### 概要

Unity iOS および Android において web view を画面内に組み込み、その内部と連携を行うためのプラグインの実装例です。

![screenshot](https://github.com/downloads/keijiro/unity-webview-integration/IMG_0004.jpg)

上図は実装されたサンプルシーンを実行した様子です。上部が Unity の画面で、下部が web view です。Web view 内のリンクをクリックすることにより Unity 画面内で特定のアクションが発動されます。

### 簡単な解説

#### Unity 側

[Assets/Plugins/WebMediator.js](https://github.com/keijiro/unity-webview-integration/blob/master/unity/Assets/Plugins/WebMediator.js) が Unity 側の窓口となるスクリプトです。このスクリプトを通して web view の表示制御、配置マージン設定、指定 URL のロードを行うことができます。また、web view 内から送信されたメッセージをここから拾い上げることができます。詳しい使用方法についてはサンプルプロジェクトの [TestInterface.js](https://github.com/keijiro/unity-webview-integration/blob/master/unity/Assets/Scripts/TestInterface.js) を参照してください。

#### Web view 側

Web view 側からメッセージを送信するには [unity.js](https://github.com/keijiro/unity-webview-integration/blob/gh-pages/unity.js) をインポートし、この中で定義されている `UnityWebMediator` クラスを用いる必要があります。詳しい使用方法についてはサンプルプロジェクトの [index.html](https://github.com/keijiro/unity-webview-integration/blob/gh-pages/index.html) を参照してください。

# You can use this to override default values such as
#  'source.dir' for the location of your java source folder and
#  'out.dir' for the location of your output folder.

# You can also use it define how the release builds are signed by declaring
# the following properties:
#  'key.store' for the location of your keystore and
#  'key.alias' for the name of the key to use.
# The password will be asked during the build when you use the 'release' target.

    <!-- The ant.properties file can be created by you. It is only edited by the
         'android' tool to add properties to it.
         This is the place to change some Ant specific build properties.

             The name of the output directory. Default is 'bin'.

         For other overridable properties, look at the beginning of the rules
         files in the SDK, at tools/ant/build.xml

         Properties related to the SDK location or the project target should
         be updated using the 'android' tool with the 'update' action.

         This file is an integral part of the build system for your
         application and should be checked into Version Control Systems.

    <property file="ant.properties" />

    <!-- The project.properties file is created and updated by the 'android'
         tool, as well as ADT.

         This contains project specific properties such as project target, and library
         dependencies. Lower level build properties are stored in ant.properties
         (or in .classpath for Eclipse projects).

         This file is an integral part of the build system for your

    <!-- Import the actual build file.

         To customize existing targets, there are two options:
         - Customize only one target:
             - copy/paste the target into this file, *before* the
               <import> task.
             - customize it to your needs.
         - Customize the whole content of build.xml
             - copy/paste the content of the rules files (minus the top node)
               into this file, replacing the <import> task.
             - customize to your needs.

         ***********************
         ****** IMPORTANT ******
         ***********************
         In all cases you must update the value of version-tag below to read 'custom' instead of an integer,
         in order to avoid having your file be overridden by tools such as "android update project"
    -->
