Function Documentation

draw.circle()

nil draw.circle	(	number	x,
		number	y,
		number	radius,
		color	color )

Draws a circle on the screen

draw.clipcircle()

nil draw.clipcircle	(	number	x,
		number	y,
		number	radius )

Circle scrissor, same behavior as cliprect, but as a circle

draw.cliprect()

nil draw.cliprect	(	number	x,
		number	y,
		number	width,
		number	height )

Rectangle scrissor, useful for clipping text, & masking stuff

Example:

draw.enableclip(true)
draw.clip(0, 0, 25, 10)
draw.text(0, 0 "This is some text", ...)
draw.enableclip(false)

draw.enableclip()

nil draw.enableclip

(

boolean

enable

)

Enables or disables clipping/masking

draw.gradientline()

nil draw.gradientline	(	number	start_x,
		number	start_y,
		number	endx,
		number	endy,
		color	start_color,
		color	end_color )

Draws a gradient line on the screen

draw.gradientrect()

nil draw.gradientrect	(	number	x,
		number	y,
		number	width,
		number	height,
		color	top_left,
		color	top_right,
		color	bottom_left,
		color	bottom_right )

Draws a gradient rectangle on the screen

draw.hdoublegradientrect()

nil draw.hdoublegradientrect	(	number	x,
		number	y,

		color	left_top,
		color	center_top,
		color	right_top,
		color	left_bottom,
		color	center_bottom,
		color	right_bottom )
