Simple yet advance state machine for Godot 4

Please Donte if this proves to be helpful.

Overview

Introducing the Super Expandable Finite State Machine (FSM) System for Godot 4! Designed for developers who want a robust and modular approach to managing complex character behaviors, this system is perfect for any game project, from simple platformers to complex RPGs.

Features

• Modular Design: Easily add new states with minimal effort. The system is built to be flexible and extendable.
• State Interface: A base state class defines a clear interface, ensuring consistency and simplifying the creation of new states.
• Centralized Management: The FSM node handles state transitions and updates, keeping your code clean and organized.
• Shared Properties: The Player node holds common properties and methods, making it easy to manage shared data across different states.
• Built-in States: Includes essential states like Idle, Walk, Jump, and Fall, with clear examples to help you get started.

How It Works

1. FSM Node: This central node manages all state transitions and updates. It ensures that only one state is active at a time and handles the logic for entering and exiting states.
2. State Nodes: Each state is a separate node that extends the base State class. This modular approach allows for easy addition of new states.
3. Player Node: Contains shared properties such as speed, gravity, jump force, and methods to update the player's velocity and handle jumps.

Integration Steps

1. Create the Player Node:
   • Create a CharacterBody2D node named Player and attach the Player.gd script.
2. Add the FSM Node:
   • Add a Node as a child of the Player node, name it FSM, and attach the FSM.gd script.
3. Create State Nodes:
   • Add child nodes under the FSM node for each state (IdleState, WalkState, JumpState, FallState) and attach the respective scripts.
4. Set the Initial State:
   • Select the FSM node and set the initial_state property in the Inspector to the desired initial state (e.g., IdleState).

Why Use This FSM System?

• Flexibility: Adapt the system to fit any game genre or character behavior.
• Maintainability: Clear separation of concerns makes your code easier to manage and debug.
• Scalability: Effortlessly add new states and behaviors as your game grows.
