<p>初到项目组，还是应该做一些有特色的东西，于是想到除了在功能上多做支持外，必须在专项上给到一定的支持，
正好这个时候项目组还是很关注客户端性能的，自然的就接手这一块东西了。</p>
<p>以前对客户端性能的了解不算太多，而我们的游戏采用unity3d进行的开发，刚接手这块东西，自然就会想到是否引擎上有自带
的支持工具，简单一搜一大堆的Profiler介绍，于是便从Profiler着手开始学习和进行性能优化。</p>
<p>以下简单总结下这几日的使用心得和一些注意事项：</p>
<h4>1.使客户端支持Profiler性能调优</h4>
<p>要想使得客户端能够直接使用Profiler进行调优，那么在编译客户端的时候必须勾选<code>development</code>选项，如果是自行封装的命令行编译
也可在其中加上相应的选项以支持development。</p>
<h4>2.通过development版本进行性能版本收集与分析</h4>
<p>使用android真机连接profiler进行性能分析时，需要先执行<code>adb forward tcp:54999 localabstract:Unity-进程名</code>，执行成功后，
运行游戏，运行profiler，如果没问题就可以看到profiler收集到的性能数据了</p>
<h4>3.关注的数据</h4>
<p>在profiler中我们通常关注cpu，render，memory，观察游戏场景中的曲线走势图，选择游戏中的某点查看该点对应的函数执行，贴图信息。
但需要注意profiler不能往回查看以前的信息，不过我们可以在收集到疑似问题点后，点击<code>record</code>暂停纪录，然后分析疑似问题点。
当然比较方便的是直接开启两个profiler对比同一场景中的函数运算，场景贴图信息。
设置开启两个unity的方法：<code>Edit</code>-&gt;<code>preference</code>-&gt;<code>open project dialog always</code>。</p></div></description><category>u3d</category><guid>http://nicebug.github.io/posts/use-unity3d-profiler-basic/</guid><pubDate>Wed, 15 Apr 2015 13:23:36 GMT</pubDate></item><item><title>learning web.py</title><link>http://nicebug.github.io/posts/learning-webpy/</link><dc:creator>damonhu</dc:creator><description><div><h3>web.py学习笔记</h3>
<p>由于后台的几个需求，需要给测试同学构造gm指令以方便测试，思来想去还是搭建个快速的webserver来方便测试同学，django太庞大，tornado不大熟悉，别人介绍了下<a href="http://webpy.org/">web.py</a>，而且也不需要安装一大堆的第三方依赖库(原谅楼主有时候在服务器上不喜欢装第三方库的臭毛病吧)，甚至把web.py打包后都不需要额外安装任何东西。简单看了下web.py的文档，感觉还是入手还是比较容易。</p>
<p>工程文档目录结构：</p>
<pre class="code literal-block"><span></span>main
|---- conf (工程配置文件)
|---- static (js，图片等)
|---- template (html文件)
|---- web (web.py的库文件)
|---- config.py (目录，密码等配置)
|---- index.py (路由文件)
</pre>
<p>接着就可以开始coding，在web.py中需要指定url路由,当url请求中包含相应关键字时则跳转到相应的class中进行处理。</p>
<pre class="code literal-block"><span></span><span class="n">urls</span> <span class="o">=</span> <span class="p">(</span>

<p>当POST请求跳转到bin_upload时，则跳转到Upload进行相应的处理，Upload中处理接收的参数，进行后台逻辑处理。如果需要将处理后的数据返回前台，通常使用render来处理返回的数据<code>render.htmlfilename(parms)</code>的方式。</p></div></description><category>web.py</category><guid>http://nicebug.github.io/posts/learning-webpy/</guid><pubDate>Thu, 05 Feb 2015 03:49:39 GMT</pubDate></item><item><title>markdown syntax</title><link>http://nicebug.github.io/posts/markdown-syntax/</link><dc:creator>damonhu</dc:creator><description><div><!--
::最后一次在成都测试组KM吧发文了
-->
<p>想写文章但一直纠结于文章的排版？屌丝哪有那么多时间在排版上纠结，于是试试最近比较火的<code>markdown</code>吧，从此告别各种一级标题，二级标题各种纠结的排版。</p>
<p>Markdown的目标是实现[易读易写]。</p>
