So today, at 11:30 pacific, I'll be streaming a test world with Finite Flowing Water (Realistic Fluids Overhaul) and RotaryCraft.

The goal: See if I can get RoC pumps to drive a Hydro engine when the water does NOT follow normal minecraft physics.

Hey Guys,

I need your Help pls or yours Reika

I have the Issue that if i place High Pressure Turbine parts no matter which ones the Game sometimes crashes

Here is the Crash Report:

Railcraft hidden block?

With Rotarycraft/Dragon API/etc on the client, and not on the server, I get error messages during play. Easiest way to trigger is from drinking a potion.

So I'm having a "fun" time trying to get RotaryCraft and Realistic Fluids Overhaul to work together. RFO gives finite, flowing liquid.

Problem the first: A simple DC engine, hooked up to a pump and some pipes, ending at a liquid spiller, generates infinite water. More than one bucket is output for every bucket that is input.

Problem 2: As far as I can tell, a DC engine can put unlimited pressure (And hence volume of water) into a piping system. There's nothing "reasonable" like "a DC engine can build pressure up to X, a steam engine can generate more pressure up to Y, etc" -- and I find myself thinking that I should be able to turn water pressure into power somehow. That's analogous to an industrial coil being charged up by a weak engine.

Problem 3: The liquid spiller wants to find a place to put the water blocks. It runs into stack overflow.

When I was near the ground, it would find a place to put the water. But even though I had a pit underneath the spiller (that the pump was pumping out from), the spiller was putting the water *Everywhere*. At least 10 blocks horizontal distance, maybe more.

Since I was trying to see if I could run hydros with this, I made a holding "tank" way up in the air. This was just a floating dirt box, basically. I put a spiller at the end of the pipe, and ... Got the stack overflow.

I moved the spiller to the underside of the last pipe, rather than the end of the last pipe, and it worked fine. With the same "overflowing" effect, it completely filled the holding box. So, the next thing to do: open the bottom, so that the water can flow down next to the hydro paddles.

Well, as soon as I did, the spiller stopped working. It had a holding box beneath it, that box just had a hole in the bottom. One of those hindsight "the spiller is looking for the lowest possible place", and not putting a limit on it's searching.

===

For a world with finite water, the water multiplication of a DC engine, a pipe, and a spiller is excessive. (RFO currently has rainfall refilling of oceans, rivers, and swamps, so it's not strictly finite). And for a world with flowing water (RFO is one of two mods that I know of that give finite flowing water; the other simply moves source blocks down to the place where the water stops flowing to), searching for the lowest point to place water isn't necessary.

What I cannot figure out is that I kept getting water blocks in the air. Not moving, not doing anything, just sitting there.

I'm not sure how they got placed in the air if the liquid spiller wants to find something solid to spill against (Q: Will it place against other water blocks? In particular, if the surface of a small pond is solid block 8, meta-data 1 (slightly drained) instead of block 9, will it attempt to place anything there?)

===

Lastly: I had trouble with the hydro's. The book only says that they rotate CCW, but that doesn't actually specify which way -- face the other way, and CCW becomes CW.

Equally, I was expecting that a bedrock upgraded hydro would not consume lubricant, just like a bedrock shaft Gear. That it does came as a surprise as well.

(edit: Thank you for pointing out my oppsie :-)

DragonAPI makes changes to the base game. It must be on both sides or neither.

[p]GalacticCraft integration perhaps? (I don't play GC, but if I see planets in a minecraft thread ...)[/p]
[p]As for the placement of the hydros: I've replaced and rotated the hydros; I no longer know what their original facing was.[/p]
[p]If I remember correctly, I started with the output shaft on land, placed some shafts, then placed the hydros at the end of the shafts (over the drainage tub -- can't start there because it's air).[/p]
[p]The infinite water is a problem, because it means the drainage tub will overflow, and the hydros won't turn.[/p]
[p](I was wondering, at first, if a DC engine would actually pump water fast enough to keep the hydros at full speed, a pure violation of thermodynamics. I was not expecting to get the drainage problem that I got.)[/p]
[p]EDIT:

[/p] [p]What I cannot figure out is that I kept getting water blocks in the air. Not moving, not doing anything, just sitting there.

[/p]Turned out to be some strange client-side caching error. Log out, log back in, they are gone.[/p]
[p]Going far enough out that the chunks should unload, and reload, did NOT clear them out.[/p]

Woahh what is that? Is it a new mod? Your own game? Tell us please! I beg of you

I wish.

Aha. The pipes/pump do have a limit.

My pump is full. The pipe next to it is 653.588 kPa. No more water is being pumped out, so no more water is being pushed through the liquid spiller, and no more water is "demanded" by the pipes.

So it's not infinite. There is a certain number of buckets in that first pipe block, and it won't go higher.

===

Meanwhile, am I doing something wrong? With just a DC engine, I got a time per operation of 1.95 seconds (39 ticks). With one steam engine, 0.95 seconds (19 ticks). With 4 steam engines, the same 0.95 seconds. I expected it to go down to 0.45 or 0.5.

Ahh ... did not think of that. The book does not say.

But if that's the case, then a gear should make it faster.

Meanwhile: One pipe block holds 29 full blocks, plus a little leftover. Tested with water. That's a far cry from infinite, and actually less than a reservoir.

===

EDIT: Steam engines, if placed while you are looking at the water pipes, will face away from the water pipes, connect to them, and face their output red square at you.

But: If you are on the water pipe, and facing where you want them to go (the machine placed first), they will face the wrong way. Using the screwdriver to turn them around will result in them facing away from the water pipe, and not getting a connection.

===

Hydros: Putting them down fresh actually had them in the same orientation, but scooped out the water blocks next to them! Apparently, I have them too low/close to the water hole.

I tried liquid pipes. Not bedrock pipes. Will try those tomorrow.

This is general RoC knowledge. Almost all machines work faster if supplied with more Speed, even if total shaft Power remains the same.

I admit to only now starting play in survival-style, instead of creative-style, play and testing.

(Yea, creative coil, and not worry about any details. Now, I'm seeing what DC and Steam engines can actually do. Answer: Make noise :-).

===

Is there any way to let adjacent engines "share" the wool muffling effect, or check more than distance 1? My first attempt at steam engines had them adjacent, with the whole thing completely surrounded by wool -- thick enough to stop any fire from the underground flames.

Still made noise.

Spacing the engines out, so that I could put wool between them? Worked -- now each engine had the three wool blocks.

(I was surprised to find that the DC engine was happy to count a wool block under it. I was annoyed when I realized that the steam engines had three sides used for water, fire, and output, forcing a single-style build for the foursome.)

I know, but the question is, what can you do with RoC, not with another mod that modifies RoC.

Put wool on top and below.
