@malice:
if you create lets say, 100 instances of type 'bullet', and you use 3 seperate loops then you are looping 300 times...while if you do all the movement/checking for collisions/out of range checking in just 1 loop you only have to loop through 100 bullets instead of 300 which saves you a lot of calculation time.
