Rocket Crafting Servers

for Rocket Craft (ue4 project) clients.

General status : ROCK 2024

Project original name : Rocket Crafting Servers to avoid misunderstandings with other randomly similar server names. Rocket is an alias for Unreal engine.

=> Migrate to ue4 builded from source. => Only active for now is 4.24.3 , i will wait until finish Barbarian Road Mashines basic demo with one game play map.

Get server account part:

https://github.com/RocketCraftingServer/rocket-craft-server

Basic account session staff based on node.js and MongoDB. Integration done:

• Node.js http1.1/http2 server
• Basic session account support (mongoDB)
• Vue-Typescript administrator panel project
• Test clients (rocket-craft repo)
• Rocket-craft client (4.22) exchange IP for opened dedicated users server run.
• Basic implementation for client library safir or any vanilljs.

Run rocketcraftingserver in local (dev):

Run Admin panel

In term of storage/ [public access for external clients], rocketcraftingserver depens on admin-panel! Also npm run serve will not delete storage/ folder but npm run build will do.

Do not use git or npm commands on your public server. Better way is to build on local and then simple upload project. Do not use any dev tools on public server it is my personal advice.

From ue4 client

- First case is `Barbarian Road mashines` race game.

Project structure

• First char in name I (for example IApp.ts) represent current interface used for generating API documentation.
• Dont upload this project in www, htdocs, public folder on you public domain mashine. Like any node.js app.
• Folder admin-panel is somekind of sandbox. Dont import any file from root like congif.js. Even admin access it is still posible for public access.
• Top secret list:
  • system email mailtrap api
  • public database password

Status/info:

• Admin Panel (Vue-ClassComponent-Typescript)
• Debugging proccess for server part with Visual-Code. (Launch.json tested on windows)create folder.vscodein root of workspace and copylaunch.json`. Please use debugger and learn and feel node iterrator flow.
• Admin ban user [NEXT]
• Active servers list [DONE]
• Admin only - delete profile [done]

Production

Public RocketCraftingServer API: Prefix: rocket

• http://maximumroulette.com/

Admin panel:

• http://maximumroulette.com/admin

Note:

• Make shiled from Hacker attacks. Recommended is to run mongo without remote access! Make strong database password Use permission by definited host be mac-address or ip...

  All this prevent job is minimum action to make your server application stay a live.

  About .permission there is no setup this arg from code. Use MongoDB console or GUI Mongo DB Compass. This is all free. Just replace value basic with admin.

Basic data:

• Dedicated Server CentOS 8.3
• Build shipping version at the end.

Security:

• Use non standard port it si small but good secury feature.
• If you have mongo on same mashine use bind localhost not domain name.

It is easy to use distribution platform with more servers host mashines.

  mongo --host IP-ADDRESS-OF-MONGODB-SERVER --port PORT_NUMBER

Be aware of NAT and need to have opened port if you have firewall active on your server.

• CentOS 8.3

 use DB_NAME_ROCKET_ID
 db.author.insert({"name":"Nikola Lukic 2021"})

Format:

firewall-cmd --zone=public --permanent --add-port PORT/tcp

Examples for centos in case of signaling server and UE4 server useage:

sudo firewall-cmd --permanent --add-port=999/tcp
sudo firewall-cmd --permanent --add-port=999/udp
sudo firewall-cmd --permanent --add-port=63000-64535/udp

firewall-cmd --zone=public --permanent --add-port 85/tcp
firewall-cmd --zone=public --permanent --add-port 8888/udp
sudo firewall-cmd --reload

Server flow

For production or stage server dev use secured arg and also you need to have ssl private key and .crt file. Run:

  npm run app

Localhost MongoDB setup:

• run mongodb service on your computer

Then attach it:

  mongod --dbpath data --bind_ip <DOMAIN>

At the end it looks like:

mongo --host IP-OR-HOST --port SECRET_PORT_CUSTOM -u "userAdmin" --authenticationDatabase "admin" -p

Manual operate with database:

show dbs
use <database_name>

db.users.update({},{$set : {"role":"user"}},{upsert:false, multi:true})

Deep look at package.json in root dir:

  "scripts": {
    "app": "node server maximumroulette.com secured",
    "sameDomain": "node server IP_ADDESS secured"

Ue4 Clients -> Must be game engine builded from source. Generate visual studio source files. Build on right click -> first ue4 instance than build game instance. Use Development or Shipping - Editor If you wanna dedicated server build Development-Server or Shipping-Server build configuration in visual studio. For package run also game engine from source and simple package selected platform. For all platforms

4.24.3 Main reason is devices with opengles < 3.0 support plus Linux supported websocket experimental net driver [also dedicated server works fine].

