python - 谷歌 RL 足球模拟器的录制屏幕

问题描述

我正在尝试使用基于openAI-Gym的谷歌足球模拟器模拟足球比赛时录制屏幕。我目前的代码是：

import gfootball.env as football_env

env = football_env.create_environment(env_name='11_vs_11_stochastic', render=True)
env.reset()
done = False
while not done:
    action = env.action_space.sample()
    observation, reward, done, info = env.step(action)

它显示了游戏，但我不知道如何记录它。任何帮助，将不胜感激。

解决方案

如果其他人想知道，这里有一个很好的文档。您需要做的就是添加write_video = True到环境配置中。我的代码现在看起来像这样并且可以工作：

from __future__ import absolute_import
from __future__ import division
from __future__ import print_function

from absl import app
from absl import flags
from absl import logging


from gfootball.env import config
from gfootball.env import football_env

FLAGS = flags.FLAGS

flags.DEFINE_string('players', 'keyboard:left_players=1',
                    'Semicolon separated list of players, single keyboard '
                    'player on the left by default')
flags.DEFINE_string('level', '', 'Level to play')
flags.DEFINE_enum('action_set', 'default', ['default', 'full'], 'Action set')
flags.DEFINE_bool('real_time', True,
                  'If true, environment will slow down so humans can play.')
flags.DEFINE_bool('render', True, 'Whether to do game rendering.')


def main(_):
  players = FLAGS.players.split(';') if FLAGS.players else ''
  assert not (any(['agent' in player for player in players])
             ), ('Player type \'agent\' can not be used with play_game.')
  cfg = config.Config({
      'action_set': FLAGS.action_set,
      'dump_full_episodes': True,
      'players': players,
      'real_time': FLAGS.real_time,
      'dump_full_episodes': True,
      'tracesdir': 'path/to/dir',
      'write_video': True,
      'render': True
  })
  if FLAGS.level:
    cfg['level'] = FLAGS.level
  env = football_env.FootballEnv(cfg)
  if FLAGS.render:
    env.render()
  env.reset()
  try:
    while True:
      _, _, done, _ = env.step([])
      if done:
        env.reset()
  except KeyboardInterrupt:
    logging.warning('Game stopped, writing dump...')
    env.write_dump('shutdown')
    exit(1)


if __name__ == '__main__':
  app.run(main)

请注意，我刚刚在官方 github repo 的文件中添加了一些配置。
