Is it possible to draw a filled circle with cocos2d ? An outlined circle can be done using the drawCircle() function, but is there a way to fill it in a certain color? Perhaps by using pure OpenGL?

In DrawingPrimitives.m, change this in drawCricle:

glDrawArrays(GL_LINE_STRIP, 0, segs+additionalSegment);

to:

glDrawArrays(GL_TRIANGLE_FAN, 0, segs+additionalSegment);
