如何在Facebook即时游戏中为移动设备创建“移相器"按钮

问题描述

我正在尝试在移动设备上使用Phaser 2 CE创建一个按钮，但是即使在台式机上也能正常工作，它也不会触发，整个代码将位于我的github仓库，但目前我只能像下面的代码所示显示图像

I am trying to create a button with Phaser 2 CE on a mobile device but it doesn't fires, even if it works fine on desktop, the entiere code will be on my github repository but for the moment i can just display an image like in the code bellow

var game = new Phaser.Game(640, 480, Phaser.AUTO, 'game', { preload: preload, create: create, update: update });

function preload () {

  game.load.image('logo', 'assets/phaser2.png');
  game.load.image("upArrow", "assets/up.png");

}

function create () {
  // Initialize player
  //player = game.add.sprite(20, 20, 'logo');
  game.device.desktop || addMobileInputs();
}

function addMobileInputs() {
  upButton = game.add.sprite(40, 40, "upArrow");
  upButton.inputEnabled = !0;
  upButton.events.onInputDown.add(myHandler, this);
}

function myHandler() {
  alert("up");
}

function update() {

}

推荐答案

alert("...")似乎不会触发，并且代码是正确的，因为如果您仅移动精灵，它就会移动，例如像代码一样下方:

It seems that alert("...") doesn't fire, and the code is correct because if you just make your sprite move, it moves, for example like the code below:

var game = new Phaser.Game(640, 480, Phaser.AUTO, 'game', { preload: preload, create: create, update: update });
var sprite;

function  preload () {
  // This is equivalent to <https://examples.phaser.io/assets/>.
  this.load.image('dude', 'assets/sprites/phaser-dude.png');
}

function create() {
  sprite = game.add.sprite(game.world.centerX, game.world.centerY, 'dude');
  sprite.inputEnabled = true;
  sprite.events.onInputDown.add(myHandler, this);
}

function myHandler() {
  sprite.x += 10;
}

function update() {
}
