Public Methods

Method	Description
Dispose ( ) : void
PrimitiveBatch ( int bufferSize = 500 ) : System
addVertex ( Vector2 vertex, Color color, PrimitiveType primitiveType ) : void
begin ( ) : void	draws directly in screen space at full viewport size
begin ( Matrix &projection, Matrix &view ) : void	Begin is called to tell the PrimitiveBatch what kind of primitives will be drawn, and to prepare the graphics card to render those primitives. Use camera.projectionMatrix and camera.transformMatrix if the batch should be in camera space.
drawArrow ( Vector2 start, Vector2 end, float length, float width, bool drawStartIndicator, Color color ) : void
drawCircle ( Vector2 center, float radius, Color color, int circleSegments = 32 ) : void
drawPolygon ( Vector2 position, Vector2 vertices, Color color ) : void
drawPolygon ( Vector2 vertices, int count, Color color ) : void
drawRectangle ( Rectangle &rect, Color color ) : void
drawRectangle ( float x, float y, float width, float height, Color color ) : void
end ( ) : void	End is called once all the primitives have been drawn using AddVertex. it will call Flush to actually submit the draw call to the graphics card, and then tell the basic effect to end.

begin() public method

Begin is called to tell the PrimitiveBatch what kind of primitives will be drawn, and to prepare the graphics card to render those primitives. Use camera.projectionMatrix and camera.transformMatrix if the batch should be in camera space.

start	Vector2
end	Vector2
length	float
width	float
drawStartIndicator	bool
color	Color
return	void

drawCircle() public method

public drawCircle ( Vector2 center, float radius, Color color, int circleSegments = 32 ) : void
center	Vector2

end() public method

End is called once all the primitives have been drawn using AddVertex. it will call Flush to actually submit the draw call to the graphics card, and then tell the basic effect to end.
