FOSS gamedev and creative worlds

I am changing all, the crafting ways in default, Since I liked to change them up, plus I going to make some new items so yeah I be busy, and since I am very new to Lua it may take me sometime understand all, the coding.

And I kind of understand some of it though.

So, what you wanna do?

Is this going to be like where at the crafting grid, you simply select an output item and only craft it if you have the items needed to craft it, and the items needed are taken from the inventory when it is crafted? That would be awesome.
