A [SkeletonModifier3D] for aligning bones along a [Path3D].
A [SkeletonModifier3D] for aligning bones along a [Path3D]. The smoothness of the fitting depends on the [member Curve3D.bake_interval]. If you want the [Path3D] to attach to a specific bone, it is recommended to place a [ModifierBoneTarget3D] before the [SplineIK3D] in the [SkeletonModifier3D] list (children of the [Skeleton3D]), and then place a [Path3D] as the [ModifierBoneTarget3D]'s child. Bone twist is determined based on the [method Curve3D.get_point_tilt]. If the root bone joint and the start point of the [Curve3D] are separated, it assumes that there is a linear line segment between them. This means that the vector pointing toward the start point of the [Curve3D] takes precedence over the shortest intersection point along the [Curve3D]. If the end bone joint exceeds the path length, it is bent as close as possible to the end point of the [Curve3D]. [b]Note:[/b] All the methods in this class take an [code]index[/code] parameter. This parameter specifies which setting list entry to return if the IK has multiple entries (e.g. [code]settings/<index>/root_bone_name[/code]).
Returns the node path of the [Path3D] which is describing the path.
Returns the tilt interpolation method used between the root bone and the start point of the [Curve3D] when they are apart. See also [method set_tilt_fade_in].
Returns the tilt interpolation method used between the end bone and the end point of the [Curve3D] when they are apart. See also [method set_tilt_fade_out].
Returns if the tilt property of the [Curve3D] affects the bone twist.
Sets the node path of the [Path3D] which is describing the path.
Sets if the tilt property of the [Curve3D] should affect the bone twist.
If [param size] is greater than [code]0[/code], the tilt is interpolated between [param size] start bones from the start point of the [Curve3D] when they are apart. If [param size] is equal [code]0[/code], the tilts between the root bone head and the start point of the [Curve3D] are unified with a tilt of the start point of the [Curve3D]. If [param size] is less than [code]0[/code], the tilts between the root bone and the start point of the [Curve3D] are [code]0.0[/code].
If [param size] is greater than [code]0[/code], the tilt is interpolated between [param size] end bones from the end point of the [Curve3D] when they are apart. If [param size] is equal [code]0[/code], the tilts between the end bone tail and the end point of the [Curve3D] are unified with a tilt of the end point of the [Curve3D]. If [param size] is less than [code]0[/code], the tilts between the end bone and the end point of the [Curve3D] are [code]0.0[/code].
