Project : Visual ts game engine

Old Version:

• We can fight - 2020
• Out of space - 2021

Current Version Lake of fire 2022

2d canvas game engine based on Matter.js 2D physics engine for the web.

I use my own concept: take lib for the great benefits. It means that i import only staff that i can't make in proper way in proper time, all other coming from head. For example Physics was imported in role of npm package for typescript matter.js/ts variant and i keep dependency healthy. In networking aspect i use full-duplex connection under web-rtc protocol. Pretty nice working combination of physics and realtime-multiplayer connetions. PeerToPeer used for game-play and classic websocket(socketio) for session staff. HTMLRequest used only for loading html parts in run time (on request) because i want clear single page application with all PWA features inside. Also video chat is integrated based on signaling server. You can start recording canvas gameplay with implemented record-canvas.

For npm users

Take a look project examples on: https://github.com/zlatnaspirala/visual-ts-examples

It is nice starter project. Fixed all deps to make npm i visual-ts usable.

API Documentation

Whats good in this project:

• visual-ts correspondent with mongoDB [Its not only for games you have basic session staff you can use it for your standalone application].
• Fast full-duplex connections based on webRTC/socket.io/websocket [node.js]
• Multiplatform/Realtime Multiplayer features.
• Video chat comes with visual-ts [standalone].
• No strange logs - No need for forums just follow stackoverflow.com and wc3.
• Fast console log access, tracking code
• No escape with eval
• Fast rebuild - Build single endpoint, Rebuild all
• Luanch/Attacher debugger options implemented [for visual code]
• Lib is not to much inself closed. Every intervention or used feature is exposed in high level in that way you can make very fast implementation of your own logic what ever will be.
• You are not forced to use typescript you can always downgrade to javascript this comes with typescript inself.
• Example multiplayer

Simple there is nothing between you and making the app.

• Written in typescript current version 4.2.4.
• Package tool used webpack 4.46.0.
• Text editor used and recommended: Last version of Visual Studio Code [1.66.0]. Luanch debugger configuration comes with this project (for server part). Or run server on Javascript Debug Terminal.
• Physics engine based on Matter.js - Matter.ts (npm project).
• Multiplatform video chat (for all browsers) implemented. SocketIO used for session staff. MultiRTC3 alias broadcaster used for video chat also for data transfer.
• Mobile controls / Tested on android Based on touch area bounds LEFT , UP, RIGHT (for platformer based gameplay, for now).

VisualTsGameEngine GUI tool 2d Map Creator made in python:

Much more easyest way to make yor gameplay table sets is creator-2dmap python script. After installation of all needed modules vie pip3 for python3, you need to run:

@Note If you use git clone --recurse-submodules https://github.com/zlatnaspirala/visual-ts-game-engine

Then run creator@dmap with npm run creator

 // Windows 
 python.exe tool.py  
 // Macos - linux  
 python3 ./tool.py

Possible bug on oldies linux os mint. Bug related with tkinter lib.

You need to change self.absolutePacksPath from defaults.py config file. Put example platformer pack folder path: src\examples\platformer\scripts\packs but path must be absolute, my personal path is (For windows users : use double \ for escape ):

This is example for windows users:

E:\\web_server\\xampp\htdocs\\PRIVATE_SERVER\\visual-ts\\project\\visual-ts\\src\\examples\\platformer\\scripts\\packs\\"

 This is separated and added like git submodules.

• This is freeware / opensource . There is no any limitation in this project. You can use video stream as gamePlay objects , multiplayer feature is also free.
• Please don't use fake email address to test public maximumroulette.com platformer example. Project even in dev stage is totally production approach. You can't pass registration with fake email. Just clone , install and run in local (client & server). You need to install and run also MongoDB on your system. Change flag in databased confimed to the true value to skip registration confirmation process.

Client part

To make all dependency works in build proccess we need some plugins.

  npm install

Command (current: single player solution build):

  npm run dev   // or   npm run dev-all

Navigate in browser /build/app.html to see client app in action

New way of building multi entries.

