How to increase score by one per second when you are holding an object

Questions & Answers

Hello. I’m working on a game in which there are 2 ways of scoring. 1- 1point/sec while holding a ball. 2- 5 points if you drop the ball in a basket. I have multiple questions in this but I’d like to focus on the 1pt/sec part for now.

Here’s my code (sorry it’s pretty sloppy, I’m kind of new):

	public int score;
	private bool hasBall;
	private float startTime;

	void Start()
	{
		score = 0;
		hasBall = false;
		startTime = Time.time;
	}

	void OnTriggerEnter(Collider other)
	{
		if (other.gameObject.tag == "ball")
		{
			//Destroy(other.gameObject);
			other.gameObject.transform.parent = gameObject.transform;
			hasBall = true;
		}
		else
			hasBall = false;

	}

	void Update()
	{
		if (Input.GetKeyDown("space"))
			print("throwBall");
		 
		if(hasBall)
			score = (int)(Time.time - startTime);

		Debug.Log("Score: " + score);

	}

This works for giving me 1 point per second, but it doesn’t recognize when I pick it up as the start time. My debug log often will say I have “Score: 5” the first second I pick it up.

Delta time will give you the time passed since the previous frame/update. Use that to get how long the ball has been held. Whenever its been held for over a second add that to the score and subtract it from your time counter.

    public int score;
    private bool hasBall;
    private float heldTime = 0.0f;
 
    void Start()
    {
       score = 0;
       hasBall = false;
    }
 
    void OnTriggerEnter(Collider other)
    {
       if (other.gameObject.tag == "ball")
       {
         //Destroy(other.gameObject);
         other.gameObject.transform.parent = gameObject.transform;
         hasBall = true;
       }
       else
         hasBall = false;
    }
 
    void Update()
    {
       if (Input.GetKeyDown("space")){
         print("throwBall");
		 heldTime = 0.0f;
		}
 
       if(hasBall){
	     heldTime += Time.deltaTime;
		 if(heldTime >= 1){
			score += (int)heldTime;
			heldTime -= (int)heldTime;
		 }
		}
 
       Debug.Log("Score: " + score);
    }
