Status Effect Manager

Can be used to easily add new status effects to Valheim.

How to add status effects

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 StatusEffectManager.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)\StatusEffectManager.dll" />
        </ItemGroup>
        <ILRepack Parallel="true" DebugInfo="true" Internalize="true" InputAssemblies="@(InputAssemblies)" OutputFile="$(TargetPath)" TargetKind="SameAsPrimaryAssembly" LibraryPath="$(OutputPath)" />
    </Target>
</Project>

Make sure to set the StatusEffectManager.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 StatusEffectManager; to your mod and use the CustomSE class, to add your effects.

Example project

This adds a status effect from a bundle ,with and without a custom folder, and creates one in code. The se_toxicity asset bundle is in a directory called StatusEffects, while the se_drunk asset bundle is in a directory called assets. The folder assets is the default fallback if a custom folder is not defined.
