继承关卡基类 ALevelScriptActor 去扩展，蓝图继承自己的自定义关卡类

MyLevel.h

#pragma once#include "MyLevel.generated.h"UCLASS()class AMyLevel : public ALevelScriptActor{    GENERATED_BODY()public:    AMyLevel();    virtual ~AMyLevel();    virtual void BeginPlay() override;    virtual void Destroyed() override; public:    UFUNCTION(BlueprintCallable, Category = "AMyLevel")        FString GetLevelName() { return LevelName; }public:    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AMyLevel")        FString LevelName;    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AMyLevel")        int32 LevelCounter;};

MyLevel.cpp

#include "MySkeleton.h"#include "MyLevel.h"AMyLevel::AMyLevel() : Super(){    LevelName = "AMyLevel";    LevelCounter = 123;}AMyLevel::~AMyLevel(){    UE_LOG(LogMySkeleton, Warning, TEXT("--- AMyLevel::~AMyLevel"));}void AMyLevel::BeginPlay(){    UE_LOG(LogMySkeleton, Warning, TEXT("--- AMyLevel::BeginPlay"));}void AMyLevel::Destroyed(){    UE_LOG(LogMySkeleton, Warning, TEXT("--- AMyLevel::Destroyed"));}

关卡蓝图中继承这个自定义关卡类
- 修改父类
- 显示父类的变量

相关api

调用关卡中的事件

    virtual bool RemoteEvent(FName EventName);

从源码中可以看出，它是重当前 World 中的 所有Level 中查找显示状态中的且事件参数为零的事件，并执行它。

for( TArray<ULevel*>::TConstIterator it = GetWorld()->GetLevels().CreateConstIterator(); it; ++it )if( CurLevel && CurLevel->bIsVisible )if( EventTarget && EventTarget->NumParms == 0)
