Decrease a value every second?

Question

Hello, I'm trying to make a little function in C# ... I'd like to decrease a value by 1 every second, here my Code:

 private int hunger= 100;
 
 void decreaseHunger(){
      while (0 < hunger) {
             Time.deltaTime -= 1; // IM SURE THIS ONE IS ULTRA WRONG
             hunger -= 1;
         }
 }
 void Update(){
    Debug.log(hunger);
 }

Thanks guys!

You're right - it is ultra wrong! Try this:

 private int hunger= 100;

 void Start(){
   InvokeRepeating("decreaseHunger", 1.0f, 1.0f);
  }
 
 void decreaseHunger(){
   if(hunger > 0) {
          hunger -= 1;
      }
  }

 void Update(){
   Debug.log(hunger);
 }

the Time.delta returns a value of how long it took to do the last update cycle. AFAIK the normal method is to have a variable called timeCountInSeconds or something, then in the update loop just do timeCountInSeconds += Time.delta;

That will give you a count showing the actual seconds

Hope this helps.
