Class FBXConstraintBehavior

constructor

• new FBXConstraintBehavior(
      constraint: FBXConstraintData,
      _options: FBXConstraintBehaviorOptions,
  ): FBXConstraintBehavior

  Creates the behavior.

  Parameters

  • constraint: FBXConstraintData

    Constraint data extracted from the file

  • _options: FBXConstraintBehaviorOptions

    Resolved targets and scene information

  Returns FBXConstraintBehavior

attachedNode

Readonlyconstraint

enabled

Readonlyname

attach

• attach(target: TransformNode): void

  Registers the behavior with the scene's solver, takes the node's current transform as the unconstrained value and solves the constraint once.

  Parameters

  • target: TransformNode

    Node to constrain

  Returns void

captureBase

• captureBase(): void

  Takes the node's current transform as the unconstrained value the next solve blends from. The solver calls this after the scene's animations ran; call it yourself after writing a transform by hand.

  Returns void

dependencyNodes

• dependencyNodes(): Nullable<Node>[]

  Nodes whose world transform the solve reads: the targets, the up node and the constrained node's parent.

  Returns Nullable<Node>[]

  The nodes, used by the solver to order constraints

detach

• detach(): void

  Unregisters the behavior; the node keeps its last solved transform.

  Returns void

evaluate

• evaluate(): void

  Solves the constraint from the captured unconstrained transform and writes the node's local transform. Blends are relative to the value captured by captureBase, not to whatever the node holds now.

  Returns void

init

• init(): void

  Nothing to initialize

  Returns void

restoreBase

• restoreBase(): void

  Writes the unconstrained transform back to the node. The solver calls this before the scene's animations run, so a node nothing animates keeps its unconstrained value between frames instead of the solved one.

  Returns void
