- Sponge mod for Minetest
|
|
- water removal for survival
|
|
|
|
made by Benjie/Fiftysix - 27/8/18
|
|
|
|
soggy sponges can be found quite rare, deep in the sea where it is dark
|
|
these can be cooked into dry sponges, and then placed near a liquid to remove an area of it
|
|
they will hold the water away until they are removed.
|
|
to use them again, they have to be cooked.
|
|
|
|
sponges create a 9x9 area of air-like nodes that water can't flow through (checks for protection)
|
|
if sponges have cleared more than 3 nodes of liquid, they become soggy sponges
|
|
removing a sponge or soggy sponge will turn a 9x9 area of air-like nodes back into air
|
|
(air-like nodes can be removed in protection by removing a sponge outside the protection, they are not meant to be permanent)
