POV Posted February 26, 2015 Report Share Posted February 26, 2015 Hi MCPublic folks, I've done a few searches to see if this has shown up, but couldn't find anything, but then again, I'm a first time poster, so uh, be gentle! I've been working on an item sorter based off of this video: https://www.youtube.com/watch?v=NHjWYCDYJ4s . The sorter appears to work on the Creative server (1.7.x) and also appears to work in stock 1.8 standalone servers. When the sorter is built on PvE it appears that the redstone logic breaks and the sorter basically misses many items. I've rebuilt the sorter a bunch of times, and get different, but still broken results. After talking with Vintre he believes it might be the following bug in Spigot: https://hub.spigotmc.org/jira/browse/SPIGOT-546 I'm not sure what the implications are to the rest of the server with the options recommended there, but Vintre and I would appreciate it if the Admins could take a look and see if this is possible. I believe without this fix all sorters based off of comparators and hoppers will be unreliable and unpredictable. I believe the behaviour changes when the block with the sorter is unloaded and reloaded. I have an example at -242, 71, -1001. Thanks for any input on this!

Pyr0mrcow Posted February 27, 2015 Report Share Posted February 27, 2015 Tested our item sorter design on the Yowie planning server after it was updated to 1.8, and it did the same thing; splitting flow seems correct, though I hadn't thought of that possibility until this post came up...I thought it was just lag causing weird movement.If this can be even mostly fixed with just a config, that'd be wonderful.

POV Posted February 27, 2015 Author Report Share Posted February 27, 2015 Yeah, from what I've read the path objects take when going through a sorter shouldn't have changed when going 1.7 -> 1.8, so it does seem like an honest bug in spigot. I'm going to setup a small spigot server at home and see if I can replicate this. Of course the powers that be running Nerd have to take into consideration how this change will affect others, if it will have any adverse affect on CPU or Load etc...

POV Posted February 27, 2015 Author Report Share Posted February 27, 2015 (edited) Sadly it appears the that alt-ticking=true setting mentioned in that Spigot bug thread doesn't work. (I'm testing on a virgin spigot-1.8 install from tonight and in creative mode). I'll play around some more, but for the moment it appears that circuits using Hoppers + Comparators are busted with Spigot. I'm not sure if there are other bugs that can show up without using the comparator, my guess is anything the depends on the direction an object will follow when a hopper has two outputs is going to break.

