hx
public override function onMouseWheel(deltaX:Float, deltaY:Float, deltaMode:MouseWheelMode) {
        fov -= deltaY;
        if (fov > 45.0) {
            fov = 45.0;
        }
        if (fov < 1.0) {
            fov = 1.0;
        }
    }

and im setting it here

hx
        createPerspectiveZO(proj, fov * Math.PI / 180, Application.current.window.width / Application.current.window.height, 0.1, 100.0);

but moving the mouse wheel doesn't have any visual effect
