- use every node.js feature!
- using async/await
- accessing entire paper api
- accessing custom classeses
- accessing custom classes from other jars
- getting raw values from java objects
- getting java object references (look to example code)
- registering commands
- registering events
- cancelling events
- unrefing objects from memory
- and more!
todo
- [ ] full typescript support for java objects
how to use
- add the latest nodeinpaper-client plugin to your paper server
- add nodeinpaper-server to your node.js project
- enjoy! (look to example code)
example api
example code is below.
import { createNIPServer } from "nodeinpaper-server";
const nip = createNIPServer({
port: 6798,
host: "0.0.0.0",
});
nip.register(async ({ api: { $plugin, $class, $classFromPath }, onDisconnect, registerCommand, registerEvent }) => {
console.log("Registered!");
let interval = setInterval(async () => {
const [onlinePlayers] = await $plugin.getServer().getOnlinePlayers().$get();
onlinePlayers.forEach(async (player: any) => {
const [res] = await player.$get(
{
uuid: (p: any) => p.getUniqueId().toString(),
x: (p: any) => p.getLocation().getX(),
y: (p: any) => p.getLocation().getY(),
z: (p: any) => p.getLocation().getZ(),
}
);
player.sendActionBar(`X: ${res.x.toFixed(2)} Y: ${res.y.toFixed(2)} Z: ${res.z.toFixed(2)}`).$run();
});
}, 100);
registerCommand({
name: "nodejs-test",
async onExecute(sender, label, ...args) {
const [playerName] = await sender.getName().$get();
console.log("Command executed!");
await sender.sendPlainMessage(`Hello from node.js! Your name: ${playerName}`).$run();
sender.$unRef(); // don't forget to unref the sender from memory
}
})
registerEvent({
name: "org.bukkit.event.player.PlayerToggleSneakEvent",
async onExecute(event) {
const [player] = await event.getPlayer().$get();
const [isSneaking] = await event.isSneaking().$get();
console.log(`Player ${await player.getName().$get()} is sneaking: ${isSneaking}`);
await player.sendPlainMessage(`Sneaking: ${isSneaking}`).$run();
event.$unRef(); // don't forget to unref the event from memory
}
})
registerEvent({
name: "org.bukkit.event.player.PlayerChatEvent",
cancelConditions: {
and: [
{
a: {
base: "Context",
path: (c) => c.getMessage()
},
b: "cancel me",
op: "=="
}
]
},
async onExecute(event) {
const [message] = await event.getMessage().$get();
const [isCancelled] = await event.isCancelled().$get();
console.log(`chat is cancelled: ${isCancelled}`);
console.log(`Message: ${message}`);
$plugin.getServer().broadcastMessage(`[Chat] ${message}`).$run();
event.$unRef(); // don't forget to unref the event from memory
}
})
onDisconnect(() => {
clearInterval(interval);
});
});
nip.init();
alternative executors
.$run()
: runs the method on server asynchronously and returns a promise without any value.$get()
: runs the method on server asynchronously and returns a promise with the value.$runSync()
: runs the method on server synchronously and returns a promise without any value.$getSync()
: runs the method on server synchronously and returns a promise with the value.$exec()
: look into source code.$execSync()
: look into source code.$unRef()
: unrefs the object from memory (from java side)
