本文实例为大家分享了js+css实现飞机大战游戏的具体代码,供大家参考,具体内容如下
用js和css实现,css中定义样式,js中定义了具体的实现事件,例如碰撞、子弹、飞机等。
main.css文件(可根据需要定义):
*{ margin: 0; padding: 0; } #contentdiv{ position: absolute; left: 500px; } #startdiv{ width: 320px; height: 568px; background-image: url(../image/ks.png); } button{ outline: none; } #startdiv button{ position: absolute; top: 500px; left: 82px; width: 150px; height: 30px; border: 1px solid black; border-radius: 30px; background-color: #c4c9ca; } #maindiv{ width: 320px; height: 568px; background-image:url(../image/background_1.png) ; display: none; } #maindiv img{ position: absolute; z-index: 1; } #scorediv{ font-size: 16px; font-weight: bold; position: absolute; top: 10px; left: 10px; display: none; } #scorediv{ font-size: 18px; font-weight: bold; } #suspenddiv{ position: absolute; top: 210px; left: 82px; display: none; z-index: 2; } #suspenddiv button{ width: 150px; height: 30px; margin-bottom: 20px; border: 1px solid black; border-radius: 30px; background-color: #c4c9ca; } #enddiv{ position: absolute; top: 210px; left: 75px; border: 1px solid gray; border-radius: 5px; text-align: center; background-color:#d7ddde; display: none; z-index: 2; } .plantext{ width: 160px; height: 30px; line-height: 30px; font-size: 16px; font-weight: bold; } #planscore{ width: 160px; height: 80px; line-height: 80px; border-top: 1px solid gray; border-bottom: 1px solid gray; font-size: 16px; font-weight: bold; } #enddiv div{ width: 160px; height: 50px; } #enddiv div button{ margin-top:10px ; width: 90px; height: 30px; border: 1px solid gray; border-radius: 30px; }
