BlueprintCallable
-
功能描述： 在蓝图中可以调用这个多播委托
-
元数据类型： bool
-
引擎模块： Blueprint
-
限制类型： Multicast Delegates
-
作用机制： 在PropertyFlags中加入CPF_BlueprintCallable
-
常用程度： ★★★
在蓝图中可以调用这个多播委托。
示例代码：
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FMyDynamicMulticastDelegate_One, int32, Value);
UPROPERTY(EditAnywhere, BlueprintReadWrite, BlueprintAssignable, BlueprintCallable)
FMyDynamicMulticastDelegate_One MyMulticastDelegateAssignAndCall;
UPROPERTY(EditAnywhere, BlueprintReadWrite, BlueprintCallable)
FMyDynamicMulticastDelegate_One MyMulticastDelegateCall;
UPROPERTY(EditAnywhere, BlueprintReadWrite, BlueprintAssignable)
FMyDynamicMulticastDelegate_One MyMulticastDelegateAssign;
UPROPERTY(EditAnywhere, BlueprintReadWrite)
FMyDynamicMulticastDelegate_One MyMulticastDelegate;
示例效果：
注意BlueprintAssignable和BlueprintCallable只能用于多播委托：
DECLARE_DYNAMIC_DELEGATE_OneParam(FMyDynamicSinglecastDelegate_One, int32, Value);
//编译报错：'BlueprintCallable' is only allowed on a property when it is a multicast delegate
UPROPERTY(EditAnywhere, BlueprintReadWrite, BlueprintCallable)
FMyDynamicSinglecastDelegate_One MyMyDelegate4;
//编译报错：'BlueprintAssignable' is only allowed on a property when it is a multicast delegate
UPROPERTY(EditAnywhere, BlueprintReadWrite, BlueprintAssignable)
FMyDynamicSinglecastDelegate_One MyMyDelegate5;
