Description

When using a NetworkList with no NetworkManager in scene (in my solo mode), operations on the list (add, insert, remove, clear...) throws an NullReferenceException.
This is because of the use of m_NetworkBehaviour that hasn't been initialized.

NetworkVariable<T> doesn't suffer from this behaviour because a check on m_NetworkBehaviour is made.

Actual Outcome

A null reference exception is thrown an the operation is not done.

Expected Outcome

The operation is done.

Environment

  • OS: Windows 11
  • Unity Version: 2021.3.22f1

Bump!
I don't understand why it takes so long for this simple bug I reported and provided a solution. My PR is now waiting for 4 months...

Do you really prefere throwing a NullRefException (breaking code flow, so potentially other things) instead of doing the operation and showing the warning you wrote specially for this case?

@NoelStephensUnity
Hi,
