Hi folks!
The problem is the following:
I use Python 2.1 embedded in a C++ game engine. Some of the engines
complexer objects (AI, game logic, etc.) use python classes that act as
an extension of those "parent" C++-classes.
The python classes are currently loaded on demand by their "parent"
C++-instances, say if an enemy gets activated and starts running. I do
that by:
1.) reading the needed python script (dedicated to that enemy class)
into a string and then
2) calling 'Py_CompileStri ng()' followed by
3) 'PyEval_EvalCod e()'
Then I have access to all class(es) defined in the python script
implementing all the needed methods for my enemy.
It looks a bit tedious than just calling e.g. 'PyRun_SimpleFi le()', but
I thought, that PyEval_EvalCode () could provide me with means to force
a local and global namespace on the interpreted code.
Problem and Question:
To get rid of ALL code/class definitions/etc. defined when I loaded and
interpreted the enemy's python script, I want the python interpreter to
force a namespace or module context on everything associated with my
enemy, so I can be sure I cleaned up everything that is related to the
previous loading operation. I tried to use a new module (e.g. calling
'PyImport_AddMo dule') as my local namespace, but the script couldn't
find any built-in functions or even other classes defined in the very
same script file anymore when I did that.
Any idea how to do that properly?
Cheers!
