Multiple item cost?

[Doodman]

Hey there, im a complete noob at coding (hoping to change that soon) so ive just been making tiles for a new game

So to the point, i was wondering if there was a way to instead of having a certain item ( lets say a potion) from costing X amount of coins, have it like Potion A costs X coins, but also 3 rocks

or something like that
I need this because i was gonna make a kind of enchant/ upgrade system, where you take a sword, and some kinda upgrade stone and use them to buy the upgraded sword from some kinda shop.

If theres some kind of tutorial i would appreciate it greatly if you could supply the link.
And if not, just tell me in a kind of vague sense how i would do this, and then i can try and figure out the coding after ive learned a buttload of it ;D

You would need to code in an extra cost feature in the shop, etc.

There's an old tutorial for this that you will have to tweak to work. Try looking in the source tutorial part of the forums.
