Question about 'in ipairs'..

[Feche1320]

What does 'in ipairs' or 'in pairs' do on a loop and what other use it could have?

Thanks

ipirs() is an iterator function that only work for tables indexed by numbers starting from 1, it also sort the indexes while looping thru them, but it will not work if a index skip a number, for exemple:

local table = { [2]="b", [3]="b",[1] = "a" } 

"for" will loop thru all 3 cells

local table = { ,[2]="b", [4]="b",[1] = "a" } 

"for" will stop on 2 cell

if you want to loop tabels indexed by eny data type (including elements) you should use "pairs()"

in expresion

for key, var in (i)pairs(sometable) do 

key will contain the index

var will contain the value of the cell
