| <description> | ||
| This [SkeletonModifier3D] 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. | ||

| <members> | ||
| <member name="bone" type="int" setter="set_bone" getter="get_bone" default="0"> | ||
| The bone index of the [Skeleton3D] that the modification will operate on. | ||
| </member> | ||
| <member name="duration" type="float" setter="set_duration" getter="get_duration" default="0.0"> | ||
| The duration of the time-based interpolation. Interpolation is triggered at the following cases: | ||
| - When the target node is changed | ||
| - When an axis is flipped due to angle limitation | ||
| </member> | ||
| <member name="ease_type" type="int" setter="set_ease_type" getter="get_ease_type" enum="Tween.EaseType" default="0"> | ||
| The ease type of the time-based interpolation. See also [enum Tween.EaseType]. | ||
| </member> | ||
| <member name="forward_axis" type="int" setter="set_forward_axis" getter="get_forward_axis" enum="LookAtModifier3D.BoneAxis" default="4"> | ||
| The forward axis of the bone. This [SkeletonModifier3D] modifies the bone so that this axis points toward the [member target_node]. | ||
| </member> | ||
| <member name="primary_damp_threshold" type="float" setter="set_primary_damp_threshold" getter="get_primary_damp_threshold"> | ||
| The threshold to start damping for [member primary_limit_angle]. It provides non-linear(logarithmic) interpolation, let it feel more resistance the more it rotate to the edge limit. This is useful for simulating the limits of human motion. | ||
| If [code]1.0[/code], no damping is performed. If [code]0.0[/code], damping is performed always. | ||
| </member> | ||
| <member name="primary_limit_angle" type="float" setter="set_primary_limit_angle" getter="get_primary_limit_angle"> | ||
| The limit angle of the secondary rotation. | ||
| </member> | ||
| <member name="primary_rotation_axis" type="int" setter="set_primary_rotation_axis" getter="get_primary_rotation_axis" enum="Vector3.Axis" default="1"> | ||
| The axis of the first rotation. This [SkeletonModifier3D] works by compositing the rotation by Euler angles to prevent to rotate the [member forward_axis]. | ||
| </member> | ||
| <member name="secondary_damp_threshold" type="float" setter="set_secondary_damp_threshold" getter="get_secondary_damp_threshold"> | ||
| The threshold to start damping for [member secondary_limit_angle]. | ||
| </member> | ||
| <member name="secondary_limit_angle" type="float" setter="set_secondary_limit_angle" getter="get_secondary_limit_angle"> | ||
| The limit angle of the secondary rotation. | ||
| </member> | ||
| <member name="target_node" type="NodePath" setter="set_target_node" getter="get_target_node" default="NodePath("")"> | ||
| The [NodePath] to the node that is the target for the look at modification. This node is what the modification will rotate the bone to. | ||
| </member> | ||
| <member name="transition_type" type="int" setter="set_transition_type" getter="get_transition_type" enum="Tween.TransitionType" default="0"> | ||
| The transition type of the time-based interpolation. See also [enum Tween.TransitionType]. | ||
| </member> | ||
| <member name="use_angle_limitation" type="bool" setter="set_use_angle_limitation" getter="is_using_angle_limitation" default="false"> | ||
| If [code]true[/code], limits the degree of rotation. This helps prevent the character's neck from rotating 360 degrees. | ||
| [b]Note:[/b] As with [AnimationTree] blending, interpolation is provided that favors [method Skeleton3D.get_bone_rest]. This means that interpolation does not select the shortest path in some cases. | ||
| </member> | ||
| <member name="use_secondary_rotation" type="bool" setter="set_use_secondary_rotation" getter="is_using_secondary_rotation" default="true"> | ||
| If [code]true[/code], provides rotation by two axes. | ||
| </member> | ||
| </members> | ||
| <constants> | ||
| <constant name="BONE_AXIS_PLUS_X" value="0" enum="BoneAxis"> | ||
| Enumerated value for the +X axis. | ||

| Enumerated value for the -X axis. | ||
