Gui Buttons

Question

Hi

I'm trying to create a reset button for my camera, which is called from a different script which looks for the GUI Button being clicked? I've currently got a script called: "screenHUD" and a camera script called "orbit_camera" (both in Java) i need some way for the Orbit_camera script to listen for the ScreenHud button.

 Pusedo code in Orbit_camera script:
 
 if(input == button1InscreenHUDscript)
 {
  doThisFunction
 }

Why have it listen for the other one? Why not just have the other one yell at the first when it's doing something?

Example :

//Orbit_Camera script

function MyFunction(){ //do stuff }

//screenHUD script 
var orbitScript : Orbit_CameraScriptName ;
 
function Start(){
   //assuming these scripts are on the same object
   orbitScript = gameObject.GetComponent(Orbit_CameraScriptName) as Orbit_CameraScriptName ;
}
 
function OnGUI(){
   if(GUI.Button(Rect(5,5,50,50),"Whatever")){
       orbitScript.MyFunction();
   }
}

It's because the orbit script uses Late update, and the only way i can effect the camera is if i call the function within the Late update: Currently i can press "a" to achieve what i want but i want to allow the user to click on a GUI Button.

//i've commented around the line

 var target : Transform; 
 
 var targetHeight = 2.0; 
 var distance = 25; 
 
 var maxDistance = 80; 
 var minDistance = 10; 
 
 var xSpeed = 250.0; 
 var ySpeed = 120.0; 
 
 var yMinLimit = -150; 
 var yMaxLimit = 100; 
 
 var zoomRate = 20; 
 
 private var x = 0.0; 
 private var y = 0.0; 
 
 private var initialPosition : Vector3;
 private var initialRotation : Quaternion;
 
 @script AddComponentMenu("Camera-Control/MouseOrbitZoom") 
 
 function Start () { 
     var angles = transform.eulerAngles; 
     x = angles.y; 
     y = angles.x; 
 
    initialPosition = transform.position;
    initialRotation = transform.rotation;
 
    // Make the rigid body not change rotation 
       if (rigidbody) 
       rigidbody.freezeRotation = true; 
 } 
 function ResetCamera () {
   transform.position = initialPosition;
   transform.rotation = initialRotation;
 
    var angles = transform.eulerAngles; 
     x = angles.y; 
     y = angles.x; 
 
   print(transform.position.x);
 }
 
 function LateUpdate () 
 { 
    if(!target) 
       return; 
     
    // If either mouse buttons are down, let them govern camera position 
    if (Input.GetMouseButton(0) || Input.GetMouseButton(1)) 
    { 
    x += Input.GetAxis("Mouse X") * xSpeed * 0.02; 
    y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02; 
    }
 
    distance -= (Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime) * zoomRate * Mathf.Abs(distance); 
    distance = Mathf.Clamp(distance, minDistance, maxDistance); 
     
    y = ClampAngle(y, yMinLimit, yMaxLimit); 
     
    var rotation:Quaternion = Quaternion.Euler(y, x, 0); 
    var position = target.position - (rotation * Vector3.forward * distance + Vector3(0,-targetHeight,0)); 
     
    transform.rotation = rotation; 
    transform.position = position;

 }
