物理不起作用

Question

嘿伙计，所以我有一个由地图集加载的精灵，我无法移动或应用物理到它，请看下面的代码：

谁能告诉我，我做错了什么？基本上我得到的只是精灵而不是在屏幕边缘移动。

//I load here:

  this.load.atlas('Monsters', 'images/monsters.png', 'images/monsters.json');


/////////timer to initiilize

 this.timerFiguras = this.time.events.loop(1000, this.makeFiguras, this);


/////////// below that 2 functions

 makeOneFigura: function() {

         this.figurai = this.game.add.sprite(0, 450, 'Monsters', this.rnd.integerInRange(0,4));
    this.figura = this.game.add.group();
    this.figura.enableBody = true;
      this.game.physics.p2.enable(this.figura, false);
   this.figura.add(this.figurai);
    this.figura.setAll('anchor.x', 0.5);
    this.figura.setAll('anchor.y', 0.5);
    this.figura.setAll('outOfBoundsKill', true);
    this.figura.setAll('checkWorldBounds', true); 

},


  makeFiguras: function(){ 

     this.figuras = this.figura.getFirstExists(false);
    if (this.figuras) {
        this.figuras.reset(0, 450);

                this.figuras.body.velocity.x = 1000;
        }


},
