How to know if something is selected in Hierarchy or in project.
To be more specific.
I have made a prefab. Now that prefab naturaly resides in the "Project", as well as it can be in a level's "Hierarchy". How can I know if what is selected and as such displays in the "Inspector", is a prefab selected in project or something selected in the scene's hierarchy,(and then (for example) do stuff in my OnInspectorGUI() to display different GUI depending on the situation).
Thanks
AssetDatabase.Contains( Object ) -> true if it's in the project, false if it's in the scene.
Simplest & best solution (GetPrefabType will still return Prefab type for prefabs in the scene)
I recently ran in to the very same issue and found this question. I although figure you have solved it by now as the question was written a while ago - but for anyone stumbling into this question here's a possible solution. What did it for me was to use PrefabUtility.
if (PrefabUtility.GetPrefabType(target)==PrefabType.None)
// In Hieararchy
else
// In Project View
This works best in my opinion because all the other solutions also count Prefab $$anonymous$$ode as in the Hierarchy.
This code is now obsolete however so for anyone new:
private void OnEnable()
{
if (PrefabUtility.GetPrefabInstanceStatus(script.gameObject) == PrefabInstanceStatus.NotAPrefab)
Debug.Log("Selected in Project or Prefab $$anonymous$$ode");
else
Debug.Log("Selected in Hierarchy");
}
Throw this into your Prefab's editor script and it will debug which mode you selected your Prefab in.
For whoever stumbles upon this and looking specifically for gameobjects:
test for
gameObject.scene.IsValid()
if will return false when in project window
if(!gameObject.scene.IsValid())
{
//true if the go is in a scene
//false if is in project window
}
This is not the absolute perfect solution, but I found it to be a little more settling than the others in this post. I noticed that objects have hideflags on them that govern where they are visible in the editor. I found out that when you use Resources.FindObjectsOfTypeAll<>() to locate components (Resources.FindObjectsOfTypeAll includes disabled components as well as ones on disabled GameObjects), any objects in the project window will come with the HideInInspector hideflag set on it and the ones in the hierarchy come with No hideflags. I don't know enough about the internal operations of Unity to determine the accuracy of this fix, but it seems to be working flawlessly for me.
Here is an example:
public T[] FindObjectsOfTypeIncludingDisabled<T>() where T : Component
{
T[] components = Resources.FindObjectsOfTypeAll<T>();
if (components.Length == 0)
{
return new T[0];
}
List<T> allComponents = new List<T>();
for (int i = 0; i < components.Length; i++)
{
T currentComponent = components[i];
if (currentComponent.hideFlags != HideFlags.None)
{
continue;
}
allComponents.Add(currentComponent);
}
return allComponents.ToArray();
}
I'm not sure if this is the perfect way, but if Selection.transforms.Length == 0, it is selected in Project.
