Simple Combat Calculator
Simple Combat Calculator replaces the usual flat weapon damage with a calculation that adds positional, durability and environmental modifiers to every hit.
What it does
Each attack passes through a damage calculation built from several factors: the attacker's weapon position, whether the strike comes from the front or from behind, the condition of the weapon, and environmental modifiers. Critical hits and backstab attacks add their own bonuses on top of the base value, and an elemental damage system is included. Status effects are integrated with the calculation, so effects on either combatant can change the final result.
The mod runs on the client and the server, so both sides need it for the calculation to match. Fabric API is required, and files are published for Fabric, Forge and Quilt for Minecraft 1.20.1. The code is released under the GNU General Public License v3.0 only and is open source, with the source code available for inspection.
Key features
Positional combat
Weapon position and the direction of an attack change the damage, with frontal attacks taking a 5 percent penalty.
Backstab bonus
Attacks from behind receive a 25 percent damage bonus, rewarding players who flank an opponent.
Weapon condition
Damage scales with durability: peak condition adds 15 percent, while critical condition at 0 percent takes a 30 percent penalty.
Critical hits and elements
Critical hits add a 35 percent damage bonus, and an elemental damage system adds another damage type to attacks.
Environmental modifiers
Surroundings and status effects feed into the calculation, so combat outcomes depend on more than the weapon alone.

How it compares
Better Combat Reach Fix is a Forge mod for 1.20.1 that is client and server and is not open source, so it does not alter damage the way this calculation does. QoLculator is a Forge mod for 1.20.1 that runs client-side only and is also not open source. Minecalc is open source under the MIT License, but it is client-side only and covers 1.18.2 – 1.20, so it does not match this mod's Fabric, Forge and Quilt builds for 1.20.1.
