Title: delete reference when disable or remove panel?
Post by: markofevil3 on January 23, 2014, 06:57:39 AM
I have 2 panels with some Widgets in each. When I remove one panel, all references still be keep if the other panel are still enable. Is there any way to release all reference of disabled panel?

the meshes reference. that's the reason when i call Resources.UnloadUnusedAssets, meshes memory size doesn't reduce. but if i disable all panels and call Resources.UnloadUnusedAssets, meshes memory size reduce

You need to yield return WaitUntilEndOfFrame() before calling UnloadUnusedAssets. Otherwise the panel's draw calls won't be destroyed yet.

I have recorded video.

This is the code for test

  1. using UnityEngine;
  2. using System.Collections;
  3.  
  4. public class Test : MonoBehaviour {
  5.         public GameObject go;
  6.         public UIPanel panel;
  7.         public UIPanel panel2;
  8.         private GameObject child;
  9.                
  10.         public void DeleteRows() {
  11.                 // Destroy();
  12.                 DestroyImmediate(panel2.gameObject);
  13.                
  14.                 StartCoroutine(UnloadResource());
  15.         }
  16.        
  17.         public void Create() {
  18.                 GameObject tmp;
  19.                 if (child != null) {
  20.                         for (int i = 0; i < 200; i++) {
  21.                                 tmp = Instantiate(go) as GameObject;
  22.                                 tmp.transform.parent = panel2.transform;
  23.                                 tmp.transform.localScale = Vector3.one;
  24.                         }
  25.                 }
  26.         }
  27.        
  28.         IEnumerator UnloadResource() {
  29.                 yield return new WaitForEndOfFrame();
  30.                 Resources.UnloadUnusedAssets();
  31.         }
  32. }

UnloadUnusedAssets unloads resource such as textures. Meshes are not a loaded resource. They get cleaned up by the garbage collector. You can make sure that NGUI destroys them by putting a Debug.Log inside UIDrawCall.OnDestroy.

P.S. Never use Instantiate. Use NGUITools.AddChild(parent, prefab). Look inside that function to figure out why.
