Overview

minecraft:behavior.float_wander is an entity component: it goes in the components object of a custom mob, or in one of its component groups. AI goal that makes the mob drift around in the air to random spots, like a ghast.

Fields

Field	Type	Default	Description
`xz_dist`	integer	`10`	How far sideways the next spot can be. Must be 1 or more.
`y_dist`	integer	`7`	How far up or down the next spot can be. Must be 1 or more.
`y_offset`	number	`0`	Blocks added to the height of the chosen spot.
`must_reach`	boolean	`false`	If true, the spot must be reachable to be picked.
`random_reselect`	boolean	`false`	If true, the mob may switch to a new spot before reaching the current one.
`use_home_position_restriction`	boolean	`true`	If true, spots are kept inside the mob's home area.
`float_duration`	FloatRange	`{"max":0,"min":0}`	Random range in seconds the mob drifts before doing something else.
`float_wander_has_move_control`	boolean	`true`	If true, this goal claims movement, so it cannot run with other goals that move the mob.
`surface_xz_dist`	integer	`8`	How far sideways to check for a surface near a spot. Only used with navigate_around_surface.
`surface_y_dist`	integer	`8`	How far up and down to check for a surface near a spot. Only used with navigate_around_surface.
`additional_collision_buffer`	boolean	`false`	If true, extra space is kept around the mob so it does not bump into blocks.
`navigate_around_surface`	boolean	`false`	If true, the mob prefers spots close to solid blocks instead of open air or liquid.
`allow_navigating_through_liquids`	boolean	`false`	If true, the mob may pass through liquids on the way.
`priority`	integer	`0`	Lower numbers run first: when two goals compete, the one with the smaller priority wins.Range: 0 to …
`control_flags`	Goal's control flags[]	none	Which body parts this goal takes over (move, look, jump), so goals using the same parts cannot run together.
