How do I do a Multiplayer Game Online?(HELP)

someone could help me, I would know how to make an online multiplayer game. is there any tutorial available, or someone could teach me how can i do?

YOu will have to do some searching online and most likely use ajax/json, etc... as Construct 2 does not have any built in multiplayer. But if you search the forums here, you will find others working on multiplayer games using different plugins and techniques.

could be a game like pong, two bars where each bar is controlled on a different computer, that kind of multiplayer that I want to try.
