> Extra tools and commands to extend WorldEdit for Minetest
## Current commands:
### `//floodfill [<replace_node> [<radius>]]`
Floods all connected nodes of the same type starting at _pos1_ with <replace_node> (which defaults to `water_source`), in a sphere with a radius of <radius> (which defaults to 50).
```
//floodfill
//floodfill water_source 50
//floodfill glass 25
```
### `//overlay <node_name>`
Places <replace_node> in the last contiguous air space encountered above the first non-air node. In other words, overlays all top-most nodes in the specified area with <replace_node>.
Will also work in caves, as it scans columns of nodes from top to bottom, skipping every non-air node until it finds one - and only then will it start searching for a node to place the target node on top of.
Note that all-air columns are skipped - so if you experience issues with it not overlaying correctly, try `//expand down 1` to add an extra node's space to your defined region.
