Custom projectiles

[DustyPorViva]

Well, it seems shoot() just won't cover the requirements I need it to. I projectiles to travel over some walls, and of course, not over others.
So it seems I just have to do some custom projectiles.

So, question is, what is the best way to do that? I've figured out two possible ways. putnpc2(), and showimg().

putnpc2() would have an obvious delay from being created, and would probably best be done serverside. I could imagine the lag this would cause.

showimg() would have no delays on the clientside, but to other players there would be a delay depending on your connection(I think... could be the other way around). Either way, it's superior for clientside effects, not so much for serverside.

Which do you think I should do?
