Requires the library mod Collective. 

   This mod is part of The Vanilla Experience.
Automatic Doors is a minimalistic configurable mod which automatically opens doors around the player and closes them with a delay. The doors will only be closed if the player isn't near after opening. By default iron doors will also be opened, but you may change that in the config.


Configurable: ( how do I configure? )
doorOpenTime (default = 2500, min 0, max 10000): The time in ms the door should stay open.
shouldOpenIronDoors (default = true): When enabled, iron doors will also be opened automatically.
preventOpeningOnSneak (default = true): When enabled, doors won't be opened automatically when the player is sneaking.
