Network ID vs Handle

Problem

As described in C++ objects refs in Lua caveat, it is crucial to store .networkId or .handle instead of actual object references and later retrieve those objects using ObjectManager.ResolveNetworkId(networkId) or ObjectManager.ResolveHandle(handle).

However, you may wonder what is better and safer to store. There is a difference between these.
Always remember, that .handle can be reused by the game after reconnect, and .networkId is a unique network ID assigned to this object by the server.

Solution

Prefer storing .networkId instead of .handle for all GameObject.