POV Posted February 27, 2015 Author Report Share Posted February 27, 2015 Okay, and further testing and reading has found me a way to make my local server work, but reading the spigot bug report, the fix might not work everywhere... https://hub.spigotmc.org/jira/browse/SPIGOT-333 The settings I'm using on my own server that make my sorter work are: hopper-alt-ticking: true ticks-per: hopper-transfer: 7 hopper-check: 7 hopper-amount: 1 Quote Link to comment Share on other sites More sharing options...
POV Posted March 4, 2015 Author Report Share Posted March 4, 2015 I know everyone must be busy with fixes/changes after the new rev, and going to 1.8, but is anyone looking at the busted hoppers? Quote Link to comment Share on other sites More sharing options...
POV Posted March 8, 2015 Author Report Share Posted March 8, 2015 Yay! It looks like spigot-1.8.3 fixes the hopper glitches! Is there an ETA or wild-assed guess as to when PvE will update to spigot-1.8.3? Quote Link to comment Share on other sites More sharing options...
CROCKODUCK Posted March 8, 2015 Report Share Posted March 8, 2015 Island of Piraeus built a 35 item sorter and tore it down after we found out when you leave the chunk it unloads all the hopper times into chests and in general does not sort well. This will be far more than just lag fixes and patches. Quote Link to comment Share on other sites More sharing options...
Pyr0mrcow Posted March 8, 2015 Report Share Posted March 8, 2015 Glad you caught it before I hooked a quadrant of Yowie's up... Quote Link to comment Share on other sites More sharing options...
Vintre Posted March 8, 2015 Report Share Posted March 8, 2015 (edited) Island of Piraeus built a 35 item sorter and tore it down after we found out when you leave the chunk it unloads all the hopper times into chests and in general does not sort well. This will be far more than just lag fixes and patches. I have over 200 items sorted in my sorter. And no unloads in the chest so far. But yep this bug make 20% of them to not sort for some reason. Hope that spigot 1.8.3 will fix the issue for good. Edited March 8, 2015 by Vintre Quote Link to comment Share on other sites More sharing options...
Pyr0mrcow Posted March 9, 2015 Report Share Posted March 9, 2015 (edited) Well, there's another one that skips hoppers even when loaded, but rather than going into chests they just go through the line without being sucked in by the filter. Also caused by Spigot. Hoping they do something about that too. Edited March 9, 2015 by Pyr0mrcow Quote Link to comment Share on other sites More sharing options...
POV Posted March 9, 2015 Author Report Share Posted March 9, 2015 (edited) Yeah, what I'm seeing in Spigot before the 1.8.3. release is that items will miss dropping into hoppers below, and other times drop into hoppers that shouldn't be accepting input (due to the redstone signal strength, etc). Basically when I'm building my two stage sorter (the first stage sorts out ores and items to cook), the second stage takes the output of the ovens and the items that bypassed the ovens, and sorts the rest into storage, I end up with a massive mess... Items jamming up the ovens, stuff missing and rolling into the overflow, and other items filling deactivated hoppers. My smaller test (8 item sorter) on a creative server running spigot-1.8.3 shows that the hoppers appear to work correctly. EDIT: Forgot to mention, the hoppers appear to work correctly with either the original bone stock Spigot config.yml or the modifications mentioned earlier in the thread!

BernzSed Posted March 20, 2015 Report Share Posted March 20, 2015 Do we know when or if we can expect the hopper problem to be resolved? Thanks! Quote Link to comment Share on other sites More sharing options...
POV Posted March 22, 2015 Author Report Share Posted March 22, 2015 Do we know when or if we can expect the hopper problem to be resolved? Thanks! I'm guessing this will be addressed next rev then? Or is there still any chance on this one? Quote Link to comment Share on other sites More sharing options...
BernzSed Posted March 23, 2015 Report Share Posted March 23, 2015 I do kind of have a "workaround" in Brom's autosorter, but it results in a crippling FPS drop. I'd share my solution, but we'd probably bring down the server with the lag from all the redstone updates. Hoping to hear from the tech admins about the progress on the issue. Does anyone know what version of Spigot the server is running? Quote Link to comment Share on other sites More sharing options...
Pyr0mrcow Posted April 1, 2015 Report Share Posted April 1, 2015 Could temporarily lock the next hopper in line when an item enters to give the hopper below a brief moment to drain it if applicable. Would slow down the sorter, but it'd work.Really hoping that the Spigot update is implimented, though... Quote Link to comment Share on other sites More sharing options...
BernzSed Posted April 2, 2015 Report Share Posted April 2, 2015 That was actually what I did in Brom; I had a pulsing redstone signal along the top of the hoppers. 3 ticks on, 1 tick off, repeated. It pulsed for several seconds after an item was detected in any number of hoppers throughout the top-level hopper line, ensuring that it would pulse when there were items to sort, and not pulse when not needed. It worked, more or less. but it made the game unplayable for everyone nearby; FPS dropped down to the single digits while the redstone was pulsing. Eventually, I tore that solution down down and tried a different solution based on hopper directions, which only seems to work for a seemingly random one-third-ish of the hoppers. And Brom is still left without a working item farming/transporting/sorting infrastructure this rev. Quote Link to comment Share on other sites More sharing options...
POV Posted April 3, 2015 Author Report Share Posted April 3, 2015 I wonder if there is resistance to changing the version of spigot on the middle of a Rev? Fixing this, might cause other issues, etc. I'll probably come back next rev and see if I can build my redstone monstrosity then. Quote Link to comment Share on other sites More sharing options...
