# GodoMaster

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

## 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

## Quick Reference

### GDScript Essentials

```gdscript
# 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

@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()
```

### Scene Composition Patterns

```
Player (CharacterBody2D)
├── CollisionShape2D
├── Sprite2D / AnimatedSprite2D
├── AnimationPlayer
├── Camera2D
├── Hitbox (Area2D) → CollisionShape2D
├── Hurtbox (Area2D) → CollisionShape2D
└── AudioStreamPlayer2D

Enemy (CharacterBody2D)
├── CollisionShape2D
├── Sprite2D
├── AnimationPlayer
├── NavigationAgent2D
├── DetectionArea (Area2D) → CollisionShape2D
└── StateMachine → IdleState, ChaseState, AttackState

HUD (CanvasLayer)
├── MarginContainer
│   ├── TopBar (HBoxContainer) → ScoreLabel, TimerLabel
│   ├── HealthBar (TextureProgressBar)
│   └── BottomBar (HBoxContainer) → HotbarSlots
```

### 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
```

### Collision Layers

```
Layer 1: Player    Mask: 2,3,4
Layer 2: Walls     Mask: (none)
Layer 3: Enemies   Mask: 1,2
Layer 4: Pickups   Mask: 1
Layer 5: Proj(PLY) Mask: 2,3
Layer 6: Proj(ENM) Mask: 1,2
```

### Common Autoloads

```
GameManager  → res://scripts/core/game_manager.gd
AudioManager → res://scripts/core/audio_manager.gd
SaveManager  → res://scripts/core/save_manager.gd
SignalBus    → res://scripts/core/signal_bus.gd
```

### Project Folder Structure

```
project/
├── scenes/  (world/, ui/, actors/, effects/)
├── scripts/ (core/, systems/, components/, ui/)
├── resources/ (data/, themes/, materials/)
├── art/ (sprites/, tiles/, audio/, vfx/)
└── addons/
```

### Renderer Selection

| Renderer | Best For |
|----------|----------|
| **Forward+** | Desktop, high-end visuals |
| **Mobile** | Mid-range, balanced |
| **Compatibility** | Low-end, web, old hardware |

### Input Actions (configure early)

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