So I have this game where several doors need a key card to open. But not just possessing the key card but actually swiping it. Not sure how to do this, would it a verb and the item? Also there will be several doors that require the key card, so it need to use the card to open a specific door at a time. Also some of the doors are in the same room, so just coding it so using the key card in a specific room, would open all the doors that require in in the room.

Maybe something like this (with verbs and a fake key):

Each door has a "keycard" object attribute set to the appropriate keycard.

I think I’m X2 I simply used the “use other object on this” script. For the correct key I would obviously unlock/open the door. For incorrect keys I used the else if script here and commented ‘that didn’t seem to work on this door.’ For the else part of the script, I simply scripted a comment like ‘that obviously won’t work.’

If you don’t like the use this bit, simply add a verb like ‘swipe’ to the door/keypad and run the same scripts.

I’m sure KVs code works fine too but just in case you like the “dumbed down” version like me. :)
