To get all Children within an Instance, you would use Instance:GetChildren(), This will return an array (a table) of Instances.

local Children = Part:GetChildren() -- Gets Children
print(Children) -- returns table

A More Powerful one being Instance:GetDescendants() which gets the Instances Children and their Childrens:

local Children = Part:GetDescendants() -- Gets All Children
print(Children) -- returns table of Everything Descending from an Instance

However you would use a for loop to iterate over all the Instances within that List, going through it manually would suck

for index, Instance in pairs(Part:GetChildren()) do -- Iterates through a List of Items
    print(index, Instance) -- prints number, and Item
    Instance.Transparency = 1 -- Changes Properties of Instances
end

However, you would need to type check if the Instance is what you want:

if Instance:IsA("BasePart") then -- Checks if the Instance is a Part

If the loop iterates through an Item that doesn’t have the Property, it will error.

great, we get the children, now how do we affect the properties of all the gathered children?

edit: i sent this right as you edited your message

You can get the children of a part one by one by for-looping through them:

local Part = --part you want to get the children from

for index, child in pairs(Part:GetChildren()) do
    child.Transparency = 0 --change any property of the child
end

or what @DasKairo suggested:

local Part = --part you want to get the children from
local Children = Part:GetChildren() -- Gets Children
print(Children) -- returns table

The first option would be shorter and simpler in my opinion.

it works, but errors when it tries to change the color of the script, so i tried applying this script:

if Instance:IsA("BasePart") then -- Checks if the Instance is a Part

from @DasKairo but that gives another error:

without that code:

Could you show the full script?

#8

with or without @DasKairo’s code?

#9

All of the code will be required to debug it

#10

Just send me the script you have right now.

#11

That’s what I meant by this, your code should look like this (if you did this):

for index, Instance in pairs(Part:GetChildren()) do -- Iterates through a List of Items
    print(index, Instance) -- prints number, and Item
    if Instance:IsA("BasePart") then
        Instance.Transparency = 1
    end
end

i deleted her code after it errored

it runs into the script and tries to change its color, but ofcourse that isnt a property, heres the diagram of all the children

#13

can i remove the “print(index, instance)” part?

#14

Add a check to see if it is a basepart

#15

Yes, its just a debug

#16

Already said it…

#17

I know. I’m telling him to add it again because there is no way “child” is a table.

#18

i found this to work with no problems, but i tested this on a low-level scale, and it might not be able to get the children of models as well (remember, it was a low-level scale, and i still need to implement this into the actual game)

#19

just tested it, it does not change everything inside a model, only specifically parts

#21

model just has 2 parts inside of it
