Syntax: Select all
random.choice(playerlib.getUseridList('#bot'))here is what i use in ES to get a random userid
here is what i tried in SP but don't work @@
doesn't print the index
Syntax: Select all
from events import Event
from players.entity import PlayerEntity
from filters.players import PlayerIter
@Event
def player_say(game_event):
new_t = random.choice(PlayerIter('ct'))
print(new_t)
Code: Select all
[SP] Caught an Exception:
Traceback (most recent call last):

File '../addons/source-python/plugins/test/test.py', line 26, in player_say
new_t = random.choice(PlayerIter('ct'))
File '../addons/source-python/Python3/random.py', line 256, in choice
return seq[i]
TypeError: 'PlayerIter' object does not support indexing
from wiki
Code: Select all
from filters.players import PlayerIter
# Usage
# for <variable or variables> in PlayerIter([str/list is_filters], [str/list not_filters], [str/list return_types]):
# Since "index" is the default return type, loop over all player indexes
for index in PlayerIter():
pass------------------- edit -------------------------------
after searching some more maybe i need to do this
Syntax: Select all
new_t = random.choice(list(PlayerIter('ct')))away from my comp now can't test >_<

Yes, casting the object to a list will works since it will iterate over the generator to build its sequence. Since we recently added __len__, I guess we could add indexing/slicing to the _IterObject class but this means it will iterate over the entire generator every time. A good practice will still remains to cast it as a sequence (list, tuple, set...) and store the result so you actually iterate once at this time even if you have ton of work to do on the filtered items.

I would also like to add that "indexing" has nothing to do with the return type. See this example:
Syntax: Select all
import random
print(random.choice(set(range(5))))
It's completely unrelated to Source.Python, but it will raise the same error.
Indexing just means accessing values of an iterable via indexes.

He means, when iterating over a PlayerIter object, player indexes are the default returned values unless otherwise specified on instantiation.

Yeah, but since he marked it as red I thought he was confused by "indexing" and "index".

Maybe, I guess xD

I think Ayuto is probably right. The error that you receive is because random.choice requires an indexible object, like a list. And indexing has nothing to do with player/entity indexes, which are what the default return types return for most of the classes that inherit from _IterObject.
