Development Plugin

A powerful, all-in-one utility plugin for Paper/Spigot 1.21.1+ servers. This plugin allows server owners to create custom GUIs, dynamic commands, interactive items with map art, holograms, and boss bars—all without touching a single line of code or restarting the server.

• Visual Editor: /develop gui interface <name>
  • Left Click (with item): Set an item in a slot.
  • Shift + Left Click: Set/Update an item and prompt for a chat command.
  • Right Click: Remove a button from a slot.
• Create a GUI: /develop gui create <name>
• Set a Button (Command): Hold an item and run /develop gui setbutton <name> <slot> <command>
• View a GUI: /develop gui view <name>

2. Dynamic Commands

Create your own server commands on the fly.

• Create Command: /develop cmd <name> <execution_command> <level>
  • Levels: 4 for OP only, 1 for all players.
  • Placeholders: Use {player} for the runner's name, or {0}, {1} for arguments.

3. Custom Items & Map Art (Work in Progress)

Craft unique items with custom NBT data or render images onto Minecraft maps.

• Give Item: /develop item <material> <name> <lore> <nbt_key:val> [image.png]
  • Lore: Use | for line breaks.
  • Map Art: Drop a .png into /plugins/Development/images/ and specify the filename as the last argument to render it onto a map!
  • Example: /develop item DIAMOND_SWORD "&bExcalibur" "&7A legendary sword|&ePower: 9000" "custom:sword"
