say i have a box

tlx = x - scale
tly = y + scale

trx = x + scale
try = y - scale

brx = x + scale
bry = y + scale

blx = x - scale
bly = y + scale

and i wanna do collision detection of the four edges
hitting the other four edges

like boxtop1 = boxbottom2
boxbotttom1 = boxtop2
boxright1 = boxleft2
boxleft1 = boxright2

how can this be done????

Any help would be real nice because the code I worte is not working right.

Is there a reason you can't use some existing collision code/dll's out there? Collision is completely sorted there's no real need to re-write it...

I'd suggest taking a look at "Sparky's collision" dll as it is very accurate and fast but there are a few options to choose from here:

(just type "massive collision" in the search bar at the bottom if you're ever looking for it again!)
