Will be possible create a shader that works as the Tiled Background Plugin?
You put a texture in the sprite and the shader will repeat that texture in XY without stretch or zoom when is resized, simple repeat the texture you added again and again in X and Y. Also without use any parameter, like the TiledBackground plugin.
Why do in a .FX for a sprite? Because in a sprite you have frame/animations, so you can have in one sprite all the tiledBackgrounds and animations you want and simply add to layout and change the initial Frame/animation, Instead of have lots of tilebackgrounds objects for each tile. Also for Families you not will need a separate one for tiledBackgrounds, Also in a sprite allows imagepoints, custom collisions,etc...
Will be possible?
