Glossary

Topic	Description
Introduction to 2D	Understand the available features of 2D projects in Unity.
Get started with 2D game development	Resources for creating 2D games in Unity.
2D renderer sorting	Understand how renderers determine priority in 2D projects.
SpritesA 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info See in Glossary	Use Sprites within your 2D game.
TilemapsA GameObject that allows you to quickly create 2D levels using tiles and a grid overlay. More info See in Glossary	Use the Tilemap system to create 2D levels.
2D physics	Use Unity’s physics system to handle physics 2D components.
2D game development in URP	Understand how to implement 2D lights, 2D lighting effects, and the pixelated visual style in your projects in URP.
