Thanks for trying to help me and have me understand arrays, but I just cant figure out how to unequip weapons with array.
I tried your method in many various ways and no luck.

To tell you the truth I do understand your method by using arrays, its my ability to code is very limited, there fore I try to go around pointers/arrays as much as possible until I get full sense of them.

The only way that I think can help me is to try and disable key 1,2 and 3 temporarily while player in weapon shoppe lvl.
To avoid being able to equip weapons in that specific level.
