Question by CallToAdventure · Mar 06, 2012 at 11:31 AM · camerazoom

GUITexture for each Camera

Hi there,

I tried basically everything I could but to no result. I have three cameras and I want a different guiTexture for each. Here's my code:

 var FollowCam: Camera;
 var BumperCam: Camera;
 var CannonCam: Camera;
 var Cam1 : boolean = false;
 var Cam2 : boolean = false;
 var Cam3 : boolean = false;
 var width=60;
 var height=60;
 var cameras : Camera[];
 var selectedCamera : int = 0;
 var zoom : int = 20;
 var normal : int = 60;
 var smooth : float = 5;
 private var isZoomed = false;
 var customSkin : GUISkin;
 var cambuttonWidth = 100;
 var cambuttonHeight = 50;
 
 @script AddComponentMenu("Camera-Control/Zoom")
 function Awake(){
     UpdateSelectedCamera();
 }
 function Update () {
             
     if (Cam1) {
         FollowCam.enabled = true;
         BumperCam.enabled = false;
         CannonCam.enabled = false;
     }    
     if (Cam2) {
         FollowCam.enabled = false;
         BumperCam.enabled = true;
         CannonCam.enabled = false;
     }
     if (Cam3) {
         FollowCam.enabled = false;
         BumperCam.enabled = false;
         CannonCam.enabled = true;
     }
 }
 function OnGUI () {
 GUI.skin = customSkin;
 if (GUI.Button(Rect(10,30,50,50),"", GUIStyle.none)){
           isZoomed = !isZoomed; 
      }
      if(isZoomed == true){
           camera.fieldOfView = Mathf.Lerp(camera.fieldOfView,zoom,Time.deltaTime*smooth);
      }
      else{
         camera.fieldOfView = Mathf.Lerp(camera.fieldOfView,normal,Time.deltaTime*smooth);
     }
     var cameraString = " "+(selectedCamera+1);
     if (GUI.Button(new Rect(Screen.width - cambuttonWidth,0,cambuttonWidth,cambuttonHeight),cameraString, GUIStyle.none)){
         selectedCamera++;
         if (selectedCamera==cameras.Length){
             selectedCamera=0;
             }
         UpdateSelectedCamera();
     }
 }
 function UpdateSelectedCamera(){
     for (var i=0;i<cameras.Length;i++){
         cameras[i].enabled = i==selectedCamera;
     }
 }

What I have now has a glitch too - I want to be able to zoom only a specific camera not all of them. So I assume I have to enable the zoom button only on that specific camera - w leads me to the main issue - how I hide and show a gui element?

Thanks for input and help.
