Timer variable set to zero

Question

I am trying to make a script that does this. Whenever the game starts and enters the scene containing the script then the variable myTimer will be set to zero and so will the Time.time so that the game can be played again from the start with the time counting up from zero instead of from where the last game ended. This is the script I have but it doesn't do what I want.

 using UnityEngine;
 using System.Collections;
 
 //ATTACH TO MAIN CAMERA, shows your health and coins
 public class GUIManager : MonoBehaviour 
 {    
     public GUISkin guiSkin;            //assign the skin for GUI display
     [HideInInspector]
     public int coinsCollected;
     public float LastTime;
     public float BestTime; 
     public float myTimer;
 
     private int coinsInLevel;
     private Health health;
     
     //setup, get how many coins are in this level
     void Start()
     {
         coinsInLevel = GameObject.FindGameObjectsWithTag("Coin").Length;    
         health = GameObject.FindGameObjectWithTag("Player").GetComponent<Health>();
     }
 
     void Update()
     {
             myTimer = Time.time;
     }
 
     //show current health and how many coins you've collected
     void OnGUI()
     {
         GUI.skin = guiSkin;
         GUILayout.Space(5f);
         if(health)
             GUILayout.Label("Time: " + myTimer.ToString("F2"));
         if(coinsInLevel > 0)
             GUILayout.Label ("Gifts: " + coinsCollected + " / " + coinsInLevel);
         if(coinsCollected > 9)
             Application.LoadLevel("Menu");
             myTimer = 0; 
     }
 }

Time.time is readonly.

If you want to track the time since the level started the set a variable to hold the value Time.time returns when gameplay starts.

You can then calculate the difference between this variable and Time.time to determine how much time has passed since.

Thanks! under this line if(coinsCollected > 9) how can I add that public float LastTime would then change to the value of the time that has passed? and how can I then change under the same line that BestTime has to change to the value of the time that has passed if the time that has passed is greater than BestTime?

Here, this should help get your started:

     private float startTime;
     
     public float levelTime {
         get { return Time.time - startTime; }
     }
     
     void Start() {
         startTime = Time.time;
     }
     
     void Update() {
         Debug.Log(levelTime);
     }

Try setting myTimer/Time.time equal to 0 in the Start function. That way each time this script is called (i.e. whenever you start the level), it will reset the time.

Side note, in your OnGUI function you have several IfThen statements. The Then statements need to be in {}'s. Technically, it will still compile correctly, but sometimes it will count later If's as they were nested within the first.

Hope this helps!
