This example shows how to apply the State machine programming pattern in GDscript, including Hierarchical States, and a pushdown automaton.

Language: GDScript

Renderer: GLES 2

States are common in games. You can use the pattern to:
1. Separate each behavior and transitions between behaviors, thus make scripts shorter and easier to manage
2. Respect the Single Responsibility Principle. Each State object represents one action
3. Improve your code's structure. Look at the scene tree and FileSystem tab: without looking at the code, you'll know what the Player can or cannot do.
