Converts Godot 3.x shader code to Godot 4.x shader syntax. Updates SCREEN_TEXTURE to screen_texture uniform, DEPTH_TEXTURE to depth_texture uniform, texture() function changes, built-in varyings updates, and light function signature changes. Essential for rendering and visual effect migrations.
Use when creating Godot Editor plugins with custom docks, panels, and tools. Generates plugin.cfg configuration, EditorPlugin script templates, custom editor UI components, and integrates with ProjectSettings. Creates complete plugin structure following Godot 4.x best practices.
Use when handling input in Godot 4.x projects and need to modernize patterns. Generates Input Map configurations from hardcoded key checks, sets up joypad rumble (Godot 4.x feature), implements gyroscope/accelerometer input on mobile, creates context-sensitive input handling for different game states, and adds input buffering for responsive gameplay. Converts old InputEvent patterns to modern Godot 4.x best practices.
Optimizes Godot 4.x rendering pipeline including renderer selection, 2D batching, occlusion culling, LOD configuration, draw call reduction, and material/shader optimization. Detects rendering bottlenecks and applies targeted optimizations for 60+ FPS performance.
Use when setting up AnimationTree nodes for state machine-driven animation, creating AnimationNodeStateMachine graphs, configuring BlendSpace2D/3D for locomotion blending, implementing state transition conditions, or creating animation blend trees for complex animation mixing. Supports player character animations, NPCs, and complex animation systems.
Use when configuring audio bus hierarchies in Godot, setting up AudioStreamPlayer pooling for performance, implementing 3D spatial audio, adding audio effect chains like reverb and EQ, or creating music crossfade systems. Provides complete audio architecture patterns for games with multiple audio categories and dynamic mixing.

Modernizes Godot 3.x UI scenes and scripts to Godot 4.x best practices.
Before (Godot 3.x):
# Hardcoded in each Control node
$Button.modulate = Color.red
$Button.get("custom_styles/normal").bg_color = Color.blue
$Label.add_font_override("font", preload("res://fonts/big.tres"))
After (Godot 4.x):
# Centralized in Theme resource
# Create: res://ui/themes/main_theme.tres
# Assign to root Control or project settings
Theme.tres structure:
Theme
├── Button/styles/normal (StyleBoxFlat)
├── Button/colors/font_color = Color(1, 1, 1, 1)
├── Button/fonts/font = preload("res://fonts/button_font.tres")
├── Label/fonts/font = preload("res://fonts/label_font.tres")
└── Panel/styles/panel (StyleBoxFlat)
Before:
# Manual positioning
$Panel.position = Vector2(100, 100)
$Panel.size = Vector2(400, 300)
After:
Control (root)
├── Layout Mode: Anchors
├── Anchor Left: 0.5, Anchor Top: 0.5
├── Anchor Right: 0.5, Anchor Bottom: 0.5
├── Grow Horizontal: Center
├── Grow Vertical: Center
└── Custom Minimum Size: (400, 300)
Anchor Presets for Common Layouts:
| Layout | Anchors | Offsets | Grow |
|---|---|---|---|
| Fullscreen | 0,0 to 1,1 | 0 all sides | Both |
| Top Bar | 0,0 to 1,0 | Bottom: 60 | Horizontal |
| Bottom Bar | 0,1 to 1,1 | Top: 60 | Horizontal |
| Center Panel | 0.5,0.5 | Size defined | Both |
| Left Sidebar | 0,0 to 0,1 | Right: 250 | Vertical |
| Right Sidebar | 1,0 to 1,1 | Left: 250 | Vertical |
Project Settings:
Display > Window > Stretch
├── Mode: canvas_items (or viewport)
├── Aspect: expand
└── Scale: 1.0 (auto-detected)
Script for Dynamic Scaling:
func _ready():
# Handle hiDPI on different displays
var screen_dpi = DisplayServer.screen_get_dpi()
if screen_dpi > 150:
get_tree().root.content_scale_factor = 2.0
Responsive Sizing:
@export var base_width: float = 1920.0
@export var base_height: float = 1080.0
func _on_viewport_size_changed():
var viewport_size = get_viewport().get_visible_rect().size
var scale_x = viewport_size.x / base_width
var scale_y = viewport_size.y / base_height
scale = Vector2(min(scale_x, scale_y), min(scale_x, scale_y))
Deprecated Godot 3.x:

Script Integration:
@onready var rich_label: RichTextLabel = $RichTextLabel
func append_colored_text(text: String, color: Color):
rich_label.append_text("[color=%s]%s[/color]" % [color.to_html(), text])
func append_url(text: String, url: String):
rich_label.append_text("[url=%s]%s[/url]" % [url, text])
func _on_meta_clicked(meta):
OS.shell_open(str(meta))
Custom Button with Built-in Theme:
@tool
class_name ModernButton
extends Button
@export var button_style: ButtonStyle = ButtonStyle.PRIMARY:
set(value):
button_style = value
_update_style()
enum ButtonStyle { PRIMARY, SECONDARY, DANGER }
func _ready():
_update_style()
func _update_style():
match button_style:
ButtonStyle.PRIMARY:
add_theme_color_override("font_color", Color(1, 1, 1))
add_theme_stylebox_override("normal", preload("res://ui/styles/primary_normal.tres"))
ButtonStyle.SECONDARY:
add_theme_color_override("font_color", Color(0.2, 0.2, 0.2))
add_theme_stylebox_override("normal", preload("res://ui/styles/secondary_normal.tres"))
ButtonStyle.DANGER:
add_theme_color_override("font_color", Color(1, 1, 1))
add_theme_stylebox_override("normal", preload("res://ui/styles/danger_normal.tres"))

Using RectPosition/RectSize directly:
# ❌ Bad - breaks with different resolutions
$Control.rect_position = Vector2(100, 100)

# ✅ Good - use anchors and layout containers
# Set anchors in editor or use custom_minimum_size
$Control.custom_minimum_size = Vector2(200, 150)
Hardcoding pixel values without scaling:
# ❌ Bad - too small on hiDPI
var padding = 10
# ✅ Good - scale with content_scale_factor
var padding = 10 * get_tree().root.content_scale_factor
Manual font size calculations:
# ❌ Bad - inconsistent across displays
label.add_theme_font_size_override("font_size", 24)
# ✅ Good - use theme with dynamic fonts
# Set in Theme resource with multiple sizes
Forgetting to handle window resize:
# ✅ Good - subscribe to resize signal
