DECLARE_MULTICAST_DELEGATE(FMulticastDelegateSignature) 接着在类中声明一个 FMulticastDelegateSignature 成员 FMulticastDelegateSignature MyMulticastDelegate; 其次,创建一个新 Actor 类,命名为 MulticastDelegateListener 在其头文件中添加以下声明: FDelegateHandle MyDelegateHandle; UPROPERTY() UPointLightComponent*Poi...

DECLARE_DELEGATE_OneParam(FParamDelegateSignature,FLinearColor) 1. 注意:这个宏与之前稍有不同,后缀多出了一个_OneParam,而且我们还需要指定接受参数的类型——本例为 FLinearColor 接着再添加一个 FParamDelegateSignature 成员 FParamDelegateSignatureMyParameterDelegate; ...

1、当使用MULTICAST时,声明的代理事件类型需要声明为蓝图类型。不然报错,如: //声明代理 DECLARE_DYNAMIC_MULTICAST_DELEGATE_TwoParams(FLoadDesignsDelegateEvent, const TArray<FDesignInfo>&, _designsInfo, const bool, _result); //声明代理事件类型

① 委托的声明,书写格式遵循:DECLARE_[DYNAMIC]_[MULTICAST]_DELEGATE_[RetVal]_[XXXParam(s)],单词是有顺序的; ②单播委托在执行前务必判断是否有绑定委托函数,建议使用ExecuteIfBound,多播委托的广播执行是安全的,不论是否绑定了委托函数; ③多播委托所绑定的委托函数不能有返回值; ...
