Tweening is the process of interpolating between two values over time to create smooth animations. In Phaser, tweens are used to animate properties of game objects, such as position, scale, rotation, alpha, and more. you can even recreate physics simulation with tween. You can create a tween using this.tweens.add() method. Here’s the basic example of tween: var tween = this.tweens.add({ targets: gameObject, // The game object to tween duration: duration, // Duration of the tween in milliseconds props: { property: value }, // Properties to tween ease: 'type', // Type of easing to use ('Linear', 'Cubic', 'Elastic', etc.
