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)
