Usage

Runtime files

You must have PhysX_64.dll, PhysXCommon_64.dll, PhysXCooking_64.dll, PhysXFoundation_64.dll and Ijwhost.dll in the same directory as your executable.

There is a helper .targets file which will add links of these to the root of your project. Each file has Copy to Output Directory set.

In your .csproj file:

1. Set the GeneratePathProperty="true" attribute on the PhysX.Net <PackageReference /> node.
   • e.g. <PackageReference Include="PhysX.Net" Version="5.0.1-alpha1" GeneratePathProperty="true" />
2. Add the follow to your .csproj file:

<ImportGroup>
    <Import Project="$(PkgPhysX_Net)\lib\RuntimeFiles.targets"/>
</ImportGroup>

Building

Dependencies

• Visual Studio 2022
• VC++ v143 toolset for desktop - needed to build PhysX itself. If you've built PhysX already, this could be ignored.

Compiling

Compile PhysX

• Clone the PhysX repo
• Run generate_projects.bat from the physx directory
• Open the solution and select the debug configuration
• You'll need to change all the PhysX projects to use Multi-threaded Debug DLL in order for them to be consumed by .NET
  • Select the projects in the solution explorer, right click, properties, C/C++, Code Generation and change Runtime Library to Multi-threaded Debug DLL (/MDd)

Compile PhysX.Net

• Clone this repo
• The default location of the PhysX 4.1.2 repo directory is C:\NVIDIAGameWorks\PhysX
  • To specify an alternative location on your computer: define the environment variable NVIDIAPhysX411SDK. You can do this by running setx NVIDIAPhysX411SDK "C:\NVIDIAGameWorks\PhysX" /M (as administrator).
