Question Nullable types for NetworkList/NetworkVariable

So I have a struct with string field inside. Because of this I get a compile error:

Code (CSharp):

1. The type 'MyStruct' must be valid unmanaged type (simple numeric, 'bool', 'char', 'void', enumeration type or struct with all fields of unmanaged types at any level of  nesting) in order to use it as a type argument for 'T' parameter

As you know NetworkList and NetworkVariable is generic types, so I can't use nullable types here (in my case it's a string)
Also nullable types unavailable for NetworkVariable.
Is it possible to use nullable types for this two classes somehow?
P.S. Looks like FixedString64 is the way to go, but my IDE doesn't see this struct so I can't implement this in code. I tried using Unity.Collections, but it has not worked.
P.S.2 I just forgot about assembly definition. Added Unity.Collections into it and now everything works!

 

With Netcode 1.0.0-pre8 FixedString64Bytes ceased to work too.
It now raises a runtime error:

Exception: Type Unity.Collections.FixedString64Bytes is not serializable - it must implement either INetworkSerializable or ISerializeByMemcpy

So at the moment we cannot use NetworkVariable<string> neither NetworkVariable<FixedString64Bytes>

Send help.

 

This is a problem for me as well, in case it's missed here I raised an issue on GitHub.

 

Yup, this broke my game as well.
Im now trying to wrap my FixedString*Byte inside ForceNetworkSerializeByMemcpy<T>.

Code (CSharp):

1. struct MyObject
2. {
3.     public ForceNetworkSerializeByMemcpy<FixedString64Bytes> RandomString;
4. }

I'll let you know how it goes.

 

Did this end up working? I'm not a fan of how some information is hidden on git now. Unity is starting to feel more and more like an open source product.

 

Using ForceNetworkSerializeByMemcpy<FixedString64Bytes> is currently the way to go starting from this release. We're looking at bringing back the old behaviour which allowed for just using fixed string on its own.
