I need help modifying my Bump proc so that it gives the object's shooter +10 Experience. Here is all the code that has relevance.

proc
    fireprojectile(Type, mob/Who)
        /*
            Type = the type of projectile
            Who = who fired/threw the projectile
        */
        var/obj/projectile/S = new Type(Who.loc)    // make a new projectile where the mob is
        if(!istype(S,/obj/projectile))  // make sure they are
            world.log << "Invalid projectile:[Type]"
            return
        S.dir = Who.dir // projectile faces same dir as the mob
        S.who = Who
        S.shooter = S.who
        S.missileloop()



obj
    projectile
        density = 1
        layer = FLY_LAYER
        var
            mob/who // the mob that fires the projectile
            damage = 1   // how much damage the projectile causes
            mrange = 10   // how far the projectile can go
            delay = 0    // number of ticks between movements




        proc
            missileloop()
                walk(src,dir, 0) // T = space the
                if(--mrange > 0) // decriment range
                    spawn(delay) missileloop()
                else
                    endmissile()

            endmissile()
                /* This proc is called when the missile stops moving.
                    Override it for missiles that have special effects
                    like explosions or leaving items where they land.
                */
                del(src)


        Bump(O)
            if(ismob(O))
                // damage proc
                O:HP -= src.damage
                O:DeathCheck()
            endmissile()    // we hit something, so the missile stops

obj
    var
        shooter

What you need to do is give DeathCheck() an argument that says who the (potential) killer is, and use that information to add the experience from there. Your Bump() proc should then pass along the owner of the projectile as an argument to DeathCheck().

Is this what you meant, Lummox?

Bump(O)
    if(ismob(O))
          // damage proc
          O:HP -= src.damage
          O:DeathCheck(src)
          endmissile()  // we hit something, so the missile stops

mob/proc/DeathCheck(P)
    if(src.HP<=0)
        if(!key)
            del src
        else
            
            var/X=rand(1,world.maxx)
            var/Y=rand(1,world.maxy)
            var/Z=rand(1,world.maxz)
            usr.Move(locate(X,Y,Z))
            world << "[src] was killed!"
            src.HP = 100
            Ammunition = rand(1,300)
            Grenades = rand(1,3)
            LAWs = rand(1,2)
            P:Experience += 10

Bump(mob/O)//Wasn't defined correctly
    if(ismob(O))
          // damage proc
          O.HP -= src.damage //EVIL COLONS!
          O.DeathCheck(src)
          endmissile()  // we hit something, so the missile stops
 
 mob/proc/DeathCheck(P) //Not defined correctly!
    if(src.HP<=0)
        if(!key)
            del src
        else
            
            var/X=rand(1,world.maxx)
            var/Y=rand(1,world.maxy)
            var/Z=rand(1,world.maxz)
            usr.Move(locate(X,Y,Z))
            world << "[src] was killed!"
            src.HP = 100
            Ammunition = rand(1,300)
            Grenades = rand(1,3)
            LAWs = rand(1,2)
            P:Experience += 10//Colons!


Agghhh! Evil colons choking me!

Worlds: Looks like a job for Superworlds!

I've done the code as it should be (roughly).

No, because you did several things wrong.

First, you're still using usr in DeathCheck(). Totally wrong. Never ever ever do that.

Second, you called DeathCheck() with src, which is the projectile, not the porjectile's owner.

Third: Give P a type like mob/P, so you don't have to use a colon.

I'm not 100% sure what you meant about the second problem (src is the projectile, not the projectile's owner.) I think the projectile's owner (using the system I set up) would, in this case, be src.owner, which I have pointing to src.shooter. How can I make that a bit less cumbersome?

You're correct. The correct thing to call DeathCheck() with would be src.shooter.

How can I make that a bit less cumbersome?

The best way to handle projectiles is to handle all initialization of the projectile in New(), not in the verb where you fire it. Pass a second argument to new() saying who fired, and then rewrite New() like this:
obj/projectile
  var/mob/owner      // or shooter, in your case
  var/range = world.view

  New(newloc, mob/M)
    owner = M
    if(M) walk(src, M.dir, 0)    // start moving
    spawn(range) del(src)     // limited range

I am not sure exactly how this is. However, here's how I did this. I made DeathCheck accept 2 arguments. One is mob/P, one is mob/S. On Bump, mob/P is defined as src.shooter, mob/S is O. The rest is the same.

The mob/S bit is useless. The O in your Bump() is the thing that was bumped into, which is the mob whose DeathCheck() proc is called, so S==src in DeathCheck(). Therefore you don't need it; get rid of it.

It may be useful however to also tell DeathCheck() something about the weapon, so passing src (from Bump()) as a second argument (but not the first) might not be a bad idea.
