How to Find all Children of an Instance by Class?
We do have :FindFirstChildOfClass() but It will only choose one... If I'm wrong please tell me. I want to know if there is a way to find all children from one class.

That I'm aware of, there is no built-in function to do it. The best way to get all children by a class is writing a function for it yourself, which is fairly simple!
Loop through the instance's children, check their class, if it matches the one you are looking for, then add it to a table. In the end, return the table.
It's fairly simple to write
01 | local function getChildrenOfClass(instance, class) |
02 | -- table to hold the children |
03 | local children = {} |
04 |
05 | -- looping through the instance's children |
06 | for i,v in pairs(instance:GetChildren()) do |
07 |
08 | -- check if the child's class matches the one we're looking for |
09 | if(v.ClassName == class)) then |
10 | -- we add it to the table |
11 | table.insert(children, v) |
12 | end |
13 | end |
14 |
15 | -- we return the table, so that it can be used when calling the function |
16 | return children |
17 | end |
Afterwards, you can call your function whenever needed, and access it!
To access it, you can do it in the same way that you would for FindFirstChildOfClass() !
1 | -- This will allow you to use the children you've selected using the function |
2 | local childrenOfClass = getChildrenOfClass(model, "Part") |
3 |
4 | for i,v in pairs(childrenOfClass) do |
5 | print(v.Name) -- This would output the part's name, you can do anything else with it! |
6 | end |

for the "local childrenOfClass = getChildrenOfClass(model, "Part")" when is say model, "Part" do w have to change it? If so, what should we change it to. NathanTheCraziest 105 — 5y

Model is your Instance, but I wanted to give a practical example. "Part" is the class type, could be anything. Script, MeshPart, ShirtGraphic, anything you would like! Norbunny 555 — 5y

Wait, how do you make it create a clone of the stuff that it finds and put in a player? NathanTheCraziest 105 — 5y

Using :Clone() and parenting the cloned instance to the player; https://developer.roblox.com/en-us/api-reference/function/Instance/Clone Norbunny 555 — 5y

Do note that IsA will return true for any object that inherits that Class too Filipalla 504 — 5y

1 | function GetChildrenOfClass(Instance, Class) |
2 | local ChildrenOfClass = {} |
3 | for _, Child in pairs(Instance:GetChildren()) do -- iterate through table returned by GetChildren |
4 | if Child.ClassName == Class then -- Check if ClassName matches Class Argument |
5 | table.insert(ChildrenOfClass, Child) -- insert into table |
6 | end |
7 | end |
8 | return ChildrenOfClass -- Return the table |
9 | end |
