On [Collection factory manual](https://defold.com/manuals/collection-factory/) it says

A prefix `/collection[N]/`, where `[N]` is a counter, is added to the id to uniquely identify each instance:

But in my code I saw `/instance[N]` instead.

Correct me if I’m wrong.

You’re mixing it up. Example collection factory IDs:

```lua

{ --[[0x10ecdbf90]]
  hash: [/container] = hash: [/collection1/container],
  hash: [/double_target_holder] = hash: [/collection1/double_target_holder],
  hash: [/double_target_1] = hash: [/collection1/double_target_1],
  hash: [/double_target_2] = hash: [/collection1/double_target_2]
}

```

it is from factory.create() not from collectionfactory.create()
