+# Replicated
+
+- **功能描述：** 指定该属性应随网络进行复制。
+
+- **元数据类型：** bool
+- **引擎模块：** Network
+- **作用机制：** 在PropertyFlags中加入[CPF_Net](../../../Flags/EPropertyFlags/CPF_Net.md)
+- **常用程度：** ★★★★★
+
+## 示例代码：
+
+记得要在cpp代码中相应添加GetLifetimeReplicatedProps函数
+
+```jsx
+UCLASS(Blueprintable, BlueprintType)
+class INSIDER_API AMyProperty_Network :public AActor
+{
+public:
+	GENERATED_BODY()
+public:
+	UPROPERTY(EditAnywhere, BlueprintReadWrite)
+		int32 MyInt_Default = 123;
+
+		UPROPERTY(EditAnywhere, BlueprintReadWrite, Replicated)
+		int32 MyInt_Replicated = 123;
+		
+	UPROPERTY(EditAnywhere, BlueprintReadWrite, Replicated)
+		FMyReplicatedStruct MyStruct_Replicated;
+};
+
+void AMyProperty_Network::GetLifetimeReplicatedProps(TArray<FLifetimeProperty>& OutLifetimeProps) const
+{
+	Super::GetLifetimeReplicatedProps(OutLifetimeProps);
+	DOREPLIFETIME(AMyProperty_Network, MyInt_Replicated);
+	DOREPLIFETIME(AMyProperty_Network, MyStruct_Replicated);
+}
+```
+
+示例效果就不发了，这个是基本的网络标记。
