[Mod Request] Re-generating water source.

[bgsmithjr]

If you dig a 1x1x1 hole and put a water source in it, then scoop it out the water is gone. If I was to make a kitchen sink, it would only be good for one bucket of water.

[LorenzoVulcan]

Do you mean to regenerate infinite water in a 1 x 1 x 1 hole like in minecraft?

[LolManKuba]

Time to make an infinite water source.
You need 1 bucket of water. (or two if you don't want to make a trip back)
An ocean/lake.
And now you need to dig 3 combined holes. Poor the water into both width ends.
It should look like this

[bgsmithjr]

On dev-01222012 I could scoop water_source. and once it was scooped the water would disappear. On what version does your idea work?

EDIT: On dev-03182012, you can scoop water that is not water_source.

AND: Yes, I was referring to the idea you mentioned. I did not know it was in minecraft.

[SAMIAMNOT]

...On dev-03182012, you can scoop water that is not water_source...

Is that true cuz I cant do it now. I have the latest version.

You need to take the water source that is in the middle. It is the one that will regenerate between the other two sources. If you take one of the end ones, it can't regenerate.

The only difference between Minetest water and the Game of Life is that water doesn't get smothered by having too many neighbors (well, and that other node types serve as holes/barriers).

[SAMIAMNOT]

Oh I see.

I made renewable wter source in a pool on accident and wanted to know how it happened so I cpuld do it again. Basically you have to let water from one water source flow into another water source? Is that it?

Any node that is air or flowing water becomes a water source if it has two or more water source neighbors. Diagonals do not count (guess that's another difference from Life).

Actually, diagonals do count. If you have a hole that is 2x2, and place one water source in opposing corners, the other two corners will become water sources not flowing water.

Here is the sample of what I mean.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

     XO
     OX

becomes (where X is the water source.)

     XX
     XX

That is correct :)

Diagonals don't count because you have to consider the situation relative to one of those Os (potential spaces to be changed to a water source). If diagonals counted, the following pattern would work as well:

Code: Select all

XO
XO


(It doesn't.)

[SAMIAMNOT]

Okay thanks. There was nothing about this online, so I thought renewable water source could only be created by the mapgen. I suppose in oceans the only reason the source is renewable is because there are other sources next to it?

[twoelk]

indeed this:
XOX

is the same as this:
OX
X

both have two directly neighbouring water sources.
That is why this:

XXXXXXXXXXXXXXXXXXXXX
XOOOOOOOOOOOO

will eventually turn the complete bottom row to sources.
That is how you fill lakes easily and pretty fast.
Make one row by going like

XOXOXOXOXOX

where if the row is thus
123456789
place source on 1 and 3 and wait
place generated 2 at 5 and wait
place generated 4 at 7 and so on ....

and then add at one side something like

XXXXXXXXXXXXXXXXXX
O
X
O
X
O
X

working along both sides works faster and safer

of course you may have to adjust youre strategy to the shape of your lake but this should also give an idea of which water sources can be safely scooped up and replenish and which not as they would not regenerate.
Keep in mind this may need some time for the server to do and on laggy servers you may have to wait for quite a while for the transformation to take place.
Using this knowledge you can build interesting stone generators.

[SAMIAMNOT]

What are StoneGenerators ?

[rubenwardy]

Placing lava next to water to create unlimited stone.

[SAMIAMNOT]

I thought that made obsidian.

[LionsDen]

Only if flowing water or water sources are touching on edge or corners does it turn lava sources into obsidian. If water sources or flowing water touch flowing lava on the edges or corners, it turns the flowing lava into stone.

[SAMIAMNOT]

I tested this and none of this worked with lava sources. I tried the "XOXO" thing and no luck.

Correct. They, "fixed," that a release or two ago. Water sources yes; lava sources no. Something about the rarity of obsidian, or doing it like Minecraft, or whatever.

[SAMIAMNOT]

ARGHH!!!!

[rubenwardy]

There was quite an outburst at the time: viewtopic.php?id=5145

(please don't bump that topic)

[SAMIAMNOT]

Dont worry; I wont.
So did they mod it so you can have infinite lava.
