DECLARE_STRUCT_OPS_TYPE_TRAITS(ReplicatedArrayType)

Macro to declare network replication traits for a custom array type. This macro sets up the necessary properties for Unreal Engine's replication system to handle the serialization and deserialization of arrays in a network-efficient manner.

Usage & Implementation Notes

  • The DECLARE_STRUCT_OPS_TYPE_TRAITS macro is used to enable delta serialization for custom array types, which can significantly reduce the amount of data transmitted over the network when only small changes are made to the array.

  • This module should be included and utilized in any Unreal Engine project that requires efficient network replication of complex data structures.
