Hi Everyone,
I am a beginner on cross language development. My problem at hand is to
build a python interface for a C++ application built on top of a 3D
game engine. The purpose of this python interface is providing a
convenient scripting toolkit for the application. One example is that
a user can write a python script like:
player = Player()
game.loadPlayer(player)
player.moveTo(location)
To configure the game environment.
I am trying to figure out how to make this happen. I only have the
vague idea that this concerns embedding/extending python with C++, but
after reading Python Doc, SWIG, BOOST.Python, I am still not sure how
to architecture it.
Since the main program is still going to be the C++ application, I
guess we need to embedding the python scripts in the C++ code. So at
initialization stage, the python script needs to be loaded into the C++
code. And this code can be simple, like
player = Player()
game.loadPlayer(player)
But for this to work, the python code needs to know the Player class,
is it right? Does that mean I need to build a python wrapper class for
Player and "import Player" in the python code? But because this
application is built on top of a game engine, Player class inherits
many classes from there, I cannot possibly wrapping them all, right?
Also, some global objects are probably needed in this code of adding
players, how can the python code access them?
I know I probably don't have a grasp of basics here, please kindly
enlighten me!
Btw, if you can point me to any source code of non-trivial projects
utilizing SWIG/Boost.Python, that would be very helpful. I found the
examples on the tutorials are far too simple.
Thank you very much,
Qun
