:D Hello :D
I am currently developing a game engine. I'm using maps designed with Tiled and I placed several objects on a test map to develop the feature of loading objects as sprites/entities and I'm not able to get the correct texture rectangle for certain GID (with correct, I mean the chunk of image that I place as an object on the map), even thought that I'm looking for such GIDs on the same place that I look for pattern tiles. anyway, I have two screenshots to illustrate.
Where I am right now: bad http://ompldr.org/vaGg4eA/Captura%20de%20pantalla%20de%202013-02-15%2017:05:51.png
What I want to achieve: good http://ompldr.org/vaGg5MA/Captura%20de%20pantalla%20de%202013-02-15%2017:20:08.png
