通过反射调用UFunction函数，配合CustomThunk在UE5中创建带泛型参数的蓝图节点，实现代码如下：首先，声明函数并标记UFUNCTION，此标记表明函数需要通过CustomThunk进行调用，避免自动生成反射函数。使用DECLARE_FUNCTION自行定义，确保函数具有泛型参数Param。接下来，在函数定义中使用meta参数，例如：meta = (CustomStr...
而这里的Func函数指针,就指向了execMirrorBlueprintCallableFunction,在反射系统相关文章中,我们也粗略看过该函数的定义 DECLARE_FUNCTION(execMirrorBlueprintCallableFunction)\{\P_FINISH;\P_NATIVE_BEGIN;\this->MirrorBlueprintCallableFunction();\P_NATIVE_END;\} 最终直接调用了原生函数MirrorBlueprintCallableFunctio...
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(DynamicDelegateName, const TArray<FSelfDefinedStruct>&, StructArray); 1. 同样地,蓝图可调用函数中的参数若为TArray,也需要使用TArray的const引用,如: UFUNCTION(BlueprintCallable) void function(int32 par1, const TArray<FString>& strArr); 1. 2....
DECLARE_MULTICAST_DELEGATE[_Const, _RetVal, _etc.] (DelegateName) 多播代理绑定函数 广博: 调用函数Broadcast,但是调用不保证执行顺序的正确性 构建步骤: 使用宏构建代理类型 使用代理类型构建多播代理对象 添加绑定代理 执行调用 多播代理执行使用的是 Broadcast() 进行执行函数 ...
// declare light intensity variable UPROPERTY(VisibleAnywhere, Category = "Light Switch") float LightIntensity; // declare ToggleLight function UFUNCTION(BlueprintCallable, Category = "Light Switch") void ToggleLight(); }; 1. 2. 3. 4. ...
Super::TickComponent(DeltaTime, TickType, ThisTickFunction);//...} 这时候我们将该组件挂载在角色身上,已经有了效果,但是角色不知道组件生命值是否改变 接着我们在组件头文件的头文件申明下添加代理的宏定义,并创建一个代理对象 并在需要响应的函数中添加广播 ...
DECLARE_LOG_CATEGORY_EXTERN(YourAI, Log, All); //Logging for Critical Errors that must always be addressed DECLARE_LOG_CATEGORY_EXTERN(YourCriticalErrors, Log, All); 这样输出的Log你就可以知道是哪个部分的,这也是UE_Log很有用的原因。 在你的游戏Cpp文件中: ...
