From my experience its safe. But as with any mod for any game, USER BEWARE. Things can always go wrong so expect that there is a non zero chance of save corruption. But anyone who uses mods for any game should know to keep multiple saves and not just keep saving overtop of your more recent one. Be smart and the rare chance of corruption wont matter

so I've been watching this for a while and I think it looks quite interesting. I also have a suggestion; The player should be required to place something like power poles to keep areas from collapsing back in.
PC is best.

Yes, this in something I intend to implement, I just have more important stuff to do first (like making the automated digging work correctly for instance :D)

but yes it will be there, and I think I have an idea on how to implement that

I also will try to implement special lights and power poles that can only be built underground and that are attached to the roof, making it have no colision with the ground (can walk under, drive under, build under, etc.)
it is not my priority thoughfirst things first as they say !

well, indeed, it is probably safe to use, but in the developping process, I had a few times where I could not load the game because it said there was an error, I should have removed all of thoses, but I might have missed one or two.
so ... yeah, have fun but be careful: keep a backup just in case I missed something somewhere

I'll fix it and upload a new version (I have a few changes to make first though, so the upload will probably not be until tomorrow)
well, I think it won't be for today eather, got caught up in refactoring some code ...
since this is only a graphical bug, I think you won't mind having to wait a bit ? (that way I can do more than just a bugfix release)

First off, I want to say that this mod has a lot of potential and I look forward to seeing where you go with it.

Second, I had some trouble with the independent item elevators as well, and decided to look into the code to see if I could figure out what was going on.

It looks like there are some sign errors in the elevator placement for the east-west elevators.

Code: Select all

			if string.find(_entity.name, "upperside") then
				if _entity.direction == defines.direction.north then
					input_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x - 0.5, y = _entity.position.y + 0.5}, force=_entity.force}
					output_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x + 0.5, y = _entity.position.y - 0.5}, force=_entity.force}
				elseif _entity.direction == defines.direction.east then
					input_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x + 0.5, y = _entity.position.y + 0.5}, force=_entity.force}
					output_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x - 0.5, y = _entity.position.y - 0.5}, force=_entity.force}
				elseif _entity.direction == defines.direction.south then
					input_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x + 0.5, y = _entity.position.y - 0.5}, force=_entity.force}
					output_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x - 0.5, y = _entity.position.y + 0.5}, force=_entity.force}
				elseif _entity.direction == defines.direction.west then
					input_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x - 0.5, y = _entity.position.y - 0.5}, force=_entity.force}
					output_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x + 0.5, y = _entity.position.y + 0.5}, force=_entity.force}
				end
			else -- if string.find(_entity.name, "lowerside")
				if _entity.direction == defines.direction.north then
					output_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x - 0.5, y = _entity.position.y - 0.5}, force=_entity.force}
					input_item_elevator = _entity.surface.create_entity{name = "fast-transport-belt", position = {x = _entity.position.x + 0.5, y = _entity.position.y + 0.5}, force=_entity.force}

				end
			end
additionally, I noticed the following lines of code in move_items:

Code: Select all

					local item_to_move = {name = "", count = 1}
					for name, count in pairs(lane_input.get_contents()) do
						item_to_move.name = name
						break
					end
while this works, you could replace it with

Code: Select all

					local item_to_move = {name = next(lane_input.get_contents()), count = 1}
and it does the same thing, but with a little less overhead.

ok, the part for the move item is indeed better, at the time I codded this, I had no idea of the next() function...

the part where I build the elevator items, I will double check to understand how I could get it wrong
I think that once I make the change, I'll upload a new version !

Hi, we have been noticing that your mod has a high readout on script update compared to all other mods we're using. Had a bit of a dig and it turns out you have a lot of functions running every tick, other mod authors have got things running less often using timers. Saw what you did with the digging robot center but the item elevators seem to cause a bit of lag, we were also having desync errors earlier that we couldn't pinpoint. Might be unrelated, but thought it would be necessary to inform you.

We are getting a desync error in multiplayer whenever items get stuck in the independent item elevators, as well as when they get stuck in the item elevators that come with the surface drill. Isolated the issue from earlier, I think it has something to do with the move_items function.

Basically, the coordinates for the input and output belts got swapped around for the elevators facing east/west. I tested it by using inserters to load items onto (what should be) the output belts. Then I made the changes to elevator placement and placed new elevators and the new ones worked right.

