Question Does the valid entity change its index and version during runtime?

I'm trying to store some references of entities, after instantiating them inside a list in a monobehaviour script, and for safety i'm wondering in what cases can the index and version of the valid entity change during the runtime?

 

It’s an identifier. If the entity remains valid, the identifier remains valid and doesn’t change (why would it?)

 

To add on top of the enswer, index and version are only allocated, when new entity is created. Not during its life span.
Released indexes can be recycled and reused, from destroyed entities.
Version will always increment, when using recycled index.
So in any normal circumstances, there is no way to having entities identifier conflict of index+version.

 

Thank you very much
