	<brief_description>
		A modification that rotates a [Bone2D] node to look at a target.
	</brief_description>
	<description>
		This [SkeletonModification2D] rotates a bone to look a target. This is extremely helpful for moving character's head to look at the player, rotating a turret to look at a target, or any other case where you want to make a bone rotate towards something quickly and easily.

	<methods>
		<method name="get_additional_rotation" qualifiers="const">
			<return type="float" />
			<description>
				Returns the amount of additional rotation that is applied after the LookAt modification executes.
			</description>
		</method>
		<method name="get_constraint_angle_invert" qualifiers="const">
			<return type="bool" />
			<description>
				Returns whether the constraints to this modification are inverted or not.
			</description>
		</method>
		<method name="get_constraint_angle_max" qualifiers="const">
			<return type="float" />
			<description>
				Returns the constraint's maximum allowed angle.
			</description>
		</method>
		<method name="get_constraint_angle_min" qualifiers="const">
			<return type="float" />
			<description>
				Returns the constraint's minimum allowed angle.
			</description>
		</method>
		<method name="get_enable_constraint" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the LookAt modification is using constraints.
			</description>
		</method>
		<method name="set_additional_rotation">
			<return type="void" />
			<argument index="0" name="rotation" type="float" />
			<description>
				Sets the amount of additional rotation that is to be applied after executing the modification. This allows for offsetting the results by the inputted rotation amount.
			</description>
		</method>
		<method name="set_constraint_angle_invert">
			<return type="void" />
			<argument index="0" name="invert" type="bool" />
			<description>
				When [code]true[/code], the modification will use an inverted joint constraint.
				An inverted joint constraint only constraints the [Bone2D] to the angles [i]outside of[/i] the inputted minimum and maximum angles. For this reason, it is referred to as an inverted joint constraint, as it constraints the joint to the outside of the inputted values.
			</description>
		</method>
		<method name="set_constraint_angle_max">
			<return type="void" />
			<argument index="0" name="angle_max" type="float" />
			<description>
				Sets the constraint's maximum allowed angle.
			</description>
		</method>
		<method name="set_constraint_angle_min">
			<return type="void" />
			<argument index="0" name="angle_min" type="float" />
			<description>
				Sets the constraint's minimum allowed angle.
			</description>
		</method>
		<method name="set_enable_constraint">
			<return type="void" />
			<argument index="0" name="enable_constraint" type="bool" />
			<description>
				Sets whether this modification will use constraints or not. When [code]true[/code], constraints will be applied when solving the LookAt modification.
