Problem with Layer

Unity Engine
1

I follow a tutorial on youtube to create your multiplayer games and then for some time there is this error that appears I do not know where the problem comes from.

Link video:

the error in question:

A game object can only be in one layer. The layer needs to be in the range [0…31]

using Mirror;

    [SerializeField]

It would be useful to include the error, we can’t see it from here :slight_smile:

Looks like a Unity error, not netcode related.
Check out the Unity manual on layers :slight_smile:
