Question Why my texture change script doesnt work?

So i am making a 2d pixel game and i want my map sprite to update every second. I have 4 different textures, and made a script which changes sprite texture every 1 second, but for some reason it doesnt work. What could be wrong?

Here s script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ChangeTexture : MonoBehaviour
6. {  
7.     public GameObject map;
8.     public SpriteRenderer SpriteRenderer;
9.  
10.     public Sprite map0;
11.     public Sprite map1;
12.     public Sprite map2;
13.     public Sprite map3;
14.  
15.     IEnumerator wait1sec(){
16.         yield return new WaitForSeconds(1);
17.     }
18.  
19.     void UpdateTexture(){
20.         SpriteRenderer.sprite = map1;
21.         wait1sec();
22.         SpriteRenderer.sprite = map2;
23.         wait1sec();
24.         SpriteRenderer.sprite = map3;
25.         wait1sec();
26.         SpriteRenderer.sprite = map0;
27.         wait1sec();
28.     }
29.  
30.     void Start(){
31.         UpdateTexture();
32.     }
33. }

 

Hello,

Wait1Seconds doesn't work that way. You must write your code below yield return, then a thread will wait for it. Could you please try the following:

Code (CSharp):

1.     IEnumerator UpdateTexture(){
2.         SpriteRenderer.sprite = map1;
3.         yield return new WaitForSeconds(1);
4.         SpriteRenderer.sprite = map2;
5.         yield return new WaitForSeconds(1);
6.         SpriteRenderer.sprite = map3;
7.         yield return new WaitForSeconds(1);
8.         SpriteRenderer.sprite = map0;
9.     }
10.  
11.     void Start(){
12.         StartCorutine(UpdateTexture());
13.     }

 

Why not just make this an animation and be done with it?

No code, no fuss, no muss, no debugging and especially, no coroutines...

 

thank, will try

 

well i am new to c# and unity in general. And… I like programming

 

Thank you very much! Courutine did only one loop so i added "
StartCoroutine(UpdateTexture());" in "UpdateTexture()" IEnumerator so it runs for ethenity!
