Rocket Crafting Server

Nikola Lukic 16 March, 2022 | 5 min read

Rocket Crafting Servers for Rocket Craft (ue4 project) clients.

General status : underconstruct

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. Run rocketcraftingserver in local (dev):

This project can start without rocket-craft projects. If you wanna use your own client app you can use it with rocket-crafting-server (REST)used only httpRequest.

Run Admin panel

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 password public database password

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 DBNAMEROCKET_ID db.author.insert({"name":"Nikola Lukic 2021"}) Format:

firewall-cmd –zone=public –permanent –add-port PORT/tcp Examples for cent os 8 in case of signaling server useage:

sudo firewall-cmd –permanent –add-port=5349/tcp sudo firewall-cmd –permanent –add-port=5349/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 At the end it looks like:

mongo –host IP-OR-HOST –port SECRETPORTCUSTOM -u "userAdmin" –authenticationDatabase "admin" -p Manual operate with database:

show dbs use 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.

Signaling Server host [optimal] 80 - for all HTTP requests coming from clients. To change this value, set the –httpPort parameter for the Signaling Server.

443 - for all HTTPS requests coming from clients, when the Signaling Server is running in HTTPS mode. To change this value, set the –httpsPort parameter for the Signaling Server.

8888 - for all incoming connection requests from the Unreal Engine application. To change this value, set both the –streamerPort parameter for the Signaling Server and the -PixelStreamingPort parameter for the UE4 application.

Matchmaker Server host [optimal] 90 - for all HTTP requests coming from clients. To change this value, use the –httpPort parameter for the Matchmaker Server.

9999 - for all messages sent by the Signaling Server. To change this value, set both the –matchmakerPort parameter for the Matchmaker Server and the –matchmakerPort parameter for the Signaling Server.

Multiplayer proxy servers for support [optimal] From ue4 engine recommended files

Turn server come from webRTC excellent feature for next update. Be sure:

npm install -g npm 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)); For private job i also run KureOrange at: https://kure.maximumroulette.com/
