I have a sort of bullet sprite that travells in a straight
line, but im unsure of how to detect the collision between another
sprite, and if there are any sprites nearby. So is there any way to
'get' the sprites in a rect or preferably a radius?
You get the best accuracy if test 2 bitmap sprites using
matte ink using
the intersect function, you could have a circle bitmap in a
channel which you hae hidden, perhaps by setting blend to 0,
cide than can position and perhaps scale this radius test
sprite in the
are of interest.
One has to test for intersections sprite by sprite
on checkIntersects circleSprite
intersectList = 
repeat with i = 6 to 20 -- range of interest
if sprite i intersects circleSprite then apppend
