Theme: Scratch Art and Animation


These are the projects we built so far:

Digital Art 

This project was demonstrated by the tutor. It is a fun interactive art project that uses sound as an input. The level of the sound that the computer microphone detects, controls the direction, speed and sprite (object) colour.

Taking inspiration from the tutor’s project we built a simpler interactive art project that uses key presses as input. We control our art project with the following keys: up arrow, down arrow, space key and ‘c’ key.

This was a great project to play around with variables. We use variables to store data, e.g. a number. In this project we create a variable called “Fun” and we can increase or decrease its value by pressing the up or down arrow keys.

Click on the blue ‘See Inside’ button in the top right corner of the screen to see the code that was used to build the project.

We learn to:

  • Use key presses as user inputs
  • Use a variable to store a number
  • Use the variable to control sprite sizes and movement


Auto sprite stamp 

In this week’s project we use the arrow keys to control the sprite’s (object) size. We also automate the sprite to stamp every 1 second, change colour and use sound effects.

We learn to:

  • Use key presses as user inputs
  • Repeat actions forever
  • Use a timing device
  • Change colour effects
  • Add sound effects

Catch the Gobo 

The player tries to catch the alien to score points.

We learn to:

  • Use random XY coordinates with a random number generator
  • Use a variable to keep score
  • Create a speech bubble for our sprite
  • Use a forever loop

My Paint 

We recreate a simple paint project. We build colour blocks that allow us to change the colour of the pen. We also use the space key to put the pen down and up, i.e. switch it on and off.

The colour blocks act as buttons which tell the pencil sprite what colour pen to use. To make this happen, we learn about broadcast blocks. Broadcast blocks allow one sprite to send a message to another sprite and trigger an action.

We learn to:

  • Use key presses as user inputs
  • Create buttons that result in actions
  • Broadcast messages between sprites, which trigger actions
