Link: https://github.com/NVIDIAGameWorks/PhysX
Compile switch: EZ_BUILD_PHYSX
NVIDIA PhysX is used to provide collision detection, physics simulation, character controllers and other interactions.
To build PhysX yourself:
- Checkout https://github.com/NVIDIAGameWorks/PhysX.git
- Goto physx/buildtools/presets/public and open all presets that you want to build and change or add
<cmakeSwitch name="NV_USE_STATIC_WINCRT" value="False" comment="Use the statically linked windows CRT" />
<cmakeSwitch name="NV_USE_DEBUG_WINCRT" value="True" comment="Use the debug version of the CRT" /> - Run physx/generate_projects.bat for every configuration you want to build
- Open physx/compiler/.../PhysXSDK.sln and compile CMakePredefinedTargets/INSTALL for both debug and release
- Uwp installs are missing two include folders: PhysX/include/cudamanager and PhysX/include/gpu so copy those from physx/include to physx/install/.../PhysX/include
- The content of the built configuration in physx/install is now ready to be consumed by ezEngine by pointing the advanced cmake var EZ_PHYSX_SDK to it.
Important:
Depending on how you use PhysX, you may need to acquire (buy) a license for it from NVIDIA.
