## What it is
A collection of reusable C# scripts from Unity Technologies that extend the 2D Tilemap system with custom tiles and brushes, such as Rule Tiles, Animated Tiles, and various painting brushes. Development has moved to the official Tilemap Extras package in Unity's Package Manager, and this GitHub repository is now read-only.

## Use cases
- create autotiling rule-based tiles in unity
- add animated tiles to a 2d tilemap
- custom tilemap brushes for unity level design
- isometric and hexagonal rule tiles
- paint gameobjects onto a unity tilemap
- randomize tiles while painting a 2d map

## When to choose
- you are on an older Unity version that cannot use the Tilemap Extras package
- you want to fork or customize tile/brush scripts beyond what the official package offers
- you need to study Unity's reference implementations of custom Tilemap tiles and brushes

## When to avoid
- you are on Unity 2021 or later and just need the features - install the Tilemap Extras package from the Package Manager instead
- you need bug fixes or new features - the repository is read-only and no longer developed
- you need support via GitHub issues - issues must go through Unity's official channels
