GodoMaster

Complete Godot 4.x game development skill: project setup, GDScript, scene architecture, 2D/3D, physics, animation, UI, audio, input, shaders, networking, performance, export, data persistence, localization, AI behavior, and asset pipeline.

When to Use

This Skill should be used when the task involves Godot game development — writing GDScript, designing scenes, implementing gameplay systems, debugging, or optimizing.

Must Use

This Skill must be invoked in the following situations:

• Creating or configuring a Godot project (renderer, settings, folder structure)
• Writing, reviewing, or debugging GDScript code
• Designing node hierarchies and scene composition
• Implementing 2D or 3D gameplay (sprites, tilemaps, meshes, cameras)
• Setting up physics (collisions, rigid bodies, raycasting)
• Creating animations (AnimationPlayer, Tween, AnimationTree)
• Building UI (menus, HUD, dialogs, themes)
• Adding audio (music, SFX, spatial audio, audio buses)
• Handling input (keyboard, mouse, gamepad, touch, remapping)
• Writing shaders (2D effects, 3D materials, post-processing)
• Implementing multiplayer/networking
• Exporting to platforms (Windows, Mac, Linux, Web, Mobile)
• Optimizing performance (profiling, draw calls, memory)
• Implementing save/load and file I/O
• Implementing localization or multi-language support (tr(), TranslationServer)
• Building AI behavior systems (state machines, behavior trees, utility AI)
• Working with the asset import pipeline (ResourceImporter, EditorImportPlugin, addons)
• Creating GDExtension modules (C++ integration, godot-cpp)

Quick Reference

GDScript Essentials

# File structure
extends CharacterBody2D
class_name Player

const SPEED := 300.0
signal health_changed(new_health: int)

@export var max_health := 100
@export_range(0, 100) var start_health := 100
@export_storage var internal_state: int = 0  # 4.4+ serialized but hidden

@onready var sprite := $Sprite2D
@onready var animation := $AnimationPlayer

var health: int
var velocity := Vector2.ZERO

func _ready() -> void:
    health = start_health

func _physics_process(delta: float) -> void:
    if not is_on_floor():
        velocity.y += gravity * delta
    if Input.is_action_just_pressed("jump") and is_on_floor():
        velocity.y = jump_velocity
    var direction := Input.get_axis("move_left", "move_right")
    velocity.x = direction * speed
    move_and_slide()

Localization Quick Pattern

# Localization
func _ready() -> void:
    label.text = tr("KEY_GREETING")
    count_label.text = tr_n("1 enemy", "%d enemies", count) % count
    TranslationServer.set_locale("zh_CN")

AI Quick Pattern

# Behavior tree tick pattern
func _physics_process(delta: float) -> void:
    behavior_tree.tick(self, blackboard)

# NavigationAgent avoidance (4.4+)
nav_agent.avoidance_enabled = true
nav_agent.set_velocity(desired_velocity)

Node Lifecycle Order

_init()           → Object created (before tree)
_enter_tree()     → Enters scene tree
_ready()          → All children ready (bottom-up)
_process()        → Every frame
_physics_process()→ Every physics tick
_exit_tree()      → Leaves scene tree

move_up/down/left/right → WASD + Left Stick
jump → Space / Gamepad A
attack → Left Click / Gamepad X
interact → E / Gamepad Y
