unity与android交互的由来

本人在项目开发过程中，遇到这样一个需求，把unity的场景放到android中去显示。刚开始做的时候也是一头雾水，unity是什么东西都没听说过。后来也是查询很多资料，才实现了需求的效果。所以把自己的一些总结记录于此，方便各位同行参考。

unity简单介绍

unity是可以开发诸如三维视频游戏、建筑模型、三维动画等交互类内容的多平台综合游戏开发工具，具有很强大的跨平台性。在unity之中编写好场景和程序之后，可以导出Android、ios、windows phone、PC等多个平台的版本。

图片名称

如上图，列出了unity可以导出的所有平台。

unity与android交互介绍

一般的都是，把unity作为android程序中的一部分，将一个u3d场景当成一个界面或者一个界面的一部分。
还有的是把android作为unity的一部分进行开发。不过这种形式的开发很少，也没必要。

我们下面以一个例子来介绍二者之间的交互。

首先，在unity中搞了一个游戏场景，运行之后如下图：

图片名称

此场景中“1”是一个label，用来显示从android中设置的怪兽人物的名称。“2”用于在android程序中控制大小显示变化的。“3”是用与unity中测试大小变化的。

unity调用android的方法

我们需要在运行起来Unity引擎之后，调用java类中的方法获取怪兽的姓名，就需要Uniy调用Android的方法。
unity调用java方法一共有四种形式，分别是：

没有返回值的普通方法

<code class="hljs vbnet has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">AndroidJavaObject jo = <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">new</span> AndroidJavaObject(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"android.content.res.Configuration"</span>);jo.<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">Call</span>(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"setToDefaults"</span>);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>

带有返回值的普通方法

没有返回值的静态方法

代码和场景编写好之后，就可以使用unity到处apk文件运行了。不过我们需要在eclipse中进行二次开发，所以需要到处android工程。

在导出的时候，可以选择导出”Google Android Project”。

图片名称

如上图，如果不勾选此选项，则导出的是一个apk文件。
在导出android工程或apk之前，需要在”Player Settings”进行一些配置:

图片名称

这些配置与我们在eclipse等工具进行开发设置的基本一致。
导出android工程之后，看到目录结构如下：

这里写图片描述

assets文件下面是unity的一些资源文件，包括场景和渲染的文件。
libs下面当然就是jar包和so文件了。
src下面包含三个java类。建议使用UnityPlayerActivity.java

打开UnityPlayerActivity之后，会发现里面有一个对象时UnityPlayer的实例，我们做android中嵌套U3D场景的时候，就是把这个实例当成一个view添加到我们的布局中。

导出android工程之后，会出现两种情况：

你已经有android工程了，此时只需要把assets的文件和libs的包拷贝到你的项目中去，在把需要配置的类在AndroidManifest.xml中配置一下。
没有工程，那么只需要把unity导出的工程导入你的IDE中即可。

看一下MainActivity的布局：

贴上逻辑代码之前，先介绍一下Android调用unity方法的方式：

android调用untiy的方法：

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">UnityPlayer<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.UnitySendMessage</span>(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"Manager"</span>, <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"ZoomIn"</span>, <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">""</span>)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

第一个参数是Game Object对象，所以需要在游戏对象上绑定脚本，第二个参数是unity中定义的方法名，第三个参数是定义方法的参数（可空）。

图片名称

既可以在定义场景的时候将游戏对象改名字，也可以在代码中设置：

<code class="hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">void</span> Start () {  <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">this</span>.name = <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"Manager"</span>;  GetData (); }</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

在unity中运行之后，就会发现出现一个”Manager”的游戏场景了。
