Using UI button to change movie textures on object

Hi there,

I'm just new to Unity and for a project I'm trying to change movie textures on an object (cube) with an UI button.
I'm able to change the textures with the space bar (see example script below) but I can't figure out how to use an UI button instead of the space bar.

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using UnityEngine.UI;
5. using UnityEngine.EventSystems;
6.  
7. public class CreateTexture : MonoBehaviour {
8.     public Texture[] textures;
9.     public int currentTexture;
10.  
11.     void Start()
12.     {
13.  
14.     }
15.  
16.     // Update is called once per frame
17.     void Update() {
18.  
19.         if (Input.GetKeyDown(KeyCode.Space))
20.  
21.         {
22.             currentTexture++;
23.             currentTexture %= textures.Length;
24.             GetComponent<Renderer>().material.mainTexture = textures[currentTexture];
25.         }
26.  
27.     }
28. }
29.  
30.  

So above script does exactly what I want. I just want to use an UI button instead of the spacebar

Cool this already helped out! Now I'm able to change the materials through a UI button click Thing is, the movie (set as material) won't play anymore. I do have a 'play movie script' on the object though:

Code (csharp):

1.  
2.  
3. using UnityEngine;
4. using System.Collections;
5.  
6. public class PlayMovie : MonoBehaviour {
7.  
8.     // Use this for initialization
9.     void Start () {
10.  
11.         MovieTexture movie = GetComponent<Renderer>().material.mainTexture as MovieTexture;
12.         movie.Play();
13.         movie.loop = true;
14.     }
15.    
16.     // Update is called once per frame
17.     void Update () {
18.    
19.     }
20. }
21.  
22.  

If I just assign a material - with a movie assigned to it - to the object it works perfectly well. However when the material is changed with the UI button, the script doesn't start the movies anymore.

Any thoughts on this?

 

Nevermind, I think I got this! Of course I need to put my code in the void update, otherwise it won't load when the material is changed
