I am beginning to learn python and am creating a text based rpg. I am having a problem with a bit of the code. I have code that writes details to a save file including player stats etc.
This also saves the players current location which is a reference to an instance of a class. Not sure if this is needed, but this is the code for the location file:
CODE
class Locations:
def __init__ (self, x, y, north, south, east, west):
self.x = x
self.y = y
self.n = north
self.s = south
self.e = east
self.w = west
#Initialise the locations
a1_1 = Locations(1,1,0,0,1,0)
a1_3 = Locations(1,3,0,0,1,0)
a2_1 = Locations(2,1,0,1,1,1)
a2_2 = Locations(2,2,1,1,0,0)
a2_3 = Locations(2,3,1,0,1,1)
a3_1 = Locations(3,1,0,0,0,1)
a3_3 = Locations(3,3,0,0,0,1)
#Set the directional variables to point to the location a player
#would be in if they moved in that direction
a1_1.e = a2_1
a1_3.e = a2_3
a2_1.s = a2_2
a2_1.e = a3_1
a2_1.w = a1_1
a2_2.n = a2_1
a2_2.s = a2_3
a2_3.n = a2_2
a2_3.e = a3_3
a2_3.w = a1_3
a3_1.w = a2_1
a3_3.w = a2_3
The method I use to save and then to load is below:
CODE
save = raw_input("Do you want to save?")
if save == "y":
SaveString = str(Player1.n) + "\n" + str(Player1.l) + "\n" + str(Player1.hp) + "\n" + \
str(Player1.a) + "\n" + str(Player1.d) + "\n" + str(Player1.xp) + "\n" + \
str(Player1.maxhp) + "\n" + str(Player1.heal) + "\n" + \
str(Player1.dmin) + "\n" + str(Player1.dmax) + "\n" + str(Player1.g)
SaveGame = open("save.txt",'w')
SaveGame.write(SaveString)
SaveGame.close()
CODE
#Initialise the player with default stats
Player1 = Player('Default',1,30,30,10,2,2,0,1,3,100)
#The bit that loads a previously saved game - at the moment there can only be one saved game at a time
LoadGame = raw_input("Do you want to continue on a previously saved adventure?")
if LoadGame == "y":
z = open('save.txt','r')
x = z.readline()
Player1.n = x[:-1]
Player1.l = int(z.readline())
Player1.hp = int(z.readline())
Player1.maxhp = int(z.readline())
Player1.heal = int(z.readline())
Player1.a = int(z.readline())
Player1.d = int(z.readline())
Player1.xp = int(z.readline())
Player1.dmin = int(z.readline())
Player1.dmax = int(z.readline())
Player1.g = int(z.readline())
CurrentPosition
print "\nWelcome back " + Player1.n + ", good to see you again."
There is nothing currently to save the location as my problem is that when I load the info back into the variables it is loaded as a string and that won't point to the class instance I need it to.
I hope that makes sense?
What I need to be able to do is convert the string into something that points to the correct instance of the class Locations.
Can anyone help?
(Just incase it is needed I have zipped up the complete set of files I use to run the game.)
