ue4-自定义关卡类

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)
