I got into the code to see if maybe I could write a script for this and I tried everything, but I could not get it to work. In the code source it has "quantity" "weaponammo" "weaponammoclip". I tried "quantity", but that will not allow that plr to pick it up. Something else was the ability like health to be able to check it to limit it and I saw it in the code, but the script would not run it.
So, my thought is I would see if you can get a mod that will do this or if lee makes his way through the forums to maybe include this Idea in the next upgrade.
Mods if you can I would change his post to "ammo limit" So that we can all reference this later. Thanks and I hope this helps you all.
