Title: Character Rotate to Face Mouse
Post by: JBabz on August 24, 2013, 03:17:08 am

I used to have my game on the XZ plane, now I'm changing it to the XY plane.
Can anybody explain why this code doesn't work on the XY plane?

Code: [Select]

private void keyboardMovementUpdate()  {
horizontalAxis = Input.GetAxis ("Keyboard Horizontal");
verticalAxis = Input.GetAxis ("Keyboard Vertical");

Vector3 targetPoint = Camera.main.ScreenToWorldPoint (Input.mousePosition);
transform.LookAt (new Vector3(targetPoint.x, targetPoint.y, transform.position.z));
// transform.eulerAngles = new Vector3(0, 180, transform.eulerAngles.z); This line "locks" the character in his X and Y rotation.

move ();
}
Uncommenting that line makes the character jump out of rotation, commenting it makes him not move... hmm.

Thats because LookAt points the transform
"Rotates the transform so the forward vector points at /target/'s current position."

The forward vector is z, so its not going to work. If its on the XZ plane why would you NOT want to lock the x & y rotation?

And your move function is probably moving using transform.forward, which is the blue axis (z). If you're on the XY plane you probably want to move on either the X or Y.
