Creating the buildings with tilemaps gave the artist the flexibility to reshape and resize them more efficiently, and save on texture space since parts of the building use the same texture. Warehouse, House: These tilemaps are used to create the warehouse and house.When the tiles dry, the “wet” tiles are removed. WateredTileLayer: This is used by the game logic to make the tiles look wet.TilledTilemap: These tiles are used in the code to detect tiles where seeds can be planted.ObjectsInTiles: This is used for GameObjects painted in a tilemap with the GameObject Brush from the Tile Palette, like the fences.GroundBase: This is the ground artwork comprising tiles for the paths, grass, mud, and stone to fill the gaps from the elevation tiles.Water: These tiles use a different shader than the others called Sprite-Lit-Material, which is made in Shader Graph to simulate water animation.UnderwaterTiles: These are used for underwater tiles, for the cliff, and as green ground for the pond area.Some of the tilemaps under the Grid GameObject include: A component called Terrain Manager is attached to the Grid GameObject, providing gameplay possibilities that we explain in the following section. This helps keep the number of tilemaps low. An exception is the building tiles used for roofs, where the edges of these tiles are highlighted.Īll of the tiles in the sample are the same size and shape, and contained in the same Grid GameObject. This is why most of the texture of this tile set is black, to avoid reflecting any light created for the rim effect. However, since most of the tiles are used for the ground, they don’t need a rim light. In Happy Harvest, mask maps are used to create rim light silhouette effects for the character and props. The normal map and mask map textures are added to the main texture of the tile set in the Sprite Editor. Read the article “ 2D light and shadow techniques in the Universal Render Pipeline” to learn how lighting was created in the sample. These share the same dimensions and layout, but are painted for displaying the lighting. To disperse these props in a more organic pattern, you can put them in a GameObject in the Hierarchy outside of the tilemap.Įvery tilemap under the Tilemaps folder has counterparts called normal map and mask map textures. However, the GameObject Brush, a feature included in the 2D Tilemap Extras package, is used to place some of those objects, like wooden fences, in a tilemap grid. Generally, props that are vertical and rendered in front of, or behind, the character are separated into GameObjects in another sorting layer. In contrast, the background pine trees, laid out as square-shaped tilemaps, require fewer tiles. These maps require more tiles because they are used to create paths of varying shapes. The tiles in Happy Harvest were created in sections, with priority given to tilemaps that are used extensively in the game, like the main path or grass patches. To get a comprehensive introduction to how the Unity Tilemap system works, download the e-book 2D game art, animation, and lighting for artists. Only create separate tilemaps when needed, like instances where you need distinct depth planes. This might sound convenient from an art creation perspective, but it would be less performant due to the layers of overlapping pixels. The cobblestone path in the sample could have been created with layers of tile artwork: One for the cobblestone and one for the grass. All these tiles are batched at the same time by setting the rendering Mode to Chunk in the Tilemap Renderer. You can see how the tilemap called GroundBase contains all the ground artwork. In Happy Harvest, all the tilemaps live under the Grid GameObject. When authoring tilesheets, it’s important to avoid combining layered tilemaps when they’re not needed, as this helps reduce overdraw. They also come with automatic collision generation for more efficient testing and editing. A brush tool makes it efficient to paint tiles on a grid, and they can be scripted to use painting rules. This is because tiles can be rendered by a dedicated renderer, and the tiles not visible on the screen can be disabled. Tilemaps can help save time on art creation, as well as memory and CPU usage. This is especially useful for games with large walkable areas, like a simulator or RPG. Instead of designing a level as one big image, you can split it into brick-like pieces that are repeated throughout a whole level. The Unity Tilemap system enables you to create a game world using tiles, which are small sprites placed on a grid.
