Title: Reading Sprite Pixels from tk2d Generated Atlas
Post by: drkucho on January 20, 2015, 09:18:24 pm

how can i do this ? i need the coordinates / bounds data from each sprite inside atlas, i am doing my tests using the tk2dCollectionData properties but no luck, i have tried regionX, regionY, regionW and regionH but these seems to be the coordinates for the sprite sheet :-(

Its not directly exposed because a sprite could be non-rectangular, etc. We don't store a rect but you can guess from teh geometry as described above.

Look for SetClippedSpriteGeom, its in the  tk2dSpriteGeomGen class.

Nope, the only thing that gets stored is the sprite geometry, and that can be non-rectangular and span multiple areas of the atlas (eg. sprite dicing). Its meaningless to have a texture rect in the general context of tk2d.
