2 - Create the lists

In the Data palette, create 3 new lists by clicking the 'Make a List' button.

'Team 1' this will store the names of the players on Team 1
'Team 2' this will store the names of the players on Team 2
'Events' this will store the events that can happen in the match like a player scoring or someone missing.

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.

3 - Create the variables

We will need some variables to store values to help us run the game. Variables are things that we use to store some information such as the top score of a game or what level you're on.

In the Data palette, create 5 new variables by clicking the 'Make a Variable' button.

'team' this will store which team the next event will be for
'player' this will store which player from the team
'minute' this will store the current minute of the match
'score team 1' this will store the score for Team 1
'score team 2' this will store the score for Team 2

Scratch: How to create a variable

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

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

4 - Add a referee sprite

We're going to use a referee sprite to call out the events that happen in the match. Add the Referee sprite from the sprite library and then drag the referee into the middle of the stage area.

Scratch: How to add a sprite from the library

To add a sprite from the sprite library follow these steps:

Put your mouse over the Choose a Sprite button
Click on the magnifying glass
Find the sprite you want in the library
Click on your chosen sprite

You can use search box or the filter links (Animals, People, Fantasy etc) to locate your sprite.
