var ms: float = 0;

function Update() {
    if (Input.GetMouseButtonDown(0)) print("Left");

    if (Input.GetMouseButtonDown(1)) print("Right");

    if (Input.GetMouseButtonDown(2)) print("Middle");

    if (Input.GetAxis("Mouse ScrollWheel") < 0) {
        ms--;
        print(ms);
    } else if (Input.GetAxis("Mouse ScrollWheel") > 0) {
        ms++;
        print(ms);
    }
}

function OnGUI() {
    var e: Event = Event.current;
    if (e.isMouse) {
        print(e.delta);
    }
}
