2 = PrefabUtility.GetPrefabParent(prefab);
    string prefabPath = AssetDatabase.GetAssetPath(GameObject2);
    Debug.Log("Path: " + prefabPath);
}

Answer 2

Get complete path from transform

public static string GetGameObjectPath(Transform transform)
{
    string path = transform.name;
    while (transform.parent != null)
    {
        transform = transform.parent;
        path = transform.name + "/" + path;
    }
    return path;
}

Answer 3

If you want to find prefab variant of an instance you should use

PrefabUtility.GetCorrespondingObjectFromSource(YourPrefabInstance)

If you want to find orginal prefab of an instance you should use

PrefabUtility.GetCorrespondingObjectFromOriginalSource(YourPrefabInstance)

It will work only in Editor mode.
