+**BlueprintNativeEvents** 是 **UFUNCTION** 的一个函数说明符，作用是指定一个函数，使其可以在C++中实现，并且同时可以在蓝图中被重载
+
+与 **BlueprintImplementableEvents** 不同，它不仅可以有蓝图实现，而且可以拥有一个C++实现
+
+## 具体使用
+
+```cpp
+///Header (.h) function definition: 
+//Override in BP to extend the base C++ functionality!
+UFUNCTION(BlueprintNativeEvent, BlueprintCallable, Category="JoyBall")
+float GetArmorRating() const;
+
+/////////////////
+
+///Source (.cpp) function Implementation:
+float AJoyBall::GetArmorRating_Implementation() const
+{
+    //remember to call super / parent function in BP!
+    V_LOG("C++ Happens First");
+    return 100;
+}
+```
+
+在蓝图重载函数中，可以调用父函数来使用C++的实现，并在此基础上进行扩展，或者不调用父函数，完全重写此函数
