UE5/C++ 基于GAS的Combo连击 4.1 创建连击接口

1.打开UE引擎，选择接口 C++类，命名为CombatInterface

 打开CombatInterface.h，创建两个方法接口

#pragma once

#include "CoreMinimal.h"
#include "UObject/Interface.h"
#include "CombatInterface.generated.h"

// This class does not need to be modified.
UINTERFACE(MinimalAPI,NotBlueprintable, BlueprintType, meta = (CannotImplementInterfaceInBlueprint))
class UCombatInterface : public UInterface
{
	GENERATED_BODY()
};

/**
 * 
 */
class SIMPLECOMBAT_API ICombatInterface
{
	GENERATED_BODY()

	// Add interface functions to this class. This is the class that will be inherited to implement this interface.
public:
    //用于连击攻击
	UFUNCTION(BlueprintCallable, Category = "Combat")
	virtual void CombatAttack(const FName& InKey) {};
    
    //用于获取连击检测结构体
	virtual struct FSimpleCombatCheck* GetSimpleCombatInfo() { return NULL;}
};
           

2.打开CharacterBase.h，继承这个接口

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Character.h"
#include "CombatInterface.h"//包含接口头文件
#include "MMOARPGCharacterBase.generated.h"

UCLASS()
class MMOARPGGAME_API AMMOARPGCharacterBase : public ACharacter,public ICombatInterface//继承接口
{
	GENERATED_BODY()

public:
	void NormalAttack(const FName& InKey);
    
    //继承至接口的CombatAttack方法
	virtual void CombatAttack(const FName& InKey);

    //继承至接口的GetSimpleCombatInfo方法
    virtual FSimpleCombatCheck* GetSimpleCombatInfo();
           

打开CharacterBase.cpp，实现这个方法

void AMMOARPGCharacterBase::NormalAttack(const FName& InKey)
{
	GetFightComponent()->NormalAttack(InKey);
}

void AMMOARPGCharacterBase::CombatAttack(const FName& InKey)
{
	NormalAttack(InKey);
}

FSimpleCombatCheck* AMMOARPGCharacterBase::GetSimpleCombatInfo()
{
	return GetFightComponent()->GetSimpleCombatInfo();
}
