2D Essentials in Godot 4.3+

All examples target Godot 4.3+ with no deprecated APIs. GDScript is shown first, then C#.

Related skills: player-controller for CharacterBody2D movement patterns, animation-system for AnimatedSprite2D and sprite animation, physics-system for collision shapes and raycasting, camera-system for Camera2D follow and shake, shader-basics for 2D shaders and post-processing, godot-optimization for rendering and draw call tuning.

1. Canvas Layers and Draw Order

Draw Order Rules

Within a single canvas layer, nodes draw in scene tree order — nodes listed lower in the Scene panel draw on top. Use z_index to override without rearranging the tree.

# Draw this node above siblings (default z_index is 0)
z_index = 10

# Make z_index relative to parent (default: false = global)
z_as_relative = true

CanvasLayer

CanvasLayer creates a separate rendering layer with its own transform, independent of the camera. Higher layer values draw on top.

Layer	Typical Use
-1	Parallax backgrounds
0	Default game layer (all Node2D without CanvasLayer)
1	HUD / UI overlay
2	Pause menu, screen transitions

# Scene tree example
Main
├── ParallaxBackground (CanvasLayer, layer = -1)
│   └── Parallax2D
├── World (Node2D — default layer 0)
│   ├── TileMapLayer
│   └── Player
└── HUD (CanvasLayer, layer = 1)
    └── Control

Note: CanvasLayers are NOT required to control draw order. For objects within the same game world, use z_index or scene tree ordering. CanvasLayers are for elements that should be independent of the camera (HUD, parallax, transitions).

Canvas Transform

Camera2D works by modifying the viewport's canvas_transform. For manual control:

# Scroll the canvas directly (equivalent to camera movement)
get_viewport().canvas_transform = Transform2D(0, Vector2(-200, 0))

Coordinate Conversion

# Local to canvas (world) coordinates
var world_pos: Vector2 = get_global_transform() * local_pos
var local_pos: Vector2 = get_global_transform().affine_inverse() * world_pos

# Local to screen coordinates (accounts for camera, stretch, window)
var screen_pos: Vector2 = get_viewport().get_screen_transform() * get_global_transform_with_canvas() * local_pos

// Local to canvas (world) coordinates
Vector2 worldPos = GetGlobalTransform() * localPos;
Vector2 localFromWorld = GetGlobalTransform().AffineInverse() * worldPos;

// Local to screen coordinates
Vector2 screenPos = GetViewport().GetScreenTransform() * GetGlobalTransformWithCanvas() * localPos;

2. TileMap System

TileMapLayer (Godot 4.5+) is the modern API — one tilemap = one node = one layer. Drive painting with a TileSet resource (atlas + properties + physics + custom data). Use terrain autotiling for biome-aware tile selection, scene collection tiles for placing scene instances on tiles.

See references/tilemap.md for full TileSet setup, atlas / physics / terrain configuration, custom data on tiles, scene collection tiles, and the 4.5+ tile-collision-bump auto-merge fix.

3. Parallax Scrolling

Parallax2D (Godot 4.4+) replaces the older ParallaxBackground/ParallaxLayer pair. Set scroll_scale per layer (0 = static, 1 = follows camera 1:1, fractional values for depth). Add repeat_size for infinite tiling.

See references/parallax.md for Parallax2D setup, side-scroller layer example, infinite repeat, split-screen parallax, common mistakes.

4. 2D Lights and Shadows

PointLight2D and DirectionalLight2D cast lighting onto sprites — pair with a normal map for 3D-style shading or use additive-blend illumination on flat sprites. Cast shadows with LightOccluder2D.

See references/lights-and-shadows.md for node overview, PointLight2D properties, shadow settings, cull masks, occluders, 2D normal maps, pixel-art lighting tips, and additive-sprite fake-light tricks.

5. 2D Particle Systems

GPUParticles2D for high counts (≥ 50 particles, GPU-driven), CPUParticles2D for low counts or platforms without GPU support. Both share the same ParticleProcessMaterial interface; differences are mainly performance.

