为了实现这一点,我有一个启动状态,在该状态下我初始化了各种与游戏相关的实用程序以及我想要在加载屏幕期间拥有的精灵。然后我只加载加载其他所有内容的预加载器状态,我只是将前一个精灵放在屏幕上。当一切完成后,主游戏或菜单状态开始。
这是一个例子:
Test.Boot.prototype = {
init: function () {
//general game config like scaleManager
},
preload: function () {
this.game.stage.backgroundColor = '#000000';
// the sprite you want to show during loading
this.game.load.atlasJSONHash('logo', 'asset/images/hand.png', 'asset/images/hand.json');
},
create: function () {
this.state.start('Preloader');
}
};
// Preloader.js
Test.Preloader.prototype = {
preload: function() {
//add the animation
this.logo = this.add.sprite(this.world.width/2, this.world.height/2, 'logo');
this.logo.anchor.set(0.5, 0.5);
this.logo.animations.add('shake',[8,9,10,11,12,13,14,15,16,17,17,8,9,8]);
this.logo.animations.play('shake', 60, true);
//load all the other assets
this.game.load.image("hero", "asset/images/hero.png");
this.game.load.image("clouds", "asset/images/sky3.jpg");
//this.game.load.image("rope", "asset/images/rope.png");
this.game.load.atlasJSONHash('items', 'asset/images/items.png', 'asset/images/items.json');
this.game.load.physics('physicsData', 'asset/images/polygon.json');
},
create: function() {
this.game.stage.backgroundColor = '#1589FF';
//A simple fade out effect
this.game.time.events.add(Phaser.Timer.SECOND * 2.0, function() {
var tween = this.add.tween(this.logo)
.to({alpha: 0}, 750, Phaser.Easing.Linear.none);
tween.onComplete.add(function() {
this.logo.destroy();
this.startGame();
}, this);
tween.start();
}, this);
},
startGame: function() {
this.state.start('MainMenu');
},
};
