Thank you for your interest in improving this mod. This document describes how to build the project and what we expect from contributions.
- Windows (the project targets
net10.0withSupportedOSPlatformWindows). - .NET SDK compatible with .NET 10 (see
TargetFrameworkinDeadCellsMultiplayerMod.csproj). - Dead Cells with DCCM (Dead Cells Core Modding API) installed for local testing.
- Optional:
DCCM_MDK_ROOTenvironment variable pointing at your DCCM MDK/tools folder if you need Steamworks references (Steamworks.NET,steam_api64.dll) resolved via the paths in the project file.
From the repository root:
dotnet build -c ReleaseOutput artifacts are produced under bin/Release/net10.0/ (and the packaged mod layout as configured by the DCCM MDK targets).
For iterative development with automatic install into your DCCM layout, use Debug configuration (AutoInstallMod is enabled for Debug in the csproj).
ModEntry.cs— mod entry point and lifecycle.Mobs/— mob synchronization, wire codecs, tracing.Ghost/— remote player ghost and related hooks.UI/— in-game UI.Resourcefile/lang/— localization (.po/.pot).server/— networking (NetNode, wire protocol).
- Open an issue or discuss a small, scoped change before large refactors.
- Fork the repository and create a branch focused on one feature or fix.
- Keep pull requests focused — avoid unrelated formatting, renames, or drive-by cleanups in files you are not changing for the task.
- Match existing style — naming, patterns, and comment density should match surrounding code.
- Build in Release before submitting; fix any new compiler warnings relevant to your change.
- Describe what changed and why in the PR description (plain language, complete sentences).
- Changes should be minimal and directly related to the stated goal.
- Do not delete unrelated comments or rewrite large sections without need.
- Prefer one clear code path over many special cases when possible.
- New user-facing strings belong in localization (
Resourcefile/lang/) when applicable.
There is no automated test suite in this repository. For gameplay changes:
- Run the game through DCCM with the mod loaded.
- For multiplayer, verify host and client behavior when you touch sync or networking code.
For DCCM installation and API documentation, see the official DCCM docs and GitHub:
