Godot GDScript Development

Comprehensive guide for Godot 4.x game development using GDScript.

Core Principles

Node-Based Architecture

Everything in Godot is a Node. Scenes are trees of nodes. Understand the hierarchy:

• Node - Base class, provides basic tree structure
• Node2D - Adds 2D transform (position, rotation, scale)
• Node3D - Adds 3D transform
• Specialized nodes inherit from these

Scene Structure

• Scenes are reusable - A scene can be instanced multiple times
• Composition over inheritance - Build complex objects from simple scenes
• Each scene has a root node - The top-level node defines the scene type
