Struct Replication in UE4

Development Programming & Scripting
1

Hello,

I’m coming from a UDK background and notice there’s no documentation on struct replication in UE4. It appears that structs now follow the same rules as classes where only updated members get sent over the network. Is this actually the case, or do structs always replicate in a single bunch like in UDK?

Thanks in advance.

A coworker has reported that structs replicate just like actors. A single variable can now change in a struct and only that single variable gets replicated. Can I get a confirmation?

I’d also want to know the answer for this question. Could someone from Epic confirm this information?

Structs used to be replicated as a whole object in Unreal Engine 3, but now for UE4 EpicGames say that they have changed this and now Structs replicates only Struct members that have changed.

If you want to make sure that this is really the case, take a look at this thread and test it out by yourself:

Thanks a lot! :]
