I want to be able to do the following: Pass a container to a lua function Return the container to the c++ calling code Pass the container to another lua function Add to and remove from the container in lua Iterate over the container in lua Edit a particular element from the container in lua So far I've been trying to achieve this through combinations of exposing or wrapping stl containers, using return_stl_iterator, using luabind::newTable to create a table from a container. Can anyone reccomend a way to achieve the above requirements - or advise if I'm attacking this in the wrong way? If I can provide more info please let me know, Many thanks in advance,

Hello,

Having looked at several different ways of achieving what I want, the standout option by far (provided I can get this to work) is to be able to use at least
push_back, push_front, pop_back, pop_front, back, front and at where applicable from the stl containers in LUA. I don't particularly need iterators as I can get by with the above functions.

Push & pop are simple enough to expose and use, but I'm struggling with back.

Heres my code to expose vector<T>::back :



and here is the attempt to call in lua:



(BehaviourManager is correctly defined as a global, getPath definitely returns a std::vector<Vector2>)

the (custom) lua error is :

[LUA] Error : ..\Data\media\scripting\lua\testIdle.lua:43: attempt to call method 'back' (a nil value) source : @..\Data\media\scripting\lua\testIdle.lua what : Lua line : 8

I expect that its something to do with the return type of back - ie that its a reference, or that there are 2 overloads of back (returning reference or const reference) but I don't see why thats a problem?

Is anyone kind hearted enough to help? This is really holding me up so any suggestions would be very welcome :)

Ugh - please ignore I was returning a std::list from getPath - what a gigantic waste of time!
