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:
for i,c in pairs (some directory:GetChildren()) do
if c:IsA("IntValue") then
if c.Value==0 then
-- idk what to do now
end
end
end

Try this:
function getNumber(tbl)
for i,v in pairs(tbl) do
if v==0 then
return i,v
end
end
return nil
end
--[[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
--]]
--Usage
local Table = {
1,
2,
0,
3,
4
}
local k,v = getNumber(Table)
print(k,v) -- Will print 3,0, because a 0 has been found in the 3rd key of the table, and 0 is its value. If the 3rd key was 5, the function will return nil, nil.
For what you want, you could set tbl to the values of the IntValues:
local tbl = {}
for _,v in pairs(something:GetChildren()) do
if v:IsA('IntValue') then
tbl[#tbl+1] = v.Value
end
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:
Local boolCheck = false
for i,c in pairs (some directory:GetChildren()) do
If boolCheck == false then -- continue searching if it hasn't found a zero yet
if c:IsA("IntValue") then
if c.Value==0 then
BoolCheck = true -- change to false to stop iterating
end
end
end
end
