制作眩晕功能

添加眩晕标签

添加一个眩晕标签

CRUNCH_API UE_DECLARE_GAMEPLAY_TAG_EXTERN(Stats_Stun)

UE_DEFINE_GAMEPLAY_TAG_COMMENT(Stats_Stun, "Stats.Stun", "眩晕")

使用GE来定制眩晕的时长

创建一个GE设置一个定长的眩晕GE
在这里插入图片描述
造成伤害的GE处添加眩晕GE

输入AbilitySystem.DebugAbilityTags就能看到赋予的Tag

添加对眩晕标签的处理，以及添加眩晕动画

到角色基类中添加对接收眩晕Tag的处理

#pragma region GAS组件相关
private:// 眩晕标签的更新void StunTagUpdated(const FGameplayTag Tag, int32 NewCount);
#pragma endregion#pragma region 眩晕(Stun)
private:UPROPERTY(EditDefaultsOnly, Category = "Stun")UAnimMontage* StunMontage;virtual void OnStun();virtual void OnRecoverFromStun();
#pragma endregion

void ACCharacter::BindGASChangeDelegates()
{if (CAbilitySystemComponent){CAbilitySystemComponent->RegisterGameplayTagEvent(TGameplayTags::Stats_Dead).AddUObject(this, &ACCharacter::DeathTagUpdated);CAbilitySystemComponent->RegisterGameplayTagEvent(TGameplayTags::Stats_Stun).AddUObject(this, &ACCharacter::StunTagUpdated);}
}
void ACCharacter::StunTagUpdated(const FGameplayTag Tag, int32 NewCount)
{if (IsDead()) return;if (NewCount != 0){OnStun();PlayAnimMontage(StunMontage);}else{OnRecoverFromStun();StopAnimMontage(StunMontage);}
}void ACCharacter::OnStun()
{
}void ACCharacter::OnRecoverFromStun()
{
}

在子类中重写获得眩晕标签和移除眩晕标签的函数
CPlayerCharacter

#pragma region 眩晕(Stun)
private:virtual void OnStun();virtual void OnRecoverFromStun();
#pragma endregion

眩晕了无法操作跟死亡一样禁用玩家的输入，解除眩晕的时候判断一下是否死亡，不然就会诈尸了

void ACPlayerCharacter::OnStun()
{SetInputEnabledFromPlayerController(false);
}void ACPlayerCharacter::OnRecoverFromStun()
{if (IsDead()) return;SetInputEnabledFromPlayerController(true);
}

另外还需要处理AI

	// 监听Pawn眩晕Tag变化，控制AI逻辑启停void PawnStunTagUpdated(const FGameplayTag Tag, int32 Count);// 标记AI当前是否处于死亡状态bool bIsPawnDead = false;

在死亡标签变化的时候修改布尔变量

void ACAIController::OnPossess(APawn* InPawn)
{Super::OnPossess(InPawn);UAbilitySystemComponent* PawnASC = UAbilitySystemBlueprintLibrary::GetAbilitySystemComponent(InPawn);if (PawnASC){PawnASC->RegisterGameplayTagEvent(TGameplayTags::Stats_Dead, EGameplayTagEventType::NewOrRemoved).AddUObject(this, &ACAIController::PawnDeadTagUpdated);PawnASC->RegisterGameplayTagEvent(TGameplayTags::Stats_Stun).AddUObject(this, &ACAIController::PawnStunTagUpdated);}
}void ACAIController::PawnDeadTagUpdated(const FGameplayTag Tag, int32 Count)
{if (Count != 0){GetBrainComponent()->StopLogic("Dead"); // 停止死亡状态下的逻辑ClearAndDisableAllSenses(); // 清除感知数据bIsPawnDead = true;}else{GetBrainComponent()->StartLogic(); // 重新启动AI逻辑EnableAllSenses(); // 启用感知系统bIsPawnDead = false;}
}void ACAIController::PawnStunTagUpdated(const FGameplayTag Tag, int32 Count)
{if (bIsPawnDead) return;if (Count != 0){GetBrainComponent()->StopLogic("Stun");}else{GetBrainComponent()->StartLogic();}
}

在技能的基类中，从构造函数中添加阻止标签，眩晕不能用技能，再去被动技能中移除这个标签。

UCGameplayAbility::UCGameplayAbility()
{// 眩晕状态无法激活技能ActivationBlockedTags.AddTag(TGameplayTags::Stats_Stun);
}

UGAP_Launched::UGAP_Launched()
{// 设置网络执行策略为仅在服务器端执行NetExecutionPolicy = EGameplayAbilityNetExecutionPolicy::ServerOnly;// 创建一个新触发数据对象FAbilityTriggerData TriggerData;// 设置触发数据的触发源为游戏事件TriggerData.TriggerSource = EGameplayAbilityTriggerSource::GameplayEvent;// 设置触发数据的触发标签为击飞被动技能激活标签TriggerData.TriggerTag = GetLaunchedAbilityActivationTag();//TGameplayTags::Ability_Passive_Launch_Activate;// 移除被击飞技能的禁用眩晕标签ActivationBlockedTags.RemoveTag(TGameplayTags::Stats_Stun);// 将创建的触发数据添加到能力触发器列表中AbilityTriggers.Add(TriggerData);
}
