How do I make an Angry Birds Style Scoring System?

I want to make a score system that shows a different score based on seconds.

if you have:
100 seconds remaining = 3 stars

50 seconds remaining = 2 stars

10< = 1 star with 0 seconds being 0 stars

The stars will be an image saved in the Assets.

thanks in advance

One way is to keep track of how much time has elapsed. But you want to stop that when pausing.

float timer = 60f;

void Update(){
   if(pause)return;
   if(gameOver){
      CheckTime();
      return;
   }
   timer -= Time.deltaTime;
}

void CheckTime(){
   if(time >= 100) // Draw 3 stars
   else if (time < 100 && time>= 50) //Draw 2 stars
   // and so on 
}
