Playing GLTF animation with start and end time

[goldenratio]

I have gltf animation model, duration is 2 minutes or so. I would need to categories those animations based on start and end, like in unity.
Do we have controls like .play(fromTime, endTime) ?

It's not built in, but you can create this function yourself.

function playAnimationClip(animation, fromTime, endTime, loop) {
  animation.position = fromTime
  let ticker = new PIXI.Ticker()
  ticker.add(() => {
    animation.position += ticker.deltaMS / 1000
    if (animation.position < endTime) {
      return
    }
    if (loop) {
      if (animation.position > endTime) {
        animation.position = fromTime
      }
    }
    else {
      animation.position = endTime
    }
  })
  ticker.start()
}
