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, 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
