Accessing properties of parent in subclass

Postby arawra » Wed May 16, 2018 7:04 am

SP keeps throwing errors whenever I try and access player.steamid in an object thats a subclass of players.entities.Player

Code: Select all

[SP] Caught an Exception:

It works fine for me in GunGame. We'd have to see some of your code to see why this might not be happening in your case.

Syntax: Select all

from players.entity import Player

class rpgPlayer(Player):

def __init__(self, index):
'''
newSteamid = self.steamid
if self.is_bot():
newSteamid += self.name
self.data = playerList[newSteamid]
'''

def setClass(rpgClass):
if rpgClass in CLASSES:
self.data.rpgClass = rpgClass

@Event('player_spawn')
def player_spawn(args):
player = rpgPlayer(index_from_userid(args['userid']))

You'll want to call the super() init method, otherwise certain things won't happen on initialization of the instance:

Syntax: Select all

class rpgPlayer(Player):

def __init__(self, index):
super().__init__(index)
# Other stuff


*Edit: also, you're missing the "self" argument in your other method.
*Edit2: also, instead of using index_from_userid yourself, you can always use the Player.from_userid classmethod:

Syntax: Select all

@Event('player_spawn')
def player_spawn(args):
player = rpgPlayer.from_userid(args['userid'])
