Code:
function Start(){
Cursor.lockState=CursorLockMode.Locked;
}
function OnGUI () {
transform.Rotate(0,Input.GetAxis("Mouse X"),0);
transform.Rotate(Input.GetAxis("Mouse Y"),0,0);
transform.rotation.z=0;
}
But the rotation along z axis is not changing to zero.
First of all, i believe you meant to use Update instead of OnGui;
Since altering a transform's position/rotation have implicity implications in phisics, every time you alter them, there's a bunch of callbacks inside Unity, mainly, OnTransformChanged()/OnRotationChanged(). So, every time you change the transform, do it only once, that's why Unity will not allow you to assign their values individually like this:
transform.position = new Vector3(0,0,0); // for example, instead of
transform.position.x = 0;
transform.position.x = 0;
transform.position.x = 0;
And you also need to use
transform.rotation = Quaternion.Euler (new Vector3 (bla,ble,0) );
to change a transforms angle.
transform.rotation.z = 0can't just move toStart()— the lines before it can modify z, for 2 reasons that may not be obvious. 1) Rotation axes aren't globally orthogonal: combinations of x&y rotations can yield z rotations (see link above for examples) 2)transform.rotation.zis not a z axis rotation angle. It's one of the imaginary components of a quaternion, representing the z component of the rotation axis scaled by the sine of half the rotation angle. It's not meaningful to change alone.transform.eulerAnglesis closer, but still not a universal fix. Rotations are weird \$\endgroup\$
