Store Location

i want a code so if u enter a turf u r transported to another place and when u leave that plae thru a turf u appear where u left from.

the problem is that u can enter this place from dif locations on the map so i cant just ask it to transport u to a certain place when u leave coz u wouldnt necessarily appear in the place u went in from.

i thought of using a variable that stores ur location just before u enter the turf...

turf
    enterplace
        icon = 'place.bmp'
        Enter()
            var/storeloc = locate(usr.x,usr.y,usr.z)
            usr.loc=locate(10,2,2)

    leaveplace
        icon = 'turfs.dmi'
        icon_state = "leave"
        Enter()
            usr.loc = storeloc

but i get an error message saying i havent defined storeloc and i get a warning saying that i have defined storeloc but i havent used it

any help or suggestions?

Oh and it'll be great if u can help me with one more code problem:

obj/Gravitronfour
    name = "Gravitron Four"
    icon = 'turfs.dmi'
    icon_state = "gravity"
    density = 1
    verb
        Gravity()
            set category = "Training"
            set src in oview(2)
            var/howmuch = input("How much Gravity?") as num|null
            if(howmuch < 0)
                usr << "<b>Thats not possible."
            if(howmuch == 1||howmuch == 0)
                usr.grav = 0
                usr << "<b>You turn off the gravity...."
            if(howmuch > 1 && howmuch <= 150000)
                if(usr.grav >= 1)
                    usr << "<b>Please set the gravity to 0."
                if(usr.grav == 0||usr.grav == null)
                    usr << "<b>You hear the machine turn on..."

                usr.maxpowerlevel += 1
            else
                return

thats the code i use for gravity from gravitrons. I know this is straight from zeta but i promise i'm not using this for a zeta rip...i just want to learn so i can ake my own original game(non-dbz)...this is just a test project

The problem with that is that u can stand in the same spot and the gravity keeps on working, is there a way to make it so u HAVE to walk around in order for the gravity to work and if u dont then it doesnt have any affect. And it'll be great if u can make it so the effect of the gravitron only works if the gravitron is near u.

Thanks for any help, i need more help with this than the other one btw.

As much as it pained me to wade through that, here goes. The reason you are having a problem here, is you are not keeping track of your variables scope. When you declare a variable within a procedure, that variable is only available within that procedure. When you attempt to access the 'storeloc' var within the /turf/leaveplace/Enter() proc, the program can't find a storeloc variable within the current scope, therefore, it gives you the undefined var error.

When you declare the storeloc var within the /turf/enterplace/Enter() proc, but don't use it anywhere within the proc, the compiler gives you the 'defined but didn't use' warning.

You really need to declare this var as a mob var. When a player enters an 'enterplace', set their storeloc var to their current location. When they enter the 'leaveplace', set their loc to the previously saved storeloc.

// Give the mob a 'storeloc' var where you will store
// their previous location.
mob
  var
    turf/storeloc

//  Within the enter/leaveplace's Enter() proc, use the 
//  provided atom/movable/O var rather than 'usr', to 
//  prevent Lummox from beating you.  :)  'usr' is not
//  always going to be what you expect it to be, but
//  atom/movable/O will ALWAYS be the atom attempting
//  to enter the turf.

//  Simply use ismob() to check if the atom entering
//  is a mob.  If it is, set up a temorary mob var, set 
//  that var to O, and either set the storeloc var, or
//  move them back to storeloc.

turf
  enterplace
    Enter(atom/movable/O)
      if(ismob(O))
        var/mob/M = O
        M.storeloc = M.loc
        M.loc = locate(10,2,2)
      ..()

  leaveplace
    Enter(atom/movable/O)
      if(ismob(O))
        var/mob/M = O
        M.loc = M.storeloc
      ..()

Garthor	Your problem is two-fold. First, you are using usr in a proc. Namely, you're using it in Enter(), which is EXTREMELY wrong. Second, you are using Enter() when you should be using Entered().
