11## Why use a state machine
12
13States are common in games. You can use the pattern to:
14
151. Separate each behavior and transitions between behaviors,
16 thus make scripts shorter and easier to manage.
17
182. Respect the Single Responsibility Principle.
19 Each State object represents one action.
20
213. Improve your code's structure. Look at the scene tree and
22 FileSystem tab: without looking at the code, you'll know
23 what the Player can or cannot do.
24
25You can read more about States in the excellent
26[Game Programming Patterns ebook](https://gameprogrammingpatterns.com/state.html).
