How to get 1 child instead of multiple in a :GetChildren() loop??
basically, i made a generic loop that finds int values, and if their Value is 0 then it does things.
How can I only do things for only 1 of them? child[number] returns an error that says number is not a valid member of child.
FindFirstChildOfClass() also doesn't work because I need to find one with a specific value of 0.
help pls
part of the script:
1 | for i,c in pairs (some directory:GetChildren()) do |
2 | if c:IsA("IntValue") then |
3 | if c.Value==0 then |
4 | -- idk what to do now |
5 | end |
6 | end |
7 | end |

Try this:
01 | function getNumber(tbl) |
02 | for i,v in pairs(tbl) do |
03 | if v==0 then |
04 | return i,v |
05 | end |
06 | end |
07 | return nil |
08 | end |
09 |
10 | --[[The getNumber function will use a generic for loop to go through all the values of **tbl**, and will return the key and value of a value if it's 0. The function will end when any value in **tbl** is 0, or when the for loop goes through all values in the table. If there are no values found that are equal to 0, the function will return nil |

For what you want, you could set tbl to the values of the IntValues:
1 | local tbl = {} |
2 | for _,v in pairs(something:GetChildren()) do |
3 | if v:IsA('IntValue') then |
4 | tbl[#tbl+1] = v.Value |
5 | end |
6 | end |

I fixed it, just check the script. The reason why is because in the for loop line, I put an underscore as the key, and for the return on line 4 it has 'return i,v', and 'i' wasn't the key. But I fixed it spr_ead 47 — 6y

You could just have a Boolean and only do stuff if it is false and once it does stuff to the first value it gets set to true like so:
01 | Local boolCheck = false |
02 | for i,c in pairs (some directory:GetChildren()) do |
03 | If boolCheck == false then -- continue searching if it hasn't found a zero yet |
04 | if c:IsA("IntValue") then |
05 | if c.Value==0 then |
06 | BoolCheck = true -- change to false to stop iterating |
07 | end |
08 | end |
09 | end |
10 | end |
