[Solved] Number Range in a Table?

I've created a table for a level system

local Levels = {

    --XP is the data we are comparing
    [0] = {1,0,10},
    [10] = {2,10,20},
    [20] = {3,20,30},
    [30] = {4,30,40},
    [40] = {5,40,50},
    [50] = {6,50,60},
    [60] = {7,60,70},
    [70] = {8,70,80},
    [80] = {9,80,90},
    [90] = {10,90,100},
    [100] = {11,100,110},
    [110] = {12,110,120},
    [120] = {13,120,130},
    [130] = {14,130,140}

}

return Levels

The problem is that when comparing a value that is not in the table, for example 8, it gives a error, what I want to do is to create a range. Example:

local Levels = {

[NumberRange.new ( 0, 10 )] = {1,0,10}, 

--I don't know if NumberRange is compatible with tables but I want to do something similar

So that if the value is 0,1,2,3,4,5,6,7,8,9 or 10, it should return {1,0,10} And the same with the others values.

Can someone tell me a way to do that?

Tell me if you want me to send you the other scripts wich depends on this module script . Thanks in advance

Tables can be indexed by anything. For an explanation of why, see here.

So a fairly intuitive way to do what you're looking for is to just do a linear search through the ranges.

function findLevelData(xp)
    for key, value in pairs(levels) do
        if (key.minimum <= xp) and (key.maximum > xp) then
            return value
        end
    end
    -- We failed to find it
    return false
end

One thing to watch for is that you take care with overlapping ranges. For example, if you have the ranges 0-10 and 10-20, you want to make sure that an XP value is only ever considered a member of one of the ranges.

Thanks a lot dude!, this is really useful! jesxd444 38 — 5y

Also, It works with the key=0 and then it gives the following error ServerScriptService.LevelSystem.LevelSystemAPI:18: attempt to index local 'key' (a number value) jesxd444 38 — 5y

Which one is line 18 in your script? fredfishy 833 — 5y

Is line 3 in your script jesxd444 38 — 5y

Are you doing the ranges, or the [0], [10] thing for indexes? fredfishy 833 — 5y

I'm using [0],[10],... jesxd444 38 — 5y

Mine was written assuming the NumberRange.new thing. fredfishy 833 — 5y

Ok, thank you so much! jesxd444 38 — 5y
