这篇文章主要为大家详细介绍了js html5 css俄罗斯方块游戏实现代码,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

这个游戏主要分为三部份,HTML5+CSS+JAVASCRIPT来完成的。在这里详细讲一下js的代码。因为这个游戏的主要部分其实就是js。

大多数都是靠js来完成的。


完成后的效果如下:

HTML代码:

<body> 
 <div class="wrap"> 
 <div class="play_wrap"> 
 <div id="play_area"></div> 
 <div class="play_menu"> 
 <p>下一个:</p> 
 <div id="play_nextType"></div> 
 <a id="play_btn_start" class="play_btn" href="javascript:void(0);" 
 unselectable="on">开始</a><a id="play_btn_level" class="play_btn" href="javascript:void(0)" unselectable="on"><span class="level_text">中等</span class="level_icon"></span></a> 
 <div class="level_menu" id="play_menu_level"> 
 <ul> 
 <li><a href="javascript:void(0)" level=0>简单</a></li> 
 <li><a href="javascript:void(0)" level=1>中等</a></li> 
 <li><a href="javascript:void(0)" level=2>困难</a></li> 
 </ul> 
 </div> 
 <p> 
 分数:<span id="play_score">0</span> 
 </p> 
 <p> 
 方向:<span id="play_direction">bottom</span> 
 </p> 
 <p> 
 说明:<br> -“下”、“左”、“右”键控制方向,“上”为变形;<br> -游戏开始前、暂停时可调整难度;<br> 
 -难度分“简单”、“中等”、“困难”三级;<br> -对应的分值为10、20、40;<br> 
 -多行同时消去的倍数为1、4、10、20; 
 </p> 
 </div> 
 </div> 
 </div> 
 </body>

CSS代码:

HTML的代码其实就是一个游戏结构的框架,这里框架其实就是几个div的东西,所以不会太长,理解起来也是挺容易的。而CSS则是控制网页的布局与美观,所以要想吸引玩家,那CSS方面必须下功夫,而这里的CSS只是其实就将游戏区域与菜单区域分为左右两边了。而游戏域内的一个个框其实就是多个div,整齐排列在一起而已。

狼蚁网站SEO优化到了js了:

因为在代码已经将一些重要的部分做了注释,所以就不打算逐步分去分析了。说一下整体的写法吧。其实它首先是直接定义了一些图形的坐标,然后根据这些坐标画出一个下一个的图形出来,之后就是利用一个setInterval函数在游戏区域标出每个点,如果不能下落了就直接清除掉时间函数,之后在调用一个创建时间函数的函数出来,在画一个图形出来。具体的细节就看代码吧。
