MMO Dragon Game Framework

Proof of concept networking entities and load balancing with distributed server workers.

Warning

Slowly and surely improving but probably not ready for a big game yet. Under heavy development.

Tech

• C# Core
• Lidgren Networking
• MessagePack for Serialization

Features

• Central server that handles message passing between the client and server workers.
• An entity data store. Entities are the dynamic objects in the server. Entities have a list of data including position, type, and any game data needed.
• MessagePack for message passing to the client and server.
• Example Unity3d client and server.

Future Work

• Better area entity checkouts.
• Multiple server workers for distributed processing.

Getting Started

1. Open the Unity Project at Workers/UnityMmo.
2. Open the scene Scenes/SampleScene.unity.
3. Run the sever from the tool bar Dragon GF/Run Server (Local).
