Loading atlas from server

[Peter83]

Hi,

I want to load atlases from asset bundles on a server.  (We need to add new sprites without having to deploy a new version of the game. The sprite names will be sent in JSON-Responses.)

I did the following:
I bundled the files of the real normal atlas into an asset bundle. The UI uses a reference atlas, which points to a normal atlas (placeholder with only on small image.)

I download the asset files with www and load the UIAtlas-Object in the bundle. Then I change the replacement in the used reference atlas.


Is this the correct way to do this? Will this work on IOS and Android devices? I tested only with the web player yet.




The code for extracting the UIAtlas-Object looks a bit long-winded. I load all Objects in the bundle, then I look for the game object and collect its UIAtlas-Component. I used this load all solution because the bundle contains 5 objects with the name of the atlas (it contains only the atlas objects). Is there a better way to get correct object?


 

1. AssetBundle atlasBundle = bigWWW.assetBundle;
2.  
3.                         Object[] objectsInBundle = atlasBundle.LoadAll ();
4.  
5.                         //Debug.Log ("objectsInBundle.Length = " + objectsInBundle.Length.ToString() );
6.  
7.                         for (int i = 0; i < objectsInBundle.Length; i++) {
8.                        
9.                                 //Debug.Log(i.ToString() + "  " + objectsInBundle[i].name + " " + objectsInBundle[i]);
10.                        
11.                                 if (objectsInBundle[i] is GameObject) {
12.  
13.                                         GameObject gameObjectWithAtlas = (GameObject)(objectsInBundle[i]);
14.                                         UIAtlas atlas = gameObjectWithAtlas.GetComponent<UIAtlas>();
15.  
16.                                         GameFieldViewBindings gameFieldViewBindings = GameObject.Find ("gameFieldBindings").GetComponent<GameFieldViewBindings> ();
17.                                         gameFieldViewBindings.atlasProcs.replacement = atlas;
18.  
19.                                         BetterList<string> spriteList = atlas.GetListOfSprites();
20.  
21.                                         //Debug.Log(i.ToString() + " is GameObject");
22.                                 }
23.                         }

Thanks for your help.

You will need to create separate asset bundles. One per platform. They are inherently incompatible with each other from what I remember.
