Hi,

whenever I do this (running CS: S):

@SayCommand(config["saycommand_weapons"])
def saycommand_weapons(playerinfo, command, teamonly):
    """
    Gets called whenever someone types the saycommand for the weapons menu in the chat.
    """
    
    # send the main menu
    menus[0].send(index_from_playerinfo(playerinfo))
    
    # block the message from being shown
    return CommandReturn.BLOCK

I get that exception:

Code: Select all

[SP] Caught an Exception: 
Traceback (most recent call last): 
  File '../addons/source-python/packages/source-python/commands/manager.py', line 148, in __call__ 
    return_value = callback(*args) 
  File '../addons/source-python/packages/source-python/commands/auth.py', line 63, in __call__ 
    return self.callback(*args) 
  File '../addons/source-python/plugins/simpledm/simpledm.py', line 307, in saycommand_weapons 
    menus[0].send(index_from_playerinfo(playerinfo)) 
 
IndexError: list index out of range

Why is that so? Because, I definitely have menus[0]:

The funny thing is, I actually open the weapons menu, and I can choose the weapons and receive them. The code itself works, it seems like the exception is coming out of nowhere. Sometimes it throws the exception and sometimes it doesn't... Can you help me? :)

I notice you don't close you menus on unload, but you do clear the list of menus. This is probably the cause of those errors. Close your menus on unload, either in your unload function or override the list's clear method to do so.

Makes sense, thanks.
