Project could not be compiled try rebuilding from source manually

Hello
After i updated my visual studio i tried to create a c++ file in ue4 and it failed, so i tried deleting .vs, saved, Intermidate etc and the .sln file multiple times and rebuilding. But it keeps falling, the log says something about UPhysicalMaterial and SurfaceType but i dont get any errors in the code so i have no idea how to fix it.

This is the log from saved folder:

My ProjectXWeapon cpp file


Try to clean your project. You find it under Build in top bar in visual studio.

Hello, i have tried this :smiley:

I have commented out the phsicalsurface/surfacetype code and i can now succesfully rebuild the project. What is wrong with the code? I still dont get any code errors.

The docs for that

Say that is within the PhysicsCore module, so you would need to add that to your Build.cs file that’s within your project’s Source folder.
