Piece Manager

Can be used to easily add new building pieces to Valheim. Will automatically add config options to your mod and sync the configuration from a server, if the mod is installed on the server as well.

How to add pieces

Copy the asset bundle into your project and make sure to set it as an EmbeddedResource in the properties of the asset bundle. Default path for the asset bundle is an assets directory, but you can override this. This way, you don't have to distribute your assets with your mod. They will be embedded into your mods DLL.

Merging the DLLs into your mod

Download the PieceManager.dll and the ServerSync.dll from the release section to the right. Including the DLLs is best done via ILRepack (https://github.com/ravibpatel/ILRepack.Lib.MSBuild.Task). You can load this package ( ILRepack.Lib.MSBuild.Task) from NuGet.

If you have installed ILRepack via NuGet, simply create a file named ILRepack.targets in your project and copy the following content into the file

<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Target Name="ILRepacker" AfterTargets="Build">
        <ItemGroup>
            <InputAssemblies Include="$(TargetPath)"/>
            <InputAssemblies Include="$(OutputPath)\PieceManager.dll"/>
            <InputAssemblies Include="$(OutputPath)\ServerSync.dll"/>
        </ItemGroup>
        <ILRepack Parallel="true" DebugInfo="true" Internalize="true" InputAssemblies="@(InputAssemblies)"
                  OutputFile="$(TargetPath)" TargetKind="SameAsPrimaryAssembly" LibraryPath="$(OutputPath)"/>
    </Target>
</Project>

Make sure to set the PieceManager.dll and the ServerSync.dll in your project to "Copy to output directory" in the properties of the DLLs and to add a reference to it. After that, simply add using PieceManager; to your mod and use the BuildPiece class, to add your items.

Example project

This adds three different pieces from two different asset bundles. The funward asset bundle is in a directory called FunWard, while the bamboo asset bundle is in a directory called assets.
