An Introduction To Tilemap In Unity

2D game development in Unity is almost TOO easy with the “Tilemap Editor”!

You can create a grid and quickly/easily build out your level’s environment, place your enemies, objects, obstacles, etc in seconds! Let’s jump in.

The word “Tilemap” is given as a title to various “different” things and thus can prove a little confusing to those who are new to this so be warned.

Unity has a built-in feature called “Tilemap” which covers a lot of what you’ll need to build a tile-based game. The first way that you’ll be interacting with Tilemap is through the “Tile Palette”. To access this just click “Window>2D>Tile Palette”. You can dock this window wherever you like it.

The “Tile Palette” allows you to display your individual tiles and select from them as a painter might select a color from a palette. It also features access to various brushes and tools for quickly applying or removing your tiles within the various parts of your scene.

The “Active Tilemap” box is where you select which Tilemap you’d like to build on.
