Hi!  
I’m trying to use code from this wiki page:

> **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)**
>
> After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — ue4community.wiki! You will be able to find content from the official...

Everything looks good except that I’m getting this error

```
 error C3861: 'P2UVector': identifier not found

```

I included this headers to cpp

```
#include "PhysicsEngine/BodySetup.h"
#include "PhysicsPublic.h"
#include "PhysXIncludes.h"
#include "ThirdParty/PhysX/PhysX-3.3/include/geometry/PxTriangleMesh.h"
#include "ThirdParty/PhysX/PhysX-3.3/include/foundation/PxSimpleTypes.h"
#include "ApexDestructibleAssetImport.h" 

```

“PhysX” and “APEX” modules are also added.  
Any ideas?
