第一种方式，是用样条线，简明扼要，但是打包后就消失了。

	AActor* actor = world->SpawnActor< AActor>(ActorClass);
	actor->AttachToActor(this, FAttachmentTransformRules::KeepRelativeTransform);
	USplineComponent* splineComponent = this->GenerateSplineComponent(info, radius,actor);
	splineComponent->AttachToComponent(actor->GetRootComponent(), FAttachmentTransformRules::KeepRelativeTransform);
	TArray<FVector> posArray;
			USplineComponent* splineComponent = this->GenerateSplineComponent(posArray,actor);
	splineComponent->AttachToComponent(actor->GetRootComponent(), FAttachmentTransformRules::KeepRelativeTransform);

USplineComponent* MyActor::GenerateSplineComponent(TArray< FVector> posArray, AActor* actor)
{

TArray<FVector> posXYZArray;
USplineComponent* splineTrack = NewObject<USplineComponent>(actor, TEXT("Spline"));
splineTrack->RegisterComponent();
//设置样本条的颜色
splineTrack->SetUnselectedS
