Unity3D WebView

Unity 3D에서 WebView를 쓸 때 유용한 소스 입니다. 

일본 개발자분이 오픈소스로 라이센스로 공개한 것 같더군요...

[소스]

https://github.com/gree/unity-webview

- Java로 작성된 Android 용 Native Plugin

- Objective-C로 작성된 iOS 용 Native Plugin

- Objective-C로 작성된 OS X 용 Native Plugin

- Native Plugin을 사용하기위한 C # Plugin

[예제 프로젝트]

https://github.com/keijiro/unity-webview-integration

unity-webview-integration 소스는 웹 페이지를 WebView로 호출에서 아래와 같이 unity와 기능을 연동한 예제 입니다.

javascript 예제여서 좀 아쉽네요. C#으로 수정해봐야 겠습니다.
