Create a Tile Set

A Tile Set is an asset which helps you create a Tile Palette and other supporting assets to help you paint Tiles onto a TilemapA GameObject that allows you to quickly create 2D levels using tiles and a grid overlay. More info
See in Glossary.

Unlike a Tile Palette, the Tile Set keeps the references of the textures that create Tiles, and automatically updates both itself and the Tiles if the texture changes.

Use a Tile Set asset if your Tiles are directly correlated with the textures you use, and you don’t need a lot of customization for your Tiles and Tile Palette.

Create a TileSet Asset

To create a Tile Set asset, from the main menu, select Assets > Create > 2D > Tile Palette > New Tile Set.

Add sprite textures

To populate the Tile Set with your spriteA 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 textures, follow these steps:

1. Prepare your sprite textures using the Sprite Editor.
2. Select the Tile Set asset in the Project window.
3. In the InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
   See in Glossary window, open the Texture Sources dropdown.
4. To add a texture, select the Add (+) button.
5. Open the Element dropdown, then select the Texture picker (⊙) to choose a texture.

To customize generating tiles from each texture, select the Tile Template picker (⊙) to pair the Texture with a Tile Template Asset.

Adjust the grid

To adjust the grid of the Tile Palette, use the settings under the Palette Grid dropdown. You can set properties such as the cell layout or the cell size of the Tile Palette.

Atlas the textures

To atlas the Textures used in this Tile Set, follow these steps:

1. Check the Create Atlas toggle.
2. Change the Sprite Atlas settings as needed. For more information, refer to Sprite AtlasA utility that packs several sprite textures tightly together within a single texture known as an atlas. More info
   See in Glossary.
3. The sprite textures added in the Tile Set will be automatically added as “Objects for Packing” in the Sprite Atlas on Apply.

Using a Sprite Atlas to atlas the Textures can help improve the performance of Tilemaps painted with this Tile Set by reducing draw calls, and reducing visual artifacts from the edges of Sprites from the Textures used.

Apply changes

To apply changes you make to the Tile Set, select Apply.

Use the Tile Set as a Tile Palette

When you’ve finished making changes to the Tile Set asset, follow these steps to use the Tile Set as a Tile Palette:

1. Select Open Tile Palette Window.
2. Set the Active Palette dropdown to the Tile Set.

You can now start painting Tiles with your Tile Set.
