This page will help you install everything you need to use Unity for KSP2 modding.

Installing Unity

  1. Download Unity Hub from https://unity.com/download.
  2. Download Unity 2022.3.5f1 by clicking on the “Install this version with Unity Hub” link on this page: https://unity.com/releases/editor/whats-new/2022.3.5.

Initializing the Unity project

  1. Follow the instructions on this page: https://luxstice.notion.site/Creating-a-Unity-Project-dae1a51ab2a84fc4b5c5e1eeef4b90b3 but use Unity 2022.3.5f1 instead.

Configure the Unity project

Installing the addressables package

Unity doesn’t come with this package natively, so we need to install it first:

  1. Open the Package Manager by clicking Window>Package Manager in the toolbar at the top of Unity.
  2. This will open a new window where you can manage most of the packages in your project.
  3. Go where it says Packages: In Project and change that to Unity Registry.
  4. In the search bar, look for Addressables. Select it and click Install. It will show a couple pop-ups, and once it is finished, it will show a green checkmark next to the Addressables package version.

Importing ThunderKit

ThunderKit is a package for Unity, however it is not hosted in the official Unity package repository, so it needs to be installed directly from its GitHub repository.

  1. Go to Window>Package Manager and click on the + sign in the top left corner of the window that opens, after that click on Add Package from Git URL and paste https://github.com/PassivePicasso/ThunderKit.git#at3-update and click Add.
  3. The ThunderKit Settings window should open, if it doesn’t, just go to Tools>Thunderkit>Settings in the toolbar at the top of Unity.
  4. Go to Import Configuration and in Import Project Settings, change the dropdown to Everything.
  5. Go to ThunderKit Settings and in Locate and load game files for project, click on Browse and select your main Kerbal Space Program 2 executable (KSP2_x64.exe).
  6. Click Import and wait for KSP2 to be imported. If asked, click I made a backup, Go Ahead.
  7. If Unity asks you to restart your project to disable the assembly updater, click Restart Project. It may ask you a second time after the import is finished, this time do not restart.
  8. To check if the game was correctly imported, select or create any game object, and in the inspector click Add Component and search for Core Part Data.
Sometimes, the component wont appear right after the import, if so:
Skip to the step for Importing KSP2 Unity Tools, and use the Tools/Fix Unity button.
You will also need to use this button if the KSP2 components on your objects break, displaying a yellow warning triangle. With Unity 2022, this seems to happen on almost every Unity restart.

Importing Unity KSP tools

  1. Go to Window>Package Manager and click on the + sign in the top left corner of the window that opens, after that click on Add Package from Git URL and paste https://github.com/KSP2Community/KSP2UnityTools.git and click Add.
If you already had an earlier version installed, you will need to delete the whole "KSP2UnityTools" folder from your Assets folder and then do the installation.

Setting up swinfo.json and addressables

  1. After installing KSP2UnityTools, go to Tools>KSP2 Unity Tools.
  2. Follow one of two following steps, depending on which applies for you:
  3. If you have a mod you want to copy addressables into:
    1. Select "Copy Assets Only" as the Build Mode.
    2. In the build path select the addressables for your mod.
    3. At the bottom of the window, press Import swinfo.json and select your mods swinfo.json.
  4. If you want to build a full mod from Unity:
    1. Set Build Mode to "Everything".
    2. Set build path to where you want to output your packaged mod (you can set this later, just set it before build).
    3. If you already have a swinfo.json file, you can skip the next steps using the import swinfo.json button as described in the previous section.
    4. Input your mod's ID (this is critically important).
    5. Setup the rest of your mod's info (these correspond to the swinfo).
  5. After doing one of the previous two processes, press Set Up Addressables From Mod Info, and it should automatically set up the addressables groups for you.
