Floodfill

The floodfill tool fills a chosen area with the provided amount of blocks to place. The Active Block is the block used to fill an area.

By default the tool fills an area by equally spreading across and down from the selected starting position. The amount of blocks used can be set using the Limit Slider in the Tool Options, and a visualisation of the floodfill is shown when hovering over the Main View Window.

The Up option is a toggle that makes the tool only fill blocks that are located above and on the same layer as the cursor.

The Down option is a toggle that makes the tool only fill blocks that are located below and on the same layers as the cursor.

The Horizontal option is a toggle that allows the tool to spread across the area to be filled.

The Corners option is a toggle that requires 'Horizontal' to be enabled. It will allow the tool to extend the area to be filled by including corner blocks, which results in a boxier shape.

Using right-click will initiate a floodfill at the position of your cursor.
