TWEEN_UPDATE

Description:

The Tween Update Event.

This event is dispatched by a Tween every time it updates any of the properties it is tweening.

A Tween that is changing 3 properties of a target will emit this event 3 times per change, once per property.

Note: This is a very high frequency event and may be dispatched multiple times, every single frame.

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

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