[언리얼5/UE5] Setup Spawn Ability (능력 스폰 설정)

 

 

이렇게 GameplayAbiliy.h에 들어가면 Given과 End 함수를 찾을 수 있다.

이 함수들을 override하자

 

 

GameplayAbility.h

UENUM(BlueprintType)
enum class EWarriorAbilityActivationPolicy : uint8
{
	OnTriggered,
	OnGiven,
};

/**
 * 
 */
UCLASS()
class WARRIOR_API UWarriorGameplayAbility : public UGameplayAbility
{
	GENERATED_BODY()

protected:
	//~ Begin Ability Interface
	virtual void OnGiveAbility(const FGameplayAbilityActorInfo* ActorInfo, const FGameplayAbilitySpec& Spec) override;
	virtual void EndAbility(const FGameplayAbilitySpecHandle Handle, const FGameplayAbilityActorInfo* ActorInfo, const FGameplayAbilityActivationInfo ActivationInfo, bool bReplicateEndAbility, bool bWasCancelled) override;
	//~ End Ability Interface

	UPROPERTY(EditAnywhere, Category = "WarriorAbility")
	EWarriorAbilityActivationPolicy AbilityActivationPolicy = EWarriorAbilityActivationPolicy::OnTriggered;

};

 

ENum Class로 사용해서, 알맞은 정책을 선택해준다.

 

 

 

 

GameplayAbility.cpp

void UWarriorGameplayAbility::OnGiveAbility(const FGameplayAbilityActorInfo* ActorInfo, const FGameplayAbilitySpec& Spec)
{
	Super::OnGiveAbility(ActorInfo, Spec);

	if (AbilityActivationPolicy == EWarriorAbilityActivationPolicy::OnGiven)
	{ 
		if (ActorInfo && !Spec.IsActive())
		{
			ActorInfo->AbilitySystemComponent->TryActivateAbility(Spec.Handle);
		}
	}
}

void UWarriorGameplayAbility::EndAbility(const FGameplayAbilitySpecHandle Handle, const FGameplayAbilityActorInfo* ActorInfo, const FGameplayAbilityActivationInfo ActivationInfo, bool bReplicateEndAbility, bool bWasCancelled)
{
	Super::EndAbility(Handle, ActorInfo, ActivationInfo, bReplicateEndAbility, bWasCancelled);
	
	if (AbilityActivationPolicy == EWarriorAbilityActivationPolicy::OnGiven)
	{
		if (ActorInfo)
		{
			ActorInfo->AbilitySystemComponent->ClearAbility(Handle);
		}
	}
}

 

이렇게 OnGiven인지 정책을 먼저 확인하다.

맞으면 Ability를 활성화 시켜준다.

 

OnGiven에 대한 것이니, 끝날 때 능력을 Clear해준다.

 

 

이렇게 하면 알고리즘은 다 짠것이고,BP로 만들어주자

 

이렇게 해주면 무기 생성을 위한 기본적인 셋팅은 끝이다.
