2D Game Development

Principles for 2D game systems.

1. Sprite Systems

Sprite Organization

Component	Purpose
Atlas	Combine textures, reduce draw calls
Animation	Frame sequences
Pivot	Rotation/scale origin
Layering	Z-order control

Animation Principles

Frame rate: 8-24 FPS typical
Squash and stretch for impact
Anticipation before action
Follow-through after action

2. Tilemap Design

Tile Considerations

Factor	Recommendation
Size	16x16, 32x32, 64x64
Auto-tiling	Use for terrain
Collision	Simplified shapes

Layers

Layer	Content
Background	Non-interactive scenery
Terrain	Walkable ground
Props	Interactive objects
Foreground	Parallax overlay

3. 2D Physics

Collision Shapes

Shape	Use Case
Box	Rectangular objects
Circle	Balls, rounded
Capsule	Characters
Polygon	Complex shapes

Physics Considerations

Pixel-perfect vs physics-based
Fixed timestep for consistency
Layers for filtering

4. Camera Systems

Camera Types

Type	Use
Follow	Track player
Look-ahead	Anticipate movement
Multi-target	Two-player
Room-based	Metroidvania

Screen Shake

Short duration (50-200ms)
Diminishing intensity
Use sparingly

5. Genre Patterns

Platformer

Coyote time (leniency after edge)
Jump buffering
Variable jump height

Top-down

8-directional or free movement
Aim-based or auto-aim
Consider rotation or not

6. Anti-Patterns

❌ Don't	✅ Do
Separate textures	Use atlases
Complex collision shapes	Simplified collision
Jittery camera	Smooth following
Pixel-perfect on physics	Choose one approach

Remember: 2D is about clarity. Every pixel should communicate.