<p>可读性，无论如何，都是最重要的。一份使用 Markdown 格式撰写的文件应该可以直接以纯文本发布，并且看起来不会像是由许多标签或是格式指令所构成。Markdown语法受到一些既有 text-to-HTML的影响，包括Setext、atx、Textile、reStructuredText、Grutatext 和EtText，而最大灵感来源其实是纯文本电子邮件的格式。</p>
<h2>区块元素</h2>
<h3>标题</h3>
<p>标题就是word中我们经常看到的标题1...，是文档的必备元素。以下为各级标题的效果展示和基础语法。</p>
<h2>标题1</h2>
<pre class="code literal-block"><span></span># 标题1
</pre>
<h3>标题2</h3>
<pre class="code literal-block"><span></span>## 标题2
</pre>
<h6>标题6</h6>
<pre class="code literal-block"><span></span>###### 标题6
</pre>
<h6># 标题7</h6>
<pre class="code literal-block"><span></span>####### 标题7；没有标题7了，该格式无效
</pre>
<h3>区块引用</h3>
<p>Markdown标记区块引用类似email中用<code>&gt;</code>的引用方式。如果你还熟悉在 email 信件中的引言部分，你就知道怎么在 Markdown 文件中建立一个区块引用，那会看起来像是你自己先断好行，然后在每行的最前面加上<code>&gt;</code></p>
<blockquote>
<p>markdown syntax
markdown2
markdown 3</p>
</blockquote>
<pre class="code literal-block"><span></span>&gt; markdown syntax
&gt; markdown2
&gt; markdown 3
</pre>
<p>区块引用可以嵌套（例如：引用内的引用），只要加上不同数量的<code>&gt;</code>即可。</p>
<blockquote>
<p>markdown syntax</p>
<blockquote>
<p>markdown2
</p>
</blockquote>
</blockquote>
<pre class="code literal-block"><span></span>&gt; markdown syntax
&gt; &gt; markdown2
</pre>
<h3>列表</h3>
<p>Markdwon支持有序和无序两种列表。</p>
<p>无序列表使用星号、加号或减号作为列表标记：</p>
<ul><li>列表1</li>
<li>列表2</li>
<li>列表3</li>
</ul><pre class="code literal-block"><span></span>* 列表1
* 列表2
* 列表3
</pre>
<p>有序列表使用数字加英文句点的方式：</p>
<ol><li>有序1</li>
<li>有序2</li>
<li>有序3</li>
</ol><h3>代码区块</h3>
<p>Here is an example of python:</p>
<pre class="code literal-block"><span></span><span class="kn">import</span> <span class="nn">os</span>
<span class="k">print</span> <span class="s2">"hello world"</span>
</pre>
<h3>分隔线</h3>
<p>在一行中使用三个以上的星号，建号，底线来建立分隔线。</p>
<hr><hr><pre class="code literal-block"><span></span>-------------------
**************
</pre>
<h2>区段元素</h2>
<h3>链接</h3>
<p>Markdown 支持两种形式的链接语法： 行内式和参考式两种形式。不管是哪一种，链接文字都是用 [方括号] 来标记。</p>
<h4>行内式</h4>
<p>This is <a href="http://www.oa.com/" title="tips">OA</a> website.</p>
<pre class="code literal-block"><span></span>This is [OA](http://www.oa.com/ "tips") website.
</pre>
<h4>参考式</h4>
<p>This is <a href="http://www.oa.com/" title="tips">OA</a> website.</p>
<pre class="code literal-block"><span></span>This is [OA] [1] website.
[1]: http://www.oa.com/ "tips"
</pre>
<h3>强调文字</h3>
<p>Markdown使用星号(<code>*</code>)和底线(<code>_</code>)作为强调字词的符号。
<em>this is markdown</em></p>
<pre class="code literal-block"><span></span>*this is markdown*
</pre>
<p><strong>this is markdown too</strong></p>
<pre class="code literal-block"><span></span>**this is markdown too**
</pre>
<p>本文只是markdown一些常用语法的小科普，更多详细内容请自行脑补。
