虚幻引擎5 GAS开发俯视角RPG游戏 P07-02 授予能力

1.创建GA类:

2.在角色基类增加一个函数，用于应用技能

/*
 * 角色能力
 */
#pragma region Abilities
	
protected:
	void AddCharacterAbilities();
	
	UPROPERTY(EditDefaultsOnly, BlueprintReadOnly, Category="CC|Abilities")
	TArray<TSubclassOf<UGameplayAbility>> StartupAbilities;			//初始能力

#pragma endregion

void ACC_CharacterBase::AddCharacterAbilities()
{
	if (CC_AbilitySystemComponent == nullptr)
	{
		CC_AbilitySystemComponent = CastChecked<UCC_AbilitySystemComponent>(AbilitySystemComponent);
	}
	CC_AbilitySystemComponent->AddCharacterAbilities(StartupAbilities);
}

3.能力系统组件类添加函数:

	/*
	 * 角色能力
	 */
#pragma region Abilities
	
public:
	void AddCharacterAbilities(const TArray<TSubclassOf<UGameplayAbility>>& StartupAbilities);

#pragma endregion

void UCC_AbilitySystemComponent::AddCharacterAbilities(const TArray<TSubclassOf<UGameplayAbility>>& StartupAbilities)
{
	for (const TSubclassOf<UGameplayAbility>& AbilityClass : StartupAbilities)
	{
		FGameplayAbilitySpec AbilitySpec = FGameplayAbilitySpec(AbilityClass, 1);
		GiveAbilityAndActivateOnce(AbilitySpec);
	}
}

4.服务器初始化能力系统组件时调用方法:

Source/CC_Aura/Private/Characters/CC_HeroCharacter.cpp

void ACC_HeroCharacter::PossessedBy(AController* NewController)
{
	Super::PossessedBy(NewController);
	//服务器端初始化ASC
	InitCharacterASC();

	AddCharacterAbilities();		//添加能力
}

5.蓝图创建能力类:

6.角色添加能力:
