bullet3/examples/SharedMemory/PhysicsServerCommandProcessor.h
erwincoumans 8e496036c6 More work on the C/C++ plugin system for pybullet/C-API:
Add preTickPluginCallback/postTickPluginCallback
User pointer for b3PluginContext, to store objects (class/struct instances)
Pass ints and floats as optional argument for plugin executePluginCommand
