bullet class phaser 3 fix

[jasper1990]

I'm developing a rail shooter and I'm trying to copy the bullet class from phaser 3 example here : https://labs.phaser.io/view.html?src=src\games\defenda\test.js&v=3.2.1.

I'm having issues with no bullets appearing *when I press spacebar*, there appears to be no errors in the console either. I'm not entirely sure how groups work, but could someone explain to me? I'm using phaser 3.2.1

Hello @jasper1990! Can you please post the related code, which you believe is the problem?

[jasper1990]

I added a zip file, but specifically I get an issue with the following :

    function create (){

        var Bullet = Phaser.Class({
            Extends: Phaser.GameObjects.Image,

            initialize:

            function Bullet(scene)
            {
                Phaser.GameObjects.Image.call(this, scene, 0, 0, 'bullet');

                this.speed = 0;
                this.born  = 0;
            },

            fire: function (argplayer)
            {
                this.setPosition(argplayer.x, argplayer.y);

                this.speed = 20;

                this.born = 0;
            },

            update: function (time, delta)
            {
                this.y += this.speed * delta;

                this.born += delta;

                if (this.born > 1000)
                {
                    this.setActive(false);
                    this.setVisible(false);
                }
            }
        });

        player = new Player(this, 100, 400);

        this.anims.create({
        key: 'middle',
        frames: this.anims.generateFrameNumbers(PLAYER_LABEL, { start: 0, end: 2 }),
        frameRate: 10,
        repeat: -1
        });

        this.anims.create({
        key: 'left',
        frames: this.anims.generateFrameNumbers(PLAYER_LABEL, { start: 3, end: 5 }),
        frameRate: 10,
        repeat: -1
        });

        this.anims.create({
        key: 'right',
        frames: this.anims.generateFrameNumbers(PLAYER_LABEL, { start: 6, end: 8 }),
        frameRate: 10,
        repeat: -1
        });

        this.bullets = this.add.group({ classType: Bullet, runChildUpdate: true });
        this.lastFired = 0;

        cursor = this.input.keyboard.createCursorKeys();

        KeyZ = this.input.keyboard.addKey(Phaser.Input.Keyboard.KeyCodes.Z);
        KeyX = this.input.keyboard.addKey(Phaser.Input.Keyboard.KeyCodes.X);
        KeyC = this.input.keyboard.addKey(Phaser.Input.Keyboard.KeyCodes.C);
    }

    function update (time, delta){
        if (cursor.right.isDown)
        {
            player.moveRight();
            if(player.checkBoundary(256,512, 0))
            {
                player.moveLeft();
            }
        }
        else if(cursor.left.isDown)
        {
            player.moveLeft();
            if(player.checkBoundary(256,512, 0))
            {
                player.moveRight();
            }
        }
        else if(cursor.up.isDown)
        {
            player.moveUp();
            if(player.checkBoundary(256,512, 0))
            {
                player.moveDown();
            }
        }
        else if (cursor.down.isDown)
        {
            player.moveDown();
            if(player.checkBoundary(256,512, 0))
            {
                player.moveUp();
            }
        }

        if(KeyZ.isDown)
        {
            player.aimLeft();
        }

        if(KeyX.isDown)
        {
            player.aimMiddle();
        }

        if(KeyC.isDown)
        {
            player.aimRight();
        }

        if (cursor.space.isDown && time > this.lastFired)
        {
            var bullet = this.bullets.get();
            bullet.setActive(true);
            bullet.setVisible(true);

            if (bullet)
            {
                bullet.fire(player);

                this.lastFired = time + 100;
            }
        }

        player.renderAim();
    }

@jasper1990 cant see the problem right now. break down the problem a bit, put some console.log() inside the functions and check whether the code ever gets there. check the console for that. and if there is an error in the console, report it.
