gopenfusion
A toy implementation of the Fusionfall Packet Protocol written in Go.
Landwalker demo
An implementation of a landwalker server is located in login/ && shard/. This includes a functional login server and a dummy shard (supporting the minimum amount of packets necessary). The DB implementation in core/db/ matches the OpenFusion 1.4 SQLite tables, which the login server uses. There's no support for NPCs nor other players, and is liable to softlock the client.
Generating structures
Dump and decompile the Assembly - CSharp.dll assembly from the fusionfall main.unity3d, using a tool like ilspycmd. The full output source can then be passed to genstructs.py script located in tools/, which will handle scraping constants and calculating structure padding. See the script for details on usage.
