Rotation resets to 0,0,0 not prefab's

Questions & Answers

Hello all.

I am instantiating a prefab that has a rotation of 330,180,0 like this:

Vector3 pos = new Vector3(Random.Range(-5,25), 0, 25 );
Instantiate(prefab, pos, Quaternion.identity);

Problem is, when I see the object in game, after it’s been instantiated it resets the rotation back to 0,0,0. The prefabs script does not touch the rotation and it doesn’t have a rigidbody.

I read in another question that Quaternion.Identity is supposed to keep the prefab’s rotation.

What am I doing wrong?

Thank you.

You are specifying Quaternion.identity to use for rotation. Quaternion.identity is 0,0,0 only.

Try this:

    Vector3 pos = new Vector3(Random.Range(-5,25), 0, 25);
    GameObject go = Instantiate (prefab) as GameObject;
    go.transform.position = pos;
    
    //or, go.transform.localPosition = pos;

When you set it to “Quaternion.identity”, you’re zeroing the rotation. I’m not sure if you can copy the rotation of a prefab, but you can set it after instantiating it. It’ll be something like this:

Vector3 pos = new Vector3(Random.Range(-5,25), 0, 25 );
GameObject newObject = (GameObject) Instantiate(prefab) as GameObject;
newObject.transform.position = pos;
newObject.transform.localEulerAngles = new Vector3(x,y,z);
