line()

Description
Draws a line (a direct path between two points) to the screen. To color a line, use the stroke() function. A line cannot be filled, therefore the fill() method will not affect the color of a line.

Syntax


line(x1, y1, x2, y2)


Parameters
x1 – x-coordinate of the first point, 0 to 319
y1 – y-coordinate of the first point, 0 to 239
x2 – x-coordinate of the second point, 0 to 319
y2 – y-coordinate of the second point, 0 to 239

Returns
none
