Renewable resources (Stranger Things with the River Water)

[Punk]

I think I found a bug in river water. River water is not renewable, right?

With 2 buckets I can create infinite.

Oh, I can post only 3 images.

Where I find a list of all no renewable resources?

PS: minetest 0.4.16

That is intended. Further information about the reason why can be found in the PR's description.
List of non-renewable liquids in minetest_game: Search in this file for " liquid_renewable = false ".

Currently matching these criteria:
default:lava_source
default:lava_flowing
default:river_water_source
default:river_water_flowing

I talk about the possibility of filling as many buckets as you want with river water.
If river water is not renewable, I understand that it should be scarce.

[Punk]

The Minetest Wiki don't have a page about all renewable and no renewable resources or Category:Renewable.

List of basic no renewable resources (generated):

Coal ore
Iron ore
Gravel
Lava
Clay
Copper ore
Mese ore
Mese block
Diamond ore
Ice
Desert Cobblestone
Tin Ore
River Water (?)
Coral
Coral Skeleton
Waterlily
All Dirt (except dirt with snow [???])
Ignore*
Cloud*

And of course, all derivatives

The river water source node is not technically renewable, if it was the sloping rivers would flood over the banks and make a massive mess of the world.
However, when you use a bucket on a river water source node it should not leave a hole in the river, so i added code to the bucket mod that replaces the river water source node when you use a bucket. So it then becomes infinite in another way.

Hum, I get now. So, river water isn't renewable because bucket is not renewable, right?

[paramat]

No, 'renewable' is a parameter of the node itself, that decides if 2 sources can create a 3rd.

All right, thank you!

Here's a list of (hopefully) all renewable items in Minetest Game:

I'm surprised to learn that there is actually a way to create infinite river water, although not in the traditional sense. Thanks, paramat. I have update its wiki page accordingly.

Good job! But, as I had said, the bucket isn't renewable, so river water isn't too after all. Neither in this strange way.

[paramat]

The bucket is irrelevant, all water sources are infinite, buckets or buckets of water are not. You can get infinite water sources using 1 bucket and emptying it everytime.

[Wuzzy]

Paramat: Congratulations, you managed to surprise me a second time, in the same thread! This is a very rare achievement, and you should be proud. :-D

Here, take this mese block:

But still, I don't get it. How can you get infinite water sources if all you got is only 1 water bucket (or 1 water source)? o_O
All I can do with a single water soure is destroy it, or take and place it with a bucket. But I can't multiply it.
I think you need at least 2 water sources for infinite water, because then you can do the diagonal placement trick like shown in the wiki.

So, paramat: What am I missing?

PS: Can the thread starter please rename this thread? It's obviously NOT a bug. :P

[paramat]

As i wrote, you can get infinite water sources, just not infinite buckets of water.
But yes, even with river water you need at least 2 source nodes for the taken source to 'force regenerate'.
