Store initial rotation in JavaScript

Questions & Answers
1

So what I’m trying to figure out, and could not decipher from other answers found here, is exactly how to store the rotation of my ship so that I may use it to reset to zero later on in the script. I thought I was doing it correctly, but obviously I’m missing something very important here. Could someone please help me out and explain what I’m doing wrong? Again, this is Javascript.

var originalRotationZ = Quaternion;

 function Start ()
 {
  transform.rotation.eulerAngles.z = originalRotationZ; // store rotation on start
 }

This is wrong:

var originalRotationZ = Quaternion;

Quaternion is a type, not a value that you can assign to variables. It’s unclear if you’re trying to store the entire rotation or just the Z axis. So it’s either:

var originalRotationZ : float;

function Start () {
    originalRotationZ = transform.eulerAngles.z;
}

or

var originalRotation : Quaternion;

function Start () {
    originalRotation = transform.rotation;
}

You are trying to store a Quaternion in eulerAngles you can instead; store the eulerAngles in a Vector3 and then set them as shown in the first link. Or you can do this:

transform.rotation.eulerAngles.z = originalRotationZ.eulerAngles.z;

which according to Transform-eulerAngles

Do not set one of the eulerAngles axis
separately (eg. eulerAngles.x = 10; )
since this will lead to drift and
undesired rotations.
