C++ Source:

  • Module: AnimGraphRuntime

  • File: AnimNode_Fabrik.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]

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

  • effector_rotation_source (BoneRotationSource): [Read-Write]

  • effector_target (BoneSocketTarget): [Read-Write] If EffectorTransformSpace is a bone, this is the bone to use. *

  • effector_transform (Transform): [Read-Write] Coordinates for target location of tip bone - if EffectorLocationSpace is bone, this is the offset from Target Bone to use as target location

  • effector_transform_space (BoneControlSpace): [Read-Write] Reference frame of Effector Transform.

  • enable_debug_draw (bool): [Read-Write] Toggle drawing of axes to debug joint rotation

  • 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

  • max_iterations (int32): [Read-Write] Maximum number of iterations allowed, to control performance.

  • precision (float): [Read-Write] Tolerance for final tip location delta from EffectorLocation

  • root_bone (BoneReference): [Read-Write] Name of the root bone

  • tip_bone (BoneReference): [Read-Write] Name of tip bone

property effector_transform: Transform

[Read-Write] Coordinates for target location of tip bone - if EffectorLocationSpace is bone, this is the offset from Target Bone to use as target location

Type:

(Transform)
