ScrollableArea disable while touching

[wintermute]

Hello,

So I'm trying to code something like dragging an item out of a scrollable area. What I do is if I touch something in the scrollable area for more than 0.5 seconds, I disable the scrollable area and create a new "fake" object to drag around the screen. After releasing that object (touch up or mouse button up), I re-enable the scrollable area.

I think I've found a bug.

When a touch is active (i.e. i'm currently scrolling it) then I disable the tk2dScrollableArea script. The variable

Code: [Select]

isSwipeScrollingInProgress is still true. However on the

Code: [Select]

OnDisable() method, you unsubscribe to OnInputUpdate via

Code: [Select]

tk2dUIManager.Instance.OnInputUpdate -= BackgroundOverUpdate;
So next time I enable it it won't register to the to the line

Code: [Select]

tk2dUIManager.Instance.OnInputUpdate += BackgroundOverUpdate; in

Code: [Select]

BackgroundButtonDown()
So when I enabled it, it won't scroll anymore.

Is this a bug or is this intended behaviour? Please advise, thanks!

No, it isn't intended, but neither did we foresee anyone doing what you're using it for
Good find with the bug, and thanks for reporting it.

It should check for and clear both isBackgroundButtonDown and isSwipeScrollingInProgress, so it should read:

Code: [Select]

        if (isBackgroundButtonDown || isSwipeScrollingInProgress)
        {
            if (tk2dUIManager.Instance != null)
            {
                tk2dUIManager.Instance.OnInputUpdate -= BackgroundOverUpdate;
            }
            isBackgroundButtonDown = false;
            isSwipeScrollingInProgress = false;
        }

Applied your code fix, works now. Thank you!

Hi guys,

Sorry to hijack the thread slightly, but I was hoping you might help me on this one?


Any chance you could explain how you are doing the 'if pressed for more than 0.5 secs' part?

I'm a bit of a noob and I'm struggling.

Cheers!
