I know in farmchain you have to have multiple things to purchase a plant. (Water, the seed, and energy.) Do we have access to a multiple item purchase like that?
In vending machines it seems like we can only choose 1 item for payment. Is there a work around for this other than, having a progression of vending machines where you have to do it all 1 at a time?
Add a vending machine, and set it to purchase at whatever cost you want. Then, add a checker, and set it so all checks have to pass. Set the checks to be greater than an amount of the certain items. Wire a button to the checker, and the checker to the vending machine, so if all checks pass, you get the item.
I think that would work, but before I go through testing this, it seems to me that I could pass the checks without having to spend any of it. This would allow players to just spam the vending machine without having to truly spend the requisite resources.
