网站制作设计收费标准,什么颜色做网站显的大气,云上的网站怎么做等保,外呼系统1.创建该类的子类 然后重启项目#xff0c;再创建子类的子类 再创建一个UI用于敌人 创建一个接口 2.然后打开Warriorplayer和EnemyCharacter实现ui组件
//UIUPROPERTY(EditDefaultsOnly, BlueprintReadOnly, Category Combat, meta (AllowPrivateAccess 再创建子类的子类 再创建一个UI用于敌人 创建一个接口 2.然后打开Warriorplayer和EnemyCharacter实现ui组件
//UIUPROPERTY(EditDefaultsOnly, BlueprintReadOnly, Category Combat, meta (AllowPrivateAccess true))UPlayerUIComponent* PlayerUIComponent;
PlayerUIComponent CreateDefaultSubobjectUPlayerUIComponent(TEXT(PlayerUIComponent));
UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category UI)UEnemyUIComponent* EnemyUIComponent;
EnemyUIComponent CreateDefaultSubobjectUEnemyUIComponent(EnemyUIComponent);
3.打开PawnUIInterface
public:virtual UPawnUIComponent* GetPawnUIComponent() const 0;
打开CHaracterBase继承此接口 //Begin IUIPawnInterface Interfacevirtual UPawnUIComponent* GetPawnUIComponent() const override;//End IUIPawnInterface Interface
UPawnUIComponent* ACharacterBase::GetPawnUIComponent() const
{return nullptr;
}
然后打开WarriorPlayer做同样的事
//Begin IUIPawnInterface Interfacevirtual UPawnUIComponent* GetPawnUIComponent() const override;//End IUIPawnInterface Interface
UPawnUIComponent* AWarriorPlayer::GetPawnUIComponent() const
{return PlayerUIComponent;
}
打开EnemyBase做同样的事
//Begin IUIPawnInterface Interfacevirtual UPawnUIComponent* GetPawnUIComponent() const override;//End IUIPawnInterface Interface
UPawnUIComponent* AEnemyBase::GetPawnUIComponent() const
{return EnemyUIComponent;
}
4.接下来对数值进行广播
打开PawnUIComponent.h,创建好委托
//当值的百分比发生变化时
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnPercentChangedDelegate, float, NewPercent);UPROPERTY(BlueprintAssignable)FOnPercentChangedDelegate OnCurrentHealthChanged;
然后进入PlayerUIComponent.h为Rage单独创建一个委托因为这个东西是只有玩家才有怪物没有
UPROPERTY(BlueprintAssignable)FOnPercentChangedDelegate OnCurrentRageChanged;
然后进入PawnUiInterface.h
virtual UPlayerUIComponent* GetPlayerUIComponent() const;
UPlayerUIComponent* IPawnUIInterface::GetPlayerUIComponent() const
{return nullptr;
}
进入WarriorPlayer覆写此函数
virtual UPlayerUIComponent* GetPlayerUIComponent() const override;
UPlayerUIComponent* AWarriorPlayer::GetPlayerUIComponent() const
{return PlayerUIComponent;
}
接着进入XMBAttributeSet,先创建一个用于存储当前Pawn对象的变量
private://用于存储当前的PawnUIInterfaceTWeakInterfacePtrIPawnUIInterface CachedPawnUIInterface;
然后需要在数值发生变化时先获取到当前对象的PawnUIComponent
void UXMBAttributeSet::PostGameplayEffectExecute(const struct FGameplayEffectModCallbackData Data)
{
//获取到目标的UIComponent则可以用广播if (!CachedPawnUIInterface.IsValid()){CachedPawnUIInterface TWeakInterfacePtrIPawnUIInterface(Data.Target.GetAvatarActor());}checkf(CachedPawnUIInterface.IsValid(), TEXT(%s didnt implement IPawnUIInterface),*Data.Target.GetAvatarActor()-GetActorNameOrLabel());UPawnUIComponent* PawnUIComponent CachedPawnUIInterface-GetPawnUIComponent();checkf(PawnUIComponent,TEXT(Couldnt extrac a PawnUiComponent from %s),*Data.Target.GetAvatarActor()-GetActorNameOrLabel());
