how to lua extend class bound by c++ (sol2) -


i have c++ class:

struct state {};

now, use sol2 (a lua binding library) in order create derived instance state: state_sleep, state_play, etc.

i'm trying create functions: on_enter, on_exe , on_exit

for example:

state_sleep = state.new() function state_sleep:on_enter     -- smt end

from issue 475:

you can achieve functionality having table defers unknown operations state's metatable. can creating table , setting __newindex , __index functions appropriately.

i'm sorry, tried lot of ways understand did mean, i'm failed.

is there know did mean, or how archive functionality ?
