Drawing OpenGL ES primitives.

- ccDrawRect, ccDrawSolidRect

- ccDrawPoly, ccDrawSolidPoly

You can change the color, point size, width by calling:
|
|
- ccDrawColor4B(), ccDrawColor4F()
|
|
- ccPointSize()
|
|
- glLineWidth()
|
|
|
|
@warning These functions draws the Line, Point, Polygon, immediately. They aren't batched. If you are going to make a game that depends on these primitives, I suggest creating a batch. Instead you should use DrawNode
