Unity 2D Development

2D Project Setup

Unity supports dedicated 2D project creation. When starting a 2D project:

• Select the 2D template (or 2D (URP) for 2D lighting support) when creating a new project
• The 2D template auto-installs required packages: 2D Sprite, 2D Tilemap Editor, 2D Animation
• The Scene view defaults to orthographic (top-down XY plane)
• The camera is set to Orthographic projection by default
• Imported images default to Sprite (2D and UI) texture type

Core 2D subsystems from the docs:

• Sprites: "2D graphic objects" -- the foundation for 2D games
• Tilemaps: "A GameObject that allows you to quickly create 2D levels using tiles and a grid overlay"
• 2D Physics: Dedicated physics system with 2D-optimized components
• 2D Rendering in URP: 2D lights, lighting effects, and pixelated visual styles
