TouchEvent getX getY (6 posts)

    I have the following problem.After implemented TouchListener, I want to select a Geometry with a single touch on the screen, and then, rotate the Geometry using TouchEvent parameter (getX() and getY() methods). Is it possible?

    Thanks in advance

    Thanks for your response, do you have a simple code example?

    Look at HelloPicking in the tutorials

    then instead of initializing your ray with the cam direction use the coordinates of the tap

    .....
        Vector2f coord = new Vector2f(event.getX(),event.getY());
        Vector3f origin = cam.getWorldCoordinates(coord, 0.0f);
        Vector3f direction = cam.getWorldCoordinates(coord, 0.3f);
        direction.subtractLocal(origin).normalizeLocal();
        Ray ray = new Ray(origin, direction);
.....
