Hi Simon,

calling the ArchitectView.callJavaScript function will simply execute whatever string you pass as JavaScript in your AR world.

Here's an example of that:

JavaScript:

var World = {
    myFunction: function(myParameter) {
    {
        alert("myFunction " + myParameter);
    }
};

C#:

int myInputParameter = 2;
callJavaScript("World.myFunction(" + myInputParameter + ");");

This will invoke the anonymous function behind the myFunction field from native code and create an alert saying "myFunction 2". I'm not perfectly sure this is syntactically correct C#, but you get the idea.
