Add parameter to a child's contructor while create its group.

[Thao Cao Minh]

I have a problem while create a group, that i want to add parameter to the children of the group. I logged the group, it showed that it was a list of children. But the next line i tried to interate them to set property for its child, the length of list = 0; I don't know how to deal with this problem, so...

Thank you for reading this.

This is my code:

// this is in the GameScene create group function

    var bullets = context.add.group({

        classType: Bullet,

        runChildUpdate: true,

        maxSize: 40

    });

    console.log(bullets.getChildren());                                                                   /* The log show that have a mount of child in it */

    bullets.getChildren().forEach(element => {                                       /* The none of children so the bullets.length = 0, nothing change to the pivot */                    

        element.setPivot(pivot);

    });

 

export default class Bullet extends Phaser.Physics.Arcade.Sprite {

    constructor(scene) {

        super(scene, 0, 0, 'dan1');

        this.pivot = 0;

        this.power = 1;

        scene.physics.world.enable(this);

        this.speed = Phaser.Math.GetSpeed(400, 1);  // 400px/1s

    }

    preload() { }

    create() { }

    update(time, delta) {

        this.y -= this.speed * delta;

        this.x -= this.pivot * (this.speed / this.originalY) * delta;

        if (this.y < -50) {

            this.destroy(true);

        };

    }

    fire(x, y) {

        this.originalY = y - 20;

        this.setPosition(x, y - 20);

        this.setActive(true);

        this.setVisible(true);

    }

    setPivot(newPivot) {

        this.pivot = newPivot;

    }

    

}
