Pokémon Behaviour
A Pokémon's AI behaviour is configurable from their species JSON. This is used control whether it can walk, swim, or fly as well as the speed it moves while doing each of those, whether or not it can fall asleep, and various other things.
The default is a land-moving AI that moves at a brisk pace, cannot breathe underwater, and does not sleep.

A light level or level range, between 0 and 15, which represents the light levels in which the Pokémon is able to sleep.

|
| depth
|
The depth of the sleep. This is a classification on what things can interrupt the sleep and make the Pokémon wake up. If you set it to "normal" then it will wake up when a non-sneaking player is within 16 blocks of the Pokémon. Another option is "comatose", and this causes the Pokémon to sleep through pretty much anything. You can add new sleep depths using the SleepDepth API.
|
| willSleepOnBed
|
A true/false value. If true, the Pokémon will try to sleep on top of the player's bed when they hop into it, much like cats.