}
然后在生命发生变化时
//Data.EvaluatedData.Attribute是当前被修改的属性if (Data.EvaluatedData.Attribute GetCurrentHealthAttribute())//找到正在修改的属性{const float NewCurrentHealth FMath::Clamp(GetCurrentHealth(),0.f, GetMaxHealth());SetCurrentHealth(NewCurrentHealth);//广播变化后的生命PawnUIComponent-OnCurrentHealthChanged.Broadcast(GetCurrentHealth()/GetMaxHealth());}
当体力发生变化时需要现货区到玩家的UIComponent
if (UPlayerUIComponent* PlayerUIComponent CachedPawnUIInterface-GetPlayerUIComponent()){PlayerUIComponent-OnCurrentRageChanged.Broadcast(GetCurrentRage()/GetMaxRage());}
最后在设置当前生命后再广播一次当前生命
SetCurrentHealth(NewCurrentHealth);const FString DebugString FString::Printf(TEXT(OldHealth : %f, damage Done :%f, NewCurrentHealth:%f),OldHealth,DamageDone,NewCurrentHealth);//将当前生命广播出去不管变没变化都要广播PawnUIComponent-OnCurrentHealthChanged.Broadcast(GetCurrentHealth()/GetMaxHealth());
5.启动项目创建一个UserWidget的C类 然后创建两个函数
protected:virtual void NativeOnInitialized() override;UFUNCTION(BlueprintImplementableEvent, meta (DisplayName On Owning Player UI Component Initialized))void BP_OnOwningPlayerUIComponentInitialized(UPlayerUIComponent* OwningPlayerUIComponent);
void UWarriorWidgetBase::NativeOnInitialized()
{Super::NativeOnInitialized();if (IPawnUIInterface* PawnUIInterface CastIPawnUIInterface(GetOwningPlayerPawn())){if (UPlayerUIComponent* PlayerUIComponent PawnUIInterface-GetPlayerUIComponent()){BP_OnOwningPlayerUIComponentInitialized(PlayerUIComponent);}}}
6.这一步要进行敌人widget的初始化首先进入pawnuiinterface为敌人写一个获取uicompnent的函数
virtual UEnemyUIComponent* GetEnemyUIComponent() const;
UEnemyUIComponent* IPawnUIInterface::GetEnemyUIComponent() const
{return nullptr;
}
然后进入EnemyBase内进行覆写
virtual UEnemyUIComponent* GetEnemyUIComponent() const;
UEnemyUIComponent* AEnemyBase::GetEnemyUIComponent() const
{return EnemyUIComponent;
}
再回到WarriorWidgetBase创建两个函数
public://为敌人创建的UFUNCTION(BlueprintCallable)void InitEnemyCreatedWidget(AActor* OwningEnemyActor);
protected:
UFUNCTION(BlueprintImplementableEvent, meta (DisplayName On Owning Enemy UI Component Initialized))void BP_OnOwningEnemyUIComponentInitialized(UEnemyUIComponent* OwningEnemyUIComponent);
void UWarriorWidgetBase::InitEnemyCreatedWidget(AActor* OwningEnemyActor)
{if (IPawnUIInterface* PawnUIInterface CastIPawnUIInterface(OwningEnemyActor)){//获取Enemy的UIComponentUEnemyUIComponent* EnemyUIComponent PawnUIInterface-GetEnemyUIComponent();checkf(EnemyUIComponent, TEXT(Failed to extrac an EnemyUIComponent from %s),*OwningEnemyActor-GetActorNameOrLabel());BP_OnOwningEnemyUIComponentInitialized(EnemyUIComponent);}
}
