Hello, I have a problem, so basically I am making a game where you try to catch balls that are falling from the sky. Now, I made a script that adds a point, plays a sound and destroys the ball every time it collides with the player object.
Script :

public AudioSource tickSource;
public Text text;
public SpawnTimeUpgrade cost;
public float points;

void Start ()
{
	tickSource = GetComponent<AudioSource> ();
}
	
public void OnCollisionEnter2D (Collision2D col)
	{

	if(col.gameObject.name == "New Sprite(Clone)")
	{
		tickSource.Play ();

		points += 1;

		text.text = points.ToString() + " POINTS";

		Destroy(col.gameObject);
	}
}

I also have an upgrade button that spends your points in order to get better stuff.
Script :

public Catch points;
public SpawnItems spawnTime;
public float cost;
public int count;
private float baseCost;

void Start ()
{
	baseCost = cost;
}

public void PurchasedItem ()
{
	if (points.points >= cost) {
		points.points -= cost;
		count += 1;
		spawnTime.spawnTime -= 0.1f;
		cost = Mathf.Round (baseCost * Mathf.Pow (1.15f, count));
	}
		
}

Now the problem with this is when I buy the upgrade, the points don’t update, they update only when the ball collides with the player object again, I have tried many stuff, but I cannot get it to work. So basically all I want is the points to update once you buy an upgrade. Which for me as a beginner is quite hard…

You are not updating the text component in PurchaseItem()

public void PurchasedItem ()
 {
     if (points.points >= cost) {
         points.points -= cost;
         // The next line is missing
         points.text.text = points.points.ToString() + " POINTS";
         count += 1;
         spawnTime.spawnTime -= 0.1f;
         cost = Mathf.Round (baseCost * Mathf.Pow (1.15f, count));
     }
 }
