Spawning problem

Phaser 3
1

Hi, I have this class constructor and I’m trying to spawn enemies onto my canvas however they are not showing up? There is not error either… Help would be greatly appreciated

class Enemy extends Phaser.Physics.Arcade.Sprite {
constructor(scene, game, tank, player, x, y, bullets){
super(scene);

                var x = Phaser.Math.RND.between(0, 800);
                var y = Phaser.Math.RND.between(0, 600);

                this.game = game;
                //scene.physics.add.existing(this)
                                   
                this.health = 3;
                this.player = player;
                this.bullets = bullets;
                this.fireRate = 1000;
                this.nextFire = 0;
                this.alive = true;

                this.turret = new Phaser.Physics.Arcade.Sprite(scene, 100, 100, 'enemy', 'tank1');
                this.tank = new Phaser.Physics.Arcade.Sprite(scene, 100, 100, 'enemy', 'turret');
                this.turret.setOrigin(0.3, 0.5);
                this.tank.setOrigin(0.5, 0.5);
                /*this.tank.body.immovable = false;
                this.tank.body.collideWorldBounds = true;
                this.tank.body.bounce.setTo(1, 1);*/
            }
            
            update(time, delta) {

                this.turret.x = this.tank.x;
                this.turret.y = this.tank.y;

            }
        }

        myguy = this.physics.add.group({

            classType: Enemy,
            maxSize: 20,
            runChildUpdate: true
        });

        myguyy = myguy.get().setActive(true).setVisible(true);

you have a group but have not created nothing in it. try
myguy.create() link
