Description

📖 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)

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

For Server Owners (Plugin)

Download the Spigot release file.
Place it in your Spigot/Paper server's plugins/ folder.
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()); } } }
