クラス: RotateControlStateMachine

定義: packages/board/src/camera/camera-mux/animation-and-lock/rotation-control-state-machine.ts:128

State machine controlling rotation input flow and animations.

Remarks

This state machine manages the lifecycle of rotation operations:

User input handling: Accepts or blocks user rotation gestures based on state
Animation control: Manages smooth rotate-to animations
Object tracking: Supports locking camera to follow objects with rotation

State transitions:

ACCEPTING_USER_INPUT → TRANSITION: Start animation (initateTransition)
ACCEPTING_USER_INPUT → LOCKED_ON_OBJECT: Lock to object (lockedOnObjectRotate...)
TRANSITION → ACCEPTING_USER_INPUT: User input interrupts animation
LOCKED_ON_OBJECT → ACCEPTING_USER_INPUT: Unlock (unlock event)

Helper methods simplify event dispatching without memorizing event names.

例

typescript

const stateMachine = createDefaultRotateControlStateMachine(cameraRig);

// User rotates - accepted in ACCEPTING_USER_INPUT state
const result = stateMachine.notifyRotateByInput(Math.PI / 4);

// Start animation - transitions to TRANSITION state
stateMachine.notifyRotateToAnimationInput(Math.PI);

// User input now blocked while animating

戻り値

void

Remarks

Forces state change to begin animation or transition sequence. Called when starting programmatic camera movements.
