Github repository

• New moons.

Looking for a successor !

Looking for a successor to keep LethalExpansion and LethalSDK alife.

Hello, making this mod was an awesome adventure, but today i want to work on other projects and explore some game concept ideas to see if i can make my own game. But i want deprecating this mod to be the last resort. It's why i'm looking for someone interesting into continuing this mod and make it in his name. If you are ever interested, invite me on discord with my username HolographicWings or write an issue either on LE or LSDK repositories.

Thanks you for supporting me during this project, i hope the LC modding will become even greater.

Usage :

Requirement :

• The SDK
• Unity (2022.3.9 Recommended)
• Unity Hub

How to install :

Tutorial video :

• Download the SDK. (LethalSDK.zip)
• Install both Unity and Unity Hub.
• In Installs tab in Unity Hub, locate the Editor executable in the Unity installation directory.
• Extract the SDK ("LethalSDK_Project" folder) anywhere.

How to use :

(I'll made a video tutorial)

• Open the "LethalSDK_Project" as a project though the Unity Hub
• Go in the Mods folder and duplicate the TemplateMod folder.
• Raneme it as the name of your new mod.
• Open this folder and click on the ModManifest file, change informations about your mod. WARNING : the Mod Name and the Mod Folder must be same !
• You can follow how the TemplateMod is made to make your own stuff. In the root of the project, you can find a scene called SceneBuilder, this scene is usefull to easily make your own moons, just make a prefab from the scene by drag and dropping the parent object to the file explorer.
• When your mod is finished, click on the LethalSDK tab in the top of Unity, then click on AssetBundle Builder, and finally click on Build AssetBundles. (The first building will be longer)
• When built, you can find your Asset Bundle in the folder you set, this Asset Bundle must be placed in the "Lethal Company\BepInEx\plugins\LethalExpansion\Modules" to be loaded. (Only the file with the name of your mod, the manifest is not required) WARNING : Of course, all players must have the same mods in order to join the same lobby.
