(SOLVED) Texture only shows after ALT+TAB

I have this script that generates a texture wave form from an audioclip in audiosource.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6.  
7.  
8.  
9. public class wave : MonoBehaviour
10.  
11. {
12. [SerializeField] public AudioClip audio;
13.  
14. [SerializeField] public AudioClip CloneAudioClip;
15.  
16. [SerializeField] public Image waveform;
17. public Texture tex;
18.  
19.  
20. public void WaveTexture() {
21.    
22.     this.audio = GameObject.Find("Controller").GetComponent<AudioSource>().clip;
23.        
24.      
25.         AudioClip newAudioClip = AudioClip.Create(name, audio.samples, audio.channels, audio.frequency, false);
26.         float[] copyData = new float[audio.samples * audio.channels];
27.         audio.GetData(copyData, 0);
28.         List<float> monoData = new List<float>();
29.         for (int i = 0; i < copyData.Length; i+=2)
30.         {
31.             monoData.Add(copyData[i]);
32.         }
33.         newAudioClip.SetData(monoData.ToArray(), 0);
34.      
35.  
36. Texture2D PaintWaveformSpectrum(AudioClip audio, float saturation, int width, int height, Color col) {
37.      Texture2D tex = new Texture2D(width, height, TextureFormat.RGBA32, false);
38.      float[] samples = new float[audio.samples];
39.      float[] waveform = new float[width];
40.      audio.GetData(samples, 0);
41.      int packSize = ( audio.samples / width ) + 1;
42.      int s = 0;
43.      for (int i = 0; i < audio.samples; i += packSize) {
44.          waveform[s] = Mathf.Abs(samples[i]);
45.          s++;
46.      }
47.      for (int x = 0; x < width; x++) {
48.          for (int y = 0; y < height; y++) {
49.              tex.SetPixel(x, y, Color.black);
50.          }
51.      }
52.      for (int x = 0; x < waveform.Length; x++) {
53.          for (int y = 0; y <= waveform[x] * ((float)height * .75f); y++) {
54.              tex.SetPixel(x, ( height / 2 ) + y, col);
55.              tex.SetPixel(x, ( height / 2 ) - y, col);
56.          }
57.      }
58.    
59.      tex.Apply();
60.    
61.      return tex;
62. }
63.  
64.  
65.  
66.  
67.  
68.  
69. var color = new Color32(47, 157, 43, 255);
70.  
71. waveform.material.mainTexture = PaintWaveformSpectrum(newAudioClip,1, 5400,400,color);
72.  
73.  
74.  
75. }
76.  
77.  
78. }
79.  

The Audioclip is obtained from this script:

Code (CSharp):

1. IEnumerator GetAudioClip()
2.  
3.     {
4.  
5.         var path = "file://" + SongData.fileName;
6.         // Start downloading
7.          using (var download = new WWW(path))
8.         {
9.            GameObject.Find("waveform").GetComponent<RectTransform>().localScale = new Vector2(0,0);
10.             // Wait for download to finish
11.             yield return download;
12.             // Create ogg vorbis file
13.             var clip = download.GetAudioClip();
14.             // Play it
15.             if (clip != null)
16.             {
17.                AudioClip song = clip;
18.                AudioSource.clip = song;
19.  
20.                 Debug.Log ("File Loaded!");
21.  
22.  
23.             GameObject.Find("slider").GetComponent<Slider>().minValue = 0;
24.             GameObject.Find("slider").GetComponent<Slider>().maxValue = AudioSource.clip.length;
25.             GameObject.Find("waveform").GetComponent<RectTransform>().localScale = new Vector2(1,1);
26.  
27.             GameObject.Find("waveform").GetComponent<wave>().Invoke("WaveTexture", 1);
28.  
29.             }
30.             else     // Handle error
31.             {
32.                 Debug.Log("Ogg vorbis download failed. (Incorrect link?)");
33.  
34.                 AudioClip song = Resources.Load<AudioClip>("badliar");
35.                 AudioSource.clip = song;
36.  
37.  
38.             GameObject.Find("slider").GetComponent<Slider>().minValue = 0;
39.             GameObject.Find("slider").GetComponent<Slider>().maxValue = AudioSource.clip.length;
40.             GameObject.Find("waveform").GetComponent<RectTransform>().localScale = new Vector2(1,1);
41.  
42.  
43.             }
44.  
45.         }
46.  
47.     }
48.  

Somehow the texture only apply when i hit ALT+TAB and return to the editor. In Built mode, it doesnt show at all.

Any suggestions?

 

Update:
When i put an imported audio (from assets) into the audiosource, this doesn't happen.

I tried to invoke the waveTexture() function with 5 / 10 seconds delay to wait for the file to read, but it doesn't work.
ALT+TAB immediately after the load or after works every-time..

Anyone can help me?

 

SOLVED!

Refreshing the image solved the problem:

/// . enable = false;
/// . enable = true;
