Unity 2D Tilemap

Author and script tile-based 2D levels in Unity 6 with the Grid/Tilemap system, the Tile Palette, colliders, and runtime painting. Targets Unity 6 (6000.0 LTS).

Package note: the core Tilemap (Grid, Tilemap, Tile, TilemapCollider2D) is built in. Rule Tiles, Animated Tiles, and Tile Palette brushes live in the separate "2D Tilemap Extras" package (com.unity.2d.tilemap.extras) — install it via Package Manager before using RuleTile.

When to use

• Use when laying out a 2D level by painting tiles, setting up a Grid + Tilemap, adding collision to the map, using auto-tiling Rule Tiles, or generating/editing tiles from script.
• Use when scenes contain a Grid with Tilemap children, or *.asset tile/palette files.

When not to use: level design practice (pacing, blockout, layout principles) → level-design. 3D tile/grid placement → Unity's own 3D tooling (ProBuilder / grid brushes; no dedicated skill here). The platformer character that moves over the tiles → platformer / unity-physics.
