Notice than loading a file is INDEPENDENT # of its file format (Cerealizer or Pickle); Soya being able to determine the format # by itself. # Imports Soya and cerealizer. import sys, os, os.path, soya import cerealizer # Import the module that defines the RotatingBody class. Cerealizer or Pickle saves the # object data, but NOT the source or executable code of their class. # # Here, we use "execfile" since the file "basic-savingfile-cerealizer-1.py" is not a valid # Python module name, due to the "-" character in it. # However, you should normally use something like: # #import basic-savingfile-cerealizer-1 # # Wether we import "basic-savingfile-cerealizer-1.py" or "basic-savingfile-pickle-1.py" # has no importance, since the 'module part' (=before the "if __name__ == "__main__") is # the same in the two tutorial. execfile(os.path.join(os.path.dirname(sys.argv[0]), "basic-savingfile-cerealizer-1.py")) # Inits Soya and sets the data directory. soya.init() soya.path.append(os.path.join(os.path.dirname(sys.argv[0]), "data")) # Load the scene we have saved previously. "a_scene_with_a_rotating_body" is the filename # we have given to this scene. # The "World.load" method is similar to "Model.get", except that "load" ALWAYS returns a new # object read from the file, whereas "get" cache its result. scene = soya.World.load("a_scene_with_a_rotating_body") # Creates a camera. # # For technical reasons, camera are not saveable yet. This is not really a problem since the # camera is not really scene-dependent by rather configuration-dependent. # We thus add the camera AFTER loading the scene. camera = soya.Camera(scene) camera.z = 3.0 soya.set_root_widget(camera) soya.MainLoop(scene).main_loop()
