## About

# Autotiling & Edge Transitions

## Overview

Hard edges between grass and water look like a checkerboard. Autotiling picks the correct edge/corner transition tile based on a bitmask of neighbors. This skill defines the transition set and the bitmask rule.

## When to Use

- Two terrain types meet and the seam looks harsh.
- You want maps to look hand-blended without hand-placing every edge.
- You need a repeatable rule for which transition tile to use.

## Process

1. Define the base terrains and their priority order (e.g. water tile lookup for performance.

```text
bitmask = N*1 + E*2 + S*4 + W*8  ->  transitionTile[bitmask]
```

## Rationalizations (Stop Lying to Yourself)

| Excuse | Reality |
|---|---|
| "I will hand-place edge tiles" | Hundreds of edges by hand is unmaintainable. Use a bitmask rule. |
| "One generic edge tile is enough" | Corners need their own tiles or you get gaps. Author the full set. |

## Red Flags - STOP if you catch yourself:

- Hard checkerboard seams between terrains.
- Missing corner transition tiles.
- Bitmask computed but never cached (slow).

## Verification

You are NOT done until every box is checked:

- [ ] A complete transition set exists per terrain pair.
- [ ] All bitmask cases render correctly on a test map.
- [ ] The bitmask->tile lookup is cached.
