UE5 C++ 动态创建组件component (非构造函数中也可以使用）

这里用样条线作为例子
USplineComponent* SplineComponent = NewObject(this, FName(TEXT("SplineC") + FString::FromInt(index++)));
SplineComponent->AttachToComponent(RootComponent, FAttachmentTransformRules::KeepRelativeTransform);
// 设置碰撞
//SplineComponent->SetCollisionEnabled(ECollisionEnabled::QueryAndPhysics);
//SplineComponent->SetCollisionObjectType(ECC_WorldDynamic);
//SplineComponent->SetCollisionResponseToChannel(ECC_GameTraceChannel1, ECollisionResponse::ECR_Overlap);
SplineComponent->RegisterComponentWithWorld(GetWorld());

// 清除样条线的点
SplineComponent->ClearSplinePoints();
