AnimationPlayer

interface

Provides programmatic control of a reusable animation sequence, built using the build() method of AnimationBuilder. The build() method returns a factory, whose create() method instantiates and initializes this interface.

interface AnimationPlayer {
  parentPlayer: AnimationPlayer | null
  totalTime: number
  beforeDestroy?: () => any
  onDone(fn: () => void): void
  onStart(fn: () => void): void
  onDestroy(fn: () => void): void
  init(): void
  hasStarted(): boolean
  play(): void
  pause(): void
  restart(): void
  finish(): void
  destroy(): void
  reset(): void
  setPosition(position: any): void
  getPosition(): number
}
