Get Actor Position in Screen space in UE4

GetActorPosInScreenSpace.cpp

bool GetActorPosInScreenSpace(const APlayerController* Player, const AActor& Actor, FVector2D& OutScreenPos)
{
  FVector WorldPosition = Actor->GetActorLocation();
  ULocalPlayer* const LP = Player ? Player->GetLocalPlayer() : nullptr;
  if (LP && LP->ViewportClient)
  {
    // get the projection data
    FSceneViewProjectionData ProjectionData;
    if (LP->GetProjectionData(LP->ViewportClient->Viewport, eSSP_FULL, /*out*/ ProjectionData))
    {
      FMatrix const ViewProjectionMatrix = ProjectionData.ComputeViewProjectionMatrix();
      const bool bResult = FSceneView::ProjectWorldToScreen(WorldPosition, ProjectionData.GetConstrainedViewRect(), ViewProjectionMatrix, OutScreenPos);

      FPlane Result = ViewProjectionMatrix.TransformFVector4(FVector4(WorldPosition, 1.f));
      if (Result.W > 0.0f)
      {
        // the result of this will be x and y coords in -1..1 projection space
        const float RHW = 1.0f / Result.W;
        FPlane PosInScreenSpace = FPlane(Result.X * RHW, Result.Y * RHW, Result.Z * RHW, Result.W);

        OutScreenPos = FVector2D{ PosInScreenSpace.X, PosInScreenSpace.Y };
        return true;
      }
    }
  }
  OutScreenPos = FVector2D::ZeroVector;
  return false;
}

It works really well, thanks!!
I needed to change Actor& to Actor* to compile it. You can consider to fix it:

-bool GetActorPosInScreenSpace(const APlayerController* Player, const AActor& Actor, FVector2D& OutScreenPos)
+bool GetActorPosInScreenSpace(const APlayerController* Player, const AActor* Actor, FVector2D& OutScreenPos)
