I am making a map, in which you have a few arrows at the ready, and then when you are out of arrows you can drop your reload item and get your arrows restored. I have gotten this system working fine, however there is an exploit where I can shoot at a wall, reload, shoot at a wall, reload, shoot at a wall, reload, then I walk next to the wall, and now suddenly I have way more arrows at a time than I am supposed to, as I just gathered back my last 3 clips at the same time. Is there any way to test whenever I get too much arrows, like I can set a arrow limit, and if it goes over a redstone signal activates.

If someone knows how to do this in commands, or has a better solution to the problem, Id appreciate the help. However I do not really want to prevent arrows from being picked up, I just want to limit of how many you can pick up. So thats what I am going for.
