Variable AUTOMAP_EMPTY`Const`

AUTOMAP_EMPTY: -1

The wildcard: an input cell holding it constrains nothing, an output cell holding it leaves the target alone.

Deliberately the same value as two-d/render's own EMPTY, declared here rather than imported so this module needs no renderer. tests/automap.test.ts asserts the two stay equal, the same way the version test pins version.ts to package.json.

Example

import { automap, AUTOMAP_EMPTY, type AutomapTarget, type AutomapRule } from '@datamoc/mw_games/rpg';

declare const map: AutomapTarget; // a real two-d/render.TileMap satisfies this structurally

const cornerRule: AutomapRule = {
  width: 2, height: 2,
  input: { ground: [1, AUTOMAP_EMPTY, AUTOMAP_EMPTY, AUTOMAP_EMPTY] },
  outputs: [{ ground: [2, AUTOMAP_EMPTY, AUTOMAP_EMPTY, AUTOMAP_EMPTY] }],
};

const changed = automap(map, [cornerRule]); // how many cells the rules actually wrote
