This video explains how to create a real-time, multiplayer webapp or game in Node.JS using two main Javascript libraries: Socket.IO and Express.JS.

In this video I explained how to make a moving player appear on the screens of each person on the web browser, and how to control that player using unique player codes.

If you watched the entire video, thank you and I hope that it helped and that I explained details thoroughly.

Although you can move only your player, since the unique player code of each other person is not hidden or random, this method is breakable through the console. To fix this you can just add another variable into the players array that is a random number.
