Doorways

Saloon doors now swing both ways, and close by themselves

They hang on double-acting spring hinges. That is one mechanism, and it changes three things at once:

• They swing to either side. Push a saloon door and it goes away from you, whichever side you are standing on. Every other door in the mod still opens one way.
• They shut on their own, about two seconds after you walk through. If something is standing in the doorway the spring keeps pressing and closes as soon as it moves.
• They ignore redstone. A spring hinge has no latch, so there is no position a signal could hold it in. A powered saloon door simply stays shut.

A blocked door refuses rather than swinging the other way. A door that occasionally opens towards you, for reasons you cannot see, is worse than one that will not budge.

Recipe

Saloon doors now take two iron nuggets alongside the planks, for the springs. The nuggets sit either side of the hinge:
