I have this script which requires an iv loop or collection service but I dont know which is better
CollectionService
is not used to get a table of children. It's used to add tags to objects and get objects with a tag. If you're trying to simply get the children of an object then use a General For Loop. If you're trying to get objects with a specifc tag use CollectionService
If my answer solved your problem please don't forget to accept it.
