Here is where i have gotten to. It works but doesn't work. Basically, my goal is to be able to switch through weapons. Each time i switch currently i have to double tap. first tap equips and then second tap unequips. What i would like to do is have it so when i hit equip, if a weapon is already equipped, it unequips and then equips the next one. While cycling through the weapons, i currently have a bool setup on the weapon which tells this script wether its in the inventory or not, if its not in the inventory it should skip until the next available weapon. Once cycled through all the weapons, it would start back to the first, or last depending on which way your switching, ex: in the script already. You would be able to switch either - or +. I know its a lot to ask but if there's someone who can help with this quickly i will reward you with 20 points =]
