Crafting Recipes

Part of the Game Architecture in Unity section of Coddy's Unity journey. Lesson 63 of 64.

Challenge

Hard

Give CraftingBench its recipes.

Add serializable Ingredient (public item, amount) and Recipe (public result, List<Ingredient> needs), and a public List<Recipe> recipes.
In Start, recipeButtons[i] calls Craft(i).
public void Craft(int index): with every need held, remove them, add one result, log Crafted Axe.
Refresh makes a button clickable only while its recipe can be crafted.

Press Play and craft a raft. Then Check.
