Door Closer
This mods makes doors close on their own when placed above an iron or gold block.
About this Mod
This mod requires Fabric API.
This mod makes it so any door placed above an iron or gold block auto-closes after a set amount of ticks depending on the block underneath them (see below).
It only affects doors opened by the player interacting with them (redstone activated doors are unaffected).
Doors placed above gold blocks auto-close in 30 ticks (~1.5 seconds):
Doors placed above iron blocks auto-close in 60 ticks (~3 seconds):
If the block underneath the door is neither an iron nor a gold block they will not auto-close.
Installed on client works on single-player worlds, if installed on server nothing needs to be installed on clients.
