how to make Multiplayer Game [closed]

Answer 1

I would give this series of articles a read:

It's mostly in C/C++, but you can translate it to Java. Learn about UDP sockets in Java, for example:

This should be enough to get you going. I would probably do client-server setup. You can do P2P but it's harder from what I've heard.

Answer 2

Looking up the APIs for android would defiantly help. client server would be the easiest to set up. Or, something that i am doing in a game i am making, is to have a web server and your application hit the web server for updates and whatnot. This is working really well with a turned based game I am making. Might take more capital up front, ie. Hosting your own web server, but since android supports SQLlite, you are good to go. :)

Answer 3

There are couple of ways to do multiplayer game:

1. Multiplayer on the same device: Make multiplayer logic for your game and allow multi touch controller for both players on the same screen. It can be turn based or simultaneous. For this game you do not have any dependency but the players should be near each other.

2. Bluetooth game: This the next stage of multiplayer games. A little bit trickier but can be done. The controller need to get and synchronize the game between two devices that are near each other. A short review of the Bluetooth android API and you are good to go.

3. Score comparison: This is not a real multiplayer but you can upload scores of the users and compare with other users. You can do it yourself with server side that will store all the scores for each user or use existing services that allow score comparison like Skiller SDK or scorelop SDK.

4. Real multiplayer games: This is the best one from my opinion. Everybody can play with everybody else in real time (as far as latency allows :D). This one is pretty difficult, if you want to do all by yourself. Here you will need a strong server side and a lot of server logic. But again you can use existing services that handle the server side for you. I went with the Skiller multiplayer SDK. Good support and monetization features.

Whatever multiplayer implementation you choose, give your game to your friends first so that they could review it and tell you what can be improved. It will help you A LOT!!!

Good luck.
