rect( x0, y0, x1, y1, [col] )
- Draws an empty rectangle shape.
- x0
-
- The x coordinate of the upper left corner.
- y0
-
- The y coordinate of the upper left corner.
- x1
-
- The x coordinate of the lower right corner.
- y1
-
- The y coordinate of the lower right corner.
- col
-
- The color of the rectangle border. If omitted, the color from the draw state is used.
This draws a rectangle shape parallel to the screen borders.
It's important to note that the coordinates are inclusive, which is to say PICO-8 will render pixels at the right and bottom coords. In many APIs, x1 and y1 would be the first pixels which are not drawn, but on PICO-8, they are the last pixels which are drawn.
Examples
-- draw a border around the whole screen
rect(0, 0, 127, 127, 1)
-- draw a border inset by 16 pixels
rect(16, 16, 111, 111, 1)
-- draw three empty white rectangles at random locations and sizes
color(7)
for x=1,3 do
rect(rnd(128), rnd(128), rnd(128), rnd(128))
end
