▼CAttribute
▼CGearLib.API.Fields.IField	Interface for adding properties to their Part Behaviour in game for players. This uses the built-in existing properties available on Parts to customize them. MODDERS: Do not use this. Instead, use the other fields inheriting from this. Example below on how to use these fields: [IntField(label = "Timing", tooltip_text = "Offset degrees from TDC to fire piston", initial_value = 5, minimum_value = -30, maximum_value = 30)] public int timing;
CGearLib.API.Fields.BooleanField	A Boolean property for your Behaviour
CGearLib.API.Fields.FloatField	A Float property for your Behaviour
CGearLib.API.Fields.InputField	A Input property for your Behaviour. This is for Keyboard inputs
CGearLib.API.Fields.IntField	A Integer property for your Behaviour
CGearLib.API.Fields.JoystickField	A Joystick property for your Behaviour. Utilizes the base game functionality with controllers
CGearLib.API.Fields.StringField	A String property for your Behaviour
CGearLib.API.LinkType	Base class for a new Link Type in the game. Allows your mod Parts to connect together
CGearLib.API.Material

CGearLib.API.Part	Base class to use when creating a new Part. These can be created using: Part new_part = new Part(args); or by inheriting like so: class NewPart : Part { public NewPart() : base(args) { // Your code here } }
▼CPartBehaviourActivatableBase
CGearLib.API.Behaviour	Base class for a Behaviour to attach to your Part. Ideal usage is inheriting from this class (public class MyBehaviour : Behaviour {})
