Both Hands Combat

NeoForge 26.1.2 port of OffHandCombat.

This mod allows players to use an attackable weapon in the offhand and perform independent off-hand attacks, including dual crossbows.

Features

• Use an attackable weapon in the offhand and right-click an entity to perform an independent off-hand attack.
• Keep separate main-hand and off-hand attack cooldowns, including a dedicated off-hand attack indicator.
• Render the off-hand cooldown indicator above the hotbar or crosshair, following Minecraft's attack-indicator setting.
• Support dual crossbows: load the main-hand and off-hand crossbows in sequence, then fire them in sequence.
• Validate off-hand attacks on the server, including target range, line of sight, held item, and cooldown state.
• Preserve vanilla behavior for entities and items excluded through the compatibility tags.

Configuration

Configure the mod through the in-game configuration screen supplied by Jupiter:

• enabled: enables off-hand combat.
• requireLineOfSight: blocks attacks through walls.
• attackTimeoutAfterSwing: main-hand cooldown fraction retained after an off-hand hit.

Compatibility exclusions are controlled with data-pack tags:

• both_hands_combat:disabled_entities (data/<namespace>/tags/entity_type/disabled_entities.json) disables off-hand attacks against the listed entity types and keeps vanilla interaction behavior.
• both_hands_combat:disabled_items (data/<namespace>/tags/item/disabled_items.json) disables off-hand combat for the listed items and keeps their vanilla use behavior.

For example, a data pack can disable off-hand combat for a specific entity type:

{
  "replace": false,
  "values": [
    "minecraft:armor_stand"
  ]
}
