This is how I did it. Your millage may vary.
The character blueprint has the info for what shall be picked up, as in this case “Gem Pickup”.
The “Gem Count” is an integer I made up for it.
Over in the item blueprint, I have a new function called “Gems Picked Up”. This is where the counting comes from.
Not sure if this is exactly what your looking for, but it does what it should. I don’t have one that adds to a graphical counter, but this is the skeleton to get started.
