In Unity, tile maps are a popular way to create levels with repeating patterns of textures, such as floors and walls. This article will guide you through the process of adding tilemaps in Unity step by step.
Setting up a New Tilemap Asset
- Open Unity and create a new project or open an existing one.
- In the Project window, right-click and select “Create” > “Tilemap”.
- A new tilemap asset will be created in the Project window. You can rename it to something more descriptive if you prefer.
- Double-click on the tilemap asset to open it in the Tilemap Editor.
Creating Tiles
- In the Tilemap Editor, click the “New” button in the toolbar at the top of the window.
- A new tile will be created in the editor. You can select it and drag it around to position it on the grid.
- To change the texture of a tile, right-click on it and select “Set Tile”. Choose a texture from your project or import a new one.
- You can also adjust the size of a tile by selecting it and using the resizing tools in the toolbar.
Adding Layers
- To add additional layers to your tilemap, click the “New Layer” button in the toolbar.
- A new layer will be created, and you can start adding tiles to it using the same process as before.
- You can also change the order of layers by selecting a layer and dragging it up or down in the Layers panel on the right side of the editor.
Exporting the Tilemap
- Once you have finished creating your tilemap, click the “Apply” button in the toolbar to save your changes.
- In the Project window, select the tilemap asset and go to the Inspector panel.
