Hello, Recently I have been working on a 2d sidescroller and have finished the singleplayer story mode but want to add kind of a multiplayer mode to play with friends. It is all coded in html5 using the canvas feature. I will provide a download link to it. When you open it, open the html file called "Multiplayer test". I already have the basic player movement and knife attack and scroll wheel weapon swtich, but before i go any further i would like to learn how to actually set up the multiplayer aspect. Any help would be much appreciated. Download: http://www.mediafire.com/download/59x822j4e60gkau
