[1.6.x - 1.8.x] Advanced Vending Machine (v.2.0.1)

This machine is out of date. Check out the newest version here!

Hello everybody! Thank you for taking the time to read this. Currently, this is version 2.0.1 of this type of vending machine and I'm afraid it is impossible to add new features. I like my work to be the best it can be, and I'm always striving to make it better. This is why I am envisioning a new vending machine, but one that acts more like a vending machine. It won't be easy—I'll say, but I can give it a shot and see how it works. As of now, I am planning add the following to it while keeping all of the current features:

• Variable costs for items
• Memory device which keeps track of the current balance of the machine
• Device which costs an extra nugget to cook the item for you (with the inability to do so for non-cookable items)
• Shorter wait times (every item waits an equal amount of time)
• When item is out of stock, the button press will not work until restocked
• Easier item restocking
• More choices

Unfortunately, I haven't been working on this, so I don't think it'll be done anytime soon.

Current vending machine details below.

I've made a new vending machine.
It's pretty complex. It's not one that you hook up to a dropper and press a button.
I've seen many on YouTube, but I have yet to see one like mine.

It features:

• Working stock lights (will turn off when out of stock)
  
• Payment system which only accepts a certain item
  
• Ten choices
  
• Waiting light
  
• Anti-cheat system (guaranteed 99% cheat proof)
  
• Functional payment refund
  
• Command blocks
  
• Note blocks
  
• New functions added
  
• 95% bug-free!
  
• Now aesthetically appealing!
  

I hope you guys enjoy it. I'll accept all feedback both positive and negative.
If you think something could be improved, do let me know.
