Detailed Description

Drawing OpenGL ES primitives.

• drawPoint, drawPoints
• drawLine
• drawRect, drawSolidRect
• drawPoly, drawSolidPoly
• drawCircle
• drawQuadBezier
• drawCubicBezier
• drawCatmullRom
• drawCardinalSpline

You can change the color, point size, width by calling:

• drawColor4B(), drawColor4F()
• ccPointSize()
• glLineWidth()

Warning

These functions draws the Line, Vec2, 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
