finite liquid

[proller]

all liquids with constant volume and/or intresting effects like caves flood, bubbles, ...
its disabled by default and configurable for speed-realism
new config variables:

# Constant volume liquids

module to make springs (infinity sources) (too destructive when placing above sea level!) https://gist.github.com/proller/4987328

So cool. Well done for this.

[PilzAdam]

Bugs:

• The lowest level of water stays forever in its place
• Whole oceans turn into flowing nodes if water is taken from them
• There are tons of graphical glitches in oceans
• The performance isnt eally good

Suggestions:

• Remove the lowest level of water when next to air
• If a liquid with the highest level is next to one with the highest level -1 turn both into sources
• Use the source block texture if liquids with the same height are next to each other
• Update more frequent and in slower steps to get better animations
• Maybe keep infinte sources and only handle flowing nodes with the new system.

[PilzAdam]

It should be also saved per-world so old maps arent broken.

There are tons of graphical glitches in oceans

most of them is air bubbles, other - bug? in mapgen - layers of air under water, but all of them disappear over time

The performance isnt eally good

now only 2000 cycles every second, should be better

Maybe keep infinte sources and only handle flowing nodes with the new system.

its posiible via water_source param2 == 128 (last bit) -> infinity source

It should be also saved per-world so old maps arent broken.

now its fully compatible with old transformLiquids , and now saving per-world is no sense

[proller]

Remove the lowest level of water when next to air

bad idea -
steps: levels and air
321A
32AA
311A
22AA
21AA
2AAA
11AA
1AAA
AAAA

and there is no water

[proller]

i think it almost ready to merge.
big bugs fixed -> speed now better.
by default it disabled, to enable write in config:
water_finite = true
water_update = 0.2

number of levels not changed - it fully compatible with old saves, and new saves with old code.

After last changes it seems to not work anymore.
All liquids are infinite, settings in config doesnt change anything.
Moreover digging in water gave me a few water source and flowing water nodes.

[proller]

its optimization like PilzAdam suggestion.
now i make it adjustable, few minutes of test and i will commit..

[RealBadAngel]

if you added to it infinite sources again then whole idea is fucked up and theres no point mergin it.
I just carved a huge cave under a small lake and water level havent changed even by 1 milimeter.

reducing new under ocean bubbles: https://github.com/celeron55/minetest/pull/466

[MirceaKitsune]

I didn't test this yet or understand exactly what it does. But from what I can tell, it's a very good idea! I can think of many ways it can go wrong however. If it does work, then please do add!

[Uberi]

Are infinite sources still possible with finite liquids enabled in survival mode?

[proller]

now you can place water_source with last bit=1 like param2 = 128
and block will be infinite.
in any mode

[Uberi]

I might have misunderstood, but how would one obtain such a water block in survival mode legitimately (i.e., without /give or /giveme)

[proller]

now only with lua mod or core mod
