Return type:

UniformVelocityCommand

__init__(*, resampling_time_range, debug_vis=False, entity_name, heading_command=False, heading_control_stiffness=1.0, rel_standing_envs=0.0, rel_heading_envs=1.0, rel_world_envs=0.0, rel_forward_envs=0.0, init_velocity_prob=0.0, ranges, viz=<factory>)
Parameters:

  • resampling_time_range (tuple[float, float])

  • debug_vis (bool)

  • entity_name (str)

  • heading_command (bool)

  • heading_control_stiffness (float)

  • rel_standing_envs (float)

  • rel_heading_envs (float)

  • rel_world_envs (float)

  • rel_forward_envs (float)

  • init_velocity_prob (float)

  • ranges (Ranges)

  • viz (VizCfg)

debug_vis: bool = False

Whether to enable debug visualization for this command term. When True, the command term’s _debug_vis_impl method is called each frame to render visual aids (e.g., velocity arrows, target markers).

resampling_time_range: tuple[float, float]

Time range in seconds for command resampling. When the timer expires, a new command is sampled and the timer is reset to a value uniformly drawn from [min, max]. Set both values equal for fixed-interval resampling.
