Adding a Potion
Part of the Fundamentals section of Coddy's Lua journey — lesson 78 of 90.
Challenge
EasyBuilding on your empty inventory table from the previous lesson, create your first magical potion and add it to the shop's inventory. Create a dictionary-style table named healthPotion with the following properties:
namewith the value"Health Potion"pricewith the value15stockwith the value8
After creating the potion table, use table.insert() to add the healthPotion table as the first element in your inventory table. This creates a nested table structure where your inventory contains potion tables.
Finally, print the length of the inventory table to confirm that one potion has been successfully added to your shop.
Try it yourself
-- TODO: Write your code here
inventory = {}
-- Print the length of the inventory table
