Question Help Need: Trouble with BuyTower() function in tower defense game - Vector3 position issue

I’m having trouble with the BuyTower() function in my tower defense game. The currentTurretPosition shows the correct Vector3 value, but when I call the BuyTower method and print the position value using Debug.Log, it shows the vector (0,0,0) instead of the expected value.

Here’s my code:

Code (CSharp):

1. void OnMouseUp()
2. {
3.     // toggle ShopUI
4.     if (!shopUI.gameObject.activeSelf && IsTowerEmpty())
5.     {
6.         currentTurretPosition = transform.position;
7.         Debug.Log(currentTurretPosition);
8.         shopUI.gameObject.SetActive(true);
9.     }
10. }
11.  

Code (CSharp):

1. private void BuyTower(int cost, int towerType, Vector3 position)
2. {
3.     if (GameManager.instance.coin >= cost)
4.     {
5.         Debug.Log(position);
6.         tower = Instantiate(towerPrefab[towerType], position, Quaternion.identity);
7.         GameManager.instance.coin -= cost;
8.     }
9. }

Can anyone help me figure out what’s going wrong? Thanks in advance!

 

I don't see where in the code above you call BuyTower()...

 

Sorry that I didn't provide all the code
here

Code (CSharp):

1.     void Start()
2.     {
3.         normalTowerButton.onClick.AddListener(() => BuyTower(100, 0, currentTurretPosition));
4.         laserTowerButton.onClick.AddListener(() => BuyTower(200, 1, currentTurretPosition));
5.         missileTowerButton.onClick.AddListener(() => BuyTower(300, 2, currentTurretPosition));
6.     }

 

you have added your method on start event, "currentTurretPosition" is a value type it will make a copy of the value you passing in that start frame, it's mean your currentTurretPosition wont get update on other frame.

what you can do is, create a new class call "TurrentData" with "currentTurretPosition" in it. and then you can pass that in as reference type.

 

That fixed my issue thank you
