How to find Table

#1

local trainSpawnsAndLines = {["9"] = {"Ostheim"}}

I think i can find “Ostheim” with if table.find(trainSpawnsAndLines, tostring(stationName)) but how can i find the Number? if table.find(trainSpawnsAndLines, tostring(stationName)[tostring(selectedLine)]) then but that dont works.

Edit: Would this work?:

if trainSpawnsAndLines[stationName][selectedLine] then

table.find does not work on dictionaries. Documentations say it works on array-like tables. Just check directly if trainSpawnsAndLines[stationName] ~= nil and then you’re good from there.

Assume and let trainSpawnsAndLines be a table that contains an arbitrary amount of numbers as strings:

{"2", "5", "9", "474"}

As you can see, it is array-like. To access the number, simply go for:
table.find(trainSpawnsAndLines[stationName], selectedLine)

That gives me a Error

#4

Why don’t you just do 'local Stations = {

[9] = ‘Ostheim’,
}’

Then do table .find(Stations,‘Ostheim’)
that should return the table index where ‘Ostheim’ is in so 9

#5

How could i print the 9 then

#6

Do it as a variable so where the table.find is make it
local TableIndex = table.find(Stations,‘Ostheim’)

Print(TableIndex)

#7 
local trainSpawnsAndLines = {["9"] = "Ostheim"}

local trainSpawnsAndLinesVariable = table.find(trainSpawnsAndLines, tostring(stationName))

if trainSpawnsAndLinesVariable then

Didnt worked

You can try adding the station name as a key and keep a set of lines as the value:

local trainSpawnsAndLines = {
    ["Ostheim"] = {
        ["9"] = true
    }
}

you can then check for a certain station with a certain line by doing this:

local trainLines = trainSpawnsAndLines[tostring(stationName)]

if trainLines and trainLines[tostring(selectedLine)] then
    print("found line")
end

You can add another line to the station by writing in something like ["#"] = true,

Edit: if you know ahead of time that the station name will always be a string, you can just omit the tostring call for the trainLines statement.

local trainLines = trainSpawnsAndLines[stationName]

You can do a similar thing for selectedLine if you know it will always be a string.

But you dont have the Line added in your script

#16

Which line are you talking about

#17

What do you mean here? table.find() returns the index (number) of the object.

table.find(trainSpawnsAndLines, "Ostheim") -- returns the index
#18

I need to check if 9 Exist and if Ostheim is inside 9

#19

Then put 9 stops before that maybe?

Also dont worked
