I'm having problems with entity.neighbours parameter.
In documentation it says this:
When called on a pipe-connectable entity, this is an array of entity arrays of all entities a given fluidbox is connected to.
As I understand it it looks like this:
E = entity
p = parameter
|E1|E2|E3|....
|p1|p1|p1|
|p2|p2|p2|
.
.
.
But when I try to count how many neighbours does that middle pipe have, it says its 1.
I count it like this:
Code: Select all
function tableLength(anyTable)
local count = 0
for _ in pairs(anyTable) do count = count + 1 end
return count
end
Edit: Or is there and array for every entity type?

For fluidboxes the result is an array of array of entities.
Because 1 entity can have multiple fluidboxes of which each can be connected to multiple entities.

Thanks for the reply, but I think I do not undestand.
An entity can have multiple fluidboxes, thats obvious,
but how can 1 fluidbox connect to more entities?

The storage tank is 1 fluidbox but has 4 different in/outs. The standard pipe is 1 fluidbox but has 4 different in/outs.
A "fluid box" is the thing that holds the actual fluid. The little connection symbol you see with alt-info enabled is the connections to that 1 fluidbox.

Oooh... I thought fluidbox is a pipe connection
Sorry and thanks.

Hello.
I have a question about this same subject.
There is a mod, Subterrain_modified. Its main feature is long underground conveyors and pipes. Moreover, during construction, the distance between the entrance and the exit is calculated, and the necessary number of conveyor belts or pipes, depending on the distance, is taken from the player's inventory. And when dismantling - returns.
With conveyors, everything is fine, but with pipes ...
In Factorio 0.15 this script worked
Code: Select all
--actions for subterrain pipes on built
function subterrainPipesOnBuilt(event)
if settings.global["underground-pipe-cost-multiplier"].value <= 0 then return nil end --no pipe cost
local entity = event.created_entity
local player = game.players[event.player_index]
entity.rotatable = false --Prevent rotation, as that can be used to game the system
local otherPipe = entity.neighbours[2] or nil
if not otherPipe then
return nil --no need to do anything if this is the first placed
end
local distance = getDistance(entity, otherPipe)
local calc = (math.floor(distance * settings.global["underground-pipe-cost-multiplier"].value))
otherPipe.force = "player"
if checkCount(player, calc, "pipe") then
entity.destroy()
player.print("You don't have enough pipes in your inventory to create this length.")
player.print("You need " .. checkCount(player, calc, "pipe") .. " more. ")
restoreDeniedItem(player, sp)
else
player.remove_item{name = "pipe", count = calc} --charge the player the pipes
end
end
And in 0.16 it does not work anymore.
How to make it work?
Thank you.
P. S. Sorry, it is Google Translate.

I found the solution to the problem.
Just a table with coordinates placed in another table.
The solution looks like this:
Code: Select all
local otherPipe = entity.neighbours[1][1] or nil
Thanks to all!

For the future when you are not sure whats in property I recommend this:
Code: Select all
log(serpent.block(interesting_thing))
It's really useful for debugging too - especially of raw data on data stage.

That returns {} when printing entity.neighbours[1] in this case...

or without comment
Code: Select all
my_text = serpent.block(my_table, {comment = false})
