1 定义并实现交互接口

接口定义：

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

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

// This class does not need to be modified.
UINTERFACE(MinimalAPI)
class UMyInterActInterface : public UInterface
{
	GENERATED_BODY()
};

/**
 * 
 */
class ARPG_CPLUS_API IMyInterActInterface
{
	GENERATED_BODY()

	// Add interface functions to this class. This is the class that will be inherited to implement this interface.
public:
	UFUNCTION(BlueprintCallable, BlueprintNativeEvent)
	void OnInterAct(APawn* InstigatorPawn);
};

实现接口：

class ARPG_CPLUS_API AInterActTrigger : public AActor,public IMyInterActInterface
{
	GENERATED_BODY()
	
public:	
	// Sets default values for this actor's properties
	AInterActTrigger();

	virtual void OnInterAct_Implementation(APawn* InstigatorPawn)override;
    .......

}

实现里绑定碰撞函数，重叠时设置指针：

// Fill out your copyright notice in the Description page of Project Settings.


#include "InterAct/InterActTrigger.h"
#include "Components/BoxComponent.h"
#include "Player/MyPlayer.h"
// Sets default values
AInterActTrigger::AInterActTrigger()
{
 	// Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
	PrimaryActorTick.bCanEverTick = true;
	// 创建 BoxCollision 组件
	BoxCollision = CreateDefaultSubobject<UBoxComponent>(TEXT("BoxCollision"));
	BoxCollision->SetupAttachment(RootComponent); // 绑定到根组件
	BoxCollision->S
