IsA (Function)

IsA( String classname ) Returns Boolean Description: Returns true if instance is that class or a subclass

IsA is useful for figuring out if an object is a specific type of object. For example, if you do Part:IsA("Part") it will return "true". Also, you can use structural classes, or classes that cannot be created through Instance.new(string classname). For example, you can do Part:IsA("BasePart").

Example

This can be used to find an object related to a part in a list of objects.

children = script.Parent:GetChildren()

for i=1, #children do
    if children[i]:IsA("BasePart") then
        print(children[i].Name .. " is a Part object.")
    end
end