Command is npm run dev-all . This is test for multi instancing webpack capabilities. Webpack in this case use webpack.multicompile.config.js. Thanks for common object definition:

This is best place to manage status of your build action. Just comment or uncomment specific webpack object in this place =>

webpack.multicompile.config.js

module.exports = [ 
 webPackModuleMultiPlayerSolution,
 webPackModuleSingleSimpleSolution,
 webPackModuleMultiChatBasketBall,
 webPackModuleTutorialsDemo1, 
// webPackModuleTutorialsDemo2  DISABLE HERE WHOLE SUB BUILD 
];

Point of Multi entries is to make independent healthy builds end point for our application. Current export's for 3 solutions looks like (runs webpack.multicompile.config.js) :

Command:

  npm run dev-all

-Client part is browser web application. No reloading or redirecting. This is single page application. I use html request only for loading local/staged html (like register, login etc.). Networking is based on webSocket full-duplex communication only. This is good cross for old fasion native programmers not for web server REST oriented skills. No mix in communication usage. You must be conform with classic socket connection methodology and your own idea about connections. webRTC can be used for many proporsion.

Already implemented:

• video chat webRTC (SIP) chat and data communication. based on multiRTC3 for all modern browser's and hybryd implementation (android, ios etc.) (UDP/TCP). Running on socket.
• Bonus connections options - Coordinator another brodcaster. Parallel multiRTC connections. Coordinator is disabled by default but can be used in same way just like broadcaster.
• Simple facebook api script (addson).

-Class 'Connector' (native webSocket) used for user session staff.

• For main account session staff like login, register etc.

Client config

If you want web app without any networking then setup:

appUseNetwork: boolean = false;

You want to use communication for multiplayer but you don't want to use server database account sessions. The setup this on false in main client config class.  appUseAccountsSystem: boolean = false;

• Networking is disabled or enabled depens on current dev status.

Find configuration for client part at ./src/lib/client-config.ts

Please read About Client Configuration

Start dependency system from app.ts

• First game template is Platformer. This is high level programming in this software. Class Platformer run with . Class Starter is base class for my canvas part (matter.js/ts). It is injected to the Platformer to make full operated work.
• gamesList args for ioc constructor is for now just simbolic for now. (WIP)
• In ioc you can make strong class dependency relations. Use it for your own structural changes. If you want to make light version for build than use ioc to remove everything you don't need in build.

ioc.ts files located at: src\controllers. In ioc file i import choosen classes and create instance or bind. Ioc also save (singleton) instance's and we never make same class instance again (this is the role). We just call game.ioc.get.NAME_OF_INSTANCE. Object .get is key access object not array. Best practice is to use only one ioc. In that way you will get clear build without big shared in most time unnecessary data. If you application is big project.Than best way is still use one ioc.ts for per web page. In that way i use refresh or redirect moment to load optimised script bundle for current page.

Main dependency file

• Current version:

/**  * Import global css  */ 
require("./style/animations.css"); 
require("./style/styles.css");  
import AppIcon from "./app-icon"; 
import GamePlay from "./examples/platformer/scripts/game-play";
import Ioc from "./controllers/ioc";
  /**  
    * plarformerGameInfo  
    * This is strong connection.  
    * html-components are on the same level with app.ts 
    * Put any parameters here.  */
const plarformerGameInfo = { 
  name: "Platformer",
  title: "Start Platformer game play", };
const gamesList: any[] = [   plarformerGameInfo, ];
const master = new Ioc(gamesList); 
const appIcon: AppIcon = new AppIcon(master.get.Browser); 
master.singlton(GamePlay, master.get.Starter);
 console.log("Platformer: ", master.get.GamePlay); 
 master.get.GamePlay.attachAppEvents(); 
 /**  
  * Make it global for fast access in console testing. 
  * (window as any).platformer = master.get.GamePlay;  */ 
(window as any).master = master; 
(window as any).platformer = master.get.GamePlay; 

Recording your game

Setup in client-config.ts:

  public recordCanvasOption: any = {   
   injectCanvas: () => document.getElementsByTagName("canvas")[0],  
   frameRequestRate: 30,  
   videoDuration: 20,   
   outputFilename: "record-gameplay.mp4",  
   mineType: "video/mp4",  
   resolutions: '800x600' 
  }

You can use this call:

 platformer.starter.ioc.get.RecordGamePlay.recordCanvas.run();

About runup gameplay

@Note Somethimes i override autoStartGamePlay!

