So, here's another newbie question:
I'm working on an app that will have several different types of
scenes/UIs, which will be switched back and forth from.
I subclass each type of scene (sort of like a level in the tutorials..)
from the "Scene" class (attached below). However, I find that actually
deleting them when I'm done with them is problematic. They don't seem to
go away like normal python objects, but rather hang around in memory
causing a leak.
Is there something specific I need to do in the destructor to delete
Worlds? Should I be iterating through all the children and deleting them
individually?
Thanks for any help,
justin
class Scene( World ):
"""World that accepts commands and has a built-in idler, which
will return another scene when done idling, or None if the sequence
is finished.
"""
def __init__( self ):
self.__idler = None
World.__init__( self )
self.__camera = soya.Camera(self)
self.__group = widget.Group()
self.__group.add( self.camera )
self.__group.add( widget.FPSLabel() )
soya.set_root_widget( self.__group )
def idle( self ):
soya.set_root_widget( self.__group )
self.__idler = Idler(self)
return self.__idler.idle()
def screenshot( self ):
import time
import os
time_str = time.strftime( "%Y%m%d_%H%M" )
file = "%s_%s.jpg" % ( self.__class__.__name__, time_str )
ss = os.path.join( "results", file )
soya.screenshot().resize( _SCREENSHOT_SIZE ).save(ss)
def stop( self, val ):
if self.__idler is not None:
self.__idler.stop( val )
self.__idler = None
camera = property( lambda self: self.__camera )
group = property( lambda self: self.__group )
