Combat+ Core

by Provismet

Combat+ Core is a Fabric and Quilt library that the other mods in the Combat+ series build on, providing shared melee weapon and dual weapon code.

FabricQuiltClient and serverMIT LicenseOpen source1.20 – 1.21.11

What it does

The library defines a melee weapon base class. A melee weapon must implement a damage value, and it receives callbacks for charged attacks, critical attacks and kills, so weapon mods can react to those moments without writing that logic themselves. Its dual weapon base extends the melee weapon, so an item can be used in either hand and can support enchantments that act on the offhand, with a method for offhand damage.

Enchantments added by Combat+ mods can be set as incompatible with other enchantments that share a tag group. The example given is a weapon utility enchantment that conflicts with other enchantments in the combat-plus:weapon utility tag. The library requires Fabric API and runs on client and server, so the server and every player need it. Files are published for Fabric and Quilt, with the latest build, 4.0.1+1.21.11, targeting 1.21.11 and dated 2025-12-23.

Key features

  1. Melee weapon base class

    Weapon items extend a shared base that requires a damage value and exposes charged, critical and kill callbacks.

  2. Dual weapon support

    Items built on the dual weapon base can be wielded in either hand and carry an offhand damage method.

  3. Offhand enchantments

    The base supports enchantments that take effect when a weapon is held in the offhand.

  4. Enchantment incompatibility tags

    Combat+ enchantments can be marked incompatible with others in the same tag group, such as the weapon utility tag.

Use cases

Building a melee weapon mod

Developers subclass the melee weapon base to get damage, attack callbacks and kill handling for a new sword or axe.

Adding dual wield items

A mod with two-handed or paired weapons can build on the dual weapon base instead of writing its own offhand logic.

Who it’s for: Mod developers building weapons or enchantments for the Combat+ series, and players who want those mods to work together without conflicting enchantments.
