Hello,

I want to create a little pokemon game for learn with AR. Actually when the camera detect two image (dracaufeuCard et tortankCard) Charizard and Blastoise appear. Bu if I click on attack button one of this pokemon acive their particules effect for make a attack during 2s.
Now I want to make a playerController for define live and power attack for the pokemon but I know how to do it.

6. public class DracaufeuScript : MonoBehaviour
7. {
8.  
9.     public Button attackButton1;
10.     public GameObject fireBall;
11.  
12.     // Start is called before the first frame update
13.     void Start()
14.     {
15.         attackButton1.onClick.AddListener(performAttack);
16.         fireBall = gameObject.transform.FindChild("FireBall").gameObject;
17.         fireBall.gameObject.SetActive(false);
18.     }
19.  
20.     // Update is called once per frame
21.     void Update()
22.     {
23.        
24.     }
25.  
26.     IEnumerator Wait() {
27.         fireBall.gameObject.SetActive(true);
28.         yield return new WaitForSeconds(2);
29.         fireBall.gameObject.SetActive(false);
30.     }
