Class: StateMachine

Defined in: src/components/anim/graph/StateMachine.ts:65

Lightweight, data-driven animation state machine.

Plug into an AnimatorComponent via animator.setStateMachine(fsm). On every onUpdate the FSM advances time, evaluates transitions, and may issue a crossFade on the underlying animator.

Why no visual graph editor: shipping a graph UX is a multi-year investment. A JSON/TS DSL covers 90% of use cases at <5% the cost; DCC tooling (Blender / Maya) is the right home for authoring.

Methods

sync()

sync(animator): void

Defined in: src/components/anim/graph/StateMachine.ts:91

Convenience: ensure the underlying animator is playing the right clip. Should be called once after attaching the FSM, or any time external code wants to force a sync.

Parameters

animator

AnimatorComponent

Returns

void

---

evaluate()

evaluate(animator, dt): void

Defined in: src/components/anim/graph/StateMachine.ts:96

Called by AnimatorComponent.onUpdate every frame.

Parameters

animator

AnimatorComponent

dt

number

Returns

void
