Remove inventory condition after it has been done?

[Ghostlady]

I am using first person for the game.  If an inventory key was needed to enter room 2 from room 1, and that was done, and they are back in room 1, how do I remove the inventory condition so they can now reenter room 2 without the inventory?

You could set a global variable the first time ,a nd then check for that before the invetory condition
