Adding Snow to your PowerApp

I added 20 snowflakes to mine, hence so many variables. I used a timer (Timer1) and a toggle with variable “snow” to turn it off and on. Tweak to your needs.

Find a snowflake image and upload as media to your app

Add to App.OnStart

Add Timer1

OnTimerEnd

Set the Y axis so that
– If it’s now offscreen, go back to the top and give it a new X axis too
– If not, move down a bit