See references/2d-particles.md for the GPU-vs-CPU distinguishing choices, basic setup, ParticleProcessMaterial 2D properties, emission from textures, flipbook, visibility rect, common 2D recipes.

6. Custom Drawing

Override _draw() on any CanvasItem to draw lines, polygons, text, or arbitrary shapes. Call queue_redraw() to trigger a re-render (never call _draw() directly).

See references/custom-drawing.md for the _draw() method, redrawing patterns, full drawing-methods reference, default font usage, @tool editor preview, line-width gotchas.

Godot 4.7+: DrawableTexture2D — a runtime-drawable texture type — shipped experimental in 4.7 and is not yet recommended for production.

7. 2D Meshes

When to Use

MeshInstance2D replaces Sprite2D when large transparent areas waste GPU fill rate. The GPU draws the entire texture quad including fully transparent pixels — a mesh eliminates those.

Converting Sprite2D to MeshInstance2D

Select the Sprite2D
Menu: Sprite2D → Convert to MeshInstance2D
Adjust growth and simplification parameters
Click "Convert 2D Mesh"

Best candidates:

Screen-sized images with transparency
Parallax layers with irregular shapes
Layered images with large transparent borders
Mobile/low-end GPU targets

8. 2D Antialiasing

Per-Node Antialiasing (Recommended)

Many drawing methods support an antialiased parameter:

draw_line(Vector2.ZERO, Vector2(100, 50), Color.WHITE, 2.0, true)  # antialiased = true

// Equivalent in a CanvasItem subclass (e.g., a custom Control or Node2D):
public override void _Draw()
{
    DrawLine(new Vector2(0, 0), new Vector2(100, 50), Colors.White, width: 2.0f, antialiased: true);
}

Line2D has an Antialiased property in the inspector — set it via line2D.Antialiased = true in C# or as an Inspector toggle in the editor. This works by generating additional geometry — no MSAA needed.

⚠️ Changed in Godot 4.7: CanvasItem antialiased line drawing no longer adds the antialiasing feather. The feather made draw_line()-style lines appear thicker than intended, so antialiased lines render thinner after upgrading — projects that relied on the old look must draw a thicker width. See the 4.7 migration guide.

MSAA 2D

Available in Forward+ and Mobile renderers only (NOT Compatibility).

Project Settings → Rendering → Anti Aliasing → Quality → MSAA 2D

Levels: 2x, 4x, 8x.

MSAA affects	MSAA does NOT affect
Geometry edges (lines, polygons)	Aliasing within nearest-neighbor textures
Sprite edges touching texture edges	Custom 2D shader output
	Font rendering
	Specular aliasing with Light2D

For pixel art: Do NOT enable MSAA 2D — it blurs intentionally sharp edges. Use the per-node antialiased parameter selectively.

9. 2D Snapping and Pixel-Perfect

Editor Snapping

Three-dot menu in the 2D toolbar:

Grid Step — snap to grid (configure Grid Offset and Step)
Rotation Step — snap rotation to degrees
Smart Snap — snap to parent, node anchors, sides, centers, guides

Runtime Pixel Snap

For pixel-art games, enable pixel snapping to prevent subpixel jitter:

Node2D: Project Settings → Rendering → 2D → Snapping → Snap 2D Transforms to Pixel
Vertices: Project Settings → Rendering → 2D → Snapping → Snap 2D Vertices to Pixel
Controls: Project Settings → GUI → General → Snap Controls to Pixels

- [ ] TileSet has `Use Texture Padding` enabled to prevent texture bleeding
- [ ] Parallax2D textures have top-left at (0,0), not centered
- [ ] `repeat_size` matches actual texture dimensions
- [ ] `repeat_times` is increased if the camera can zoom out
- [ ] LightOccluder2D nodes are added to shadow-casting objects when shadows are enabled
- [ ] Light and occluder cull masks are configured to avoid unnecessary light calculations
- [ ] GPUParticles2D has a valid Visibility Rect (auto-generate via Particles menu)
- [ ] `queue_redraw()` is called when custom drawing state changes
- [ ] Collision shapes on tiles use the Physics Layer system, not manual CollisionShape2D nodes
