Timer Ontrigger

Question

Hi everyone,

I have a timer script in which i have a public void which is called by an Ontrigger event on another script. I need this public void to start a timer which should be set to 0 before that.

Problem is, my timer starts as soon as I launch the game.

Do you have any ideas on how I should do it ?

(i'm using C# btw)

Thanks a lot

You almost got it ! You can just use the same solution as you stopped your timer. Use your variable bool started as a trigger to start it.

Edit: Also rename your method Start() to something else. Unity automatically call the Start() method when the object is instantiated.

Here is the corrected code:

 public class Timer : MonoBehaviour {
 
     public Text timerText;
     private float startTime;
     private bool finished = false;
     private bool started = false;
  
     void Update () 
     {      
         if(!started || finished)
             return;
       
         float t = Time.time - startTime;
 
         string minutes = ((int) t/60).ToString();
         string seconds = (t%60).ToString("f2");
 
         timerText.text = minutes + ":" + seconds;      
     }
 
     public void StartTimer ()
     {
         started = true;
         startTime = Time.time;
     }
 
     public void StopTimer()
     {
         finished = true;
         timerText.color = Color.yellow;      
     }   
 }

My code is :

public class Timer : MonoBehaviour {

  public Text timerText;
  private float startTime ;
  private bool finished = false;
 private bool start = false;
 
  void Update () {
      
      if(finished)
          return;
      
      float t = Time.time - startTime;
      
      string minutes = ((int) t/60).ToString();
      string seconds = (t%60).ToString("f2");
      
      timerText.text = minutes + ":" + seconds;
      
  }
  
   public void Start ()
  
  {
     start = true;
      startTime = Time.time;
  }
  
  public void Finish()
  {
      finished = true;
      timerText.color = Color.yellow;
      
  }

}

I know I should do something with my void update and my public void start but I don't really know what it is.
