Wait a minute I think I'm on to something but with a glitch.

This code below dose half of what I was looking for, it hides weapon only after I buy it and exit the weapon shoppe and then I enter back in to weapon shoppe, bought weapon is not active, I can even collect ammo and when exiting weapon shoppe I have to press 1-3 to bring the weapon in to actions.

Code it activated only when in contact with entity that has code load_level

Code:
switch(t_shooter_weapon)//
 {
 case 0://if its 0
  if (t_shooter_weapon == 0)// check if any weapons selected
  t_shooter_weapon = 0;  // no weapons equipped
   break;
 case 1://if its 1
  if (t_shooter_weapon == 1)// check if any weapons selected
  t_shooter_weapon = 0;  // if weapon selected do not equip in this level
   break;
 case 2://if its 2
  if (t_shooter_weapon == 2) // check if any weapons selected
  t_shooter_weapon = 0; //if weapon selected do not equip in this level
   break;
 case 3://if its 3
  if (t_shooter_weapon == 3) // check if any weapons selected
  t_shooter_weapon = 0;  //if weapon selected do not equip in this level
   break;
 }


Glitch is that I can still equip weapons in weapon shoppe level by pressing 1-3.

So my next question is how do I code this:

if key_pressed 1
ignore key_pressed 1 just for this level
