Jinput - Get Mouse Location

Question

I am attempting to print out the mouse location using Jinput:

public static void main(String[] args) {
    input = new InputManager();

    while (true) {
        for (Mouse mouse : input.getMice()) {
            mouse.poll();
            System.out.println("Mouse X: " + mouse.getX().getPollData());
            System.out.println("Mouse Y: " + mouse.getY().getPollData());
            System.out.println("---------");
        }
        try {
            Thread.sleep(100);
        } catch (Exception e) {
            // DO NOTHING < BAD
        }
    }
}

Here is my InputManager, which upon initialization scans for all the input devices, and separates all the mice into a separate list:

public class InputManager {
    public ArrayList<Mouse> mice;

    public InputManager() {
        mice = new ArrayList<Mouse>();
        Controller[] inputs = ControllerEnvironment.getDefaultEnvironment()
            .getControllers();
        for (int i = 0; i < inputs.length; i++) {
            Mouse mouse;
            if (inputs[i].getType() == Controller.Type.MOUSE) {
                mouse = (Mouse) inputs[i];
                mice.add(mouse);
            }
        }
        System.out.println("Discovered " + mice.size() + " mice.");
    }

    public ArrayList<Mouse> getMice() {
        return mice;
    }
}

The information that is being printed out is always 0 for both x and y. I am running this on windows 10, does that cause any issues? How do I get the mouse data from the mouse using Jinput?

Answer 1

JInput is lower level, you are confusing a window pointer, and a mouse. The mouse is just a device with >2 relative axis. The values after each poll or in each event are not a number of pixels, or a position, it is just an offset in roughly abstract units from it's previous value. Some mice report larger values for the same amount of physical distance changed, so you have to scale it, which is why games that use the directx mouse (also a relative axis device) have a mouse scale slider.
