A fast, easy to use, free, and community supported 2D game engine
I have to admit I'm a total newbie when talking about OpenGL, so here's a question about openGL and/or cocos2d:
I have a series of shapes (circles, ovals, polygons, etc) and I want to "fill" each one of them with different textures (some pattern): is this even possible? can I constraint a sprite to a certain mask and fill that sprite with a pattern?
Maybe using RenderTexture, but I don't know how...
Can anyone point me to the right direction?
thanks!
I'm not sure if this is what you want, but you can 'fill' polygons with a certain texture.
Look at the first example of "AtlasTest" test. It renders polygons "filled" with a texture.
yes, that definitively looks like what I'm after, but does the texture always ends distorted?
mmm.. where can I learn more about the implementation details of TextureAtlas? or where should I start reading to learn more about it?
In the meantime, I'll keep reading the source :-)
this post might help you:

go directly to the "texture coordinates" section.
basically the cocos2d texture atlas implements:
- texture coordinates
- vertices
- colors
if you don't want "distortion" you should modify the texture coordinates according to your needs.
