No Feather Attack

[aka Feather Attack Cancel]

Feather hit is not an attack — a small Paper plugin that turns feather hits into knockback-only interactions. It cancels damage (so villagers don’t get angry and no damage side-effects fire) while still applying a light custom knockback.

Features

• Knockback-only feather hits: cancels the damage event and applies custom push.
• Per-player toggle via command /featherhit.
• Auto-enable on player join (and on plugin reload for already-online players).
• Client language message support: en_us, de_de, fr_fr, es_es, hu_hu.
• Builds for multiple MC versions via Maven profiles (1.21.7 and 1.21.8).

Requirements

• Java 21 (Paper 1.21+ requires Java 21).
• PaperMC server 1.21.7 or 1.21.8 (matching the built JAR).

Installation

1. Download/build the JAR for your server version (see Build section).
2. Place the JAR into your server’s plugins/ folder.
3. Start the server. The plugin will create:
   • plugins/NoFeatherAttack/config.yml
   • plugins/NoFeatherAttack/lang/*.yml

Commands

• /featherhit — Toggle feather knockback-only mode for yourself.

Permissions: none (by default all players can use the command).

Configuration

File: plugins/NoFeatherAttack/config.yml (use spaces only, no TABs)

Keys

• trigger-item: Uppercase Bukkit material name for the item that triggers the knockback-only hit. Default: FEATHER

• knockback:

  • min-charge: Number (0.0–1.0). Minimum attack cooldown required to apply knockback. 1.0 = fully charged. Default: 0.9
  • horizontal: Number. Base horizontal strength of the knockback vector. Default: 0.6
  • min-upward: Number. Ensures at least this upward (Y) component so hits don’t push targets downward. Default: 0.35
  • scale-by-charge: Boolean. If true, scales horizontal strength by the current attack charge (prevents weak spam from being as strong as full hits). Default: false
  • clamp-velocity: Boolean. If true, clamps the target’s final velocity magnitude to avoid “stacking” launches. Default: true
  • max-velocity: Number. Maximum final velocity magnitude when clamping is enabled. Default: 1.2

• behavior:

  • auto-enable-on-enable: Boolean. When the plugin enables (e.g., server start/reload), automatically enables the feature for players already online. Default: true
  • auto-enable-on-join: Boolean. Automatically enables the feature for players when they join. Default: true

Applying changes

• There is no reload subcommand; /featherhit only toggles the feature for the executing player.
• To apply config changes, restart the server (or stop/start).

Language files

• Path: plugins/NoFeatherAttack/lang/
• Fallback order: exact client tag (e.g., de-de.yml) → underscore form (e.g., de_de.yml) → en_us.yml.
• Color codes: use & (e.g., &6, &a).

Examples

# Softer knockback that scales with charge
trigger-item: FEATHER
knockback:
  min-charge: 0.9
  horizontal: 0.45
  min-upward: 0.30
  scale-by-charge: true
  clamp-velocity: true
  max-velocity: 1.0
behavior:
  auto-enable-on-enable: true
  auto-enable-on-join: true

Notes on Namespaced Command Suggestions

If tab-complete shows a namespaced command like /nofeatherattack:featherhit, this comes from the plugin name namespace. On Paper, you can hide namespaced suggestions by setting send-namespaced=false in paper-global.yml (or relevant Paper config for your version).
