The BreakFromPrefab method is used to detach a GameObject from its prefab. This means that the GameObject will no longer be linked to the prefab it was cloned from, allowing for independent modifications without affecting the original prefab or other instances of it.
Call this method on a GameObject instance that was created from a prefab when you want to make changes to the instance that should not be reflected in the prefab or other instances of the prefab.
// Assume 'gameObject' is an instance of GameObject cloned from a prefab
if (gameObject.IsPrefabInstance)
{
gameObject.BreakFromPrefab();
// Now you can modify 'gameObject' independently of its prefab
}
