Lay Egg Behavior Properties

Name	Default Value	Type	Description	Example Values
allow_laying_from_below	false	Boolean true/false	Allows the mob to lay its eggs from below the target if it can't get there. This is useful if the target block is water with air above, since mobs may not be able to get to the air block above water.	Frog: true
egg_type	minecraft:turtle_egg	String	Block type for the egg to lay. If this is a turtle egg, the number of eggs in the block is randomly set.	Frog: "minecraft:frog_spawn"
goal_radius	0.5	Decimal number	Distance in blocks within the mob considers it has reached the goal. This is the "wiggle room" to stop the AI from bouncing back and forth trying to reach a specific spot	Frog: 1.7, Turtle: 1.5
lay_egg_sound	lay_egg	String	Name of the sound event played when laying the egg. Defaults to lay_egg, which is used for Turtles.	Frog: "lay_spawn"
lay_seconds	10	Decimal number	Duration of the laying egg process in seconds.	Frog: 2
on_lay	not set	Minecraft Event Trigger	Event to run when this mob lays the egg.	Frog: {"event":"laid_egg","target":"self"}, Turtle: {"event":"minecraft:laid_egg","target":"self"}
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.	Frog: 2, Turtle: 1
search_height	1	Integer number	Height in blocks the mob will look for a target block to move towards	Frog: 3, Turtle: 4
search_range	0	Integer number	The distance in blocks it will look for a target block to move towards	Frog: 10, Turtle: 16
speed_multiplier	1	Decimal number	Movement speed multiplier of the mob when using this AI Goal	Frog: 1
target_blocks	[ minecraft:sand ]	Array of strings	Blocks that the mob can lay its eggs on top of.	Frog: ["minecraft:water"]
target_materials_above_block	[ Air ]	Array of strings	Types of materials that can exist above the target block. Valid types are Air, Water, and Lava.	Frog: ["Air"]
