What are bot physics?
Bot physics controls how your accounts respond to environmental forces in the world.
With physics enabled
Bots behave like normal players. They're affected by gravity (they fall when blocks beneath them are removed), they interact with water (sliding, sinking), and they can be pushed by other entities.
With physics disabled
Bots ignore environmental forces. They float in place regardless of water or gravity, don't fall when supports are removed, and aren't pushed around by other entities.
When to disable physics
Disabling physics is useful when you want an account to hold an exact position - sitting on a specific block in an AFK pool, a fishing spot, or a farm where being pushed off by mobs or flowing water would break the setup. With physics off, the account stays put no matter what happens around it.
When to leave physics on
Leave physics enabled for normal play and for servers that check whether a player reacts to the world like a real client. Many anti-cheat systems expect players to fall, take knockback, and drift with water. Keeping physics on makes the account's behavior indistinguishable from a regular player.
