PICO-8 provides two simple ways to draw rectangles: RECT() and RECTFILL(). RECT() draws an empty rectangle with a 1 pixel wide border, whereas RECTFILL() draws a filled rectangle. Each function accepts a X and Y position for the top-left and bottom-right corners and a color.

RED=8

X1=60
Y1=60
X2=68
Y2=68

-- DRAWS AN EMPTY RED RECTANGLE IN THE CENTER OF THE SCREEN
RECT(X1,Y1,X2,Y2,RED)

-- DRAWS A FILLED RED RECTANGLE IN THE CENTER OF THE SCREEN
RECTFILL(X1,Y1,X2,Y2,RED)

If you’re drawing a lot of shapes with the same color, you may omit the color parameter by setting the current color with the COLOR() function.

RED=8

FUNCTION _DRAW()
    COLOR(RED)
    RECTFILL( 0, 0,10,10)
    RECTFILL(20,20,30,30)
    RECTFILL(40,40,50,50)
