This thread starts when I tried to set up Pulse on Unity (2018.3.14f1) to build a PC version that I can use with the HTC Vive. Got this message: “PulseUnityAsset | error CS0246: The type or namespace name `PulseEngine’ could not be found. Are you missing an assembly reference?”

I just made a new project with the steamVR asset and PulsePhysiologyEngine and I am having no issue on unity version 2019.1.2f1 I made a merged scene with the steamvr interactions\_Example and the VitalsMonitor scene.

What is your build target?

Also, did you have the Pulse Physiology Engine installed on the computer prior to import the unity package? 'cause in my case, I didn’t install the engine. I only tried to import Pulse package from assets store.

Build target is PC, HTC Vive for now.

I did not have anything installed before putting the unity package in.
Will you try making a new unity project with nothing in it and importing this package.

Then open the vive+pulse scene in the root of the project and let me know what happens. If you can see anything in the headset, if you can see any of the data on the monitors, anything you see.

Hi,
I’m working with pfgerard and we’re trying to get the pulse engine to work in Unity.
The problem comes at compilation time of the Pulse-Superbuild.sln.
I’m getting lots of errors, that point to missing libraries (Qt, BLAS, CUDA, etc.). My understanding is that you don’t need to install anything apart from CMake and Java, is that right? I followed the instructions here:
[https://gitlab.kitware.com/physiology/engine#build-environment](https://gitlab.kitware.com/physiology/engine#build-environment)
I assumed that the missing libraries are fetched and downloaded, but is that not the case?
Do I need to install Qt and others?
Thanks for your help,
Antoine

Hi Antoine
You can just pull the PulseUnity assest from the Unity store, you will not need to build Pulse, it’s all prebuilt and ready to go in the asset.
But if you really want to build the Pulse Asset from scratch, you can…
First thing you need to do is build Pulse, which is what you are doing
It is going to first pull Eigen and get it ready for use by the Pulse build.
That is Eigen configuring itself
Eigen can work with anything and attempts to find everything when its included in a CMake process
Its ok to have nothing it works with, but it will log everything it looks for and cannot find.
The error is in missing the Dirent package, which should have been pulled by the super build, but seems like it is not.
Can you take a look at this and see if it helps?
[https://gitlab.kitware.com/physiology/engine/wikis/Using%20MSVC](https://gitlab.kitware.com/physiology/engine/wikis/Using%20MSVC)
And just in case,
What MSVC version are you using and what version of CMake do you have?

Hi Aaron,
Thanks a lot for your quick reply, much appreciated!
That’s odd, the reason I tried to build Pulse is that they were missing libraries in the asset (Error CS0246 that pfgerard was referring to). So I figured out I needed to build the Pulse engine to generate these missing libraries.
I don’t particularly want to rebuild the Pulse engine, so am very happy with prebuilt libraries. Now, based on your reply, I can see that there are .dll files in the Plugins folder. So it might be a setup issue. Is it supposed to work out of the box or do I need to setup some specific path for Unity to compile properly?
Thank you,
Antoine

The Pulse Asset has a PulseUnityAssetUserManual.pdf as part of the download that will help you get things setup. The only thing you should have to do is copy some required files from the StreamingAssets folder (look for details in that pdf), but not having done that would not give you a dll load error. For some reason, maybe the Pulse Asset is not under your projects Assets folder?
Out of the box, adding in the Pulse Asset (from the unity store inside of Unity) to your game/project should put a Pulse asset folder under your assets folder. Unity should look in all Plugin folders under your project for all dlls and load the .NET dlls. So it should automatically find our .NET dlls.

Hi Aaron,
Sorry for my delayed reply, I didn’t get the chance to try the Pulse Engine again until today. And now, it’s working perfectly out-of-the-box!
So I’m kind of puzzled since both pfgerard and I tried it separately and got the same error message. And now, it just went away. So there must have been some weird glitch in the import of the assets and deleting the assets and re-importing seems to have fixed it…
Anyway, it’s working fine now. So thanks a lot again for your help and kindly taking the time to provide us guidance. Much appreciated!
Kind regards,
Antoine
