This code generates the mission okay. But when I "get" an item that is on the "parkinglot" it doesn't make it unoccupied and gives me a bad var error.


turf
    parkinglot
    var/occupied = 0

obj/missions
    icon = 'items.dmi'
    verb/get()
        set src in oview(1)
        src.loc = usr
        src.loc.occupied = 0//bad var here
            //also tried src.loc.loc(back when parking lot as an area
        verb/drop()
        set src in usr
        src.loc = usr.loc
    note
        icon_state = "note"


Thanks for reading

src.loc = usr
src.loc.occupied = 0
I think it might be because you're setting it's location to usr' contents, then checking it's location. Try switching those two lines around.

The problem is that locs are not always turfs, they can be any atom, or even null. Test to make sure it is a turf, and either use a turf alias or the Unspeakable Alternative Which Shall Not Be Named Here.

I'm no expert on the syntax, but it looks to me as though if src.loc = usr, then src.loc.occupied is equivalent to usr.occupied, and occupied isn't a property of mob. I may be wrong. I'm a major newbie here. But why don't you just set usr.loc.occupied = 0 instead?

I use a little proc I wrote for myself called my_turf that returns the turf of any object. It's very useful!

I don't have it in front of me, but it's something like:

proc/my_turf(atom/movable/what)
  var
    this_loc = what.loc

  while(this_loc && !(isturf(this_loc))
    this_loc = this_loc.loc

  return this_loc

turf
parkinglot
var/occupied = 0
proc/parkinglotmission()
var/turf/parkinglot/X
var/obj/missions/note/note
note = /obj/missions/note
for(X in world)
if(X.occupied == 0)
X.occupied = 1
new note(X)
break

This works fine and all, but you can tell where the note is going. Example:
X = parking lot
N = note


XXXXXX
XXXXXX
XXXXXX
XXXXXX
XXXXXX

That is the parking lot. When a note is created, it goes in order. Example:

I call the proc once, this is what the map looks like.

XXXXXX
XXXXXX
XXXXXX
XXXXXX
NXXXXX

I call it again, this is what the map looks like.


XXXXXX
XXXXXX
XXXXXX
XXXXXX
NNXXXX

i call it again, this is what the map lookslike.


XXXXXX
XXXXXX
XXXXXX
XXXXXX
NNNXXX

and so on and so on.


How could I stop it from spawning in order?

Add all the possible locations where it could be placed to a list, then pick randomly from the list:

proc/note_mission
   var/list/locations = list()
   for(var/turf/T in world)
      locations += T
   var/create_at = pick(T)
   // create it at T

Ahhh thanks ;) And if I ever lose my files again or somebody is searching the forums 999 days from now and needs something like this:

proc/parkinglotmission()    
    var/turf/parkinglot/X
    var/obj/missions/note/note
    note = /obj/missions/note
    var/list/locations = list()
    for(var/turf/parkinglot/T in world)
        locations += T
    for(X in world)
        if(X.occupied == 0)
            X.occupied = 1
            new note(pick(locations))
            break


I know I would find this useful. Sometimes people solve problems off the forums ;)
