Entity Documentation - minecraft:behavior.float_wander

Allows the mob to float around like the Ghast.

Float Wander Behavior Properties

Name	Default Value	Type	Description	Example Values
additional_collision_buffer	false	Boolean true/false	If true, the mob will have an additional buffer zone around it to avoid collisions with blocks when picking a position to wander to.	Happy Ghast: true
allow_navigating_through_liquids	false	Boolean true/false	If true allows the mob to navigate through liquids on its way to the target position.
float_duration	not set	Range of integers	Range of time in seconds the mob will float around before landing and choosing to do something else	Bat: [0.1,0.35], Ghast: [2,7]
float_wander_has_move_control	true	Boolean true/false	If true, the MoveControl flag will be added to the behavior which means that it can no longer be active at the same time as other behaviors with MoveControl.
must_reach	false	Boolean true/false	If true, the point has to be reachable to be a valid target	Ghast: true
navigate_around_surface	false	Boolean true/false	If true, will prioritize finding random positions in the vicinity of surfaces, i.e. blocks that are not Air or Liquid.	Happy Ghast: true
priority	not set	Integer number	As priority approaches 0, the priority is increased. The higher the priority, the sooner this behavior will be executed as a goal.	Ghast: 2, Happy Ghast: 7
random_reselect	false	Boolean true/false	If true, the mob will randomly pick a new point while moving to the previously selected one	Bat: true
surface_xz_dist	0	Integer number	The horizontal distance in blocks that the goal will check for a surface from a candidate position. Only valid when navigate_around_surface is true.	Happy Ghast: 16
surface_y_dist	0	Integer number	The vertical distance in blocks that the goal will check for a surface from a candidate position. Only valid when navigate_around_surface is true.	Happy Ghast: 16
use_home_position_restriction	true	Boolean true/false	If true, the mob will respect home position restrictions when choosing new target positions. If false, it will choose target position without considering home restrictions	Happy Ghast: true
xz_dist	10	Integer number	Distance in blocks on ground that the mob will look for a new spot to move to. Must be at least 1	Bat: 10
y_dist	7	Integer number	Distance in blocks that the mob will look up or down for a new spot to move to. Must be at least 1	Bat: 7
y_offset	0	Decimal number	Height in blocks to add to the selected target position	Bat: -2
