本文实例为大家分享了jQuery实现飞机大战游戏的具体代码，供大家参考，具体内容如下
一、效果图
二、核心代码
1.创建地图
this.createMap = function () {
var that = this;
that._bg = $("<div class='bgmap'></div>");
that._bg.css({
width: sw,
height: sh,
backgroundPosition: '0px ' + (-sh) + 'px'
});
mapEle.append(that._bg);
this.startAnimate();
//创建分数
that.score=$("<span class='score'>0</span>");
mapEle.append(that.score);
}; 2.用户选择飞机界面
this.createPage=function(){
var that=this;
that._userPage=$("<div class='user_check'></div>");
that._userplane[0]=$("<div class='plane1'><img class="lazy" data-src='./img/my_1.png'></div>");
that._userplane[1]=$("<div class='plane2'><img class="lazy" data-src='./img/my_2.png'></div>");
that._userplane.map(function (item,index){
!index?item.addClass("check"):'';//默认第一个选中
that._userPage.append(item);
item.on("click",function(){
//设置二选一
$(this).addClass("check").siblings().removeClass("check");
});
});
that._start = $("<button class='start'>开始</button>");
that._start.on("click",function(){
that._userplane.map(function(item,index){
if(item.hasClass("check")){
that._userPage.hide();
//开启背景动画
that.startAnimate();
//获取用户选择的飞机的图片路径
that._userFeiclass="lazy" data-src=item.find("img").attr("class="lazy" data-src");
that._plane.createUser(that._userFeiclass="lazy" data-src);
}
})
});
that._close = $("<button class='start'>关闭</button>");
that._close.on("click",function(){
//浏览器关闭
window.close();
})
that._userPage.append(that._start);
that._userPage.append(that._close);
mapEle.append(that._userPage);
} 3.设置背景循环
this.startAnimate=function(){
var that=this;
that._bg.animate({
backgroundPositionY:0
},5000,'linear').queue(function(){
$(this).css({
backgroundPosition:'0px '+(-sh)+'px'
}).dequeue();
that.startAnimate();
});
}; 4.创建飞机
this.createUser=function(class="lazy" data-src){
var that=this;
that._user=$("<img class='user' class="lazy" data-src="+class="lazy" data-src+"/>");
mapEle.append(that._user);
that._user.css({
top:sh,
left: sw / 2 - 30
}).animate({
top:that.pos.top
},1000,function(){
//动画执行完成之后用户开始操作
console.log("开始触屏");
//给当前飞机添加触屏事件
that.addTouch();
//设置子弹几发，并且开始发射
that.gun();
//敌机开始动
that.randomEnemy();
});
}; 5.创建敌机
this.createEnemy = function () {
var that = this;
that.index = Math.floor(Math.random() * that.enemylist.length);
var wrandom = Math.random() * sw;
var ele = that.enemylist[that.index];//获取当前的敌机
that.enemy = $("<img class='enemy'/>");
mapEle.append(that.enemy);
that.top = ele.direct == 'todown' ? -ele.h : sh + ele.h;
that.left = wrandom - ele.w < 0 ? 0 : wrandom + ele.w > sw ? sw - ele.w : wrandom;
that.w = ele.w;
that.h = ele.h;
that.enemy.css({
width: that.w,
height: that.h,
left: that.left,
top: that.top
}).attr("class="lazy" data-src", ele.class="lazy" data-src);
that.blood = ele.blood;
that.score = ele.score;
that.way = ele.direct;
that.speed = ele.speed;
//敌机移动
that.move();
}; 6.敌机移动
this.move=function(){
var that=this;
if(that.way=="todown"){
that.top+=that.speed;
if(that.top>=sh){
that.enemy.remove();
return;
}
}
else{
that.top-=that.speed;
if(that.top<=0){
that.enemy.remove();
return;
}
}
that.enemy.css({
top: that.top
});
that.timer=setTimeout(function(args){
args.move();
},that.tspeed,that)
} 7.设置敌机爆炸
this.blow = function (index) {
var that = this;
//开始爆炸
that.blowool = true;
that.enemy.remove();
//加分
allsc+=that.score;
$(".score").text(allsc);
//在原位置创建爆炸
var b = $("<img class='blow' class="lazy" data-src='./img/blow.gif'/>");
b.css({
left: that.left,
top: that.top,
width: that.w,
height: that.h
});
b.timer = setTimeout(function (arg) {
arg.remove();
}, 300, b)
mapEle.append(b);
allEnemy.splice(index, 1);
}; 8.创建子弹
this.createBullet=function(pos,left){
this._bullet = $("<img class='bullet' class="lazy" data-src='" + this.img + "'/>");
mapEle.append(this._bullet);
//设置当前子弹的坐标
this.top = pos.top - 20;
this.left = left - this.w / 2;
this._bullet.css({
width: this.w,
height: this.h,
left: this.left,
top: this.top
});
this.move();
} 9.检测子弹的移动（是否打到敌机）
this.move=function(){
var that=this;
that.top-=that.dus;
if(that.top<=0){
that._bullet.remove();
return;
}
//在子弹里面去检测 是否打到敌机
that = that.checkEnemy();
//检测子弹如果为null 直接出
if (that == null)
return;
that._bullet.css({
top: that.top
});
that.timer=setTimeout(function(args){
args.move();
},that.speed,that);
}; 10.设置敌机被消灭的情况
this.checkEnemy = function () {
var that = this;
//left top
for (var i = 0; i < allEnemy.length; i++) {
var item = allEnemy[i];
//检测条件
if (item.blowool == false && that.left + that.w >= item.left && that.left <= item.left + item.w && that.top <= item.top +
item.h && that.top + that.h >= item.top) {
//开始血量减少
item.blood -= 1;
if (item.blood <= 0) {
//敌机移除
item.blow(i);
}
//子弹移除
that._bullet.remove();
//移除子弹对象
return null;
}
}
return that;
