Usage
For a same replicate object, you can use the push model for some replicated variables and the regular UE workflow for other variables (just be sure to set the value of bIsPushBased to the desired one before declaring vars in GetLifetimeReplicatedProps).
Replicate
In GetLifetimeReplicatedProps you must use a special struct
FDoRepLifetimeParams Params;
Params.bIsPushBased = true;
DOREPLIFETIME_WITH_PARAMS_FAST(AMyAwesomeActor, bMyReplicatedBool, Params);
...Use MARK_PROPERTY_DIRTY macros to mark a property as being dirty so it can be picked up to be replicated.
A useful macro that I made that i like is #define NET_MARKDIRTY(PropertyName) MARK_PROPERTY_DIRTY_FROM_NAME(ThisClass, PropertyName, this).
Use it for engine class
Some engine classes already use push based model (for e.g. Actor).
But some are not, but it can be changed through a cvar.
For example PlayerController and Controller looks for UE::Gameplay::CVars::bIsPlayerControllerPushBased and UE::Gameplay::CVars::bIsControllerPushBased to know what to use.
