Setting up your C# project

You want to begin setting up a mod like usual. Unfortunately, I do not have the time right now to explain that. Take a look at this guide.

References

You will want to reference the following DLLS in your C# project:

• In Subnautica\Subnautica_Data\Managed:
  • Assembly-CSharp
  • Assembly-CSharp-firstpass
  • UnityEngine.AssetBundleModule
  • UnityEngine.AudioModule
  • UnityEngine.CoreModule
• DLLs from other mods:
  • ECCLibrary
  • SMLHelper
• In Subnautica\BepInEx\plugins\QModManager:
  • QModInstaller

In your patch file, make sure to add using ECCLibrary;.

Importing assets

Asset Bundles are a Unity feature which allows you to efficiently import and load assets at runtime. This is essential for adding models into the game.

You will want a static reference to your AssetBundle in your mod class. The first line in your Patch method should be where you set the reference to this. Go here to learn about loading an AssetBundle.

Audio

If your mod uses custom audio, in the next line you should access ECCAudio.RegisterClips to load all clips from your AssetBundle into ECC's audio list. For more info click here.

Note: The Unity audio system may soon become obsolete in terms of modding, as new methods are added into SMLHelprt for creating FMOD assets. With how ECC works though, using ECCAudio/Unity Audio at all is completely optional.

Example:

using QModManager.API.ModLoading;
using ECCLibrary;
using UnityEngine;
using System.Reflection;

[QModCore]
public static class QPatch
{
    public static AssetBundle assetBundle;

    [QModPatch]
    public static void Patch()
    {
        assetBundle = ECCHelpers.LoadAssetBundleFromAssetsFolder(Assembly.GetExecutingAssembly(), "deextinctionassets");
        ECCAudio.RegisterClips(assetBundle);

        //Patch creatures and stuff here
    }
}
