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

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

void drawCircleDeprecated	(	float	x,
		float	y,
		float	radius,
		float	angle,
		int	segs
	)

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

Deprecated:

Use drawCircle() instead. Will be removed in v0.8

void drawLine	(	CGPoint	origin,
		CGPoint	destination
	)

draws a line given the origin and destination point

void drawLineDeprecated	(	float	x1,
		float	y1,
		float	x2,
		float	y2
	)

draws a line given x1,y1 and x2,y2 coordinates

Deprecated:

Use drawLine() instead. Will be removed in v0.8

void drawPoint

(

CGPoint

point

)

draws a point given x and y coordinate

void drawPointDeprecated	(	float	x,
		float	y
	)

draws a point given point.

Deprecated:

Use drawPoint() instead. Will be removed in v0.8

void drawPoints	(	CGPoint *	points,
		unsigned int	numberOfPoints
	)

draws an array of points.

Since:

v0.7.2

void drawPoly	(	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 drawPolyDeprecated	(	float *	poli,
		int	points
	)

draws a poligon given a pointer to float coordiantes and the number of vertices

Deprecated:

Use drawPoly(vertices, numOfVertices, open) instead
