2 - Create a 'shopping' list

Create a new list called 'shopping list', this will store the items on our shopping list.

When you create your first list you will notice that new blocks for lists become available to use in the Data palette.

At the start, when you click the green flag, we want the shopping list to be empty and also to be hidden (as we're going to get a character to read out what's on the list). Add the following code:

when green flag clicked hide list [shopping v] delete all of [shopping v]

The delete all of [shopping] block deletes all of the items that are in the shopping list. We do this at the start as there may be some items in the list from the previous game.

Scratch: How to create a list

In the Variables palette, create a new variable by clicking the 'Make a List' button.

Once you click this button a box will appear asking what you want to call your list. Give it a name that reminds you what you will be using it for. For example, if you wanted to keep track of top scores in a game, you would create a list called 'top scores'.

👇 Mark your steps as done as you complete them.
