A mod that lets players toggle PvP individually, while offering some neat extra features that I reckon you may find useful. I am also aware that quite a few mods do something similar, but I felt like I could make something beyond a simple toggle.

• PvP preferences: Players choose whether to disable or enable PvP for themselves
• Colored name tags: Uses vanilla's teams to show off players' PvP states
• Combat flagging: While flagged, toggling is disabled, and disconnecting for any reason while it's active will result in being immediately killed
• Global PvP: Force PvP on or off for all players server-wide; this takes priority over everything else
• Pet protect: Protect all tamed mobs from players whose PvP is off (the pet owner’s PvP state is not factored in)
• Forced PvP in other dimensions: You can force PvP in specific dimensions
• LuckPerms support: Allows you to customize accessibility to things
• Configurability: Some stuff can be configured; for info on what is configurable, go down to the configuration section

This mod ignores the pvp setting in server.properties. Stick to the newest versions of the mod, as older versions may have bugs or lack features as my work is not perfect. Make sure to read the dependencies section as well.

• Fabric API
• LuckPerms (Optional if you don't care about customizing permissions).

There's also the pvptoggle.op.exempt permission node that marks you as immune against penalties such as being flagged, being put on cooldown, etc.

Once again, as was said in the dependencies section, you can completely ignore permission nodes if you do not care for customizing them via another mod like LuckPerms. All nodes labeled as "player" are available to everyone by default, while ones labeled as "op" are available to anyone with an operator permission level of 2 or higher.

Configuration file path: config/pvptoggle/pvp-toggle.json (Generated on launch).

{
  // WARNING: DO NOT COPY THIS EXAMPLE JSON

  // Cooldown for toggling
  "toggle_cooldown": 120.0,

  // How long one is flagged for after engaging in combat
  "combat_flag_duration": 60.0,

  // Default PvP preference for new players
  "default_pvp_preference": true,

  // Console feedback
  "broadcast_to_other_ops": false,

  // These should be self-explanatory
  "punish_combat_log": true,
  "protect_tameables": true,
  "force_pvp_in_other_dimensions": false,
  "team_colors": true,
  "prevent_item_pickup_when_pvp_off": false,
  "forced_pvp_in_other_dimensions": {
    "minecraft:overworld": false,
    "minecraft:the_nether": false,
    "minecraft:the_end": false
  },

  /* For example, putting "tpa" in the list of commands to blacklist will blacklist any command with the word "tpa" in it. 
  You are also able to blacklist specific commands such as "tpaaccept" without outright blacklisting every related command */
  "blacklisted_commands_when_flagged": [
    "tpa",
    "home"
  ]
}

Every setting is a boolean value (true/false) besides toggle_cooldown and combat_flag_duration, which are floats that start from 0.0 to a maximum of 9999.0 seconds.

Edit the values and restart the server or use /pvp reload to apply said changes. Delete the JSON file if it ever becomes malformed to let it regenerate.

Thank you for downloading. I would really appreciate it if you could report any potential issues you encounter in the comments section of the mod page, as I currently have no other way to receive feedback. You can also support me by sharing the mod around, as it really motivates me to work on it when there are people benefiting from its usage, no matter how small.
