Possible Mirrored/Flipped Bug

  • Problem Description

    Discovered that when a sprite is mirrored, if you increase the sprite's width, it does the opposite, and vice-versa. Didn't see this behavior documented anywhere, and causes me to have to do a workaround. I haven't checked it for flipped, but I suspect similar results.

    Attach a Capx

    Done.

    Description of Capx

    Two instanced sprites are presented. The one on the right is mirrored at the start of layout. Hitting right arrow increments width property of both sprites. Left arrow decrements width on both sprites.

    Steps to Reproduce Bug

    • Step 1 Load and run .capx file.
    • Step 2 Mash left and right arrows to observe inverted width behavior.
    • Step 3 Post reply!

    Observed Result

    Non mirrored sprite gets wider as width property increases, mirrored sprite does the opposite.

    Expected Result

    Both sprites increase or decrease width the same, regardless of whether mirrored is set or not.

  • I believe that this is deliberate. When a sprite is mirrored, the width is flipped, and negative, so only decreasing width will actually make the sprite larger.

  • DatapawWolf What would be the reason/logic for that? What purpose would it serve? If it's deliberate, why is it not documented?

  • Yttermayn I have absolutely no idea why. That being said, it has been around for a long time, so maybe Ashley can clarify why it is the way it is.

  • That pretty much is the definition of mirrored. Its just that Ashley made an action "mirrored" that does the work for you.

    If you don't believe me try it yourself, add a - to a sprites width.

  • Closing as by design: a mirrored sprite just has a negated width. Display the width values of each instance and you'll see how it works.

  • Ok, thanks!
