Find key in this map, use it in the other.

yes you can. You just add the script in the .hps file of DarkLobbyRoom

Thanks bro, so the game recognizes the key even if I picked it up from another room.

When you use a key on a door, what other item that you put in the script, it only checks for the name of the entities you put in the script.
Where you got the entity from, the game dosen't give a f*** about

You've made yourself clear Thanks again.
