UMG Documentation for 4.4 Preview

You can also try using a timeline like in the screenshots below to animate since your basically just moving 1 of the variables so its easy enough. Can also easily add in curves way as well.

My Scoreboard is just a UMG Widget that is a Canvas with a Border as a child. The initial settings for it layout wise don’t really matter since you will be adjusting them in the Make Margin part of the Move Leaderboard Function. The key was when you want to move “Border” item your basically adjusting the Canvas Margin settings that the Border sits inside of and getting access to that was done weirdly (see the screenshot)

The Timeline is just a 0.6s long linear curve that goes from -300 to +100. The width of the widget is 300 so puts it off the screen at the start and then moves it over 0.6 seconds 100 units into the screen when it is done.

All of event graph is in the Level Blueprint just to make it easy to capture the Tab key which I use to open/close the scoreboard

NO idea if is the right way to do it but it works as you can see.
