In this video I show how we can use websockets to build a browser-based multi-player game that works on any device. I design the multi-player game with the server authoritative model where the game state is stored on the server. I use WebSockets as a communication medium for the game I am building.

19.06.2023Thanks for this very thorough tutorial. The first part cleared a few things up for me. I'm not sure why you are calling the coloured squares 'balls' though haha, that confused me for a bit

17.06.2023Awesome tutorial, definitely learned a lot!
However, I can't seem to figure out how to get this online. I can't simply put the code on a webhost like I've done with PHP focused apps because I need a SSL cert for the browser to trust my website. How would I go about attaching a certificate?

17.06.2023I also made a multiplayer game on node.js using socket.io. Those who want to try it out can do so at battletanks.io

17.06.2023@Hussein Thanks for the lovely tutorial i deployed this game in Heroku enabling secured web socket connection (with 2 players max limit) https://ball-game-frontend.herokuapp.com/ but it’s super slow on WSS where as super fast on local system. Is TLS the reason behind this? If so how come big companies runs websocket so smoothly. Also while playing the game i do get frequent websocket already closed error

17.06.2023How can I deploy a practice realtime project like this? I want to use a PaaS such as Google Compute Engine, but I haven't had any luck.

17.06.2023This was the only video I could find that helped me build a multiplayer pong game. Thanks so much. https://multiplayer-pong.netlify.app/
Sometimes the bandwidth all of a sudden slows way down. Besides improving my code by making the server-side less stateful, what else can I do? You did mention about saving state in a Redis instance, but I'm not sure if that would only help scalability or also the network bandwidth.

17.06.2023Hi! So I am at47:22 in your vid, but when I search localhost:9091 it just says:
'This site can't be reached. Localhost refused to connect'
Thanks for the vid!!!

17.06.2023hello, it's not enouqht, but i'm understood basics. You can write only
const payLoad = {
clientId,
gameId
}
without dublicate props with string

16.06.2023well, without technics for multiplayers games, It will never been a real multiplayer game, try to put on the cloud and really play with a ping at least 100ms, it will be very bad the player experience.

16.06.2023Any ideas or resources on how to create a score and timer for this game?

16.06.2023Why do we generate a clientId upon every websocket request? Shouldn't we only do that when the connection is opened? The way it's written right now, doesn't the client get a new ID every time they send a request to the websocket?
Edit: I understand now. wsServer.on("request") is only called when there is a request to create a connection. I was interpreting "request" to mean any kind of connection or message, but it's not that. Request specifically refers to a request to create a websocket connection. So in essence, the whole wsServer.on("request") bit is the connect() method from the design overview. Once that is called, it establishes the 3 other, independent event listeners that then listen to if the connection opens, closes, or a message is received. Hope this helps if anyone else got confused!

15.06.2023The beginning of this video was SOOOOOOOO helpful omg. As a beginner it's been so hard for me to capture what the code is actually doing when I follow tutorials but your explanations and illustrations really helped to clear up some confusions I had. Thank you!

15.06.2023getting -> Uncaught TypeError: webSocket is not a constructor during the 'connect code' implementation.. kindly advice..
jcebalaji
15.06.2023sorry my bad.. used const webSocket = require("websocket").createserver;
instead of const webSocket = require("websocket").server;
issue resolved

15.06.2023I implemented the code using socket.io and react js but now the problem is, suppose there are 2 groups, thats total 6 players, iam confused about the timeout function. wont it be good to clear the timeout after the game is finished. It will run even if the no players are playing. But the thing is timeout is a single instance for all the users even if there are 1000 groups or 1 groups. so is there another solution to this.
i tried to create a custom timeout for all the groups seperately but calling them doesn't fit the solution.
I find the best solution for me will be to send the event when the user clicked onto the cells instead of keeping a timeout functionality. It will create a load in the server however it solves the problem of timeout. totally confusedl….if i clear the timeout when a socket disconnects, it clears the timeout for all the other users as well even if they are not in the same group

10.06.2023What if I want to run multiple game lobbies at the same time? Do I just open a new port running a websocket for every lobby?
