Using TMX Tile Object as Sprite in cocos2d-x

cocos2d-x C++
1 
Cocos2d "tile objects" are not supported yet.

so I implemented "Tile Object as sprite" in Cocos2d-x.
fixed just few line.
I hope this source is helpful to someone.


I include sample source.
becarful this will change your lib.

Hi, Robert Ryu, I’ve sent an email to Riq to know if cocos2d-iphone will add this feature. As you know, I always keep the cocos2d-iphone existing classes/methods synchronously.
Anyway, thanks for your contribution!
