on My new game im finaly making buildings and im wondering how to make portals for them to go to a new map when they walk in the door.

if someone can give me a tip without giving out the whole code.

iv tried using loc on turfs to make them spawn somwhere else but it didnt work.

To tell when someone has walked on a turf, you can override the turf/Entered() proc.

turf/portal/Entered(atom/movable/A)
  if(istype(A, /mob)) // make sure that what walked on me is a mob
    var/mob/M = A

    DoStuffWith(M)


You can move stuff around by using locate() to find a target turf to send the object to, and then set the object's 'loc' variable to be that location.

Look up locate and loc in the DM Reference.
If you don't know how to do something, the DM Reference is your best buddy.

M.loc=locate(#,#,#) Locate is like the first thing in the dm guide.

Well, you clearly don't know the syntax of the language, so you're going to need to read some tutorials.

Might use this.
turf
    Portal
        density = 0
        icon = 'Portal.dmi'
        Enter(A)
            if(ismob(A))
                var/mob/M = A
                if(M.client)
                    M.loc = locate(199,3,4)
            else
                if(istype(A,/obj/)) del(A)


This should help you out.

Enter is the wrong event hook to use when you want to process some action. It should be used to determine accessibility of movement. What you want is Entered.
And a hard-coded locate call is rather ugly when you want to change the map later on. Why not use a tag instead?

Why do people do Enter(ed)(A) then go through the hassle of doing var/mob/M = A (especially when you confirmed only mobs should be able to step on it)? As far as I know it's as efficient either way it's just a bit of a quirk to me.

Because it's technically correct. Writing Entered(var/mob/M) does not filter out non-mobs.

In response to Garthor
But neither does var/mob/M = A.

In response to Moonlight Memento
It is because some non-mobs can step on it, so we do not want to treat them as mobs until we have confirmed that they are indeed mobs.

In the example, if a mob enters the turf, then it will teleport. If an object does (such as an attack) it gets deleted.

Where did I say it did? That's what if(ismob(A)) is for.

In response to Garthor
 
turf/grass/Entered(mob/M)
    if(ismob(M)) return 1
    else return 0

That's what I meant. There's no need for a second variable if only mobs are permitted entry.

What if it is on a different map? lets say you have 3 maps, one is the main map, on is a shop, and one is a house, how would you make the portal, to go to the shop map?

When the game is compiled, it fuses all of the maps into a giant map, and just increases the z layer.

In response to Moonlight Memento
Regardless, it's technically incorrect as, until the ismob(M) line, you don't know that M is a mob.

Then you'd use tags instead of absolute coordinates.

Ah, so basically just put like

mob/pc
  login()
    ..()
turf/store_door
  verb(m as usr)
    Enter(m)
      loc = locate(1,1,2

Like that?
