Gui Buttons

Questions & Answers
1

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;

private var initialPosition : Vector3;

    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;
