Mouse Orbit and touch screen

Scripting
1

Hi to all,
i modify the “MouseOrbit” script in order to work only on mouse down; on a standard PC works fine…

var target : Transform;
var distance = 20.0;
var mySpeed = 250.0;
private var x = 0.0;
private var y = 0.0;


function Start () {
    var angles = transform.eulerAngles;
    x = angles.y;
    y = angles.x;
}


function LateUpdate () {
	if (Input.GetMouseButton(0)){
		x += Input.GetAxis("Mouse X") * mySpeed * 0.02;
		x = ClampAngle(x, xMinLimit, xMaxLimit);
		y -= Input.GetAxis("Mouse Y") * mySpeed * 0.01;
		y = ClampAngle(y, yMinLimit, yMaxLimit);
	}
	var rotation = Quaternion.Euler(y, x, 0);
	transform.rotation = rotation;
	var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;
	transform.position = position;
}


static function ClampAngle (angle : float, min : float, max : float) {
	if (angle < -360)
		angle += 360;
	if (angle > 360)
		angle -= 360;
	return Mathf.Clamp (angle, min, max);
}

…but i need to use this script with a touch screen, and there is a problem: i cannot track the finger position when it’s not pressed, so when my finger left the screen, the last know “mouse position” remains the same until i re-position my finger in another place, making the camera rotate too much in the first frame.

I need to use a sort of delay that eliminate this “firs frame problem”… any sugestion?

Thanks

Hello!

Just a quick idea, do an interpolation between the last touch and the actual one :smile:, that should smooth your camera movement.

Hope it helps :wink:

does this script work. i get the errors: xMinLimit: Unkonow identifier
