3. FAkBlueprintDelegateEventCallbackPackage Package子类, 增加了动态多播代理,可以绑定模块外和蓝图层的回调函数 /** 多播代理 */ FOnAkPostEventCallback BlueprintCallback /** 代理原型 */ DECLARE_DYNAMIC_DELEGATE_TwoParams(FOnAkPostEventCallback, EAkCallbackType, CallbackType, UAkCallbackInfo*, Cal...
() TMap<FName,URedPointClass*> Children; //节点key UPROPERTY() FName PointKey=NAME_None; //红点数量 UPROPERTY(BlueprintReadOnly,EditAnywhere) int32 PointCount=0; //定义一个委托,这个委托是用来通知表现层修改 DECLARE_DYNAMIC_DELEGATE_TwoParams(FOnRedPointCountChange,int32,Count,URedPointClass...
接着,我们在技能面板里定义一个新的委托类型,专门用于广播技能描述 DECLARE_DYNAMIC_MULTICAST_DELEGATE_TwoParams(FSpellDescriptionSignature, FString, SpellDescription, FString, SpellNextLevelDescription); //技能描述委托 1. 并在类里添加一个委托变量 UPROPERTY(BlueprintAssignable) FSpellDescriptionSignature SpellD...
DECLARE_DYNAMIC_MULTICAST_DELEGATE_TwoParams(DynamicDelegateName, Param1Type, Param1Name, Param1Type, Param2Name); 1. 2. 3. 4. 5. 为了动态代理能够在Blueprint中使用,则自然需要在声明对应的变量的时候添加UPROPERTY([specifiers])。其中可用于多播代理的Specifier有BlueprintAssignable、BlueprintAuthorityOnly...
通过DECLARE_DYNAMIC_MULTICAST_DELEGATE_TwoParams来定义事件,该方法实现了动态委托的定义,动态委托允许动态绑定,它可以序列化,也就是说可以在蓝图中使用。 事件调用,直接在原生绑定的事件函数里面进行处理 7 这里定义了显示的释放方法供应用层调用,另外还需要调用SetReadyToDestroy函数,因为继承自UBlueprintAsyncActionBase...
DECLARE_DYNAMIC_MULTICAST_DELEGATE_TwoParams(FOnHealthChangeDelegate,float,Health,float,MaxHealth);classTest{floathealth,maxHelth;FOnHealthChangeDelegate OnHealthChange;//定义voidPostHealthChange();//在此函数调用该委托}voidTest::PostHealthChange(){OnHealthChange.Broadcast(health,maxHealth);//调用该委托,...

DECLARE_DYNAMIC_MULTICAST_DELEGATE[_Const, _RetVal, etc.]( DelegateName ) 操作函数: BindDynamic( UserObject, FuncName ) 在动态代理上调用BindDynamic()的辅助宏。 AddDynamic( UserObject, FuncName ) 在动态多播代理上调用AddDynamic()的辅助宏。
