Bases: minedojo.tasks.meta.base.ExtraSpawnMetaTaskBase

Class for combat tasks. :type _sphinx_paramlinks_minedojo.tasks.meta.combat.CombatMeta.allow_mob_spawn: bool :param _sphinx_paramlinks_minedojo.tasks.meta.combat.CombatMeta.allow_mob_spawn: If True, allow mobs (animals and hostiles) to spawn.

Default: True.

Parameters

always_night¶ (bool) – If True, the world will always be at night. Default: False.
break_speed_multiplier¶ (float) – Controls the speed of breaking blocks. A value larger than 1.0 accelerates the breaking. Default: 1.0.
drawing_str¶ (Optional[str]) – Draws shapes (e.g. spheres, cuboids) in the minecraft world. Default: None.
event_level_control¶ (bool) – If True, the agent is able to perform high-level controls including place and equip. If False, then is keyboard-mouse level control. Default: True.
fast_reset¶ (bool) –
If True, reset using MC native command /kill, instead of waiting for re-generating new worlds. Default: True.

Warning

Side effects:

1. Changes to the world will not be reset. E.g., if the agent chops lots of trees then calling fast reset will not restore those trees.

2. If you specify agent starting health and food, these specs will only be respected at the first reset (i.e., generating a new world) but will not be respected in the following resets (i.e., reset using MC cmds). So be careful to use this wrapper if your usages require specific initial health/food.
