How to put crafting?

I wanna put crafting into the game im creating, so people can collect regents and create their own potions or cook their own food. Is there already a way to do that with the software, or do i need some kind of script?

Heres a list of stuff i want to do:

• Alchemy, so people can create their own (weaker) healing potions and buff potions
• Cooking, so people can create their own healing food
• Blacksmithing, so people can reinforce (buff/enchant) their armor

Is this all doable through the software i have as it is, or would i need to get a script of some kind? Im not asking for script help, im just asking if i could possible do this with or without a script

There are a few scripts out there for this. As far as doing it without, I am not 100% sure.

here is a link to the main/most popular one out there if you want to take a look at it.

If you make crafting only possible at a certain spot - say cooking needs a stove, then you should be able to event the stove to take care of all the 'crafting' stuff: check for items in the characters inventory, variable for actor's skill, and out pops the cookies.

So a campfire would be all i would need for "cooking"? hmmm i actually have some ideas now without a script....thanks a bunch :)
