How to find all children that have an attribute set to a specific value?

How would I go about getting all children who have a specific attribute set to a specific value? For example, I created a boolean attribute, and only want to reference the children that have that value set to true. Any ideas on how to do this, preferably with GetChildren() and GetAttribute()?

Like this?

function GetChildrenWithAttribute(Object, AttributeName, AttributeValue)
    assert(typeof(Object) == "Instance", "Argument 1 is not an Instance!") -- Optional thing, this is just to check if the Object is an Instance and to Error if it isnt
    
    local tab = {} -- Table so we can store our Instances
    for index,item in Object:GetChildren() do -- Iterates through provided object
        if item:GetAttribute(AttributeName) == AttributeValue then -- if there is a Attribute with a specific value
            table.insert(tab, item) -- Adds Instance to table
        end
    end

    return tab -- returns the Table with Instances
end

local Array = GetChildrenWithAttribute(example, "Active", true)

Yeah thats basically the way I have I was just looking if there was a simpler way to do it with just getchildren and getattribute and no loops

You could, but that would more so overcomplicate things, and would be more complicate just to check every single value, if would be a lot easier to check using a loop, looking through all the values inside a table.

You might consider using CollectionService instead of Attributes, though you might need to do some minor restructuring if you make that change. Collections are designed in a way that you can loop through everything in a collection using something like GetTagged

Instead of object:SetAttribute(attr_name, value) or whatever it is, you’d use CollectionService::AddTag(object, tag_name)
