Hi,
Thanks for your answers.
But, is their an easy way to create a local variable from C++ to Lua ?
I just found how to inject global variables with the setglobal function.
For exemple :
local self = theRefFromC++
And, I don't find how to call a specific function describes in a Lua Script
For example :
MyActor = {}
MyActor:Manage(Object)
end
How can I call this function and how can I be sure that there aren't any collisions with
another actor with the same script ?
Thanks,
Tim
