虚幻引擎5 GAS开发俯视角RPG游戏 P06-09 玩家等级与战斗接口

一.创建一个变量Level:

1.英雄在PlayState类

 Source/CC_Aura/Public/Player/CC_PlayerState.h:

(1)定义变量

private:UPROPERTY(VisibleAnywhere, ReplicatedUsing = OnRep_Level)int32 Level;

(2)复制回调函数:

	UFUNCTION()void OnRep_Level(int32 OldLevel);

void ACC_PlayerState::OnRep_Level(int32 OldLevel)
{}

(3)复制策略:

public:// 用于声明哪些变量需要在服务器和客户端之间自动复制‌virtual void GetLifetimeReplicatedProps(TArray<FLifetimeProperty>& OutLifetimeProps) const override;

void ACC_PlayerState::GetLifetimeReplicatedProps(TArray<FLifetimeProperty>& OutLifetimeProps) const
{Super::GetLifetimeReplicatedProps(OutLifetimeProps);DOREPLIFETIME(ACC_PlayerState, Level);
}

2.敌人在角色类

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Enemy Level")int32 Level;

二. 创建战斗接口:

1.创建接口函数:

Source/CC_Aura/Public/Interations/CC_CombatInterface.h:

public:virtual int32 GetCharacterLevel();

int32 ICC_CombatInterface::GetCharacterLevel()
{return 0;
}

2.角色基类继承接口:

class CC_AURA_API ACC_CharacterBase : public ACharacter,public IAbilitySystemInterface, public ICC_CombatInterface

3.敌人类实现接口函数:

Source/CC_Aura/Public/Characters/CC_EnemyCharacter.h

	/*ICC_CombatInterface接口函数:*		1.获取角色等级*/
#pragma region ICC_CombatInterfacevirtual int32 GetCharacterLevel() override;#pragma endregion

int32 ACC_EnemyCharacter::GetCharacterLevel()
{return Level;
}

4.英雄类实现战斗接口函数:

/*ICC_CombatInterface接口函数:
*		1.获取角色等级
*/
#pragma region ICC_CombatInterfacevirtual int32 GetCharacterLevel() override;#pragma endregion

int32 ACC_HeroCharacter::GetCharacterLevel()
{if (CCPlayerState == nullptr){CCPlayerState = GetPlayerState<ACC_PlayerState>();	//获取玩家状态}return CCPlayerState->GetCharacterLevel();
}

显然,我们要先在CCPlayerState类里定义GetCharacterLevel()函数:

Source/CC_Aura/Public/Player/CC_PlayerState.h

public:FORCEINLINE int32 GetCharacterLevel() const {return Level;}
