Anim Node Spline IK

C++ Source:

• Module: AnimGraphRuntime

• File: AnimNode_SplineIK.h

Editor Properties: (see get_editor_property/set_editor_property)

• alpha (float): [Read-Write] Current strength of the skeletal control

• alpha_bool_blend (InputAlphaBoolBlend): [Read-Write]

• alpha_bool_enabled (bool): [Read-Write]

• alpha_curve_name (Name): [Read-Write]

• alpha_input_type (AnimAlphaInputType): [Read-Write]

• alpha_scale_bias (InputScaleBias): [Read-Write]

• alpha_scale_bias_clamp (InputScaleBiasClamp): [Read-Write]

• auto_calculate_spline (bool): [Read-Write] The number of points in the spline if we are specifying it directly

• bone_axis (SplineBoneAxis): [Read-Write] Axis of the controlled bone (ie the direction of the spline) to use as the direction for the curve.

• component_pose (ComponentSpacePoseLink): [Read-Write] Input link

• control_points (Array[Transform]): [Read-Write] Transforms applied to spline points *

• end_bone (BoneReference): [Read-Write] Name of bone at the end of the spline chain. Bones after this will not be altered by the controller.

• lod_threshold (int32): [Read-Write] * Max LOD that this node is allowed to run * For example if you have LODThreshold to be 2, it will run until LOD 2 (based on 0 index) * when the component LOD becomes 3, it will stop update/evaluate * currently transition would be issue and that has to be re-visited

• offset (float): [Read-Write] The distance along the spline from the start from which bones are constrained

• point_count (int32): [Read-Write] The number of points in the spline if we are not auto-calculating

• roll (float): [Read-Write] Overall roll of the spline, applied on top of other rotations along the direction of the spline

• start_bone (BoneReference): [Read-Write] Name of root bone from which the spline extends *

• stretch (float): [Read-Write] The maximum stretch allowed when fitting bones to the spline. 0.0 means bones do not stretch their length, 1.0 means bones stretch to the length of the spline

• twist_blend (AlphaBlend): [Read-Write] How to interpolate twist along the length of the spline

• twist_end (float): [Read-Write] The twist of the end bone. Twist is interpolated along the spline according to Twist Blend.

• twist_start (float): [Read-Write] The twist of the start bone. Twist is interpolated along the spline according to Twist Blend.
