The Tween Start Event.

This event is dispatched by a Tween when it starts tweening its first property.

A Tween will only emit this event once, as it can only start once.

If a Tween has a delay set, this event will fire after that delay expires.

Listen to it from a Tween instance using Tween.on('start', listener), i.e.:

var tween = this.tweens.add({
    targets: image,
    x: 500,
    ease: 'Power1',
    duration: 3000
tween.on('start', listener);
