Question by Reubix · Jul 10, 2015 at 07:26 AM · errorscenetimer

Timer to Switch Scene, not working, New to Coding

I'm new to coding so I don't know much and having problems with a script I made. I'm trying to make a script that counts down from x amount of seconds (not visible in scene) and, when it reaches 0, switch to a different scene. MonoDevelop give me this error "Error Error: System.ArgumentException: An item with the same key has already been added. (Error: System.ArgumentException) (Assembly-UnityScript)" and below is the code I wrote, I would be overly Thankful if you could tell me where I went wrong and how to fix it

 #pragma strict
 
 var seconds : float = 5;
 
 function Update ()
 {
     seconds -= Time.deltaTime;
     
     if (seconds == 0);
     {
         Application.LoadLevel("example");
     }
 }

I actually don't find this approach amusing. Since you want the scene to get loaded after x amount of seconds (not visible in scene) and, when it reaches 0, switch to a different scene.

You can try this approach :--

 var startTime;
 private var timeLimit= 10.0;

     function Start(){
          startTIme = Time.time;
          
     }

 function Update () {
     if (Time.time > startTime+timeLimit) {
           Application.LoadLevel("example");
     }
 }



OR this would help you out..

 private var timeLimit= 10.0;
 
     function Start(){
              Invoke("LoadLevelExample", timeLimit);
     }

     function LoadLevelExample() {
         Application.LoadLevel("example");
     } 



Hope this helps.

The semicolon has not to be used in ending if statements' body. Just do:

  if (seconds <= 0)
  {
      Application.LoadLevel("example");
  }

@Reubix: try this other approach: http://answers.unity3d.com/questions/30811/change-level-after-10-secs.html It should be more "clean"...

And make sure that the level "example" has been added to the levels' list.

$$anonymous$$ost likely seconds will never be exactly zero. So you should use

 if ( senconds < 0 )
