Cycling inventory in the proper order, whether i have three or fifteen of the items

Might be a bit of a strange title, but hopefully gets the point across. Basically I have several weapon pickups spread around a map. I am working on a quick switch function which actually works right now if i have every weapon - the weapons cycle in a predictable order with each tap of the button; I cycle through all the pistols first, then all the smgs to all the ar’s, a rocket launcher, and so on.

However I want this order preserved if i have say three weapons instead of all of them. For example, if i go pick up the knife, the rocket launcher, and an AR, when i tap to switch from unarmed i want to go knife > AR > launcher

I’m storing the weapons in an enum array and switching on enum to get the current version working, but if i’m missing any weapons i have to tap through some “blanks” until i hit an array index i actually have. Anyway hope this makes sense. Thanks in advance for any advice, it is greatly appreciated!