In client-config :

Disabled at the moment for single-player solution. javascript

  private autoStartGamePlay: boolean = false; 

If you setup 'autoStartGamePlay' to false you need to run gamePlay with :

javascript

  master.get.GamePlay.load() 

Note : Only singleton object instance from master start with upcase letters.

Project structure

• build/ is autogenerated. Don't edit or add content in this folder.
• src/ is main client part (Browser web application). Main file : app.ts
• src/libs/ is common and smart pack of classes, interfaces etc. easy access.
• server/ folder is fully indipendent server size. I use one git repo but consider '/server' represent standalone application. There's server package.json independently from client part also config is not the common. I just like it like that.

About Dev Prodc regime

Enum: dev, prod, mongodb.net or mongodb.net-dev

Explanation for: this.serverMode = "mongodb.net-dev"; If you wanna use mongod.net database but you wanna use it from localhost. Multiplayer (with videochat or realtime net) still use https. For single player variant you can use http.

Audios

Audios are not loaded by defoult if you use it in IOC controller. You create audio instance from code. You can mute it all.

Add new sound

• Open webpack and add line: [After this you need to restart webpack.]

new CopyWebpackPlugin([   ...   // Audios   {from: "./src/examples/platformer-single-player/audios/player/dead.mp3", to: "audios/newAudio1.mp3"}   {from: "./src/examples/platformer-single-player/audios/player/dead.mp3", to: "audios/newAudio2.mp3"} ], { debug: 'warn' }) 

• Find nice place for creating instance:

  myInstance.starter.ioc.get.Sound.createAudio("./audios/newAudio1.mp3", "newAudio1");   myInstance.starter.ioc.get.Sound.createAudio("./audios/newAudio2.mp3", "newAudio2");

• Find place where you wanna run play:

root.starter.ioc.get.Sound.playById('jump');

Server part

Installed database : MongoDB server version: 3.5.6

Updated to the last https://tecadmin.net/install-mongodb-on-centos/

-No typescript here, we need keep state clear no. Node.js is best options.For email staff i choose : npm i gmail-send .

-Run services database server (Locally and leave it alive for develop proccess): if you use (running) services mongod no need for this command.

  npm run dataserver

Looks like this :

 mongod --dbpath ./server/database/data

Fix : "failed: address already in use" :

  netstat -ano | findstr :27017    taskkill /PID typeyourPIDhere /F

Cent os:

 mongod  db.changeUserPassword(‘admin’,’<new_password>’)   

• Command for kill all node.js procces for window users :

  taskkill /im node.exe /F

Networking multimedia communication : WebSocketServer running on Node.js

Text-based protocol SIP (Session Initiation Protocol) used for signaling and controlling multimedia sessions.

General networking config:

About generating localhost certs

Read more about cert serverMode dev od prod use https protocol to make full works on both regime (If you using multiplayer example). You need to install cert (mmc.exe) (for User or local Mashine), also in browser:

Note:

• Connector (websocket) no need to be wss. If you wanna use just session communication.

About production running (last version of centos will be nice).

• This is only for localhost test running. On your public server (VPS) you will need to have SSL certification (take a look for free SSL on great https://letsencrypt.org/). Then change in server-config.js parameter serverMode to prod or mongodb.net.
• If you setup with prod it means that you have runned mongodb on public mashine.
• If you setup with mongodb.net it means that you regiter free plan on mongodb.net services and you need to setup freeService in databaseRoot: this.databaseRoot = { dev: "mongodb://localhost:27017" , prod: "mongodb://userAdmin:PUT_YOU_PASSWORD@localhost:27017/admin", freeService: "mongodb+srv://userAdmin:PUT_YOU_PASSWORD@cluster0.piqav.mongodb.net/masterdatabase?retryWrites=true&w=majority" };  .
• Cert setup on production (certPathProd): this.certPathProd = { pKeyPath: "/etc/letsencrypt/live/maximumroulette.com/privkey.pem", pCertPath: "/etc/letsencrypt/live/maximumroulette.com/cert.pem", pCBPath: "/etc/letsencrypt/live/maximumroulette.com/fullchain.pem" };

about server-config

Config property defined in constructor from ServerConfig class in interest way. With two defined flags dev & prod it is easy resolved boring problem with migration localhost - public server:

