Question I know this is API for other plugins I see that awnser a ton. 
But I am asking is there any mods that you know of that is using economics and would allow you to convert to scrap what is earned? So that you can use scrap at the end currancy so that you can then allow players to convert and use that for buying stuff on the server. 

I was trying to find away that they can earn money and then use that to buy stuff for scrap on the server fromt he vending machines. 
What I was looking at is VendingManager with this and it would allow people to earn scrap as currancy and doing that would allow you to build a full market just off scrap in the game. 
Any ideas? I am open. I mean i guess I could use GUI Shop to do that but found it silly to use GUI shop just for converts.
