im makin a program where i repetidly need to check to see if a lot off bullet sprites have hit chareter sprites, i havent evan got that many enemys yet and its already lagging, is there a more efficiant way to check every sprite against every other enemy?

example incase u dont understant coz that sounds a bit dodgy:

there could be up to:
1 player
30 his shots
i special attack

10 enemys
15 enemy shots

every player bullet needs to be checked on every enemy
every enemy bullet needs to be checked on player
player needs to be checked on enemy
if possible, bullets against bullets to

cheers

its ight i found it out:

insted of saying:

for bullet = 1 to num of shots
for c = 1 to numofaliens
if sprite collision(bullet, c)
``do stuff
endif
next c
next bullet

i use the very simple code
if sprite collision(bullet, 0)
in the move bullet command
