About this Mod

PathFinder API is a dedicated command parsing API for Minecraft mods. It does not provide the suggestion UI itself; that is included in the Ultimate Backport Mod.

  • Normal command suggestions do not require your mod to include the API.
  • Dynamic suggestions require the API to be integrated into your mod.

This mod is needed by Ultimate Backport Mod and other mods depending on the API.

How it works:

  1. Command data can be generated easily at pathfinder.julianweinelt.de.
  2. Upload the generated JSON file on the website.
  3. Others can now easily download it in-game.
  4. PathFinder API handles parsing and prepares the commands for use in the game or UI.

Key Features:

  • Lightweight parsing of commands, arguments, types, and custom suggestion lists.
  • Works seamlessly with Ultimate Backport Mod for dynamic in-game suggestions.
  • JSON-based workflow makes integration simple – no coding required for normal suggestions.
  • Fully modder-friendly, easy to extend or integrate with your own tools.

Frequently Asked Questions

PathFinder API server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.12.2). You can switch loaders with one click in the panel.

Is PathFinder API compatible with forge?

PathFinder API officially supports forge for Minecraft 1.12.2. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with PathFinder API – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if PathFinder API consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
