Animate mesh texture using array

Questions & Answers
1

I have a sphere and would like the sphere to have an animated water texture. I’m trying to swap out the textures using an array. What am I doing wrong?

using UnityEngine;
using System.Collections;

public class animateTexture : MonoBehaviour 
{

	public Texture[] water;
	
	void Update () 
	{
		for (int i = 0; i < water.Length; i++)
		{
			StartCoroutine(MyMethod());
			renderer.material.mainTexture = water*;*

_ Debug.Log(water*);_
_ }*_

* }*

IEnumerator MyMethod()
* {*

* yield return new WaitForSeconds(1);*

* }*
}
Any advice would be much appreciated.

Try something like this:

public class TextureSwitcher : MonoBehaviour {
	
	public Texture[] texList;
	int curTex = 0;
	
	void Start () {
		StartCoroutine(Switch());
	}
	
	IEnumerator Switch(){
		yield return new WaitForSeconds(1);
		renderer.material.mainTexture = texList[curTex];
		curTex = (curTex+1) % texList.Length; // A convenient way to loop an index
		StartCoroutine(Switch());
	}
}

A few quick notes regarding your original script:

  • As written, the MyMethod() coroutine starts, waits one second, then ends.
  • Coroutines do not “block”, i.e., a function that calls one does not wait for it to finish before continuing.
  • The for loop in Update() will run through all its iterations every time Update() is called (i.e., once per frame) and thus cycle through all the textures every frame.
