Subject: Re: __index method not being
called??
Lua calls __index only when you're trying to read
from a field. When you're trying to write to a field (the case in your script)
Lua calls __newindex instead. __index=get, __newindex=set. Please check the
manual for more details (including Lua code for the field read and field write
behavior.
For your proxy tables you'll be better off
storing pointers to the structs in userdata, setting the __index metamethod to
a C function that retrieves the pointer and returns the valueof
the correct member and __newindex to a C function that retrieves the
pointer and writes to the correct struct member. You can even use the __gc
metamethod to free the struct.
