```csharp
public static void ExternalCall(string functionName, params object[] args)
```

### Parameters

### Remarks

ExternalCall calls `functionName` in the web page containing the WebGL player, passing the given arguments to it. Supported argument types are the primitive types (string, `int`, `float`, char) and arrays of such types. Any other objects are converted to `string` using `ToString` and passed as `string`s.
