How To TileMaps in Unity in Unity: Best Guide

TileMaps in Unity, provides developers with a versatile set of tools to bring their visions to life. One crucial aspect of game design is creating environments, and a great way to achieve this is through the use of Tilemaps and Tile Palettes. In this guide, we’ll walk through the process of creating a Tilemap and Tile Palette in Unity, step by step.

TileMap Creation In Unity:

These are the following steps you need to follow in order to successfully make Tilemaps in unity:

1. Import Your Assets:

Start by importing your assets into Unity. If you’re working with pixel art, it’s recommended to set the filter from bilinear to no filter for a crisp look.

2. Adjust Pixel Per Unit:

Set the ‘Pixels Per Unit’ according to your preferences. For pixel art, matching this value to your art size (e.g., 16×16) is a good practice to maintain visual consistency for a tilemaps in unity.

3. Open Sprite Editor:

Click on ‘Open Sprite Editor’ to access the Sprite Editor window.

4. Slice Your Sprite:

In the Sprite Editor, click on ‘Slice’ and choose the ‘Grid by Cell Size’ option. Define the cell size, which should match your art size, and click ‘Apply’ to finalize the changes, to get one step closer on learning to create tilemaps in unity.

5. Create a Tile Palette:

Now it’s time to create a Tile Palette. Click on ‘Create New Tile Palette,’ give it a suitable name, and save it.

So, open the TilePallete Window from the windows section on the unity header:

6. Populate Your Tile Palette:

Drag your Tilemap image onto the Tile Palette window. Unity will automatically generate tiles based on the sliced sprite.

So, the first step is to click on create new Tile Palette, name it and save it somewhere relevant:

Then, drag your image you just sliced on the Tilemap window:

7. Explore Tilemap Features:

Select the Tilemap in the scene and start exploring the features of the Tilemap. Use the brush tool to paint tiles onto the scene and the eraser tool to remove them.

8. Add a Tilemap Collider:

With the Tilemap selected, add a Tilemap Collider to it. This will create individual colliders for each tile.

9. Optimize with Composite Collider:

For performance reasons, it’s recommended to add a Composite Collider to merge all the individual colliders into one. This helps reduce the number of separate colliders and improves efficiency.

10. Set Rigidbody to Static:

As the Composite Collider adds a Rigidbody component, change its body type to ‘Static’ to prevent unexpected physics interactions.

People Might Ask:

What is the purpose of a Tilemap in Unity?

Using a Tilemap in Unity, game creators can quickly and easily generate 2D worlds by organizing and painting individual tiles, which makes level design a lot easier.

Why is adjusting ‘Pixels Per Unit’ important when working with pixel art?

A consistent visual representation in Unity is ensured by setting the ‘Pixels Per Unit’ to match the pixel size of your artwork. This is especially important for pixel art, where preserving the original beauty is vital.

What is the significance of using a Tile Palette in Unity?

The Composite Collider reduces the computational overhead of managing several distinct colliders by combining individual tile colliders into a single collider. The overall performance of your Unity project is enhanced by this modification.

How does the Composite Collider enhance performance in a Tilemap?

The Composite Collider consolidates individual tile colliders into a single collider, reducing the computational overhead associated with handling numerous separate colliders. This optimization improves overall performance in your Unity project.

Can I customize the Tilemap further after creating it?

Yes, you may experiment with other features like brushes, erasers, and other tools inside the Tilemap system to further hone and personalize your gaming experience after creating your Tilemap.

Are there specific considerations when using Tilemaps for different art styles?

Although the basic concepts of Tilemaps are universal, the greatest visual results are guaranteed when the ‘Pixels Per Unit’ and tile sizes are adjusted according to the art style. To achieve the intended look, experimentation and fine-tuning are essential.

How do I troubleshoot issues with tile placement or collisions?

If you experience issues with collisions or tile placement, make sure that your collider configurations, grid settings, and “Pixels Per Unit” are all correct. For best results, make sure your tiles are sliced accurately and think about modifying the Composite Collider parameters.


Game creators need to know how to create Tilemaps in unity. This comprehensive guide will assist you in comprehending the procedure, ranging from asset import to collider optimization. Play around with various tile sizes, investigate more complex functions, and let your imagination run wild to create engaging gaming scenarios. Cheers to creating video games!
