GPS Plugin
A Bukkit/Spigot Minecraft plugin that allows players to create a GPS compass to navigate to specific coordinates. Players can reroute the compass a limited number of times before it breaks.

Features

• Players can set a GPS compass pointing to specified coordinates using /gps <x> <z>.
• The compass can be rerouted up to a configurable number of times using /reroute <x> <z>.
• The number of reroutes left is displayed in the item lore.
• The compass breaks after reaching the reroute limit, playing an item break sound.
• Requires players to have gps.use permission to use the commands.
• The maximum reroutes allowed is configurable in config.yml.

Commands

Command Description Permission
/gps <x> <z> Creates a GPS compass pointing to the given coordinates. Requires 10 compasses. gps.use
/reroute <x> <z> Updates the compass to a new location (limited reroutes). gps.use
Permissions

Permission Description Default
gps.use Allows use of /gps and /reroute commands. true
Configuration (config.yml)
You can configure the maximum number of reroutes before the compass breaks.

max-reroutes: 3

(Default: 3 reroutes before breaking)

How It Works

1. A player runs /gps <x> <z> while holding at least 10 compasses.
2. The command consumes 10 compasses and gives them a special GPS compass.
3. The GPS compass points to the entered coordinates.
4. The player can use /reroute <x> <z> to change the destination (up to the max reroutes set in config.yml).
5. Once the reroutes are exhausted, the compass disappears, playing an item break sound.

Installation

1. Download the plugin JAR and place it in your plugins folder.
2. Restart your server to generate the config file.
3. Edit config.yml in the plugin folder if needed.
4. Reload the server to apply changes.

Planned Features

• Support for multiple worlds.
• More customization options.
• Economy integration for rerouting.
