I use multiverse core and when changing the world I need to save the position before the player teleports, for example the player is in world1 use the command to world2 and before teleporting save his last position in world1, how to do it?

Code (Text):

1. on player world change:
2.     wait 10 tick
3.     if player has permission "op":
4.         set {LastLocation.%player%} to location of player
5.         stop
6.  
7. command /backtolastlocation:
8.     permission: op
9.     trigger:
10.         if world is "lobby":
11.             teleport player to {LastLocation.%player%}
12.         else:
13.             message "&c Nejsi v lobby"

 

I don't understand how to use it, teleportation works for me but it teleports me back to the spawnlobby of the world "zkouska" and not to the last location of the player
my new code-

Code (Text):

1.  
2. on player world change:
3. #    if player has permission "op":
4.     if event-world is "zkouska":
5.         set {LastLocation::%player%::loc} to event-location
6.         stop
7.  
8. command /backtosurvival:
9.     permission: op
10.     trigger:
11.         if world is "lobby":
12.             teleport player to {LastLocation::%player%::loc}
13.         else:
14.             message "&c Nejsi v lobby"
