2017-10-08 (thetaepsilon)
|
||||
A lot more of the new flow logic work.
|
||||
There are two sub-modes of this now, non-finite and finite mode.
|
||||
Non-finite mode most closely resembles "classic mode", whereas finite mode is more intended for use with mods such as dynamic_liquids which enable water sources to move themselves.
|
||||
Everything that was functional in classic mode more or less works correctly now.
|
||||
Still TODO:
|
||||
+ Flow directionality - things like flow sensors and airtight panels will flow in directions that don't make sense from their visuals.
|
||||
Possible feature requests:
|
||||
+ Making tanks and gratings do something useful.
|
||||
|
||||
|
||||
|
||||
2017-09-27 (thetaepsilon)
|
||||
Start of new flow logic re-implementation.
|
||||
This mode is current *very* incomplete, and requires a per-world setting to enable.
|
||||
Adds a pressure value stored in all pipe node metadata, and a mechanism to balance it out with nearby nodes on ABM trigger.
|
||||
Currently, this inhibits the old behaviour when enabled, and (again WHEN ENABLED) breaks pretty much everything but normal pipes, spigots and pumps.
|
||||
For this reason it is far from being intended as the default for some time to come yet.
|
||||
What *does* work:
|
||||
+ Pumps will try to take in water (and removes it!) as long as internal pressure does not exceed a threshold.
|
||||
- a TODO is to make this pressure threshold configurable.
|
||||
+ Pipes will balance this pressure between themselves, and will slowly average out over time.
|
||||
+ Spigots will try to make the node beneath them a water source if the pressure is great enough and the existing node is flowing water or air.
|
||||
- This is admittedly of fairly limited use with default water mechanics; those looking for more realistic mechanics might want to look at the dynamic_liquid mod, though that mod comes with it's own caveats (most notably drastic changes to previous worlds...).
|
||||
What *does not* work:
|
||||
+ Flow sensors, valves. Valves in particular currently do not function as a barrier to water's path under the experimental logic.
|
||||
- TODO: internal code to allow this to be overriden.
|
||||
|
||||
|
||||
|
||||
*seems this hasn't been updated in a while*
|
||||
|
||||
2013-01-13: Tubes can transport items now! Namely, I added Novatux/Nore's item
|
||||
transport mod as a default part of this mod, to make tubes do something useful!
|
||||
Thanks to Nore and RealBadAngel for the code contributions!

-- Directionality code
|
||||
Currently, only "simple" flowable nodes exist, and they will always equalise pressure with all six neighbours.
|
||||
A more sophisticated behaviour for this would be flowable node registration with some kind of custom callback, such that water can only flow into or out of these nodes in certain directions.
|
||||
This would enable devices such as the airtight panels, sensor tubes and valves to have correct flow behaviour.
|
||||
|
||||
-- (may not be possible) stop removing water nodes that were not placed by outputs when off
|
||||
In non-finite mode, spigots and fountainheads will vanish water sources in their output positions, even if those output nodes did not place them there.
|
||||
This is annoying though not game-breaking in non-finite mode, where water sources can at least be easily replenished.
|
||||
Fixing this would require some kind of metadata marker on water nodes placed by spigots and fountains, such that only water sources placed while the device is "on" are removed when it is "off".
|
||||
It is debateable whether existing water sources should be marked for removal when the device turns on again.
