Title: energy no longer transmitted in build craft electrical pipes

Version: 1_0_3

OS: redhat linux RHEL6.4 64bit and windows 7 64bit

Java Version: windows 7 64bit with 1.7.0_07-b10

Description of Problem:

I built 4 sterling engines to power my grinders and furnances, this worked fine for an hour or so, then the they ovens and furnaces stopped receiving power. It appears that the stirling and steam engines are not transmitting power, yet they are over-heating.

The server is linux RHEL6 64bit with java,

[root@nas01 tekkit]# java -version

java version "1.7.0_21"

Java SE Runtime Environment (build 1.7.0_21-b11)

Java HotSpot 64-Bit Server VM (build 23.21-b01, mixed mode)

[root@nas01 tekkit]#

tekkit is v1.0.6

Error Messages:

none

Error Log:

none

Think ive found the issue, its when using stone conducting pipes, changing them to gold conductive and they work fine, yet there is no large cyan bar inside the pipe to indicate its at a maximum, the power simply stops. This I think is a bug.

[Barranda]

I've got kind of the same problem.

I'm using a magmatic engine>wooden conductive pipe>golden conductive pipe>redstone energy cell. This works fine for about 30 minutes but then the pipes stop sending power and the engines overheat.

The only solution I've found so far is to replace ALL pipes and it will work again.

So yeah, this does seem to be a bug.

[KyneSilverhide]

I think I have the same problem. Here are some screenshots showing my very simlilar setup.

I've got four engines. I can see the "pumping" animation, they output 1MJ.. but they store all the energy and start to overheat.

[Elijah of Thunder Forge]

Same problem here. Initially set up with 3 Thermal Expansion steam engines, and they worked fine until i logged off for a couple hours.

Now both the steam engines and 3 stirling engines just sit there and store energy.

i have replaced all the pipe and moved the engines about and replaced the quarry.

Also have quit and restarted multiple times.

side notes: the stirling engines do not react to any of the wrenches?!?!

if i remove the engines and put them back in immediately they will not line up with the Wooden Con' pipes.

But if i remove the WC pipe and place it again followed by the stirling engine it lines up. found that odd.

Playing single player

Win 7, 64 bit

16 gigs of ram

edit: also, when i start up my world and pull the switches off of the above stirling engines.

i cant shift+click the levers back onto the engines!?!

To re-enact what i did: axe the engines, replace the engines, leave the chunk for the adjacent chunk, remember that that i need to replace the levers, go back to the chunk,

try and shift+click the levers on the engines. doesn't work?!?

hi yes matches my symptoms....I replaced the stone conductive pipes with gold after it stopped working but then about 30mins later that stopped as well.

[Elijah of Thunder Forge]

OK did some more tinkering and i believe i have isolated the problem.

Place your engine setup, doesn't matter what engines.

Place your Conductive pipe, doesn't matter how much or what kind.

Get your setup running across however many chunks you like. doesn't matter.

The Whole setup will run until you quit to menu.

I'm playing single player so i hit single play and load my world.

Nothing is running.

Pickup the engines and replace them.

They refuse to mate up to the wooden conductive pipe. Wrench does not help.

Replace Wooden pipe and then place engine. That Works.

Still no power running through the Conductive pipes.

Replace allllllll of your pipe. Not just one or 99 pieces. ALL of it.

Power is now coursing like it should until you quit the game again...

Pretty sure that the pipes are the culprit, but i still find it weird that i have to also pickup

and replace my stirling engines to put a lever on them....

Edit: This Happens if you only replace the pipe near the appliance...

PROBLEM IDENTIFIED!!!

i think... XD

So take all those pipes u have that aren't working and dump a bucket of water on them!!!!

They start running again!

i think the pipes aren't updating/checking/ticking/whatever... like they should.

Edit: Sadly i have to make sure the water gets near allllll the pipes before they will work...

But at least i don't have to replace anything.

