Though Scratch is designed for people totally new to programming, it can still be a challenging program to wield. Consisting of a script, paint, and sound editor, it has complexity to its structure. This tutorial is aimed toward individuals completely new to all programming and looking to understand the concepts of Scratch.

Projects are animations, stories, games — just about everything made in Scratch! The Scratch program is used to make Scratch projects, which can be shared to the world by the Scratch community. In other terms, a project is the created application that is run.

The Interface

The Scratch interface is divided into two sections: the project running environment and the project development. In the top-left of Scratch is the Stage, shown at the top of the image on the right. The Stage is where a Scratch project is physically run, so when one plays a game, the Stage is the window in which it is run. By default, the Scratch Cat is on the stage. The Scratch Cat is simply one of many sprites, or characters, buttons, etc. in a project. Characters are programmed to perform anything one wants! The flexibility of Scratch allows the creator to be imaginative and actually make the desired project. That is when programming comes in to place, as it "makes things do what they should".


Before getting more into the interface, the quickest way to understand how sprites are programmed in Scratch are by testing things out. Follow the steps below when the Scratch program is opened with a clean, new project.

1. Access this area of the Scratch program:


2. Select the blue "block" called move () steps, and drag it to the right.

3. Release the mouse to place the block; make sure the block is placed in the darker-grey, technically called the scripts area.

4. When done, click anywhere on the block except the white middle, and watch what happens to the Scratch Cat... it moves 10 steps!


5. Check out the other block categories and test out what each one does!

As shown above, blocks are the literal building "blocks" of a Scratch project. They have specific commands which function uniquely from one another. Some blocks can even fit inside other blocks, as shown below: 1. Assemble the following "script", or connection of blocks, by accessing the various blocks by color and category.

2. Assemble the blocks into this formation:

3. Grab the blue key sensing block that is still in the void.

4. Place the block into the hexagonal input area in the orange "if" block.

5. Click the Green Flag to run the project, and see what it does!

6. Unless you were holding down the space key, nothing should have happened. Why is that? Take a look at the script again; remember, a script is a connection or stack of blocks.

when gf clicked
if <key [space v] pressed?> then
move (10) steps

The script begins with "when green flag clicked", which was done. When the green flag is clicked, it triggers the script beginning with the "when green flag clicked" block to run. When the script ran, it first detects if the space key is down, and if it is, then the sprite will move 10 steps. Run the project again while holding the space key down, and the sprite will move 10 steps!

Paint/Sound Editors

Main article: Paint Editor
Main article: Sound Editor

Scratch even includes its very own paint editor and sound editor. A paint editor is a program used for designing and editing images. The Scratch paint editor can be used to draw the images for sprites (the characters, buttons, etc.). The sound editor is used for importing, recording, and modifying sounds used in a project. To access these two editors, click on the tabs above the blocks palette:


Sprites Pane

The sprites pane of a user's project. The currently selected sprite is highlighted blue.

Not all sprites do the same functions in a project, so different sprites have different appearances, scripts, and sounds stored in their data. Accessing different sprites can be done in the sprites pane, located below the stage. The currently selected sprite has a blue box around it always; by simply clicking on a different sprite, its data can be accessed. The sprites pane is shown in the image to the right.

Creating New Sprites

Most projects on Scratch have indeed more than one sprite. How can new sprites be created in Scratch? Underneath the Stage is four valuable buttons for creating a new sprite:

With these buttons, a new sprite can be imported as either a plain image or one that already has scripts. The buttons, going from left to right, do the following:

  • Opens a pre-built sprite library with many choices
  • Allows one to draw his or her own sprite in the paint editor
  • Opens a file explorer to allow one to upload an image from his or her computer
  • Turns on the computer webcam to take an image for a sprite


Main article: Remix

The Scratch Website is filled with many projects. Feel free, if you find any cool projects, to remix them. Follow these simple steps to do so.

  1. Press the "See Inside" button in the corner of the project.
  2. Edit the scripts inside of the project to make it your own.
  3. Press the orange remix button in the top-right corner.
  4. The edited project is yours!

What Now?

One possible way to advance a beginner's knowledge with Scratch is by playing around with it. Trying out different blocks, testing tools in the paint editor, and seeing all the nifty sound editor features can help one learn more about the program. Resources such as the Scratch forums and Scratch Wiki can be utilized as help when necessary. Creating many quality, hard-worked projects is arguably the best way to learn about Scratch.