    // enum : 'dev', 'mongodb.net' or 'prod'     this.serverMode = "dev";      this.networkDeepLogs = false;     this.rtcServerPort = 12034;     this.rtc3ServerPort = 9001;     this.connectorPort = 1234;      this.domain = {       dev: "localhost",       prod: "maximumroulette.com"     };      this.masterServerKey = "maximumroulette.server1";     this.protocol = "http";     this.isSecure = false;      // localhost     this.certPathSelf = {       pKeyPath: "./server/rtc/self-cert/privatekey.pem",       pCertPath: "./server/rtc/self-cert/certificate.pem",       pCBPath: "./server/rtc/self-cert/certificate.pem",     };      // production     this.certPathProd = {       pKeyPath: "/etc/httpd/conf/ssl/maximumroulette.com.key",       pCertPath: "/etc/httpd/conf/ssl/maximumroulette_com.crt",       pCBPath: "/etc/httpd/conf/ssl/maximumroulette.ca-bundle"     };      this.appUseAccountsSystem = true;     this.appUseBroadcaster = true;     this.databaseName = "masterdatabase";      this.databaseRoot = {       dev: "mongodb://localhost:27017" ,       prod: "mongodb://userAdmin:********@maximumroulette.com:27017/admin"     };      this.specialRoute = {       "default": "/var/www/html/applications/visual-typescript-game-engine/build/app.html"     };

- Running server is easy : From root folder (not from server folder). If you wanna use node.js debugger you need to fix path for the certs.

  npm run rtc

With this cmd : npm run rtc we run server.js hosting and connector.ts websocket session and webrtc broadcaster.ts. Connector is our account session used for login, register etc. Implemented video chat based on webRTC protocol. Running rtc3 server is integrated. If you wanna disable session-database-rtc3 features and run only broadcaster:

Features comes with broadcaster:

• Multiplatform video chat works with other hybrid frameworks or custom implementation throw the native mobile application web control (Chrome implementation usually).

GUI Tools

To get GUI tools first download python3 for your OS. creator2dmap is python3 canvas oriented application.

 cd tools 
 git submodule init  
 git submodule update  
 // or  
 git clone --recurse-submodules https://github.com/zlatnaspirala/visual-ts-game-engine 
 // update   git fetch   git merge

In this way you will get project: https://github.com/zlatnaspirala/creator-2dmap intro tools/creator2dmap/ folder.

Start application with:

python.exe tool.py (win)   ./python3 tool.py (macos) 

Documentation:

Follow link for API: [WIP] Application documentation

Possible to install from (It's good for instancing new clear base project):

  npm i --save visual-ts 

Take a look this repo (it is example for approach npm i visual-ts) https://github.com/zlatnaspirala/visual-ts-module

Work with visualTs like package library will be full teste in next commits.

If you wanna generate doc you will need manual remove comment from plugin section in webpack.config.js. Restart 'npm run dev' Best way to fully healty build.

If you wanna insert some new html page just define it intro webpack.config.js :

plugins : [     new HtmlWebpackPlugin({     filename: '/templates/myGameLobby.html',             template: 'src/html-components/myGameLobby.html'         }), ...

• See register and login example.

Code format :

  npm run fix   npm run tslint

or use :

  tslint -c tslint.json 'src/**/*.ts' --fix   tslint -c tslint.json 'src/**/*.ts'

Abour visual tools

Based on python3 tk tech.It is standalone git project imported like git submodule.

https://github.com/zlatnaspirala/creator-2dmap

Important - About tools setup

After setup run python app from cli with command:

  npm run creator
