I do something like the count up effect in my "World Of Mineshaft" game. When you get a gold nugget, you hear a pick hitting as it counts up 100 at a time until it reaches the total amount you picked up.
I have two variables, one is what the counter shows, and one is what the total is. When the game adds points they are added to the total. Every .15 seconds the two are checked and if they are not the same, 100 (or total amount if less) is added to the counter, and the sound is played and a particle is spawned so it's more obvious where the sound is coming from.
Since it checks every .15 seconds, it's automated. It clinks, counting up to the total, where it then waits for the total to change again.
