Code:
//The Player
mob
    var/projectile=/mob //This will be used to determine what they will shoot
    icon='player.dmi'
    Player
        //Test to see if the Fire() proc works
        verb
            Test()
                src.Fire()


//The Shooting
mob
    proc
        Fire()
            world<<"Rawr!"
            var/mob/P=src.projectile
            new P(src.loc)
            P.dir=src.dir
            while(src.projectile)
                step(P,P.dir)
                var/turf/T=P.loc
                if(T.density==1)
                    //Place Damage To Turfs Code here later
                    del P
                    world<<"[P] hit [T]!"
                    break
                //If there is a mob in T
                for(var/mob/M as mob in T)
                    if(M==src)
                        continue
                    //Place damage to players here
                    del P
                sleep(5)


Problem description:

Whenever I fire, it spawns the projectile P just fine, but it won't let P step. Heres the error it gives:

runtime error: Cannot modify /mob.dir.
proc name: Fire (/mob/proc/Fire)
usr: Dead_Demon (/mob/Player)
src: Dead_Demon (/mob/Player)
call stack:
Dead_Demon (/mob/Player): Fire()
Dead_Demon (/mob/Player): Test()

In short, the problem is as the error tells you, P contains a type path, '/mob', and and not an object, therefore you can't access it's variables.

To expand on what Kaioken said, you're making a new 'p', sure enough, but you're not setting the 'p' variable /to/ it, so it's still a typepath.

var/mob/P=src.projectile
new P(src.loc)


should be:

var/mob/p=new projectile(loc)


(You can leave out src)
