Creating a Tile Palette

Place a selection of Tiles onto Tile Palettes so that you can pick Tiles from the Palette to paint on Tilemaps. To create a Tile Palette, open the Tile Palette window by going to Window > 2D > Tile Palette. If you do not have this option, then the 2D Tilemap Editor package may not be installed. If so, download the 2D Tilemap Editor package from the Package Manager.

The Tile Palette window is empty by default. Select the New Palette drop-down menu to open a list of Tile Palettes available in the Project, or for the option to create a new Palette. Select the Create New Palette option to create a new Palette.

Select the Create New Palette option from the drop-down menu.
Select the Create New Palette option from the drop-down menu.

Use the ‘Brush’ drop-down menu to change the active Brush from the ‘Default Brush’ to other Brushes, such as Scriptable Brushes.

プロパティー 機能
Script Displays the currently assigned script Asset that provides a fixed set of APIs for Tilemap painting. The default is the GridBrush. Users may use or create their own Scriptable Brushes which become available from the drop-down menu. The Script property updates to reflect the current active Brush.
Can Change Z Position Enable this property to change the z-position of the active Brush. Disable to prevent any changes to the current z-position of the active Brush.
Z Position Only available when Can Change Z Position is enabled. Enter the desired z-axis value (only whole numbers) for this Brush when painting Tiles, which also adjusts the relative heights of Tiles on a Z as Y Isometric Tilemap . Refer to Adjusting the Tile height in the Palette for more information.

Tile Palette の編集

The tools for picking and painting with Tiles can also be used to edit the Tile Palette directly, allowing you to move and manipulate the Tiles currently placed on the Tile Palette. Select the Palette you want to edit from the ‘Palette’ drop-down menu, then click Edit to unlock the Palette for editing.

Refer to the documentation on Painting on Tilemaps for the shortcuts and functions of the Palette tools which are available for editing the Palette as well.

Creating Palette Assets from existing Grid Prefabs

You can convert an existing Prefab to a Palette Asset, so that you can use it in the Tile Palette window. To do this, the Prefab must not already be a Palette Asset, and it must have a Grid component on its topmost GameObject.

To convert a Prefab, drag and drop it onto the Tile Palette toolbar (highlighted in the image above). The Editor automatically converts it to a Palette Asset, and adds a Grid Palette Asset. The new Palette Asset has the same name as its source, and you can select it from the Palette drop-down menu.

Tile Palette Gizmos

The Tile Palette can display icons (Gizmos) over the current Palette Asset, to help you visualize specific criteria. For example, you can add a Gizmo that displays a special icon for Tiles that contain no Sprites.

To display the default Unity and the Palette Asset’s Gizmos on the Tile Palette, enable the Gizmos toggle (highlighted in the image above). The Tile Palette immediately displays any component with MonoBehaviour.OnDrawGizmos() in the Palette Asset.

To add a component with DrawGizmo to the Palette Asset:

  1. Select the Palette Asset in the Project window.

  2. Open the Palette Asset in Prefab Mode.

  3. Add the component while in Prefab Mode.

  4. Save the Asset while in Prefab Mode.

  5. Exit Prefab Mode.
