Question by johnq1216 · May 05, 2014 at 06:48 AM · androidmobiletouchscreen

2 Objects spawning instead of one at each update

Hi everyone. I googled everything I can find but to no avail. I want the game to spawn a missile each time the player touches the screen.

But it's spawning 2 missiles at once with each touch. It doesn't look like there are 2 missiles and I could just roll with it. But what kind of programmer would I be if I can't solve this problem?

I put some debugging logs in each conditional statement and they do count twice with each touch. I'm now at the end of my wits.

 #pragma strict
 
 var missileObject : GameObject;
 private var launcherReady : boolean;
 
 function Start(){
     launcherReady = true;
 }
 
 function Update  () {
 
 if( Input.touchCount == 1){
      
         for (var touch : Touch in Input.touches){
             var ray = Camera.main.ScreenPointToRay(touch.position);
             var hit : RaycastHit;
 
             if (Physics.Raycast (ray, hit, 100) && launcherReady) {
             
                         if(touch.phase == TouchPhase.Ended) {
                     
                          launcherReady = false;
                          
                            var cameraTransform = Camera.main.transform.InverseTransformPoint(0, 0, 0);
                          var v3 : Vector3 = Camera.main.ScreenToWorldPoint(new Vector3 (touch.position.x, touch.position.y, cameraTransform.z - 0.5));
                         var mObject = Instantiate( missileObject, v3, Quaternion.Euler(270, 0, 0));
                            mObject.GetComponent(MissileMovement).yMovement = 1;    
 
             }
          
         }
         
     }
 }
     launcherReady = true;
 
 }

You can solve this issue using a bool .....

 if(spawn){ 
  var mObject = Instantiate( missileObject, v3, Quaternion.Euler(270, 0, 0));
  spawn=false;
 }

Make this spawn bool true when the user touches i.e touchPhase==Touch.Began or where you are detecting touch

Thanks Noob_Vulcan but that didn't work. I figured it out though. There's another object that has the same script. This happened to me before. Why didn't I see this at first?
