FOSS gamedev and creative worlds

firstly, i know there is a official topic for the requests but it never gets answered.

my request is for a tekkit like condenser in minetest. if you dont know what a condenser is then i will tell you

a condenser is based on the idea of equivalent exchange, this means that every item in the game holds a value and that value can be traded for another item that has more or less value, this means that if i put a mese crystal in a condenser and made dirt then i would get a lot of dirt but if i tried to make a mese crystal than it would take a lot of dirt to make one.

the ui is generally like this

(item you want to make) (the value of the item and how much points it is worth)

(slot)(slot)...............................
(slot)(slot)...............................
(slot)(slot)............................

top left: the item you want to reproduce

bottom: a chest like interface where you can put the items you want to exchange

top right: the points in the condenser, points allow you to exchange items, dirt might be worth 1 point and mese might be worth 1000!

i don't even know if this is possible, many thanks

It is certainly possible. The tricky part is just going to be to figure out what to do with items that you don't know about when you create the mod. How do you assign them a point value? Assume some default for unknown items, or simply don't allow them to be added to the inventory, or...?

i was wondering if there was anyway for the mod to read the rarity of a item if it naturally spawns, also some items may not be condensable, for example a tool.

This would help a lot with money mod systems. It could create a norm to prices. Also maybe don't depend on rarity for example say you have a rarre item on the surface but a equally rare one underground. The surface spawned one would cost more because of easier to get. Also stewlblocks don't spawn but are a pain to make. Dirt is cheaper than cobble cause you can dig with the hand but there is more cobble but it needs tools.
