Can you sort string values by alphabetical order?
Is it possible to sort string values by their name?
1 | local stationName = routeFolder.Stations:GetChildren() |
2 | for i = 1, #stationName do |
3 | --in here is a script that basically generates a timetable from the children of the Stations folder |
4 | end |
The reason I can't use the values in any order is because on the return journey the stations list needs to be read in reverse order (from 7 to 1) meaning I would need a way of sorting them by reverse alphabetical order too. I know you can sort tables but is there something similar I could use to sort this? Thanks!

If you are only using numbers as station names you can convert the name into a number and then just compare greater and less to determine the order.
01 | local Stations = {} -- Define table to insert stations into. |
02 | for i,v in pairs(workspace.Stations:GetChildren()) do -- Change "workspace.Stations" to wherever your stations are. |
03 | table.insert(Stations,tonumber(v.Name)) -- Convert the station name into a number, and add it to the Stations table. |
04 | end |
05 | table.sort(Stations, function(a,b) -- Function to sort the table. |
06 | return a<b -- If a is less than b, then put a below b. If you want to reverse the order change a<b to a>b |
07 | end) |
08 |
09 | for i,v in pairs(Stations) do -- Iterate through the stations table |
10 | print(v) -- Print the stations in order. |
11 | end |
12 |
13 | --[[ |
14 | Basic Rundown: |
15 | This code creates a table, adds all of the stations into the table, and then sorts the table from least to greatest (or if you change to A>B, then from greatest to least) |
16 | You can then iterate through the Stations table to do what you need to do. |

The problem is that the station names aren't numbers - the string value names are numbers but the actual values in them are strings. kieranhendy 28 — 4y

Ah I wasnt sure, I went based on your heirarchy in the picture you provided. According to that you named all the stations 1-7, which can be turned into numbers via tonumber. Another thing you could do if they are named "RedStation, "BlueStation", etc is add them all to a table when the game loads and use that tables index numbers to modify it from there.

If you create a table at the start that doesnt change, and is in the order they are supposed to be in, you can just always use that table to create a new, organized table. WizyTheNinja 834 — 4y
