[游戏开发]UE5/C++ 基于GAS的Combo连击 4.5 使用AnimNotifyState检测连击

1.创建AnimNotifyState C++类，命名为AnimNotifyState_ComboCheck

?2.打开AnimNotifyState_ComboCheck.h

#pragma once

#include "CoreMinimal.h"
#include "Animation/AnimNotifies/AnimNotifyState.h"
#include "AnimNotifyState_ComboCheck.generated.h"

/**
 * 
 */
UCLASS()
class SIMPLECOMBAT_API UAnimNotifyState_ComboCheck : public UAnimNotifyState
{
	GENERATED_BODY()
	
public:
    //AnimNotifyState基础三件套
	virtual void NotifyBegin(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation, float TotalDuration);
	virtual void NotifyTick(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation, float FrameDeltaTime);
	virtual void NotifyEnd(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation);
    
    //技能名，需要在蓝图中配置
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AnimNotifyState_CheckCombo")
	FName CombatKey;
};

进行实现

#include "AnimNotifyState/AnimNotifyState_ComboCheck.h"
#include "SimpleCombatType.h"
#include "CombatInterface/CombatInterface.h"

void UAnimNotifyState_ComboCheck::NotifyBegin(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation, float TotalDuration)
{
	Super::NotifyBegin(MeshComp, Animation, TotalDuration);

	if (ICombatInterface* InCharacter = Cast<ICombatInterface>(MeshComp->GetOuter()))
	{
		InCharacter->GetSimpleCombatInfo()->bShortPress = false;
		InCharacter->GetSimpleCombatInfo()->UpdateCombatIndex();
	}

}

void UAnimNotifyState_ComboCheck::NotifyTick(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation, float FrameDeltaTime)
{
	Super::NotifyTick(MeshComp, Animation, FrameDeltaTime);
}

void UAnimNotifyState_ComboCheck::NotifyEnd(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation)
{
	Super::NotifyEnd(MeshComp, Animation);

	if (ICombatInterface* InCharacter = Cast<ICombatInterface>(MeshComp->GetOuter()))
	{
        //长按或短按，任一为true即可
		if ((InCharacter->GetSimpleCombatInfo()->bLongPress || InCharacter->GetSimpleCombatInfo()->bShortPress))
		{
			InCharacter->CombatAttack(CombatKey);
		}
	}
}

3.配置动画通知

打开UE引擎，打开角色连击动画Montage，在动画通知轨道添加ComboCheck动画通知

在动画通知combatKey?中填写技能名
