Tilemap

The Tilemap component is a system which stores and handles Tile Assets for creating 2D levels. It transfers the required information from the Tiles placed on it to other related components such as the Tilemap Renderer and the Tilemap Collider 2D.

Use this component with the Grid component, or a parent Grid GameObject, to lay out Tiles on the associated Grid. When creating a Tilemap (menu: GameObject > 2D Object > Tilemap), Unity automatically creates a Grid GameObject and sets it as the parent of a child Tilemap GameObject.

To modify and place Tiles onto a Tilemap, open the Tile Palette (menu: Window > 2D > Tile Palette). Refer to the documentation on Tile Palette and Painting Tilemaps for more information.

Tilemap Workflow

Below is the general workflow to create and paint a Tilemap:

1. Create a Tilemap GameObject. A Grid GameObject is also created automatically in the process.
2. Create Tile Assets directly, or generate Tiles from Sprites.
3. Create a Tile Palette with selected Tile Assets.
4. Paint on a Tilemap with your Tile Palette.
5. Optionally, you can attach the Tilemap Collider 2D component to your Tilemaps to make them interact with Physics2D.

Unity also supports specialized types of Tilemaps such as Hexagonal and Isometric Tilemaps. Refer to the documentation on their respective pages for their specific workflows.

2D extras in GitHub

You can download examples of scripted Tiles and Brushes from the 2D Extra GitHub repository. Example projects with these scripted GameObjects are availalbe in the 2D Techdemos Github repository. For descriptions of the different scripts and usage information, refer to the README.md for each repository.
