游戏引擎engine.js
/*
游戏引擎
*/
var Engine = {
//刚开始的游戏状态
gameStatus:false,
//所以敌机
enemy:{},
//子弹
bullet:{},
//得分
score:0,
//背景图片
game:document.querySelector(‘.game‘),
//初始化
init:function(){
this.gameStart();
},
//游戏开始
gameStart:function(){
var _this = this;
//点击图片的时候判断游戏状态
this.game.onclick = function(){
if(!_this.gameStatus){
_this.gameStatus = true;
//移动移动
_this.bgMove();
}
}
},
//背景移动
bgMove:function(){
var y=0;
var _this = this;
this.bgTimer = setInterval(function(){
y+=2;
_this.game.style[‘background-position-y‘]=y+‘px‘;
},50)
}
};
Engine.init();
如果做到这的话点击game背景会移动
