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

Hey, the project I'm currently working on requires me to store the players position in a text file, and then read the data back into the file to make a simulation of exactly what they did.

So far I can write the position in the file, and read it back out, however, when I read it out, I can only retrieve a string like "10,10,10" and need to split this into three floats, but nothing I'm doing seems to work.

Either this, or if I could get the x, y, z position of the player individually, that might be easier.

Thanks, Will.

Here's a code sample that shows how to parse the string "10,10,10" into a list of floating point numbers:

Code:

s = "10,10,10"



pos = [ float(x) for x in s.split(',') ]



print pos

Thank you so much! You're a life saver.

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):

Code:

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)
