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

Parameters

positionPosition of the Tile on the Tilemap.
tile Tile to place.
startXThe minimum X coordinate limit to fill to.
startYThe minimum Y coordinate limit to fill to.
endXThe maximum X coordinate limit to fill to.
endYThe maximum Y coordinate limit to fill to.

Description

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.
