The second animation gives an error, help!

[agonya]

Hello my dear friends, I am trying to add animation to my bird object and I added for normal flying and It worked but when I try to add any other animation to same object it gives an error can you help me, I am adding my codes and the error message here, thanks!

 

create: function() {
        
        
        this.bird = game.add.sprite(150, 200, 'bird');
        this.bird.scale.setTo(0.1, 0.1);
        this.game.physics.arcade.enable(this.bird);
        this.bird.body.gravity.y = 1000;
        this.bird.animations.add('right', [0, 1], 5, true);
        this.bird.animations.add('dead', [2, 3], 5, true);
        this.bird.anchor.setTo(-0.2, 0.5);
        
        var spaceKey = game.input.keyboard.addKey(Phaser.Keyboard.SPACEBAR);
		spaceKey.onDown.add(this.fly, this);
        
    },

update: function() {  
        this.game.physics.arcade.overlap(this.bird, this.blocks, this.killBird);
       
        
    },

  fly: function() {
	
		if (this.bird.alive == false)
		return; 
		
		this.bird.body.velocity.y = -325;
		
		var animation = game.add.tween(this.bird);
		animation.to({angle: -20}, 100);
		animation.start(); 
		this.bird.animations.play('right');
		
	},

killBird: function() {
        
        
        this.bird.animations.play('dead', 8, true);
        game.state.start('menu');
    },

And I add the error message, and also my other problem is about pixel reformatting errors, how can I get rid of them, thanks.

You need to pass a callback context in arcade.overlap.

Thank you, but how can I do it? My callback function is "this.killBird", Should it be like "this.killBird(this.bird)"? Sorry because I have been interested in Phaser for 20 days.  @samme

this.game.physics.arcade.overlap(this.bird, this.blocks, this.killBird, null, this);

@samme thanks a lot, you really helped me.
