Rotation limiting problem

Unity Engine
1

Hi folks,

I’m making an object the camera is attached to rotate on the X axis when the mouse moves to the top 5 or bottom 5 pixels on the screen. Standard rts kinda navigation.

It’s working fine, but I’m running into a problem with limiting the rotation. Because the X rotation of the object is set to 0 initially, if I rotate down then it flips to a rotation of 359 degrees, rather than -1.

If I set the initial rotation to, say 90, it pooches other scripts :frowning:

Any ideas on a workaround for this, you clever folks, you?

var camyoffset : int = 5;
var camrot : float = 5;

function Update () {
	if(Input.mousePosition.y < camyoffset  transform.localEulerAngles.x > -20) {
		transform.Rotate((camrot * -1 * Time.deltaTime), 0, 0);
	}
	if(Input.mousePosition.y > Screen.height-camyoffset  transform.localEulerAngles.x < 20) {
		transform.Rotate((camrot * Time.deltaTime), 0, 0);
	}
}

Cheers,

if you want to work with negative values…

float rot = transform.localEulerAngles.x;
if(rot > 180)
  rot -= 360;

this will give you a value between -180 → 180

Awesome stuff, thanks James!
