回到动画源中
进行攻击检测的动画通知改写
这里用到了蓝图接口
把蓝图接口改为C++
// Fill out your copyright notice in the Description page of Project Settings.
#pragma once
#include “CoreMinimal.h”
#include “UObject/Interface.h”
#include “Combat.generated.h”
// This class does not need to be modified.
UINTERFACE(MinimalAPI)
class UCombat : public UInterface
{
GENERATED_BODY()
};
/**
*
*/
class ROUGHLIKE1_API ICombat
{
GENERATED_BODY()
// Add interface functions to this class. This is the class that will be inherited to implement this interface.public:
//攻击重置
UFUNCTION(BlueprintNativeEvent, Category = “Combat”)
void INT_ResetAtk();
virtual void INT_ResetAtk_Implementation() = 0;
//攻击检测 UFUNCTION(BlueprintNativeEvent, Category = "Combat") void INT_AttackDetection(FVector boxPosition, FVector boxExtension); virtual void INT_AttackDetection_Implementation(FVector boxPosition, FVector boxExtension) = 0;};
再写动画通知类
// Fill out your copyright notice in the Description page of Project Settings.
#pragma once
#include “CoreMinimal.h”
#include “Notifies/PaperZDAnimNotify.h”
#include “ANZ_Attack.generated.h”
/**

UCLASS()
class ROUGHLIKE1_API UANZ_Attack : public UPaperZDAnimNotify
{
GENERATED_BODY()
public:
UANZ_Attack();
//攻击盒大小
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = “Attack”)
FVector BoxExtent;
//攻击位置的Socket名称
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = “Attack”)
FName socketName;
protected:
//重写动画通知的触发事件
virtual void OnReceiveNotify_Implementation(UPaperZDAnimInstance* OwningInstance) const override;
};
// Fill out your copyright notice in the Description page of Project Settings.
#include “AnimNotify/ANZ_Attack.h”
#include <Interface/Combat.h>
#include <PaperZDAnimInstance.h>
#include <MyPaperZDCharacter.h>
UANZ_Attack::UANZ_Attack()
{
BoxExtent = FVector(100.0f, 50.0f, 50.0f);
socketName = TEXT(“Socket_ATK”);
}
void UANZ_Attack::OnReceiveNotify_Implementation(UPaperZDAnimInstance* OwningInstance) const
{
if (!OwningInstance)
{
return;
}
//获取动画实例所属的actor
AActor* ownerActor = OwningInstance->GetOwningActor();
if (!ownerActor)
{
return;
}
//获取渲染组件，用来读取Socket位置
UActorComponent* ac = ownerActor->GetComponentByClass(USceneComponent::StaticClass());
if (!ac)
{
return;
}
USceneComponent* RenderComp = Cast(ac);
if (!RenderComp)
{
return;
}
//获取socket的世界位置
FVector socketLocation = RenderComp->GetSocketLocation(socketName);
if (ownerActor->Implements())
{
ICombat::Execute_INT_AttackDetection(ownerActor,socketLocation, BoxExtent);
}
}
由于这个蓝图接口是角色类调用的，
所以，在角色类重载
virtual void INT_AttackDetection_Implementation(FVector boxPosition, FVector boxExtension) override;由于还用到了其他蓝图接口，所以暂时让蓝图实现，即
// 扩展入口：蓝图 / C++ 均可重写， UFUNCTION(BlueprintNativeEvent, BlueprintCallable, Category = "Combat | Attack") void ProcessHitResult(AActor* Target, float Force); virtual void ProcessHitResult_Implementation(AActor* Target, float Force) {}void AMyPaperZDCharacter::INT_AttackDetection_Implementation( FVector boxPosition, FVector boxExtension)
{
//如果死亡，则返回
if (IsDead)
{
return;
}
//构建BoxOverlap参数
TArray<TEnumAsByte> objectTypes;
objectTypes.Add(EObjectTypeQuery::ObjectTypeQuery3); //pawn类型
//忽略玩家自身 TArray<AActor*> actorsToIgnore; actorsToIgnore.Add(this); //执行盒体检测 TArray<AActor*> outActors; bool bHasOverlap = UKismetSystemLibrary::BoxOverlapActors( this, boxPosition, boxExtension, objectTypes, nullptr, actorsToIgnore, outActors ); if (!bHasOverlap) { return; } //根据连击数设置推力 float force = (comboIndex == 0) ? 200.0f : 600.0f; //遍历所有重叠actor for (AActor* target : outActors ) { if (!target) { continue; } bool bIsEnemy = target->ActorHasTag(FName("enemy")); if (!bIsEnemy) { continue; } this->ProcessHitResult(target, force); }}
在蓝图中暂时保留
