Adding to PythonAPI - help with boost needed

[roque2205]

Hi there,
I'm trying to add some functionalities to the PythonAPI, but I can't work out how to define API calls with more than one argument in PythonAPI/carla/source/libcarla/Actor.cpp.

Background info: I have created a class that derives from AActor and basically consists of named groups of light elements, which I want to be able to spawn and parameterize using the API. I can spawn, destroy, etc. the class, I also managed to write a function which empties a light group, i.e. deletes all respective light elements.

Extract from Actor.cpp:

  .def("empty_light_group", &cc::LightRig::EmptyGroup, (arg("light_group_name")))  // works fine

I can't quite set up the function which takes in the name of the desired light group and the desired light intensity.

Extract from Actor.cpp:

  .def("set_light_group_intensity", CALL_WITHOUT_GIL_2(cc::LightRig,SetGroupIntensity, std::string, float), (arg("light_group_name"), arg("intensity"))) // evokes a billion of boost errors

  .def("set_light_group_intensity", CONST_CALL_WITHOUT_GIL_2(cc::LightRig,SetGroupIntensity, std::string, float), (arg("light_group_name"), arg("intensity"))) // evokes a billion of boost errors, too

  .def("set_light_group_intensity", &cc::LightRig::SetGroupIntensity, (arg("light_group_name"), arg("intensity"))) // evokes a billion of boost errors as well

For clarity: of course I tried all three variants individually and not at once. ;) I receive C 2977 and C2955 errors, namely ""boost::mpl::list": Too many template arguments" and ""boost::mpl::list": use of class template requires template argument list".

I'd really appreciate help with this.

Best regards
Robert
