Guess the Picture

Can you guess what these blurry pictures are before they are revealed?

In this project we will create a game where blurry pictures appear and slowly get clearer and clearer. The aim of the game is to guess what the picture is before it becomes completely clear!

Warning: Your screen size is quite small for viewing this. Rotate your device into landscape mode if you can.

Quiz

1 - Create a new Scratch project

Create a new Scratch project and delete the cat sprite.

Scratch: How to create a new project

Go to the Scratch website using the link below and click on the 'Create' link in the blue bar at the top.

By default, each new project starts with the cat sprite already added. To delete the cat click on the x in the blue circle beside the cat in the sprite list.

2 - Save and upload the picture sprite

Included with this step is a file called 'scgtp pictures.sprite3'. This is a sprite file that has three different costumes which are photos of a rhino, a melon and a bird.

Right click on the link and choose 'Save link as' to save it onto your computer (keep a note of what folder you save it into).

Then in Scratch, upload the sprite into your project as a new sprite.

Scratch: How to upload a sprite

You can upload images and sprite files into your project. To upload a sprite follow these steps:

First save the image or sprite file onto your computer. You do this by right clicking on the image or link and then selecting 'Save image/link as...'.
Choose a location on your computer such as your desktop and save the file.
In your Scratch project, put your mouse over the Choose a Sprite button.
Click on the 'Upload Sprite' button.
Go to the folder you saved your file.
Select the file and click 'Open'.

The new sprite will upload into your project and appear in the stage area.

3 - Create the lists

We will need two lists in this game, one list for the questions (e.g. "is it a rhino or elephant?") and one list for the answers (e.g "the answer is a rhino").

Create two lists:

one list called questions
one list called answers

Once you've created the lists, add the following code to setup the questions and answers. Note that the order of the questions matches the order of the answers.

when green flag clicked delete all of [questions v] add [elephant or rhino] to [questions v] add [melon or orange] to [questions v] add [bird or bee] to [questions v]

when green flag clicked delete all of [answers v] add [rhino] to [answers v] add [melon] to [answers v] add [bird] to [answers v]

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'.

4 - Create the picture variable

We will also need a variable to store which picture we are currently showing in the game.

Create a variable called picture.

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'.
