How to keep score?

Questions & Answers

Hello,

I just recently started Unity and am now starting to script with Javascript. I currently have this code so far that I found on here:

function OnTriggerEnter(collisionInfo : Collider){
      Destroy (gameObject);
}

This destroys the object but I want to be able to show it in GUI Text on the top left. Does anyone know how to score the amount of objects you destroy/take?

you need an object somewhere that stores a variable (in this case an int would likely do). then just before your call to destroy() call a function on this object to increase or decrease the score appropriately. For example, place this script on an empty game object in your scene.

public ScoreKeeper : MonoBehaviour
{
     public static int Score;
     
     void Awake()
     {
          Score = 0;
     }

    void OnGUI()
    {
        GUI.Label(new Rect(0, 0, 100, 25), "Score: " + Score);
    }
}

Then since score is a static variable, you can just change it like this.

ScoreKeeper.Score++;
