Olden Guns

Olden Guns brings black powder guns into the game through four flintlock weapons. The author forked ewewukek's musket mod, credits that base code, and kept parts of its older assets. Each weapon has a cooldown after it is equipped, which stops hotbar switching from being used for rapid fire, and reload duration can be configured so the reload sounds scale with it.

The rifle is similar to the musket but has a rifled barrel, which gives it much greater accuracy and lets it hit targets at longer distances, at the cost of a slower reload and a more expensive crafting recipe. At close range, the blunderbuss fires a spread of small projectiles in one shot, which makes it a primitive shotgun with heavy damage. Weapons at zero durability receive a debuff, which encourages players to keep them maintained.

The server and every player need the mod installed. It is published for Fabric only, for three game versions: 1.18.2, 1.20.1 and 1.20.4. The author recommends pairing it with the Invulnerability Tick mod, which the author says helps the guns reach their full potential on hardware with poor performance. The source code is public and the code is released under the MIT License, so the mod is open source.
