how do i make an area that allows the user to be moved to a different area but not a mob. the code i have...

turf/Enter_Forest
icon = 'forest.dmi'
Entered(usr/M)
usr.loc = locate(1,99,7)
usr<<"it looks like an empty forest.."
..()



moves the mob and user. if a mob happens to walk over it, it moves the mob to that area. is there a way i can make it so mobs aren't moved but the user is?

When any character logs in you can give them a certain var that NPCs dont have.
Then you can check to see if the mob has that var and if they do let them through
area
Place
Enter(mob/M)
if(M.var>=1)
usr.loc=locate(1,1,1)
usr<<"Hey look you moved."
else
return ..()

You can check to see if a mob is owned by a player by checking to see if the variable "key" is not null.

turf/Enter_Forest
icon = 'forest.dmi'
Entered(mob/M)
if(M.key)
M.loc = locate(1,99,7)
M << "it looks like an empty forest.."
else
..()

Some points to note: It's not safe to reference "usr" here at all. You've already declared M as the pointer to the mob in question, so use that variable.

Another way to test if a mob is owned by a player is the test if(M.client). This will return true if a client is currently connected to the mob, but will fail if that person lags out at that moment.

By the way, "usr" is usually a mob too. Mob does not necessarily mean NPC.

You're misusing usr here. Remember, the player is also a mob. What you really want is for player mobs to be moved, but monster mobs to stay put. usr is always the last player to use a verb; this might actually work in your code, at least in single-player mode, but it's really bad form. The rule of thumb is: Never use usr, except in a verb.

Another problem is this:
Entered(usr/M)

usr is not a type path. That shouldn't even work at all.
The Entered() proc actually will take any atom/movable as an argument. Therefore, your proc should look like this:
Entered(atom/movable/A)
  if(ismob(A))
    var/mob/M=A
    if(M.client)
      ...  // do the teleport
      return
  ..()

Now, A can be an obj or a mob (because it's atom/movable, the base type for both). If it's an obj, it doesn't pass the first if() check. If it's a mob but has no client (that is, it's not a player), it doesn't pass the second if() check. If it passes both, it's a player, so then you can teleport them.
