Why base resources always is 0

[hsushuai]

I am trying to use the map maps/8x8/basesWorkers8x8.xml, why does obs always get 0 resources for the base? How can I know how many resources the player has?

env = MicroRTSGridModeVecEnv(
    num_selfplay_envs=0,
    num_bot_envs=1,
    max_steps=2000,
    render_theme=2,
    ai2s=[microrts_ai.coacAI for _ in range(1)],
    map_paths=[map_name],
    reward_weight=np.array([10.0, 1.0, 1.0, 0.2, 1.0, 4.0]),
    autobuild=False,
)
env.metadata["video.frames_per_second"] = args.video_fps

name_prefix = map_name.split("maps/")[-1].split(".xml")[0].replace("/", "-")
env = VecVideoRecorder(
    env,
    "videos",
    record_video_trigger=lambda x: True,
    video_length=args.video_length,
    name_prefix=name_prefix,
)

obs = env.reset()
