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);
