Actor范围内随机生成

1. 新建box组件

   SpawnArea = CreateDefaultSubobject<UBoxComponent>(TEXT("SpawnArea"));
   	RootComponent = SpawnArea;
   

2. 获取随机生成位置

   FVector AEnemySpawner::GetGenerateLocation()
   {
   	float Distance = 0;
   	FVector Location;
   	
   	while (Distance< MinimumDistanceToPlayer)
   	{
   		//在盒子中产生的随机的点
   		Location = UKismetMathLibrary::RandomPointInBoundingBox(SpawnArea->Bounds.Origin, SpawnArea->Bounds.BoxExtent);
   		Distance = (Location - SpaceShip->GetActorLocation()).Size();
   	}
   	return Location;
   }
   

3. 在指定位置生成Actor

   FActorSpawnParameters SpawnParameters;
   		//           生成敌人
   		GetWorld()->SpawnActor<AEnemy>(Enemy, GetGenerateLocation(), FRotator::ZeroRotator, SpawnParameters);
