In this video, we're going to make a simple online multiplayer game from scratch with HTML, CSS, vanilla JavaScript and Firebase. You can take these concepts and apply them to whatever front end framework you like to use (React, Vue, Angular, etc).
We'll also cover some top down movement, sprites, basic collisions, and score upticking. Hope you enjoy working with Firebase!
Code download link (You'll need to set up a Firebase app to use it. Please read the notes in the security-rules file!):