There's an issue with the fluid elevator;
I made some changes and found

Code: Select all

base_level = -1,
and incorrect positions for pipe_connections at fault.
Also, there are jarring graphical inaccuracies with the subsurface ground textures and the fluid elevator texture.

Thanks for the awesome mod!

Edit: The passive air vents actually moves pollution to the subsurface instead of moving it out.
The powered active vents do as advertised though.

well, the base_level = -1 is not an error, it just make you have to use a pump to output from it
the fact that the pipes are not alligned with the graphics is known and is warned on the main post

as to the passive air vent, what it does is slowly set the polution to the same ammount on the surface and subsurface
so if the pollution level on the surface is higher than on the subsurface, it is to be expected to have the pollution move down to the subsurface

can you make a vent that takes pollution down a level? or is that too cheaty

do you want it just to get rid of the pollution to some surface you'll never go to ? or is there a real reason (and of so, which is it?)
If the answer is yes to the first, then I won't. if you can provide me with a good reason to have that, I'll think about it!

After seeing the discussion on this in the Modding Help thread you made, I had a go at fixing it. Here's a version of control.lua that might fix the desync. (I couldn't test it in multiplayer, but I did do a basic sanity check in single player - started a new game, dug a hole, went below - so I think I at least didn't break anything.)

control.lua
Maybe better?

Yeah tried removing the global onTick stuff since we shouldn't be using global variables to store method information - see post in-context (viewtopic.php?f=25&t=24171&p=152497#p152362)

Even after that it still seems to desync, I'm suspecting it's something stupidly simple. If you want I can supply the whole control.lua, just be prepared I've had to modify quite a lot to reduce the lag in our multiplayer. (gone from having script update over 4ms to just under 1ms with the changes I've done, digging robots don't cause lag anymore, etc.) Hope not to step on anyones toes.

The algorithm for the digging robots really needs help, the further away the tile is the longer it takes for the robot to be deployed. It's not only that it takes longer for it to be deployed, it also doesn't deploy robots if the tile is 20 or so tiles away meaning that you have to rip up the digging robot center and move it every now and then.

Yes, I know, I'm working on it, this is the reason why it is not available when you start a game (unless you switch it on)

plus, if the walls are 20 + tiles away, it stil works, it is just painfully slow (and the game goes dosnwn to ~10 UPS when you're lucky)

Below are some of the various changes I have made to increase efficiency, we have this working with 8+ digging robots in multiplayer with less than 1ms script update and 59-60fps/ups, I have also introduced a limit since it becomes more and more work the farther away from the center you search with this algorithm, it is far from perfect but it is better. Anything not pasted below remains unchanged from your version, all ontick functions have been surrounded with the appropriate associative_table_count check similaraly to digging_robots_manager(event). Air vent prototypes were changed to reflect changes done since they really do not need to be checked every tick, more like once every five ticks.

Re: [WIP][0.12.22+] Subsurfaces 0.0.4 : build beneath your base

Logistic and Construction robots delving into subsurface and going back into surface would be nice.. but it would be a pain to code that i think.. Just a suggestion :)

This is a bad idea. Rather than an optimization, this is an anti-optimization.

Code: Select all

if associative_table_count(t) ~= 0 then
    for k, v in pairs(t) do
        --do some stuff
    end
end
has strictly worse performance than just

Code: Select all

for k, v in pairs(t) do
    --do some stuff
end
this is because the associative_table_count version is equivalent to

Code: Select all

function waste_some_time (t)
    local time_to_waste = 0
    for k, v in pairs(t) do
        time_to_waste = time_to_waste + 1
    end
    return time_to_waste ~= 0
end

if waste_some_time(t) then
    for k, v in pairs(t) do
        --do some stuff
    end
end
Note how if the table is empty, you're doing the same loop setup and termination check in either case, but have added the overhead of a function call, a variable assignment, and a comparison. On the other hand, if the table isn't empty, you've added the overhead of a function call, a comparison, and an additional complete loop through the entire table (with variable assignments at each step). And by doing all this extra work, you've gained... absolutely nothing in return.

TL;DR: only use associative_table_count if you absolutely need to know how many things are in the table. If you just need to check if it's empty, replace

Code: Select all

if associative_table_count(t) ~= 0 then
with

Code: Select all

if next(t) then
or

Code: Select all

if associative_table_count(t) == 0 then
with

Code: Select all

if not next(t) then
or ask yourself if checking for emptiness is even necessary in this case (for the use case in question, it's probably better to just let the loop terminate because there are no elements to loop through than to throw in a separate emptiness check).
