Recently I wanted to show the text "Bonus +10" in a game. This needed to scroll up from the bottom and scroll back down after a second.
To solve this issue I used Rex MoveTo plugin.

I have included a sample capx file to show how this works.
I found one needs to take into account the time it takes to move up. This is that although the text pops up as required to wait for that 1 second before the text is scrolled down once again one has to include the time it takes to scroll up roughly.
In the example it took nearly 1 second to scroll the text up and hence I added another second as waiting time before it moves down again.
I hope you enjoy it and find it useful.
Apologies if my explanation in English isn't perfect but I am not English native speaking.
The capx was also uploaded to the Scirra Arcade which can be found here
