Function buildTilemapBody

buildTilemapBody(grid: TilemapGrid, options: TilemapOptions): Body
Build a single physics Body from a 2D tile grid.

Each merged rectangle becomes a Polygon shape on the body. Tiles are laid out with (0, 0) at the top-left of tile (0, 0), so the body's position (defaults to origin) is the world-space location of that top-left corner.

Defaults to BodyType.STATIC and merge: "greedy", matching the most common gamedev use case (level collision geometry from a Tiled / LDtk map).
Parameters
- grid: TilemapGrid
  2D row-major tile grid.
- options: TilemapOptions
  Tile size + body / shape options.
Returns Body
A Body containing one Polygon shape per merged rectangle. The returned body is not yet attached to a Space — set body.space to insert it.
Example
```
const grid = [
  [1, 1, 1, 0, 1, 1, 1],
  [0, 0, 0, 0, 0, 0, 0],
  [1, 1, 1, 1, 1, 1, 1],
];
const body = buildTilemapBody(grid, { tileSize: 32, position: Vec2.get(0, 100) });
body.space = space;
```
