this fixes a race condition where if 2 goroutines try to send a packet at the same time, they could end up being malformed due to the 2 separate calls to peer.conn.Write(). instead of writing the packet size to peer.conn.Write() directly, we make space in buf for the packet size, and patch it in place. this lets us get away with only having 1 call to peer.conn.Write() which will ensure that the full packet is written properly and be goroutine safe :3 |

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.
Startup the environment using
$ chmod +x ./build.sh && ./build.sh
$ docker compose up
login server is hosted at 127.0.0.1:23000
, just join from your favorite 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.