This is Tradicional way. On finish whole this staff i will add future modern way brach ( 4.26 > ) with last ue4 upgrade.

GamePlay Servers NEW FEATURE [wip]

Best solution for one direction communication. First example comes for roulette server logic.

Server part:

/**
 * @description
 * GamePlay Servers part
 * Based on `Server Events` tech.
 */
if (config.gameServers.matrixRoulette.active == true) {
  // let clients = [];
  let facts = [];
  const matrixRouletteCore = require("./game-servers/matrix-roulette/roulette-server.js");
  matrixRouletteCore.clients = [];
  matrixRouletteCore.init();

  hostingHTTP.get("/matrix-roulette-status", (request, response) =>
    response.json({clients: matrixRouletteCore.clients.length})
  );

  function eventsHandler(request, response, next) {
    const headers = {
      "Content-Type": "text/event-stream",
      Connection: "keep-alive",
      "Cache-Control": "no-cache",
    };
    response.writeHead(200, headers);
    const data = `data: ${JSON.stringify(facts)}\n\n`;
    response.write(data);
    const clientId = Date.now();
    const newClient = {id: clientId, response};
    matrixRouletteCore.clients.push(newClient);
    request.on("close", () => {
      console.log(`${clientId} Connection closed`);
      matrixRouletteCore.clients = matrixRouletteCore.clients.filter(
        client => client.id !== clientId
      );
    });
  }

  hostingHTTP.get("/matrix-roulette", eventsHandler);

  // |In case of adding new Event from client by the POST call.
  // No need for roulette logic.
  // async function addFact(request, respsonse, next) {
  // 	const newFact = request.body;
  // 	facts.push(newFact);
  // 	respsonse.json(newFact)
  // 	return sendEventsToAll(newFact);
  // }
  // Update from clients
  // hostingHTTP.post('/fact', addFact);
}

On client: From matrix-engine-starter project MAtrixRoulette:

console.log("ServerEvent[maximumroulette.com/matrix-roulette]");
const events = new EventSource("https://maximumroulette.com/matrix-roulette");
events.onmessage = event => {
  const parsedData = JSON.parse(event.data);
  if (typeof parsedData.matrixRoulette === "undefined") {
    return;
  }
  console.log(
    "[serverEvent:matrix-roulette]",
    parsedData.matrixRoulette.status
  );
  if (parsedData.matrixRoulette.status == "MEDITATE") {
    //
    this.status.game = "MEDITATE";
    dispatchEvent(
      new CustomEvent("MEDITATE_SERVER", {
        detail: parsedData.matrixRoulette.counter,
      })
    );
  } else if (parsedData.matrixRoulette.status == "RESULT") {
    //
    this.status.game = "RESULT";
    console.log(
      "[serverEvent:matrix-roulette[win number]]",
      parsedData.matrixRoulette.winNumber
    );
  } else {
    alert();
  }
};
events.onerror = event => {
  console.log("ServerEvent Error:", event);
};

Geolocation ip support [optimal] WIP

Test -> https://radar.cloudflare.com/ip/87.116.141.57 https://ipinfo.io/account/home?service=google&loginState=create

Test from browser console

Read more at routes.md

From http://maximumroulette.com/ or from your own server.

• Login:

fetch("/rocket/login/", {
  method: "POST",
  headers: {
    Accept: "application/json",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    emailField: "zlatnaspirala@gmail.com",
    passwordField: "123123123",
  }),
})
  .then(response => response.json())
  .then(data => console.log(data));
