Undo.RegisterCreatedObjectUndo

Parameters

Description

Register an undo operations for a newly created object.

When the undo is performed the object will be destroyed. All newly created objects that are part of undoable state should be registered with this function.

Note: Object destruction works the same way as it does for Object.Destroy (except for the delay). This means that GameObjects will be destroyed along with all their child GameObjects.

// Creates a new game object as an operation that can be undone

using UnityEditor;
using UnityEngine;

class CreateGameObjectMenu
{
    [MenuItem("Example/Create GameObject")]
    static void CreateGameObject()
    {
        // Create GameObject hierarchy.
        GameObject go = new GameObject("my GameObject");
        GameObject child = new GameObject();
        go.transform.position = new Vector3(5, 5, 5);
        child.transform.parent = go.transform;

        // Register root object for undo.
        Undo.RegisterCreatedObjectUndo(go, "Create object");
    }
}
