GDScript supports various data types, including integers, floats, strings, booleans, and specialized types like Vector2, Rect2, and Color․ Variables are declared using var or let, with onready for node references․ Operators include arithmetic (+, -), comparison (==, !=), logical (and, or), and assignment operators․ The as keyword enables type casting, while enums and null values simplify data handling․ GDScript’s dynamic typing makes variable management flexible and intuitive for developers․
String interpolation and built-in functions like str and int enhance data manipulation․ These features make GDScript accessible for beginners while maintaining robust functionality for complex game development tasks․
Node-Based Architecture in Godot 4
Godot 4 uses a node-based architecture, where scenes and nodes form a hierarchical structure․ Nodes can be extended with GDScript, enabling modular and reusable game components․
4․1 Understanding Scenes, Nodes, and the Node Tree
In Godot 4, scenes represent individual game levels or screens, while nodes are the building blocks within these scenes․ The node tree, visible in the Scene tab, organizes nodes hierarchically․ Each node can be a sprite, script, or other game object․ Nodes communicate through signals and callbacks, enabling interaction․ This structure simplifies game logic and enhances scalability․ Understanding scenes, nodes, and their relationships is crucial for effective game development in Godot 4, allowing developers to manage complexity and create modular, reusable components efficiently․
4․2 Extending Nodes with GDScript
Nodes in Godot 4 can be extended using GDScript to add custom behaviors and functionality․ By attaching scripts to nodes, developers can define how they interact with the game world․ Scripts can handle signals, such as user input or collisions, and modify node properties dynamically․ Inheritance allows scripts to extend base node classes, creating reusable components․ This approach enables developers to build complex game mechanics while keeping code organized and maintainable, leveraging GDScript’s simplicity and integration with Godot’s node system for efficient game development workflows․
Scripting Game Logic
