A tilemapA GameObject that allows you to quickly create 2D levels using tiles and a grid overlay. More info
See in Glossary is a GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary which acts as a grid that you place your selected tiles on.
There are multiple types of tilemap, these are:
The default tilemap is Rectangular. Refer to the respective pages for Hexagonal and Isometric tilemaps for more information on their specific features and uses.
To create a tilemap asset, do the following:
After creating a tilemap, Unity creates a new Grid GameObject with a child tilemap GameObject in the sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary. The Grid GameObject determines the layout of its child tilemaps. The child tilemap consists of the Tilemap component and Tilemap Renderer component. Unity paints tiles onto the tilemap GameObject.
Note: If you don’t have these options in the menu bar, you may not have the 2D Tilemap Editor package installed. In this scenario, download the 2D Tilemap Editor package from the Package Manager.
You can also create a new tilemap from the Tile Palette window. To do this, do the following:
You can create additional tilemaps for a Grid with the following steps:
If the type of tilemap you select does not match the type of grid, you may encounter a dialog with a warning. For more information on how to handle this, refer to Troubleshooting mismatched Cell Layouts.
After creating the tilemaps, you can adjust the properties of the Grid GameObject to adjust the properties of its child tilemaps. This ensures consistency across all the child tilemaps of a Grid. These changes also affect attached components such as the Tilemap Renderer and Tilemap Collider 2D components.
