how to dynamic load Textures to sprite collection

[frozen]

Hello Unikron,

I need to load some textures which are runtime download from game server. so that I can change user's avatar or other specify elements.
There is my thought:
1. load textures to Texture2D format.
2. create or use a exist spriteCollection to place these texture2ds by order.
3. use the collection to game.

In tk2d's demo code runtimespritecollection. there is only way to load a texture and parsetext way to create a collecton. although it is a good solution, but still don't match my need..

After search some posts in forum.
such that http://2dtoolkit.com/forum/index.php?topic=1525.0
still have some confuse in flow and specific code.
Could you show me a whole steps and elegant way to finish this need?

thank you very much.

2D Toolkit doesn't do runtime atlasing. You will need to build your runtime atlas yourself, possibly using Texture2D.PackTextures. After you have the atlas packed, you can create a sprite collection as shown in the runtime sprite collection samples.

ps:
I want to place texture into spriteCollection not one time but many different time
that is a additional operate to collection ,just like use editor way.
