前提

有必要说一下，静态这块内容加载时我用UE5.2版本出现调用静态资源不是显示问题，修改后容易崩。所以，这里不建议5.2版本，直接用5.3，就不会出现这个问题。

导入初学者资源包

静态加载类和资源

静态加载资源

复制静态资源引用

}

编译后，会显示引用上

然后想，创建蓝图类BP_MyCustomActor

到这里，都显示引用上。

静态加载类

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "MyClasss")TSubclassOf<AActor> MyActorClass;

加载静态类时，在引用资源类的末尾需要加上 _C，否则编译时会报错

	// 静态加载类  加载静态类时，在引用资源类的末尾需要加上 _C，否则编译时会报错static ConstructorHelpers::FClassFinder<AActor> TempActorClass(TEXT("/Script/Engine.Blueprint'/Game/StarterContent/Blueprints/Blueprint_CeilingLight.Blueprint_CeilingLight_C'"));MyActorClass = TempActorClass.Class;UE_LOG(LogTemp, Warning, TEXT("MyActorClass is %s"), *MyActorClass->GetName());

编译后，创建蓝图，打开后打印日志

动态加载类和资源

动态资源

void AMyCustomActor::BeginPlay()
{Super::BeginPlay();// 动态加载资源UStaticMesh *TempStaticMesh = LoadObject<UStaticMesh>(nullptr, TEXT("/Script/Engine.StaticMesh'/Game/StarterContent/Shapes/Shape_NarrowCapsule.Shape_NarrowCapsule'"));if (TempStaticMesh){MyMeshComponent->SetStaticMesh(TempStaticMesh);}else{UE_LOG(LogTemp, Warning, TEXT("TempStaticMesh is null"));}
}

编译后，创建蓝图拖到场景中，点击运行
