ladders
    parent_type = /obj
    icon = 'objects.dmi'
    up
        icon_state = "ladderu"
        Entered(mob/M)
            if(ismob(M)&&M.key)
                M.loc = locate(M.x,M.y,M.z--)


Won't work. Nothing happens, at all. Even if I remove the if(ismob) part.

It's quite simple really - the "Enter(), Entered(), Exit(), Exited()" procs are only called when you "Enter()/Exit()" their contents through "Move()". So, even though you're walking over the object, you're not actually in its contents - you're in the turfs contents.

So... what would I do to do that? Modify Move()? Or make it a turf?

You need to work with turf/Entered(), not obj/Entered(), to achieve the result you want. One solution is to check each obj in the turf for some special trigger, like so:
obj
  proc/StepAction(atom/movable/A)
    // override for any special objects

turf
  Entered(atom/movable/A)
    for(var/obj/O in src)
      O.StepAction(A)

Incidentally doing M.z-- and setting M.loc is going to be counterproductive. locate(M.x,M.y,M.z--) returns the current location, and M.z-- will move M for you; then M.loc is being reset to the old location. If this was --M.z instead, it would be redundant, but it would work. The best of both however is M.z-1.

Thanks, Lummox. :)
That did the trick.
[Edit] Another question now...
                    for(var/mining/wall/W in view(5))
                        del(W)
                    M.loc = locate(loc1,loc2,loc3)

It all works, except it doesn't delete the stuff on the floor below(the wall).
Otherwise, it works.
