This is a simple mod skeleton to stat making mods in Spacefligth Simulator
Note: If you don't know about programming, c# language and Unity. Please first go learn about it.
First of all, you need to get Visual Studio Community, you can download it from this Link. When it is installing it will ask you to install workspaces, you need to install .Net Desktop Development, you also need to install .NET Framework 4.8 SDK in the Individual Components tab.
Note: Here there is an official Visual Studio installation guide
Next, you need to go to the Spaceflight Simulator Game\Spaceflight Simulator_Data\Managed folder and copy the following list of files to the Dependencies folder in this project:
- 0Harmony.dll
- Assembly-CSharp.dll
- Newtonsoft.Json.dll
- UniTask.dll
- UnityEngine.CoreModule.dll
- UnityEngine.dll
- UnityEngine.UI.dll
- UnityEngine.UIElementsModule.dll
- UnityEngine.UIModule.dll
Finally, you need to create a copy of env.props.example and name it env.props. Inside the file you need to change the ModsFolder variable to the path where you have your mods folder. This is used to automatically start your game when you compile the Mod. Now you can double click on MorePartsInstaller.sln and Visual Studio will open the project and if everything is ok and there are no errors you can hit Run to start the game with your mod
Note: If you want to change the project name to the name of your mod, change "MorePartsInstaller" in every file name, folder name and text in this project.
Once you have the project installed and can run it in-game, you can start making your mod. You will need a handy tool called dnSpy, this tool is used to view the game code in Assembly-CSharp.dll (all SFS functionality is in this file). You can download dnSpy at this link. To use it, you just need to open Assembly-CSharp.dll and dnspy will start reading the file and show you all the game code. The game code is useful to see how the game works and to see where you need to tweak to add your mods.
Modifications are done by Harmony patch, so you don't need to modify Assembly-CSharp.dll to add your modification. to learn about Harmony at this link.
The entry point (first thing to load into your mod) is the MyMod.cs file, you can start writing your code here. I added comments to guide you and links that can help you. If you have questions about something, you can write about it in the Discussions tab in this repository or go to SFS dicord server and write in modding channel.
