The simple skill acquisition tasks require discovering interaction between one object and the actions of the agent. These include: eating comestibles (MiniHack-Eat-v0), praying on an altar (MiniHack-Pray-v0), wearing armour (MiniHack-Wear-v0), and kicking locked doors (LockedDoors). In the regular versions of these tasks, the starting location of the objects and the agent is randomised, whereas in the fixed versions of these tasks (MiniHack-Eat-Fixed-v0, MiniHack-Pray-Fixed-v0, MiniHack-Wear-Fixed-v0 and MiniHack-LockedDoors-Fixed-v0) both are fixed. To add a slight complexity to the randomised version of these tasks, distractions in the form of a random object and a random monster are added to the third version of these tasks (MiniHack-Eat-Distract-v0, MiniHack-Pray-Distract-v0 and MiniHack-Wear-Distract-v0). These tasks can be used as building blocks for more advanced skill acquisition tasks.
