TexturePacker for 2D

Howdy Guys,

I've created an atlas through texture packer and have used the texturepacker importer script for Unity. I followed the tutorial at https://www.codeandweb.com/blog/2014/03/28/using-spritesheets-with-unity and it seems the script does its work and recognizes the individual textures in the Unity Editor.

What I want to do is develop a way that will allow me to say either "SomeGameObject.GetSpriteFromAtlas(name)" or "Material.GetSpriteFromAtlas(name)". The issue I am facing is there doesnt seem to be a way to do this without me writing my own parser(whether its json, xml or any other format), create a 2dTexture from the atlas, THEN creating a sprite from the texture.

The reason for my desire to create sprites dynamically this way is because if I am pooling game objects, I need a way to reassign a game object's sprite renderer to a different sprite based on a frame number.

I dont necessarily have a problem with this since I've done something similar in Flash, but with all of the support for Unity and my inexperience with Unity ATM, I feel there should be a way to do this already.

If there is someone that can help me out or point me in the right direction I'd appreciate it.
