Animancer's state machines are Generic so before you can make a StateMachine<TState> you need to define your base state type (to use as the TState parameter). The only requirement for a class to be used as a state in this system is to implement the IState interface, which means that states can be anything you want such as:

MonoBehaviour components attached to a scene object or prefab.
ScriptableObject assets in the project.
Or just regular C# classes.

Example

A base state class can be as simple as this:

public abstract class State : IState
{
    public virtual bool CanEnterState => true;

    public virtual bool CanExitState => true;

    public virtual void OnEnterState() { }

    public virtual void OnExitState() { }
}

Existing Types

Rather than implementing the entire interface from scratch every time, there are several base classes that can make your implementation simpler:

Class	Description
`State`	The `State` class used in the above Example is included in the system so you can simply Inherit from it so that you only need to `override` the members you actually want to use.
`DelegateState`	Implements `IState`, but rather than defining its own logic it simply has a Delegate for each of the members of that interface so you can assign them when creating the state.
`StateBehaviour`	Inherits from `MonoBehaviour` and implements `IState` to act as the base class for states that are attached as components on `GameObject`s. Its `OnEnterState` and `OnExitState` methods enable and disable itself respectively, allowing you to use the regular MonoBehaviour Messages like `OnEnable` and `OnDisable` to implement your state transition logic, as well as other messages like `Update` or `FixedUpdate` depending on the needs of each individual state. All of the State Machines examples use State Behaviours.
