Each door token contains its own vision blocking and macros.
Here is what they look like.
v1.3.3_compatible can be operated by players and should be used on earlier versions of MT
v1.3.3 doors do more but will only work on MT 1.7+, may not be operable by players
v1.4.2 fancier, with more tricks, but can not be operated by players until MT 1.8.
There is an issue where Fog of War is reset when opening doors due to my misunderstanding of how exposePCOnlyArea() works. If you experience this, download the current versions from the links below.
The doors are set up for use in different languages but there is only one language until people contribute translations.
Smart Doors can be operate as Swing doors or Sliding doors and have settings that allow you to control the direction of swing and the opening arc.
Smart Doors can be locked and unlocked, peeked through, partially opened, or linked in pairs to act as a set of double doors.
Here is an example of a Smart Door's macros:
Smart_Doors_v1.4.2.zip MT 1.8
Smart_Doors_1.3.3.zip MT 1.7+ (GM only)
Smart_Doors_1.3.3_compatible.zip MT <1.7 <-- most reliable
