phaser.sprite.body overlap collide seperate

1.sprite开启物理系统

        this.sp1 = new Phaser.Sprite(game, 400, 400, 'yellow_png');
        this.group.addChild(this.sp1);
        game.physics.enable([this.sp0, this.sp1], Phaser.Physics.ARCADE);
        this.sp0.body.velocity = new Phaser.Point(600, 500);
        this.sp1.body.velocity = new Phaser.Point(-120, -150);
        this.sp0.body.collideWorldBounds = true;
        this.sp1.body.collideWorldBounds = true;

2.sprites overlap collide seperate的检测

http://www.html5gamedevs.com/topic/9522-phaserarcade-collide-and-overlap-difference-and-separation/

关于overlap()无法正常工作

在update(){}中检测：

  update() {
        this.game.physics.arcade.overlap(this.sp0, this.sp1, () => { console.log('overlap'), this });
        this.game.physics.arcade.separate(this.sp0.body, this.sp1.body, () => { console.log('separate') }, this);
        this.game.physics.arcade.collide(this.sp0, this.sp1, () => { console.log('collide'), this });
}

• overlap

3.group没有x,y,position属性，设置的x,y,position属性无效。

办法：为group添加容器，设置容器的位置。
