JSFiddle のデモはこちらにありますが、以下のコードも貼り付けています。私の質問は単純です (ただし、これを実現する方法の例を見つけることができないようです): 今、JSFiddle でゲームを開始すると、長方形がすぐに「落ちる」ことがわかります。マウスでクリックしたときにゲームを開始したいのですが(基本的に、マウスの最初のクリックの前に何も起こりません)-これを達成する方法のポイントはありますか?
JS:
// Initialize Phaser, and creates a 400x490px game
var game = new Phaser.Game(400, 490, Phaser.AUTO, 'game_div');
var game_state = {};
// Creates a new 'main' state that wil contain the game
game_state.main = function () {};
game_state.main.prototype = {
preload: function () {
// Change the background color of the game
this.game.stage.backgroundColor = '#71c5cf';
// Load the bird sprite
this.game.load.image('bird', 'https://lh6.googleusercontent.com/Xrz0PnR6Ezg5_k5zyFKxGv0LzehAP9SMj_ga3qQzIF4JAfv8xHm7TxfliwtBD8ihfw=s190');
this.game.load.image('pipe', 'https://lh4.googleusercontent.com/RSMNhJ3KY4Xl0PQpUf6I9EayOdLhvOKKV9QV7_BXXYVedPy0oMNRFKANW14xV76NDA=s190');
},
create: function () {
// Display the bird on the screen
this.bird = this.game.add.sprite(100, 245, 'bird');
// Add gravity to the bird to make it fall
this.bird.body.gravity.y = 1000;
// Call the 'jump' function when the spacekey is hit
var space_key = this.game.input.keyboard.addKey(Phaser.Keyboard.SPACEBAR);
space_key.onDown.add(this.jump, this);
this.pipes = game.add.group();
this.pipes.createMultiple(20, 'pipe');
this.timer = this.game.time.events.loop(1500, this.add_row_of_pipes, this);
this.score = 0;
var style = {
font: "30px Arial",
fill: "#ffffff"
};
this.label_score = this.game.add.text(20, 20, "0", style);
},
update: function () {
// If the bird is out of the world (too high or too low), call the 'restart_game' function
this.game.physics.overlap(this.bird, this.pipes, this.restart_game, null, this);
if (this.bird.inWorld == false) this.restart_game();
},
// Make the bird jump
jump: function () {
// Add a vertical velocity to the bird
this.bird.body.velocity.y = -350;
},
// Restart the game
restart_game: function () {
// Start the 'main' state, which restarts the game
this.game.time.events.remove(this.timer);
this.game.state.start('main');
},
add_one_pipe: function (x, y) {
// Get the first dead pipe of our group
var pipe = this.pipes.getFirstDead();
// Set the new position of the pipe
pipe.reset(x, y);
// Add velocity to the pipe to make it move left
pipe.body.velocity.x = -200;
// Kill the pipe when it's no longer visible
pipe.outOfBoundsKill = true;
},
add_row_of_pipes: function () {
this.score += 1;
this.label_score.content = this.score;
var hole = Math.floor(Math.random() * 5) + 1;
for (var i = 0; i < 8; i++)
if (i != hole && i != hole + 1) this.add_one_pipe(400, i * 60 + 10);
},
};
// Add and start the 'main' state to start the game
game.state.add('main', game_state.main);
game.state.start('main');
