Play without human, watch two AIs or Bots play against each other (with rendering)

[asyschikov]

Just trying to make to get any combination of players work without human type of player (keyboard):

python -m gfootball.play_game --action_set=full --players "lazy:left_players=1;bot:right_players=1"
python -m gfootball.play_game --action_set=full --players "bot:left_players=1;bot:right_players=1"
python -m gfootball.play_game --action_set=full --players "lazy:left_players=1;lazy:right_players=1"
python -m gfootball.play_game --players "lazy:left_players=1;lazy:right_players=1"

The game just hangs and never renders a single frame (Mac). Any suggestions? Thanks!

@asyschikov The proposed commands don't work on my Mac too. I'll try to look into it.

add few lines code into gfootball/env/players/agent.py as below will solve this problem. I am not sure this is the best solution.

"""Agent player controlled by the training policy and using step/reset API."""
from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
 
import copy
 
from gfootball.env import player_base
import pygame
 
class Player(player_base.PlayerBase):
 
  def __init__(self, player_config, env_config):
    player_base.PlayerBase.__init__(self, player_config)
    assert player_config['player_agent'] == 0, 'Only one \'agent\' player allowed'
    self._action = None
    self._init_done = False
    pygame.init()
 
  def set_action(self, action):
    self._action = action
 
  def take_action(self, observations):
    if not self._init_done:
      self._init_done = True
      pygame.display.set_mode((1, 1), pygame.NOFRAME)
    pygame.event.get()
    return copy.deepcopy(self._action)
