# WebViewHook
> Warning: WebViewHook is obsolete for Unity 2020 and Above due to removal of Asset Store Browsing in Unity Editor. This project is soon to be archived.
This is a code snippet to access a hidden `WebView` API from Unity Editor, and load it to `EditorWindow`.
## Code
Download [WebViewHook](Assets/Editor/WebViewHook.cs). See usage example in [WebWindow](Assets/Editor/WebWindow.cs) or [WebEditor](Assets/Editor/WebEditor.cs). You may download the whole project if necessary.
## Usage
Minimum code to get WebView working:
```c#
class WebViewDemo : EditorWindow
{
WebViewHook webView;
void OnEnable()
{
if (!webView)
{
// create webView
webView = CreateInstance();
}
}
public void OnBecameInvisible()
{
if (webView)
{
// signal the browser to unhook
webView.Detach();
}
}
void OnDestroy()
{
//Destroy web view
DestroyImmediate(webView);
}
void OnGUI()
{
// hook to this window
if (webView.Hook(this))
// do the first thing to do
webView.LoadURL("https://google.com");
if (ev.type == EventType.Repaint)
{
// keep the browser aware with resize
webView.OnGUI(new Rect(Vector2.zero, this.position.size));
}
}
}
```
## Two Way Communication
Using `LoadURL`, `LoadHTML` and `ExecuteJavascript` you only can send information to WebView.
To extract informations from WebView you need external communication, and the easiest way to do this is by using [Web Socket](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API).
To get web socket server running you need to download [WebSocket-Sharp](https://github.com/sta/websocket-sharp) and a [script utility from this repo](Assets/Editor/WebSocketHook.cs).
See [WebData](Assets/Editor/WebData.cs) for minimal working example of using `WebSocketHook` to hook C# into javascript variable.
## More Information and Caveats
**This is an editor only solution.** If you're looking to add WebView to a game build then this is not the repo you're looking for.
The technology behind `WebView` is [Chrome Embedded Framework](https://en.wikipedia.org/wiki/Chromium_Embedded_Framework), [version 37](https://twitter.com/willnode/status/955079655630913541). In Windows it's contained inside the gigantic `libcef.dll`.
`WebView` in Unity is just like Chrome, with background-color default to darkgrey and no plugins (Flash/Java/PDF) allowed.
I solving bugs as I can, but of course limited. If you can't open a specific website, mostly comes down to the fact that Unity haven't upgrade their CEF browser.
