public static var LINES: int;
public static int LINES;
public static LINES as int

Description

Mode for Begin: draw lines.

If you want to draw something 2D in screen space then probably you will want to use GL.LoadOrtho or GL.LoadPixelMatrix.
If you want something in "3D", then probably you should consider using GL.LoadIdentity followed by GL.MultMatrix with the actual 3D transform you want your stuff to be in.

See Also: GL.Begin, GL.End.
