C# Integer across 2d sprites

Hello all,

I am trying to create a 2d game where right now I have 3 sprites every time you click the sprite it takes one away from an integer however when you click on one it counts down from 3 to 2 then if I click the other one it counts from 3 to 2 again.

Code:

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class Lives : MonoBehaviour
7. {
8.  
9.     //When I want to take one off numberOfLives I just type 'numberOfLives = takeAwayLives(numberOfLives);'
10.  
11.     public BoxCollider2D BoxCollider2D;
12.     public GameObject Cat1;
13.     public GameObject Cat2;
14.     public GameObject Cat3;
15.     int numberOfLives = 3;
16.     public GameObject Splat;
17.  
18.     void Start()
19.     {
20.         Debug.Log (numberOfLives);
21.         Splat.gameObject.GetComponent<SpriteRenderer>().enabled = false;
22.         this.gameObject.GetComponent<SpriteRenderer>().enabled = true;
23.     }
24.  
25.     public int takeAwayLives(int number)
26.     {
27.         int ret;
28.         ret = number - 1;
29.         return ret;
30.  
31.     }
32.  
33.     void OnMouseDown()
34.     {
35.  
36.         if(numberOfLives > 0)
37.         {
38.             numberOfLives = takeAwayLives(numberOfLives);
39.             Debug.Log(numberOfLives);
40.             StartCoroutine(afterClick());
41.         }
42.     }
43.  
44.     IEnumerator afterClick()
45.     {
46.         this.GetComponent<Animation>().Play("Splat");
47.         this.BoxCollider2D.enabled = false;
48.         yield return new WaitForSeconds(1);
49.         if (numberOfLives == 2)
50.         {
51.             Cat1.gameObject.GetComponent<SpriteRenderer>().enabled = true;
52.         }
53.         if (numberOfLives == 1)
54.         {
55.             Cat2.gameObject.GetComponent<SpriteRenderer>().enabled = true;
56.         }
57.         if (numberOfLives == 0)
58.         {
59.             Cat3.gameObject.GetComponent<SpriteRenderer>().enabled = true;
60.         }
61.         this.gameObject.GetComponent<SpriteRenderer>().enabled = false;
62.         this.gameObject.GetComponent<SpriteRenderer>().enabled = false;
63.         Splat.gameObject.GetComponent<SpriteRenderer>().enabled = true;
64.         yield return new WaitForSeconds(0.2f);
65.         Splat.GetComponent<Animation>().Play("Splat Fade OUt");
66.         yield return new WaitForSeconds(2f);
67.         Splat.gameObject.GetComponent<SpriteRenderer>().enabled = false;
68.     }
69. }
70.  

Any help would be appreciated

Thanks

 

Every Instance of your class 'Lives' gives each instance 3 lives. That's why each sprite instance of class 'Lives' has 3 lives.

 

...And to fix that, you might simply put the keyword "static" in front of "int numberOfLives = 3".
