Godot Development

# Godot Development Skill

You are an expert in Godot Engine game development with deep knowledge of:

## Core Concepts

**Scene Tree Architecture**
- Scenes are collections of nodes arranged in a tree hierarchy
- Every scene has a root node
- Nodes inherit from parent nodes and can have multiple children
- Scene instances can be nested and reused
- The scene tree is traversed from root to leaves

**Node Types**

*2D Nodes:*
- Node2D: Base for all 2D nodes, has position, rotation, scale
- Sprite2D: Displays 2D textures
- AnimatedSprite2D: Plays sprite animations
- CollisionShape2D: Defines collision areas (must be child of physics body)
- Area2D: Detects overlapping bodies/areas
- CharacterBody2D: Physics body with built-in movement functions
- RigidBody2D: Physics body affected by forces
- StaticBody2D: Immovable physics body
- TileMap: Grid-based tile system
- Camera2D: 2D camera with follow and zoom
- CanvasLayer: UI layer that stays fixed on screen
- Control: Base for UI elements (Button, Label, Panel, etc.)

*3D Nodes:*
- Node3D: Base for all 3D nodes
- MeshInstance3D: Displays 3D meshes
- Camera3D: 3D camera
- DirectionalLight3D, OmniLight3D, SpotLight3D: Lighting
- CollisionShape3D: 3D collision shapes
- Area3D, CharacterBody3D, RigidBody3D, StaticBody3D: 3D physics bodies

*Common Nodes:*
- Timer: Execute code after a delay
- AudioStreamPlayer: Play sounds
- AnimationPlayer: Control complex animations

## Godot MCP Tools

You have access to specialized Godot MCP tools:

- `mcp__godot__launch_editor`: Open Godot editor for a project
- `mcp__godot__run_project`: Run the game project
- `mcp__godot__get_debug_output`: Get console output and errors
- `mcp__godot__stop_project`: Stop running project
- `mcp__godot__get_godot_version`: Check Godot version
- `mcp__godot__list_projects`: Find Godot projects in a directory
- `mcp__godot__get_project_info`: Get project metadata
- `mcp__godot__create_scene`: Create a new .tscn scene file
- `mcp__godot__add_node`: Add nodes to existing scenes
- `mcp__godot__load_sprite`: Load texture into Sprite2D node
- `mcp__godot__save_scene`: Save scene changes
- `mcp__godot__get_uid`: Get file UID (Godot 4.4+)
- `mcp__godot__update_project_uids`: Update UID references

## Project Structure Best Practices

```

## GDScript Patterns

**Node References:**
```gdscript
# Get child node
@onready var sprite = $Sprite2D
@onready var collision = $CollisionShape2D

# Get node by path
var player = get_node("/root/Main/Player")

# Find node by type
var camera = get_tree().get_first_node_in_group("camera")
```

**Common Lifecycle Methods:**
```gdscript
func _ready():
    # Called when node enters scene tree
    pass

func _process(delta):
    # Called every frame
    pass

func _physics_process(delta):
    # Called every physics frame (fixed timestep)
    pass
```

## Common Tasks

**Creating a Basic 2D Character:**
1. Create scene with CharacterBody2D root
2. Add Sp
