Setting a parent of instantiated object negate all axis

Questions & Answers

Hi,
I have problems with generating prefabs in parent layer. I have two layer - Level0 (0,0,0) and Level1 (0,0,-1). When I create new prefab under Level1, it has swapped axis (0,0,1). All axis are swapped - when Level1 is (2,3,4), new object will be at (-2,-3,-4).
What I am doing wrong?

 Script:
    Level1 = GameObject.Find("Level1");
    Debug.Log(Level1.transform.position.ToString()); //0,0,-1 -> correct
    GameObject newPipe = Instantiate(pipe, new Vector3(0, 0, 0),Quaternion.identity) as GameObject;
    Debug.Log(pipe.transform.position.ToString()); //0,0,0 -> correct
    newPipe.transform.SetParent(Level1 .transform);
    Debug.Log(newPipe.transform.position.ToString()); //0,0,0 -> correct

But in the game the position is (0,0,1).

The default value for the second parameter of SetParent is true.That means the childed object keeps it’s position. since that’s 0,0,0 at start it’s the negated value of the new parent. set the parameter to false. Read about it here:
