[MOD 0.12.x] Equalizer chests v1.4.0

Post by Boogieman14 » Fri Nov 07, 2014 11:52 am

*NOTE* Version for Factorio 0.13 and up can be found in the mod portal!


So I made my first mod :)



This mod will provide 48-slot chests that will 'connect' with their direct neighbours and balance ("equalize") the contents of these chests (think Communicating vessels). My personal use case for this will be with train unloaders, where the chests furthest from the middle of the wagon don't receive nearly as much materials as the center chest.

This mod only deals with itemcounts, so no effort is made to balance individual items. There's also a lower threshold of 10 items below which no items will be transfer (this to avoid ping-ponging stuff back and forth).

I haven't tested it extensively yet, but some basic testing showed no obvious problems. I think it should be MP-safe.

As of 0.11.2, the scripting now also works when the chest was placed by a robot.

Of course, I welcome any tips and suggestions for improvement :)

You're welcome to include this mod in any modpacks, provided you include a link to this forum post whenever you publish the pack.

Updated for 0.12.0
The update for 0.12.0 has only been tested briefly, no extensive playthroughs have been done with it yet (but all the basic functionality appears to work: placing, balacing, removing, destroying). I have not tested this at all in MP and no provisions have been made yet for different forces.

Sounds useful, but for barely more than that one specific purpose that you mentioned. But for that purpose, it could be quite invaluble.

Yeah, that's probably true for many specific mods like this. I'm pretty sure I'll enjoy the benefits though, and if nothing else, it's been a nice learning experience :)

Hey Boogieman14,

I was very exited to see this!

This sounds a lot like the mod I suggested/requested here: https://forums.factorio.com/forum/vie ... =33&t=6251

I'm not sure why you're "equalize" the content over the different chests, all that's needed is that two adjacent chests become one container.

I'm glad for this though and will definitely give it a try.

I didn't use this yet but checked source and is this ok?:

Code: Select all

--game.onevent(defines.events.onpreplayermineditem, removedEntity)
--game.onevent(defines.events.onrobotpremined, removedEntity)
--game.onevent(defines.events.onentitydied, removedEntity)
You don't seem to check for removed chests atm.

I suspect your "all that's needed" may actually be a lot more complicated than it sounds :) Especially when you want the flexibility you're describing of being able to add (and presumably removed) containers at will. This mod will leave each container as a standalone unit that interfaces with its neighbours. So it doesn't become one big inventory.

Yes, that's actually ok :) I guess i might as well remove that bit, because it isn't needed. Removal makes the entity invalid (entity.valid = false), all the code that interacts with chests checks for that valid flag, and in the tick-loop, if the entity is invalid, it gets removed at that moment. As far as I can think of, nothing else is needed for removal.

Looks nice. I downloaded the mod to see how you where handling the detection of new chests (and ticking of the chests) only to read the first two lines of the control.lua file and get a giant grin across my face :D

I don't see any issues with the logic you've got setup - nice mod :)

Right... I got to that part of code later... :) I guess I no longer need to create my tiny mod with long&narrow boxes anymore :P

Let's come up with a possible scenario:
I have line setup of 10 chests.
I only input to 8 of them.
Only pull from 4 of them.

Let's say that after inputting some items, I stop doing so, and items are only being pulled out of 4 chests at random. What would happen in that case?

Test it and let me know ;)

You'd probably end up with 4 empty chests (well, that one's for sure) and 6 chests with a number of items in it. The exact numbers depend on the distribution of the extraction inserters. If they're all at one end of the line, the other chests will contain between 1 and 60 items. If they're evenly distributed, the leftovers will all be in the 1-10 range, I think.

Bug report; if you put blueprints in they will be cleared.

Would it be to much to ask for Equalizing Passive Provider Chest? 8-)

Thanks for the useful mod :D

Seems to work well. Any chance of seeing future logistic versions of these chests?

That's interesting. Blueprints probably have some special properties that the code doesn't take into account. I'll have to look into it, although not sure I'll spend too much time trying to fix this as it seems such a fringe case :)

That should be possible, although not sure if/when I'll get around to it as I've been taking a break from Factorio (so much to do, so little time :lol: )

Glad you like it :)

Thanks for this mod. I find it invaluable at train stations. I got sick of accidentally making these chests instead of regular steel chests though, so I tinted some steel chests with a blue-ish tint:

Awesome, I never got around to doing that myself, even though I ran into the problem myself a few times in my latest game :oops: I've added it to the first post, thanks :)

I use your chest as a buffer at my Iron and Copper smelting stations.
I haul in great volumes of ore and store them in the chests.

The ore goes in tat the top as fast as I can get it. (Normally the belts are full, I just had an alien attack take down my power)

Hey Boogieman14,

I thought of an upgrade to your chests. Quantum Chests!
They will work like underground belts. You build them in pairs and they stay connected, but can span a distance underground. The distance can be increased by upgrading, like underground belts.

Cool layout, hadn't thought of using them like that ;)

As for the quantum chests, I seem to remember I've seen something like that already. Or maybe those were remote inserters or something like that. I probably won't make something like that, as I feel this kind of "teleportation" doesn't really fit in the setting of the game. Equalizer chests work by physically handing stuff over to adjecent chests.
