DRAW sequence m option

[CharlieJV]

Can someone please elaborate a bit on the m x,y (and its related +/- options)  in the draw command? It doesn't get a mention (that I can find) in the Help file, and the Wiki one is pretty unclear. How is it fitted into a draw string, and does it need parentheses, or commas etc? 

Sample code if you want to play around:

Code: (Select All)

screen _newimage(200, 200, 12)

xf = 150
yf = 150

do
x = int(rnd*200)
y = int(rnd*200)
draw "B M" + str$(x) + "," + str$(y)
draw "d15 r15 u15 l15 m " + str$(xf) + "," + str$(yf)
_display
_delay 1.25
loop

And now, for the giggles, try the same program with a little tweak so that the second M command is a relative coordinate instead of a fixed coordinate:

Code: (Select All)

screen _newimage(200, 200, 12)

xf = 150
yf = 150

do
x = int(rnd*200)
y = int(rnd*200)
draw "B M" + str$(x) + "," + str$(y)
draw "d15 r15 u15 l15 m -" + str$(xf) + ",-" + str$(yf)
_display
_delay 1.25
loop
