Godot GDScript Skill

GDScript programming for Godot Engine development.

Overview

This skill provides capabilities for implementing game logic using GDScript, Godot's Python-like scripting language.

Capabilities

Language Features

• Classes and inheritance
• Signals and connections
• Coroutines with await
• Static typing

Node Interaction

• Scene tree navigation
• Node references
• Group management
• Signal connections

Performance

• Object pooling patterns
• Cache node references
• Optimize loops
• Use typed arrays

Best Patterns

• State machines
• Singletons (autoload)
• Resource management
• Export variables

Prerequisites

• Godot 4.0+
• GDScript knowledge

Usage Patterns

Signal Pattern

class_name Player extends CharacterBody2D

signal health_changed(new_health: int)
signal died

@export var max_health: int = 100
var health: int = max_health

func take_damage(amount: int) -> void:
    health = max(0, health - amount)
    health_changed.emit(health)
    if health <= 0:
        died.emit()

Coroutine Pattern

func spawn_enemies() -> void:
    for i in range(10):
        spawn_enemy()
        await get_tree().create_timer(1.0).timeout

Best Practices

1. Use static typing
2. Cache node references in _ready
3. Use signals for decoupling
4. Prefer composition over inheritance
5. Profile with built-in profiler
