Draws a line (a direct path between two points) to the screen. The version of line() with four parameters draws the line in 2D. To color a line, use the stroke() function. A line cannot be filled, therefore the fill() function will not affect the color of a line. 2D lines are drawn with a width of one pixel by default, but this can be changed with the strokeWeight() function.
