Detailed Description

Drawing OpenGL ES primitives.

  • ccDrawPoint, ccDrawPoints
  • ccDrawLine
  • ccDrawRect, ccDrawSolidRect
  • ccDrawPoly, ccDrawSolidPoly
  • ccDrawCircle
  • ccDrawQuadBezier
  • ccDrawCubicBezier
  • ccDrawCatmullRom
  • ccDrawCardinalSpline

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 CCDrawNode
