Hi, I hope you don`t mind me jumping in, but from the video this is an excellent example.
I have a play maker template where you can choose if the player needs a key to open the door.
The need key bool can be set within the inspector to false or true.
True "you need a key to access"
False "no key needed"
To be honest I don`t know if you can share templates.
let me know if this kind of help would be useful.
I am not around much lately, but will check on a reply when I can.
