   Hi, do anyone know a simple paint tutorial or example in cocos2d? (paint by touch) :-)

   Im not sure cocos2d is best for painting app. Making a Quartz based app would probably give you much more power. Is it a game too - do you need fast opengl sprite animation too? If not - read up on Quartz.

   See the RenderTextureTest (comes with cocos2d-iphone source code) for how to implement a paint-like application.

   Do you guys know how can i erase something i drawed?
   I am using the rendertexture test for a little project and i would need to have an erase tool. I have been playing with the blendfunc but i haven't been able to create an erase tool which can erase what i just drawed.
   Any help is appreciated.

   Thanks

   I managed to make it work!

   To start erasing just set your brush's texture to a totally black image and then
   [brush setBlendFunc:(ccBlendFunc) {GL_ONE_MINUS_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA}];

   to paint again:
   [brush setBlendFunc:(ccBlendFunc) {GL_ONE_MINUS_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA}];
