                    targets: this.follower,
                    t:1,
                    ease: 'Sine.easeInOut',
                    duration: this.curve.getLength(),
                    onUpdate: function() {
                            this.player.x = this.follower.vec.x
                            this.player.y = this.follower.vec.y
                     },
                })
