RPG17.蓝图函数库与轻重攻击连击

news 来源：原创 2025/6/2 22:07:20

1.创建蓝图函数库

XMBWarriorFunctionLibrary.h


#pragma once#include "CoreMinimal.h"
#include "Kismet/BlueprintFunctionLibrary.h"
#include "AbilitySystem/XMBAbilitySystemComponent.h"
#include "XMBWarriorFunctionLibrary.generated.h"UENUM()
enum class EXMBWarriorConfirmType : uint8
{Yes,No
};/*** */
UCLASS()
class ARPG_GRIVITY_API UXMBWarriorFunctionLibrary : public UBlueprintFunctionLibrary
{GENERATED_BODY()
public:static UXMBAbilitySystemComponent* NativeGetXMBPlayerASCFromActor(AActor* InActor);UFUNCTION(BlueprintCallable, Category = "XMBWorrior|FunctionLibrary")static void AddGameplayTagToActorIfNone(AActor* InActor, FGameplayTag TagToAdd);UFUNCTION(BlueprintCallable, Category = "XMBWorrior|FunctionLibrary")static void RemoveGameplayFromActorIfFound(AActor* InActor, FGameplayTag TagToRemove);static bool NativeDoesActorHaveTag(AActor* InActor, FGameplayTag TagToCheck);UFUNCTION(BlueprintCallable, Category = "XMBWorrior|FunctionLibrary", meta = (DisplayName = "Does Actor Have Tag", ExpandEnumAsExecs = "OutConfirmType"))static void BP_DoesActorHaveTag(AActor* InActor, FGameplayTag TagToCheck, EXMBWarriorConfirmType& OutConfirmType);
};

XMBWarriorFunctionLibrary.cpp

// Fill out your copyright notice in the Description page of Project Settings.#include "XMBWarriorFunctionLibrary.h"
#include "AbilitySystemBlueprintLibrary.h"
#include "AbilitySystem/XMBAbilitySystemComponent.h"UXMBAbilitySystemComponent* UXMBWarriorFunctionLibrary::NativeGetXMBPlayerASCFromActor(AActor* InActor)
{check(InActor);//从Actor中获取ASC//在内部检查是否实现了IAbilitySystemInterfacereturn Cast<UXMBAbilitySystemComponent>(UAbilitySystemBlueprintLibrary::GetAbilitySystemComponent(InActor));
}void UXMBWarriorFunctionLibrary::AddGameplayTagToActorfNone(AActor* InActor, FGameplayTag TagToAdd)
{UXMBAbilitySystemComponent* ASC = NativeGetXMBPlayerASCFromActor(InActor);if (ASC->HasMatchingGameplayTag(TagToAdd)){ASC->AddLooseGameplayTag(TagToAdd);}
}void UXMBWarriorFunctionLibrary::RemoveGameplayFromActorIfFound(AActor* InActor, FGameplayTag TagToRemove)
{UXMBAbilitySystemComponent* ASC = NativeGetXMBPlayerASCFromActor(InActor);if (ASC->HasMatchingGameplayTag(TagToRemove)){ASC->RemoveLooseGameplayTag(TagToRemove);}
}bool UXMBWarriorFunctionLibrary::NativeDoesActorHaveTag(AActor* InActor, FGameplayTag TagToCheck)
{UXMBAbilitySystemComponent* ASC = NativeGetXMBPlayerASCFromActor(InActor);return ASC->HasMatchingGameplayTag(TagToCheck);
}void UXMBWarriorFunctionLibrary::BP_DoesActorHaveTag(AActor* InActor, FGameplayTag TagToCheck,EXMBWarriorConfirmType& OutConfirmType)
{OutConfirmType = NativeDoesActorHaveTag(InActor, TagToCheck) ? EXMBWarriorConfirmType::Yes : EXMBWarriorConfirmType::No;
}

3.接下来轻重攻击，做成的效果是：当轻击第三下后，再点击重击，此时打出重击最后一下。

打开GA_LightAttack，三处改动位置
