How to detect a vertical swipe from up to down?

I want to fire a function whenever a person swipes from down to up. Any answer or even a hint would be appreciated.

You’d need to use a canvas and the “When Canvas flung” block.

Up is 90 degrees, Down is 270.

So you could check for a swipe between 45 and 135 for an Up direction (or make it tighter if you want),

Down you would check for a swipe between 235 and 315 degrees (or tighter).

See here.


I can’t use canvas in my condition. I want to detect it on a layout arrangement.
Is there any other way to detect a swipe ( on a layout ) ??

well… still thanks for your reply.
