Inherit from javascript function

[lcnvdl]

Hi! I'm using jsface for the new objects of my project, but I have a lot of "legacy objects", like:

var Robot = function() {

    this.getRotation = function() { return 0; }

};

I'm trying to create a child of Robot using jsface, like:

var RobotChild = Class(Robot, function() {
    return {
    };
});

But, when I do:

var robot = new RobotChild();

I get an empty instance.

Regards

What do you mean you get an empty instance? I run the snippet, robot does have properties:

typeof robot; // "object"
typeof robot.getRotation; // "function"
robot.getRotation(); // 0
