Hello,
I’m trying to use OOLUA for a project but I’m afraid I’m kind of stuck.
Essentially I have C++ objects that are created in C++. I want to be able to
pass them to lua for manipulation. However I don’t want the lua script to ever
have references to destroyed objects. The objects can be destroyed in lua or
from within c++. Is there any way to go through all the lua state and set
references that reference a destroyed object to nil? Or to recognize a passed
reference is invalid and throw an error on the LUA side? (That way the C++
never tries to use an invalid poinetr)
My current approach is to create all the objects in lua and store them in
arrays. When I want to destroy the object from C++ I remove the the object from
the array in lua. Then when all the references are eventually destroyed the lua
code automatically cleans up the object.
Unfortunately this has a lot of down sides:
* Relying a lot on the lua garbage collector
* have to create/destroy everything using lua
I might be able to work around some of the down sides, but at the very least I
really want to create the objects in C++. So I want to be able to have some
code that looks like:
object * MakeObject() {
return new object(stuff);
}
and have the object* be memory tracked by LUA. Or if there’s a way to avoid
this hacky approach altogether that would be appreciated.
Thanks,
Anthony
