Question

我有一个组，我希望从左到右生成两种类型的块，反之亦然。这并不重要;我的随机化似乎工作正常，但问题是他们只有在我刷新游戏时才会改变。但是，如果我按原样运行它，它将永远是同一种块，直到我刷新。我该如何解决这个问题？

createOnebloque: function () {
    this.bloquecs = ["bloqueSprite", "bloquelSprite"]; ////// Here are the 2 sprites
    this.bloquesr = this.bloquecs[Math.floor(Math.random() * 2)]; /// Here I randomize, but it only works when I refresh.
    this.bloque = this.game.add.group();
    this.bloque.createMultiple(5, this.bloquesr);
    this.bloque.setAll('anchor.x', 0.5);
    this.bloque.setAll('anchor.y', 0.5);
    this.bloque.setAll('outOfBoundsKill', true);
    this.bloque.setAll('checkWorldBounds', true);
},

makeBloques: function () {
    this.bloques = this.bloque.getFirstExists(false);
    if (this.bloques) {
        this.bloques.reset(1440, 1400);
        this.game.physics.arcade.enable(this.bloques);
        this.bloques.enableBody = true;
        this.bloques.body.immovable = true;
        this.bloques.body.velocity.x = -2000;
    }
}

以下是创造功能：

this.game.physics.arcade.collide(this.bullets, this.bloque, this.collisionBulletBloque, null, this);

你的问题来自：

this.bloquesr = this.bloquecs[Math.floor(Math.random() * 2)];

您选择一个随机密钥，然后再使用它。

您可以像这样重写第一个函数：

createOnebloque: function () {
    this.bloquecs = ["bloqueSprite", "bloquelSprite"];
    this.bloque = this.game.add.group();

    for (var i = 0; i < 5; i++) {
        this.bloque.create(this.bloquecs[Math.floor(Math.random() * this.bloquecs.length]);
    }
    this.bloque.setAll('anchor.x', 0.5);
    this.bloque.setAll('anchor.y', 0.5);
    this.bloque.setAll('outOfBoundsKill', true);
    this.bloque.setAll('checkWorldBounds', true);
}

我没有对它进行过测试，但它应该有效。
