AutoCloseDoors

Lightweight Valheim/BepInEx mod that closes opened doors and gates after a configurable delay, but only when no player is near the door. Autoclosing can be disabled inside dungeons/interiors and is disabled there by default.

Behavior

Tracks only doors that are currently open.
Uses a coroutine that sleeps until the next tracked door is due; there is no per-frame Update/tick patch.
Checks all players with Valheim's own Player.IsPlayerInRange.
Closes by setting the door ZDO state to 0, so an already closed door is never toggled open by accident.
Detects nearby linked/double doors on demand, only while processing an opened door.
Skips dungeons/interiors by default, with a config toggle to enable them.

Config

Generated by BepInEx at:

BepInEx/config/obelisk.valheim.autoclosedoors.cfg

Options:

Enabled: enable/disable the mod.
Enable in dungeons: enable/disable automatic closing inside dungeons/interiors. Disabled by default.
Player radius: radius around each door leaf that keeps it open.
Close delay seconds: delay before closing, clamped by config range from 2 to 10.

Multiplayer

The mod uses Valheim networked door state (ZDO) and door ownership, so the close is replicated through the normal multiplayer state sync. Install it on the server and clients in a modded multiplayer setup for consistent behavior.