I'm afraid to say that this doesn't work at all for either the conductive pipes or conduits on my server.

I am having the same issue on my multiplayer server. I've had issues with the Stone and Gold conductive pipes but not the wooden ones. When I replace the non-wooden conductive pipes it seems to remember how to work. Have yet to try the running water thick, but I know replacing them works. The issue may be caused somewhere in the chunk load/unload process. I could be wrong but this might be an issue with the technicpack fork code from tekkit version 1.0.5 to 1.0.6. I didn't have this issue pre-update (but granted I didn't have advanced wooden pipes either).

[spxza]

Confirmed from my side. To help, I've noticed this behaviour when a chunk is reloaded. I've replicated it multiple times, and I have to replace all pipes in the chunks that were uploaded.

Workaround is to use a chunk loader, build within the same chunks a quarry keeps loaded, or a world anchor.

[MDGeuy]

Thanks spxza. I have had no luck with the flowing water update trick but will try a world anchor to see it that helps (it should if we are correct). I have also noticed that forcing a pipe-block update fixes it. In the process of replacing my pipes I replaced the "naked" pipe sections and then had to go up a level to continue. When I got upstairs and tore off the glass covers I had on the rest of the pipes (thus forcing an update of the pipe blocks themselves), everything went back to being A-OK.

Update: [[[ FIX ]]] I have confirmed in multiplayer v1.0.6 that using a dimensional anchor to keep chunks loaded prevents pipes from breaking. Broken conductive pipes-> place dimensional anchor to cover chunks in question-> remove and replace conductive pipes.

100% thanks go to spxza on this.

Any chance that this is what is being described: https://github.com/BuildCraft/BuildCraft/issues/630

Although, that ticket is around golden conductive pipes only, the behavior is similar. 1.0.6 ships with BuildCraft 3.5.0. Further related tickets:

https://github.com/BuildCraft/BuildCraft/issues/844

https://github.com/BuildCraft/BuildCraft/issues/829

https://github.com/BuildCraft/BuildCraft/issues/717

I am going to upgrade BuildCraft to 3.5.3 (I don't have the energy to test 3.5.1 and 3.5.2) and will report.

[spxza]

Ok, this is a tricksy one. The Tekkit BuildCraft repo is at https://github.com/CannibalVox/BuildCraft and is a fork of the main BuildCraft repo at https://github.com/BuildCraft/BuildCraft. Is someone up to the task of merging the fixes for the above issues and testing? Changeset is https://github.com/BuildCraft/BuildCraft/commit/f578aa0e2ca4af50750d04792646bc4c27cdd3c6, and consists of an additional 3 lines. Looks like it fixes things.

[spxza]

I've applied the above mentioned patch and it works. I added the affected classes into the existing BuildCraft jar, as I am too lazy to get the version numbers right.

Here's the JAR: https://docs.google.com/file/d/0B1wZpKM8RMxTejJ4SU5sWFNiYlE/edit?usp=sharing

If you don't trust me, the 3 affected classes:

https://docs.google.com/file/d/0B1wZpKM8RMxTWnJJYTZ5eG4tUG8/edit?usp=sharing

https://docs.google.com/file/d/0B1wZpKM8RMxTVkVEX3lncEp0LVU/edit?usp=sharing

https://docs.google.com/file/d/0B1wZpKM8RMxTY3VMZnRRSWxidmc/edit?usp=sharing

Put this classes into BuildCraft-1.5.1-3.5.0.Tekkit.jar in buildcraft/transport/

There are a few other patches that may fix blocker bugs. If these affect me, I'll clone CannibalVox's BuildCraft repo, apply them, and issue pull requests.

[spxza]

I issued a pull request to CannivalVox's repo. Please can someone test. Luckily, no client-side fixes required (at least for SMP), but same jar is usable for SSP.

Hi spxza, My conductive pipes are full functional again, thank you.
