Name	rect()
Examples	rect(30, 20, 55, 55); rect(30, 20, 55, 55, 7); rect(30, 20, 55, 55, 3, 6, 12, 18);
Description	Draws a rectangle to the screen. A rectangle is a four-sided shape with every angle at ninety degrees. By default, the first two parameters set the location of the upper-left corner, the third sets the width, and the fourth sets the height. The way these parameters are interpreted, however, may be changed with the rectMode() function. To draw a rounded rectangle, add a fifth parameter, which is used as the radius value for all four corners. To use a different radius value for each corner, include eight parameters. When using eight parameters, the latter four set the radius of the arc at each corner separately, starting with the top-left corner and moving clockwise around the rectangle.
JavaScript Notes	The "@pjs crisp" directive affects how lines are rendered. You can set it with the "Playback Settings" tool in the "JavaScript" menu.
Syntax	rect(a, b, c, d) rect(a, b, c, d, r) rect(a, b, c, d, tl, tr, br, bl)
Parameters	a float: x-coordinate of the rectangle by default b float: y-coordinate of the rectangle by default c float: width of the rectangle by default d float: height of the rectangle by default r float: radii for all four corners tl float: radius for top-left corner tr float: radius for top-right corner br float: radius for bottom-right corner bl float: radius for bottom-left corner
Returns	void
