Help with problem

[CronoSama]

I made an item called a smoke bomb which teleports you to the entrance of the dungeon or in this case I am using it for to escape from jail.But if I made it so you can buy them and he used a smoke bomb wouldn't it teleport him to what I set the first one to go to. Example Way later in the game you use the smoke bomb and you teleport out of jail(whereever I set that to), or should I make smoke bombs teleport you to the most central point in the map like this:
Second Dungeon
|
First Dungeon-----------0(Central point)----Third Dungeon
|
Fourth Dungeon

And do that so its less work , but the more work the better the game will be, so how would I do that, btw I am not new to RPGMaker I just had to delete it a while back due to lack of space on my Hard drive but for christmas I got a new Hardrive so I started on a new RPG to make, so help if you can

brain scrambled im not sure what u mean a better explination is needed

i think i know what u mean. u probably need some co-ordinate variables. make it so that when you enter a dungeon, the game sets a "memory place" to variables. then, when you use the item, make it "Go to memory place", stated in the variables. when the person exits, make the game clear those variables so the bomb won't work outside.
