Splitting a string into 3 ints, or getting x,y,z position

[Frank Verberne]

In the future, you might want to look at using the cPickle module for storing objects (lists, numbers, dictionaries, pretty much anything) in a text file and retrieving the same objects later on.

Here is an example where the rotation of the mainview of Vizard is stored in a text file (by pressing the d-key) and read from that file (by pressing the r-key):

import viz
import cPickle

viz.go()

def writeInfo():
	orientation = viz.MainView.getEuler()
	file_rot = open('MainView_rot.txt', 'w+')
	cPickle.dump(orientation, file_rot)
	file_rot.flush()
	file_rot.close()
	print 'Succesfully pickled:', orientation

def readInfo():
	try:
		file_rot = open('MainView_rot.txt', 'r')
		orientation = cPickle.load(file_rot)
		file_rot.flush()
		file_rot.close()
		print 'Succesfully unpickled:', orientation
	except IOError:
		print 'Could not read file!'
	
def onKeyDown(key):
	if key in 'dD':
		writeInfo()
	elif key in 'rR':
		readInfo()
	else:
		pass
	
viz.callback(viz.KEYDOWN_EVENT, onKeyDown)
