TechMage will know for sure on this one.

I am also toying with the idea of using Pythagoras therom, as I think the above hit detection would do strange things at wierd angles,

DIST=((XS-XP)^2+(YS-YP)^2)^0.5
IF DIST<15 THEN
collision!
ELSE { move again }

DIST=distance from object using pythagoras theorem
XS,YS=shot coords, XP,YP=Enemy coords.
15 = size of object

Since that uses the radius of the object I reckon that would be angle independant.

Would that use to much clock cycles?

Yes, square-rooting is fairly clock-intensive. If your game runs fast already, though, there's nothing to worry about.

Thanks guys for your great responses!

Dan, good advice on that square root, never thought of that DOH!

Thanks again guys that was great advice.

Just toying with evb atm, to get the fram work of the game going then move to evc for the real deal

Well speak of the devil. ASpriteCE is now freeware. You can get it at

I payed 30 bucks for this control just a few months ago. If you're making eVB games, this is a must have.
