Unity Levels & TileMap 🧸 ¶

A tilemap is a grid in which each cell is an image called a tile. It's a common way to create 2D Levels. They can be Rectangular or Isometric. TileMaps can be created using external tools such as Tiled.

From the editor, you can:

• Create a Palette
• Create Tile Layers (ex: Ground, Props, etc.)
• Place the tiles on the tilemap

Creating Layers allows us to superpose tiles. In Unity, we create a Grid, and each tilemap is a layer.

📚 See also: the property Order in Layer.

A terrain is a game object used to create large outdoor realistic landscapes. It's used in 3D Levels.

Terrains:

• Terrain settings: you may change material to legacy diffuse
• Terrain Texture: add both the texture and its normal map. Target strength and opacity to put textures one above another
• increase height (shift decrease) => soften
• 5th icon is a tree, 6th is a leaf+leaf group?

Lighting

• auto generate: disable if level goes darker
• render Mode => auto/important/not pixel/vertex
• shader
• lightning => Environment => source: color
• cast shadow (mesh rendered) off for walls (wall is not casting shadows on the player)
• shadow type: hard => projected on the wall
• light with the sun transparent (mesh)
