How do I pick up one object?

I have created a bomb that will let you blow a wall to get to the next level. I can't seem to figure out how to pick up only one bomb. When I get into the game I have an infinite amount of bombs. I would really appreciate if someone could help me with this!

When you run your pick up code, try adding the "pick nearest/furthest" condition in bomb object, set it to "nearest" with the player object.

I made it so that when I colide with it an instance variable gets +1. and I want it so that when I use the bomb it goes down to 0 which I made. But I do not know how to cancel the conditions of the the instance variable is at 0. I might be a bit unclear but I'm trying to explain it as well as possible.

?

Is there any possible way to talk to someone via discord so I can explain it better?
