Door Knocker (Forge)
With Door Knocker installed, a player holding a key can knock on a door or trapdoor from the outside to make it open, and a short cooldown keeps the knocking from being spammed.
What it does
Door Knocker gives players a way to knock on doors and trapdoors. The action is meant to add immersion to roleplay and to play with friends, and the author describes it as a simple addition. The project is a Forge build of a knocking mod that originally ran on another loader, so its behavior follows that original design.
Players knock by holding a button that the mod binds, and the knock is limited by a cooldown so it cannot be repeated quickly. The author notes that a knock may only trigger while the button stays held down for a set period, and that the cooldown logic was adjusted to fix a problem with event handling. Breaking a door also ends the knock action, so a broken door cannot be knocked on again.
Installation covers the server and each player's game. Files exist for Forge across nine release versions 1.16 – 1.20.1, including 1.16.5, 1.19.2 and 1.19.4, with 1.3.0 for 1.20.1 as the latest file. Snapshot builds are published, and the code is released under the MIT License, so the project is open source. Public source code and an issue tracker are linked from the project page.
Key features
Knocking on doors
Players can knock on a door from either side with a bound button to make a knock sound and trigger the door.
Knocking on trapdoors
Trapdoors respond to the same knock, so the action works on both door types.
Knock cooldown
A cooldown limits how often a knock can happen, which prevents players from spamming the action.
Roleplay immersion
The knock adds a small interaction that suits roleplay servers and play with friends.

How it compares
Knock On Wood is the other mod on this list that adds knocking, and it is open source under the MIT License with Fabric and Forge files for 1.20.1, so it supports Fabric where Door Knocker does not. Shroomscape is a Forge and NeoForge mod that covers 1.16.5 – 1.21.4 and is not open source, so it fits players who need a wider version range but does not add a knock action. Floating Trapdoors is client-side only under All rights reserved, and Squid Doors is a client and server mod for Forge 1.20.1 under All rights reserved, so neither matches the server-and-client setup of Door Knocker.
