HI, I have a question about lua again. Can I modify a C++ class's properties in lua script? for example: /////////////C code//////////////// class A { A(){}; ~A(){}; public: int a; int b; } void main() { A a = A(); lua_state L = lua_open(); luadofile(L, "modifyA.lua"); lua_close(L); } ////////////Lua Code//////////// function modify() --do modify to A end //////////////////////////////// Thank you

You can modify A through an accessor that you register with Lua.

There are several examples illustrating this, but it works for small classes. For large projects it is recommended that you use some glue code generator, like tolua++ or luabind. They take a header file and generate required code to pass your class and modify it in lua scripts.
