This library is designed for implementing submarines in mods for the game Subnautica. If that is not what you're doing, then this package is not for you.
To use the library, you will need to add it to your Unity project that is using Thunderkit.
The components you need will depend on the sub you are making, but some of the more versatile components are the Spawn____ ones, which spawn and assign elements of the Cyclops to your sub.
There are some components in this library that replace ones that you might find on subs such as the Cyclops. One of the most notable ones is the ModdedSubFire replacing SubFire.
This is to provide more flexibility and to remove stuff like the use of enums, which limit expandability.
This library also comes with a custom save system for your subs. Simply add the SubSerializationManager to your prefab root, and then create a class for your save data
extending either ModuleDataClass or BaseSubDataClass.
Then in the Save Data Type Class Name field on the manager put in the full Type of your save data class (I.e. Chameleon.SaveData.ChameleonSaveDataClass).
The manager will also call any ISaveDataListener or ILateSaveDataListeners on save and load. These methods provide a BaseSubDataClass and you will need to cast it to your data class.
If the data isn't your data class (I.e. the cast is null) it means your sub doesn't have save data yet. I recommend making an extension method for BaseSubDataClass which ensures that your data isn't null and casts it to your data type.
Many fields accessible on components in this library have tooltips on them. If you're ever confused about what something does try hovering over its name in Unity to see if it has any extra info there.
You will need to go into the Configuration.targets file and change the CommonDir to the path to your Steam library folder so that the project builds correctly.
