I am trying to make a (semi-) Starcraft game that works perfectly so far. But there's only one problem ... How do I make the spacecrafts shoot in the direction that they are facing??? This plagues up the entire game... when i tried myriad ways, all failed... Plz Help!
THANX A LOT!!!

It depends on the viewpoint. I assuume you used an isomatric setup like in starcraft?

well, if you know what angle they are facing, then shooting is easy.

instead of normal bullets that goes straight up like this:

code:
loop
    y += 5
    drawfilloval (x, y, 5, 5, red)
    cls
end loop


do something like this:

code:
loop
    y += sind (angle)
    x += cosd (angle)
    drawfilloval (x, y, 5, 5, red)
    cls
end loop


where the variable angle is the angle they are facing.
