MTR-Dynmap Bridge

MTR-Dynmap Bridge
MTR-Dynmap Bridge is a lightweight bridge between Minecraft Transit Railway (MTR) and Dynmap.

The plugin automatically synchronizes MTR stations and depots with Dynmap and reliably detects the server worlds without hardcoded world names.


Features

• Automatically displays MTR stations and depots on Dynmap
  
  
• Automatically detects worlds and dimensions
  
  
• Supports multiple MTR worlds and dimensions
  
  
• Automatically restores the Y coordinate when determining the surface location
  
  
• Station icon: pin
  
  
• Depot icon: building
  
  
• First synchronization occurs 5 seconds after server startup
  
  
• Further synchronization runs every 60 minutes
  
  
• Automatically removes markers when MTR stations or depots are deleted
  
  
• No server-specific world names are hardcoded in the plugin

Requirements

• Minecraft 1.21 / 1.21.4
  
  
• Youer or another compatible hybrid server that supports NeoForge mods together with the Bukkit, Spigot, and Paper APIs
  
  
• MTR 4.1.0-beta.2
  
  
• Dynmap 3.7-beta8
  
  
• Java 21+

The plugin was tested on Minecraft 1.21.1. / 1.21.4

Hybrid Servers
To synchronize MTR stations and depots, the server must provide access to the MTR mod alongside a Bukkit-compatible API. This can be achieved using a compatible hybrid server such as Youer, which supports NeoForge mods together with the Bukkit, Spigot, and Paper APIs.
The plugin is intended for Minecraft 1.21 and 1.21.4 servers running MTR through Youer or another compatible NeoForge/Bukkit hybrid server.

A standard Bukkit/Paper/Spigot server without the MTR mod may load the plugin, but MTR stations and depots cannot be synchronized without access to the MTR API.

Installation

1. Install MTR and Dynmap on a compatible hybrid server.
   
   
2. Place MTR-Dynmap-Bridge-1.0.0.1.jar into the plugins folder.
   
   
3. Start or restart the server.
   
   
4. The plugin will automatically create its configuration.
   
   
5. MTR stations and depots will appear on Dynmap after synchronization.

No manual configuration is normally required.

Configuration
The plugin automatically creates:

plugins/MTR-Dynmap-Bridge/config.yml

Note: Virus, old, and PartyGames are example world names from the author's server. The plugin automatically detects the worlds available on your server and writes their names to the configuration. No manual changes are normally required.

If multiple possible worlds exist for the same MTR dimension, the mapping can be configured manually in config.yml.

Synchronization
The first synchronization starts approximately 5 seconds after server startup.

After that, MTR synchronization automatically runs every 60 minutes.

Dynmap Markers
The plugin creates an MTR marker set in Dynmap.

• Stations pin icon
• Depots building icon

Markers use the actual Minecraft world coordinates, including a restored Y coordinate when necessary.



Marker Cleanup
MTR markers managed by MTR-Dynmap Bridge are automatically maintained in Dynmap.

If a station or depot is removed from MTR, its corresponding Dynmap marker will be removed during the next synchronization.

Only markers managed by MTR-Dynmap Bridge are affected. Other Dynmap markers are not removed.

What's New in Version 1.0.0.1

• Fixed Dynmap markers remaining after MTR stations or depots were removed
  
  
• Added automatic cleanup of station and depot markers
  
  
• Existing station and depot synchronization remains unchanged
  
  
• Existing icons continue to use the pin and building icons
