Abstract - Java game
The purpose of this project is to simply try and see how easy or difficult it can be to create a working multiplayer game in java. This paper includes the programming process for the different parts of the game, such as the game client, lobby window, a high score and more.  Some details on how to create the character models, terrain and backgrounds is also included. The game mentioned is a side scroller and is made entirely in 2D and can be played in multiplayer together with up to fifteen players across the local network or the internet. We found out through hard work that creating a game is a lot harder than it looks. Collision detection is the hardest part to implement because of the complexity it requires. The results show what parts should receive the most attention and what there is to be learned more about.

Purpose
The foundations of this report is based on the creation of a side-scroller game. This game can be played cooperatively by up to 15 players from various geographical locations over the internet.

Scope
Our project team used the Java programming languish with Eclipse as the developer platform. For graphics and animations we are used Photoshop and Gimp. The in game sounds and music were rendered in a software that handles mp3 files.
In this report you will found out about how we managed to handle the different tasks  needed to get a game like this running. The different tasks is communication between clients and a server, graphic and sound management and at last a high score database.

Results
The game is fully playable and a bit addicting as we aimed for. There was a bit of struggle to get our in game animations to run smooth, but after deep researches we managed it. We also have some difficulties with the synchronization system, so that all clients was at the same part of the level.
