Pocket Tanks的WiFi大堂如何工作？

Question

There's a game called Pocket Tanks. What it offers is that 2 players can connect to same WiFi Network (like in home) and play the game together. Its different from internet multiplayer. It just needs common WiFi. I want to know how to implement such a system in my android game. I've tried to search it on Google but no helpful results. Any idea where do I even begin?

Thanks.

Answer 1

The app probably has a socket open listening on a certain port. Then when it searches for other phones, it just tries to connect to other IP addresses on that port.
