Possible to repeat script With.._

[Amnesiaplayer]

Is it possible to repeat something, not the WHOLE script but just.. like on func thing, because i have a Cannon, and i want to let it "Shoot" a cannon ball, with propforce etc, and then like, Particle infront of it, so it looks liek it's actually shooting (help here to, is there a particle that looks like a mini explosion?! to use it on the cannon?) so, can i repeat them ALL, because my point is,
you're doing something, and then fell from a high thing, then like, sleep... and then wake up there but you're actually dreaming, and that's a dream palce, where there are 2 castles, fighting each other, with cannons, like you wake up, and see cannon's shooting!
i Actually wanted fog in this, but AMNESIA'S FOG IS *@#%&#$*^
but yeah, so i want to make it repeat, and can i move the player? like make a script, if you can, it owuld be very cool... this is liek a dream, to remember, what happened to you, in World War II...
