Detailed Description

Drawing OpenGL ES primitives.

• ccDrawPoint
• ccDrawLine
• ccDrawPoly
• ccDrawCircle
• ccDrawQuadBezier
• ccDrawCubicBezier

You can change the color, width and other property by calling the glColor4ub(), glLineWidth(), 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,
		NSUInteger	segments,
		BOOL	drawLineToCenter
	)

draws a circle given the center, radius and number of segments measured in points

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

draws a cubic bezier path measured in points.

Since:

v0.8

void ccDrawLine	(	CGPoint	origin,
		CGPoint	destination
	)

draws a line given the origin and destination point measured in points.

void ccDrawPoint

(

CGPoint

point

)

draws a point given x and y coordinate measured in points.

void ccDrawPoints	(	const CGPoint *	points,
		NSUInteger	numberOfPoints
	)

draws an array of points.

Since:

v0.7.2

void ccDrawPoly	(	const CGPoint *	vertices,
		NSUInteger	numOfVertices,
		BOOL	closePolygon
	)

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

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

draws a quad bezier path measured in points.

Since:

v0.8
