Tilemap.BoxFill

public method BoxFill(position: Vector3Int, tile: Tilemaps.TileBase, startX: int, startY: int, endX: int, endY: int): void;

public void BoxFill(Vector3Int position, Tilemaps.TileBase tile, int startX, int startY, int endX, int endY);

Parameters

position	Position of the Tile on the Tilemap.
tile	Tile to place.
startX	The minimum X coordinate limit to fill to.
startY	The minimum Y coordinate limit to fill to.
endX	The maximum X coordinate limit to fill to.
endY	The maximum Y coordinate limit to fill to.

Does a box fill with the given tile on the tile map. Starts from given coordinates and fills the limits from start to end (inclusive).

If the limits are larger than the tilemap bounds, the limits will be capped to the tilemap bounds.
