ChangeSkin

Description

This plugin allows your players to change their skins with a simple command. You can choose every skin another Minecraft user currently has. It is also possible to set a custom standard skin. If you want to, this plugin can set this standard skin for all players who still have the default Steve or Alex skin.

Security

Software security is important. In order to inform people quickly and get patches deployed promptly, this projects discloses issues transparently and detailed.

Issue Severity Affected Patched Impact
#205 Moderate Bungee Module after 92ed029 - (2.3.2+) ba1957a DOS (Denial-of-Service) Modified Minecraft clients could send malicious plugin messages (internal not chat). This causes an exception. Exceptions are CPU intensive if they are spammed a lot!

If you have any questions, please open a new issue or send a private message on Spigot. Later should be also used for reporting in order to work on fix before publicly disclosing it.

Features

  • Skins for offline mode servers
  • Upload custom skins (using the /skinupload command)
  • BungeeCord and Sponge support
  • SQL Storage
  • Change your skin - Every skin which has ever uploaded to Mojang is allowed
  • Lightweight
  • Easy to use
  • Implemented cache to benefit performance
  • Nearly no mojang rate limits due to caching

Commands

/setskin <uuid> [keep] - Sets your skin to be the same as the player with the selected uuid.
/setskin <username> [keep] - Sets the skin equal to the owner of that Mojang account with the given username.
/setskin reset - Resets the skin of the invoker to his one.
/setskin <onlinePlayer> <newSkinUUID|newSkinPlayerName> [keep]
/skinupdate [onlinePlayer] - Invalidates the database entry and fetches the fresh skin from the Mojang servers.
/skinupload <url> - Upload a skin to a mojang account
/skin-select <name> - Choose a skin from the database which has a specified name
/skinskull - Changes the skin of a holding skull from the database which has a specified name
/skin-info - Show details about the currently assigned skin like skin url owner name, uuid and more

Keep prevents the skin from auto updating. See the config for more information about auto updating.

/skin, /set-skin, /changeskin can used as an alias for /setskin

Permissions

For Sponge users:

Sponge uses a different permissions model. This means changeskin.command.setskin includes all child permissions.
(Including changeskin.command.setskin.other). To workaround this please use changeskin.command.<command>.base
instead of changeskin.command.<command> to give the permission only to modify their own skin.
**This workaround will be removed in the next major version 4.0. Then the Bukkit and BungeeCord will have the same logic.
  • changeskin.command.skinupdate - Command to refresh a player's own skin
  • changeskin.command.skinupdate.other.uuid - Allows to update the skin of that specific user
  • changeskin.command.skinupdate.other.* - Allowed to update the skins of all players
  • changeskin.command.setskin.* - Includes all the commands below
  • changeskin.command.setskin - Set your own skin
  • changeskin.command.setskin.other - Set the skin of other players
  • changeskin.command.skinselect - Select a skin from the database
  • changeskin.command.skinupload - Upload a skin to one of the configured accounts
  • changeskin.command.skinskull - Use the skull command
  • changeskin.command.skininfo - Use the info command

Whitelist and blacklist permissions

Whitelist

  • changeskin.skin.whitelist.uuid - Allow this specific skin
  • changeskin.skin.whitelist.* - Allows all skins

Blacklist

  • changeskin.skin.whitelist.*
  • -changeskin.skin.whitelist.uuid

=> This means all skins are allowed except the ones with the uuid in the blacklist list

Requirements

  • Java 8+
  • Minecraft server software
    • Spigot 1.8.8+ or any fork of it (ex: Paper)
    • Sponge 7+
    • Latest BungeeCord (Keep in mind that BungeeCord is backwards compatible)

Upload a skin to the database

  3. Type /skin-upload [url] (example: https://i.imgur.com/4lV1m26.png)
  4. Now you see the skin id it's saved as
  5. Type /skin-select 3 or /skin-select skin-3

How to install on BungeeCord

  1. Install the plugin on both BungeeCord and Bukkit server
  2. Activate BungeeCord support in your Spigot configuration (bungeecord: true in spigot.yml)
