Re: Member pointers in 0.8.1

Greetings,

This might be a no can do but you wizards out there might have an hocus
pocus workarounds...

Let say the basic function is define like this:

.def("GetObject", (Object*(Manager::*)(Name &)) &Manager::GetObjectByName)

All good, the Manger return an Object, but many classes derived from Object
in my C++ and my Luabind Modules follow the same structure. In c++ you can
statically cast to the desired type... Is there a way to static cast a
Luabind return value within a Lua script?

Something like:

local l_camera = (Camera*) Manager:GetObject(Name("Camera"));


This would work But it is not really sexy...

.def("GetActor", (Actor*(Manager::*)(Name &)) &Manager::GetObjectByName)
.def("GetCamera", (Camera*(Manager::*)(Name &)) &Manager::GetObjectByName)

thx
