    I’m learning Felgo and am experimenting with the RUBE example (flying penguin).  Could someone explain:

     

    1. Why is the background divided into 10 images of 700x700px?
    2. Why is the background divided into TOP images and BOTTOM images?  (overlapped to create cave)
    3. Why is the icicle background not aligned with the cave top and bottom (they start 100px+ to the right).  Is that something I have to consider in designing a background or is that just an error upon creating the demo?
    4. If I wanted a sprite for the Penguin, can I do that through RUBE?  If not, should I set NO image in rube for the penguin?  Do I add the sprint in Felgo QML code?

    Thanks!

    Trying to understand #3 above, and I realize the the background image centered on 0,0  which I assume is the center of the scene.  Does gameplay on a sidescroller start on the leftmost edge of the leftmost object of the scene – and scroll right?

    Yes I’ve gone through the tutorial – I actually have modified the demo in my in Qt Creator, and modified the world in RUBE.  However I’m not clear on the above concepts mentioned concepts.  Again:

    1. How do I get the game background (icicles)  left edge to align with the level left edge at start of game play?  I’ve tried to align them in RUBE but when the Felgo game starts the left edges are being misaligned.
    2. Is there a memory management benefit to 10 700x700px images as opposed to 1 7000x700px image?
    3. Is there a reason top and bottom images are separate for the level?  RUBE can trace two different fixtures in the same image file I believe.
