How to Invert Mouse movement settings

I started the basic application from the tutorial guide, and here is the relevant code to my problem:

public class MyGame extends SimpleApplication {
    public static void main(String[] args) {
        MyGame app = new MyGame();
        AppSettings settings = new AppSettings(false);
        settings.setTitle("My Awesome Game");
        // Configure settings before app.start

The problem is that I don’t like the way the mouse moves by default. When I move it down it goes up, and when I move it left it goes right.

I tried to change the settings with:
settings.setEmulateMouseFlipAxis(true, true);

But the mouse controls are the same.

Does anyone know where I should change the mouse settings?

So this is on Android or?

Edit: also, to be clear, if you’ve just made a blue cube app and think “left makes it go right”… that’s not true. Move mouse left, looks left… so the blue cube moves right in your view. That’s not backwards. That’s first person camera.

I used this:
float camSpeed = -10; // changing the sign you flip the directions
to invert both the directions axis of the mouse.
