Can you replicate a struct with a pointer to an Actor

#Yes

If the actor pointer you are replicating is pointing to an actor that is already set to bReplicates=true, then yes you can replicate that actor pointer in a USTRUCT

just make sure the Actor* is UPROPERTY()

Also make sure to set the pointer to null yourself since USTRUCTS wont do that for you and can cause your game to crash otherwise!

#Code For You

USTRUCT()
struct FYourNetStruct
{
	GENERATED_USTRUCT_BODY()

	UPROPERTY() //<~~~ Required for replication
	AActor* ReplicatedActorPtr;
	//As long as this actor has bReplicates=true, this ptr will replicate properly
	// when this struct is passed over the network!
	
	UPROPERTY()
	float DamageAmount;
	
	UPROPERTY()
	FVector_NetQuantize100 HitLocation;
	
	FYourNetStruct()
	{
		ReplicatedActorPtr = nullptr;  //You must init this to avoid crashes -Rama
		
		HitLocation = FVector::ZeroVector;
		DamageAmount = 0;
	}
	
};
