Tilemaps in Unity

Tilemaps are a useful thing for anyone trying to create a 2D game in Unity. They allow for quick and simple level building.

To get started open the Tile Palette window in Unity by going to the top left of the screen and clicking Window => 2D => Tile Palette and docking the window next to your scene view.

Create a Tilemap in the hierarchy by right-clicking and selecting 2D Object => Tilemap and rename it to something that will fit your project.

Now to create a new palette select the create a new palette option from the drop-down in the Tile Palette window.

With the new palette made go to your sprites and select the sets you want to use. Make sure to set the sprite mode to multiple, open the sprite editor, and make sure the sprites are sliced correctly.

Now you can pull the sprites into the palette and save them in the appropriate file.

Now you can paint them into the scene as you wish.
