+# Blueprintable
+
+- **功能描述：**  可以在蓝图中实现
+- **元数据类型：** bool
+- **引擎模块：** Blueprint
+- **作用机制：** 在Meta中加入[IsBlueprintBase](../../../../Meta/Blueprint/IsBlueprintBase.md), [BlueprintType](../../../../Meta/Blueprint/BlueprintType.md)
+- **关联项：** [NotBlueprintable](../NotBlueprintable/NotBlueprintable.md)
+- **常用程度：★★★★★**
+
+是否可以在蓝图中实现。
+
+## 示例代码：
+
+```cpp
+UINTERFACE(Blueprintable,MinimalAPI)
+class UMyInterface_Blueprintable:public UInterface
+{
+	GENERATED_UINTERFACE_BODY()
+};
+
+class INSIDER_API IMyInterface_Blueprintable
+{
+	GENERATED_IINTERFACE_BODY()
+public:
+	UFUNCTION(BlueprintCallable, BlueprintImplementableEvent)
+	void Func_ImplementableEvent() const;
+
+	UFUNCTION(BlueprintCallable,BlueprintNativeEvent)
+	void Func_NativeEvent() const;
+};
+
+UINTERFACE(NotBlueprintable,MinimalAPI)
+class UMyInterface_NotBlueprintable:public UInterface
+{
+	GENERATED_UINTERFACE_BODY()
+};
+
+class INSIDER_API IMyInterface_NotBlueprintable
+{
+	GENERATED_IINTERFACE_BODY()
+public:
+//也不得定义蓝图函数，因为已经不能在蓝图中实现了
+//UFUNCTION(BlueprintCallable, BlueprintImplementableEvent)
+	//void Func_ImplementableEvent() const;
+
+//	UFUNCTION(BlueprintCallable,BlueprintNativeEvent)
+//	void Func_NativeEvent() const;
+};
+```
+
+## 示例效果：
+
+在蓝图中测试，发现UMyInterface_NotBlueprintable并不能找到。

+在Class Settings里的Interface里找不到不允许实现的接口。

+
+什么情况下需要用到该标记？虽然不能在蓝图中实现，但是依然可以在C++里实现，也可以通过反射判断一个对象是否实现该接口。
