[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.
