| self | The GameObject whose name you want to ensure is unique. |
You can use this method after parenting one GameObject to another to ensure the child GameObject has a unique name compared to its siblings in the hierarchy.
If the GameObject already has a unique name compared to its siblings, its name will remain unchanged. If the GameObject has the same name as one of its siblings, Unity will rename it to a unique name by using an incremental number after the GameObject’s current name. This is useful when trying to avoid duplicate naming.
