Hook the mouse wheel event and stop it propagating further down the scenegraph

entity.mouseWheel(function (event, control) {
    // Mouse wheel with button
    console.log('Mouse wheel button: ' + event.button);
    console.log('Mouse wheel delta: ' + event.wheelDelta);

    // Stop the event propagating further down the scenegraph
    control.stopPropagation();

    // You can ALSO stop propagation without the control object
    // reference via the global reference:
    ige.input.stopPropagation();
});
