Unity 2D Tilemap

Author and script tile-based 2D levels in Unity 6.3 LTS with the Grid/Tilemap system, the Tile
Palette, colliders, and runtime painting. Targets Unity 6.3 LTS (6000.3).

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.
