I've been working all weekend to come up with a formula for this, and I
realize now I probably should have gone ahead with that third semester of
calculus.
Here's the problem. I have one main sprite that floats around the screen. I
also have 44 other sprites scattered around the screen, each confined to an
area about 100 x 100.
I want the floating sprite to exert sort of a planetary gravity effect on
the other sprites. As the floating sprite approaches a fixed sprite, that
fixed sprite should start moving towards the floating sprite, but stay
within its 100 x 100 rectangle. Ideally, the closer the floating sprite
gets, the more the stationary sprite should be attracted--i.e., the faster
it should move.
The reverse should happen, too--as the floating sprite moves away, the
fixed sprites should follow, but slower and slower as the floater moves
farther away. At some point--probably when the floater is about 200 pixels
away--the fixed sprite will drift back to its original location (that
part's already done).
So, does somebody have a formula to do this? If it's in lingo form, great.
If not, I can convert it easily.
Cordially,
