• Targets PhysX 4.1.0.25992954
• 64 bit version only
• Dependencies
  • .NET 4.7.1
  • C runtime 2019 - https://aka.ms/vs/16/release/VC_redist.x64.exe
• Remaining:
  • Vehicle sample and a few related classes
  • Attach/Detach shape from an actor

  • Broad Phase
  • Deletion Listener

Building

Dependencies

• Visual Studio 2019
• VC++ 2015.4 v140 toolset for desktop (x86,x64) - 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 repo directory is C:\NVIDIAGameWorks\PhysX
  • To specify an alternative location on your computer: define the environment variable NVIDIAPhysX41SDK. You can do this by running setx NVIDIAPhysX41SDK "C:\NVIDIAGameWorks\PhysX" /M (as administrator).
