Entered() and objs

Does Entered() work with objs? My friend told me it did, but when i tried it it didn't. If it doesn't, or if i jsut don't know how to use it, is there an alternate way of checking to see if a person walks over an obj?

It doesn't. What you can do is this:

turf
    Entered(mob/M)
        if(ismob(M))
            if(locate(/obj/blah) in src)  //if there's an object on the turf (in the turf's contents)
                //stuff
        return..()

So then, lets say i have a door code like this 
obj/door
   density = 1
   Click()
     density = 0

it order to close it, would this work? 
turf
   Entered(mob/M)
     if(ismob(M))
        var/obj/door/O
        if(locate(O) in src)
           O.density = 1

would that work?
thanks

You could try it before asking, the best way to learn is through trial and error.

Entered() does work with objs, but not in the way you thought it would. It does not check to see if a person walked over it, because what the person's mob entered was the turf it's on, not the obj itself.

The way Entered() works for all atoms--turfs, objs, mobs, and areas--is to be called whenever something uses Move() to enter its contents list. When you walk onto a turf with another obj, obj.Entered() is not called because you didn't get into the obj; you stepped onto the turf. However if the obj was some kind of treasure chest and you could climb in, then Entered() would be called for it.
obj/treasurechest
  verb/Get_In()
    set src in oview(1)
    usr.Move(src)

  Enter(atom/movable/A)
    .=..()
    if(!.)
      A << "There's no room in [src]."
      return 0

  Entered(atom/movable/A)
    if(ismob(A))
      A << "It's cramped in here."
I hope that clears things up.

Ah, I forgot about that method, thanks for the reminder.

Isn't that <code>return 0</code> redundant?

Probably the best way to handle this is to create two new procs, walkOver() and walkOff(), like this:
atom/movable/proc/walkOn(atom/movable/A)
atom/movable/proc/walkOff(atom/movable/A)

turf
  Entered(atom/movable/A)
    for(var/atom/movable/M in (src.contents - A))
      M.walkOn(A)
    ..()
  Exited(atom/movable/A)
    for(var/atom/movable/M in (src.contents))
      M.walkOff(A)
    ..()
obj
  Door
    walkOff(atom/movable/A)
      if(loc.contents.len == 1) //If it's the only thing there
        src.Close()

  Landmine
    WalkOn(atom/movable/A)
      view() << "KABLOOIE!"
      del(A)

obj
    stairs_A
        icon = 'stairsup.dmi'
        Entered(mob/M as mob)
            if(!M.client)
                return
            else
                M.movable = 0
                M.Fade_Out()
                M<<sound("stairs.wav")
                M.loc = locate(M.x,M.y,M.z+1)
                sleep(10)
                M.Fade_In()
                M.movable = 1

so using that, how can i change the stairs to an object?
because for some reason i couldnt call the mobs variables.

I tried this
obj
    stairs_A
        icon = 'stairsup.dmi'
        WalkOn(atom/movable/A)
            if(ismob(A))
                if(!A.client)
                else
                    A.movable = 0
                    A.Fade_Out()
                    A<<sound("stairs.wav")
                    A.loc = locate(A.x,A.y,A.z+1)
                    sleep(10)
                    A.Fade_In()
                    A.movable = 1

but that didnt work. Please help.

Did you include the Entered() and Exited() changes I wrote for your turfs?

What i have now, should work, yet it doesn't.
obj/door
    icon = 'turfs.dmi'
    var/orig    
    jaildoor
        icon_state = "jaildoor"
        orig = "jaildoor"
        density = 1
        verb/action()
            set src in oview(1)
            set hidden = 1
            if(src in get_step(usr,usr.dir))
                src.density = 0
                src.icon_state = "blank"
turf/Entered(mob/M)
    if(ismob(M))
        var/obj/door/O
        if(locate(O) in src)
            O.density = 1
            O.icon_state = O.orig

can someone help?
thanks

Okay, first of all, it's walkOn, not WalkOn. Second, after you do an ismob() check, use var/mob/M = A, and then use M.

if(ismob(A))
var/mob/M = A
if(M.client)

It's not a bad habit, especially if you work in other languages that don't default to a return value of zero. The Vignette TCL interpreter I must suffer at work comes to mind.
