About this Mod

InputEngine

A seamless cross-platform bridge capturing custom keystrokes from the Minecraft client to the server!

📖 Overview

InputEngine is a powerful utility mod/plugin designed to capture custom keystrokes from the Minecraft client and transmit them instantly to the server. It allows server-side plugins to react seamlessly to custom client-side keybinds (e.g., Skill 1, Dodge, Open Custom Menu).

This project acts as a two-part bridge: a Client Mod (Fabric/NeoForge) and a Server Plugin (Spigot/Paper).

✨ Features

  • 🎮 Client-Side Keybinding: Registers custom keybinds on the client. Fully supports both Fabric and NeoForge.
  • Network Bridge: Sends efficient, lightweight payloads to the server whenever a bound key is pressed or released.
  • 🌍 Vanilla Server Compatible: The networking channel is optional on the client. You can safely keep the mod installed while joining vanilla servers without being disconnected!
  • 🛠️ Server-Side API: Exposes a custom Spigot Event (PlayerKeyPressEvent) for developers so your server-side plugins can easily listen and react to player inputs.

📥 Installation

InputEngine requires both a server-side plugin and a client-side mod to function correctly.

For Players (Client)

  1. Download the correct version for your mod loader (Fabric or NeoForge).
  2. Place the downloaded .jar file into your Minecraft client's mods/ folder.
  3. Fabric Users: Ensure you have the Fabric API installed.

For Server Owners (Plugin)

  1. Download the Spigot release file.
  2. Place it in your Spigot/Paper server's plugins/ folder.
  3. Restart your server.

💻 For Developers (API Usage)

If you are developing a Bukkit/Spigot plugin and want to react to a player's key press, you can easily use the API!

Listen to the PlayerKeyPressEvent:

import dev.darkblade.mod.input_engine.server.api.PlayerKeyPressEvent;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;

public class MyPluginListener implements Listener {

    @EventHandler
    public void onPlayerKeyPress(PlayerKeyPressEvent event) {
        if (event.isPressed()) {
            event.getPlayer().sendMessage("You pressed: " + event.getAction().name());
        } else {
            event.getPlayer().sendMessage("You released: " + event.getAction().name());
        }
    }
}

Frequently Asked Questions

InputEngine server crashes on startup – what to do?

Most common cause: wrong fabric 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 (1.21.11). You can switch loaders with one click in the panel.

InputEngine officially supports fabric, neoforge, paper, purpur, spigot for Minecraft 1.21.11, 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with InputEngine – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if InputEngine consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
