Hi all,

I have been spinning my wheels trying to figure out how to build an item quantity tracker into my item pickup function.

Essentially when the player picks up an item I want a number to appear in their inventory showing how many they have.

The issue is every time the item is picked up, the function runs and it creates a new text object on top of the other one so they just keep stacking and it gets all jumbled.

I tried destroying them and recreating it each time the item is picked up but it destroys the other item quantities.

Here is my current config:

And here is a link to my project file if you require more context: drive.google.com/file/d/1XcwPibvtKqQ79krFOU7Gy_eqV_tKZ90V/view

Thanks in advance!

If you are already using an array to store the items by name then you should use the array to store the amount, in the next row or column. Then you can compare using the array each time, find name and the amount is at the same position.

The logic in the function would become something like, array contains name, find co-ordinate of name. lets say co-ordinate is 3,0 - add 1 to 3,1 (amount stored in next column).
