Hi, I’m trying to achieve an effect similar to the one in this video.

I already have my score system set up, as well as a bonus score for collecting over a certain amount of pickups. When the player completes the level, the score and the bonus are added together to reflect the new total, but they are added together instantly. I have all the maths sorted - so this question is purely related to the way in which the numbers are displayed when the math takes place.

How would I achieve the effect where the numbers are added together slowly ?

Hopefully I made this clear enough to understand.

Thank you.
