Mouse Orbit Zoom Problem
I've modified the MouseOrbit script provided by Unity to zoom in and out using the scroll wheel, although theres a problem. The script has been modified to work on click, and it seems the zoom factor is only applied on click too.
var target : Transform; private var distance = 10.0;
var xSpeed = 250.0; var ySpeed = 120.0;
var yMinLimit = -20; var yMaxLimit = 80;
var distanceMin = 3; var distanceMax = 25;
private var x = 0.0; private var y = 0.0;
function Start () { var angles = transform.eulerAngles; x = angles.y; y = angles.x;
// Make the rigid body not change rotation
if (rigidbody)
rigidbody.freezeRotation = true;
}
function Update () {
distance -= Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime * Mathf.Abs(distance);
distance = Mathf.Clamp(distance, distanceMin, distanceMax);
if (target && Input.GetMouseButton(0)) {
x += Input.GetAxis("Mouse X") * xSpeed * 0.02;
y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;
y = ClampAngle(y, yMinLimit, yMaxLimit);
var rotation = Quaternion.Euler(y, x, 0);
var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;
transform.rotation = rotation;
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); }
I managed to achieve it by adding the wheel zoom within the if statement first, then follow it with the Mouse Input call.
if (target && camera) {
distance -= Input.GetAxis("Mouse ScrollWheel") Time.deltaTime Mathf.Abs(distance); distance = Mathf.Clamp(distance, minDistance, maxDistance);
if(Input.GetMouseButton(0)) {
Your condition:
if (target && Input.GetMouseButton(0))
only allows the update to happen when the button is down. You need to 'or' ( || ) that with 'or if the wheel moved'. You might want to store the value of the wheel input to make it easier to check that.
if (target && (Input.GetMouseButton(0) || Input.GetAxis("Mouse ScrollWheel")) )
The current condition states that if there is a target and the mouse button '0' is pressed then execute the function. How do i add the 'or' into this. I added the 'wheel moved' to a custom function, call i call that function with the 'or' statement?
