Error running animation

Phaser 3

I do not understand what is happening, I always did it that way and it always worked, now I was giving this error, I can not see the error in my script, this is the error:

Uncaught TypeError: Cannot read property ‘play’ of undefined

You have to redeclare player and cursors in the update function like this
var player = this.player;
var cursors = this.cursors;

did not work, now changed the error, I’m not understanding, I’m doing the same as the firstgame, always did it this way and never gave these errors

Uncaught TypeError: Cannot read property ‘anims’ of undefined

Do you use phaser 3 version?If yes you will use this code

    var player = null;
    var cursors = null;
    var score = 0;
    var scoreText = null;
    

    function preload()
    {
        this.load.image('sky', 'src/games/firstgame/assets/sky.png');
        this.load.image('ground', 'src/games/firstgame/assets/platform.png');
        this.load.image('star', 'src/games/firstgame/assets/star.png');
        this.load.image('bomb', 'src/games/firstgame/assets/bomb.png');
        this.load.spritesheet('dude', 'src/games/firstgame/assets/dude.png', { frameWidth: 32, frameHeight: 48 });
    }

    function create()
    {
        this.add.image(400, 300, 'sky');

        var platforms = this.physics.add.staticGroup();

        platforms.create(400, 568, 'ground').setScale(2).refreshBody();

        platforms.create(600, 400, 'ground');
        platforms.create(50, 250, 'ground');
        platforms.create(750, 220, 'ground');

        var player = this.physics.add.sprite(100, 450, 'dude');

        player.setBounce(0.2);
        player.setCollideWorldBounds(true);

        this.anims.create({
            key: 'left',
            frames: this.anims.generateFrameNumbers('dude', { start: 0, end: 3 }),
            frameRate: 10,
            repeat: -1
        });

        this.anims.create({
            key: 'turn',
            frames: [ { key: 'dude', frame: 4 } ],
            frameRate: 20
        });

        this.anims.create({
            key: 'right',
            frames: this.anims.generateFrameNumbers('dude', { start: 5, end: 8 }),
            frameRate: 10,
            repeat: -1
        });

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

        var stars = this.physics.add.group({
            key: 'star',
            repeat: 11,
            setXY: { x: 12, y: 0, stepX: 70 }
        });

        stars.children.iterate(function (child) {

            child.setBounceY(Phaser.Math.FloatBetween(0.4, 0.8));

        });

        this.scoreText = this.add.text(16, 16, 'score: 0', { fontSize: '32px', fill: '#000' });

        this.physics.add.collider(player, platforms);
        this.physics.add.collider(stars, platforms);

        this.physics.add.overlap(player, stars, this.collectStar, null, this);

        this.player = player;
    }

    function update()
    {
        var cursors = this.cursors;
        var player = this.player;

        if (cursors.left.isDown)
        {
            player.setVelocityX(-160);

            player.anims.play('left', true);
        }
        else if (cursors.right.isDown)
        {
            player.setVelocityX(160);

            player.anims.play('right', true);
        }
        else
        {
            player.setVelocityX(0);

            player.anims.play('turn');
        }

        if (cursors.up.isDown && player.body.touching.down)
        {
            player.setVelocityY(-330);
        }
    }

    function collectStar(player, star)
    {
        star.disableBody(true, true);

        this.score += 10;
        this.scoreText.setText('Score: ' + this.score);
    }



var config = {
    type: Phaser.AUTO,
   
    width: 800,
    height: 600,
    
    physics: {
        default: 'arcade',
        arcade: {
            gravity: { y: 300 },
            debug: false
        }
    }
    
};

var game = new Phaser.Game(config);

How are you setting up your game’s config object?

@julianos This is just to say thanks. I was struggling with something similar. This explanation helped. @Lteo Hat to you also
