Let me know if you need something explained better or more in-depth.With the Input element type, you can prompt the player to enter text or numbers - allowing for things like password puzzles. I tried to keep things on a simple enough level. To keep things extremely simple (but not very elegant), I would create methods for picking up items like so: public void PickupAxe(int slot) If (!slots.ContainsKey(slot)) // Nothing in this slot Then, when the player presses a button, I would call this method: private GameObject GetWeaponAtSlot(int slot) Sort of like so: private Dictionary slots I would use a list to hold the gameobjects (a more performant way) or a dictionary (perhaps more beginner-friendly) to hold the slot number and the weapon gameobjects. If one of those values is 2, you instantiate that object?

If I'm understanding you correctly, you have an update function somewhere that checks if Input.GetKeyDown(Ke圜ode.Alpha2) and then checks a bunch of values, like AxeValue, SwordValue, KnifeValue, and so on. I think you're going about this a little backwards.
