How do I add leading zeros to a score?

I'm working on a scoring system and I want it to show 5 digits at all times, like 00020pts, and to add to that number each time the player increases their score, but I tried searching for it without much result. Should I use a specific object type, or is there an expression that can achieve that?

Any help is appreciated!

There is an expression called zeropad. You can use it in the event where you display your text like this:

+ System: Every tick -> Text: Set text to zeropad(Score,5)

So the first number in the zeropad expression can be a variable such as your score, and the second number is the number of places you want to display.
