Detailed Description

Drawing OpenGL ES primitives.

• drawPoint
• drawLine
• drawPoly
• drawCircle

You can change the color, width and other property by calling the glColor4ub(), glLineWitdh(), glPointSize().

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.

Function Documentation

void ccDrawCircle	(	CGPoint	center,
		float	radius,
		float	angle,
		int	segments,
		BOOL	drawLineToCenter
	)

draws a circle given the center, radius and number of segments.

void ccDrawCubicBezier	(	CGPoint	origin,
		CGPoint	control1,
		CGPoint	control2,
		CGPoint	destination,
		int	segments
	)

draws a cubic bezier path

Since:

v0.8

void ccDrawLine	(	CGPoint	origin,
		CGPoint	destination
	)

draws a line given the origin and destination point

void ccDrawPoint

(

CGPoint

point

)

draws a point given x and y coordinate

void ccDrawPoints	(	CGPoint *	points,
		unsigned int	numberOfPoints
	)

draws an array of points.

Since:

v0.7.2

void ccDrawPoly	(	CGPoint *	vertices,
		int	numOfVertices,
		BOOL	closePolygon
	)

draws a poligon given a pointer to CGPoint coordiantes and the number of vertices. The polygon can be closed or open

void ccDrawQuadBezier	(	CGPoint	origin,
		CGPoint	control,
		CGPoint	destination,
		int	segments
	)

draws a quad bezier path

Since:

v0.8
