Screenshot of Scratch 1.4's development environment at startup.

In designing Scratch, the Scratch Team's main priority was to make its language and development environment intuitive and easily learned by children who have had no previous programming experience. There is a strong contrast between the powerful multimedia functions and multi-threaded programming style and the rather limited scope of the Scratch programming language. Therefore, tasks easy in high-level programming languages are sometimes difficult in Scratch (e.g. multidimensional arrays) while tasks easy in Scratch are hard in many high-level programming languages (sprite-like graphics, sensing the ambient noise, etc.).

The user interface for the Scratch development environment divides the screen into several panes: on the left is the blocks palette; in the middle the current sprite info and scripts area; and on the right the stage and sprite list. The block palette has code fragments (called "blocks") that can be dragged onto the scripts area to make programs (called projects). To keep the palette from being too big, it is organized into 8 groups of blocks: Control, Motion, Looks, Sound, Pen, Sensing, Operators, and Variables. In version 1.4, the Numbers section was renamed to Operators. Its name was changed because of the addition of blocks that dealt with strings in that section.

Palettes and Panes

Scratch has a simple and easy to use interface. Its design allows users of all ages and experience levels to create projects. In order to do this, the program divides the different parts of Scratch into Palettes and Panes.

Block Palette

Main article: Block Palette

The block palette allows you to drag blocks into the Scripts Area.

Script Area

Main article: Scripts Area

Blocks from the Block Palette are dragged into the Scripts Area.

Sprite Header Pane

The Sprite Pane includes info about the selected sprite as well as a few tools for manipulating the sprite.

The Sprite Header Pane.
  • A sprite's name can be changed by clicking the box that contains the sprite's name.
  • The selected sprite can be manipulated by pressing one of the following buttons:
    • Lock — Lets you lock or unlock a sprite. Unlocking it makes the sprite draggable (no scripts necessary). Draggable Sprite Feature (1.4).png
    • Circular Arrow — Enables full rotation in a sprite.
    • Linear Arrow — Enables the sprite to only face left or right.
    • "-" — Disables Rotation. The sprite will remain facing 90 degrees no matter what.
  • Pressing and dragging the blue line located over the sprite will rotate the sprite.
  • Double clicking the sprite will return it to facing 90 degrees.
  • The sprite's X/Y coordinates as well as direction are listed.
  • If the pen is down, the color is shown.

Costume Pane

The Costume Pane contains a list of frames of the selected sprite.

  • It includes the name of the sprite and a preview image.
  • Clicking on frame will switch the sprite to the selected frame.
  • New costumes can be added to the list by pressing one of the following:
    • Paint — Opens the Paint Editor.
    • Import — A file browser is opened, allowing you to open a sprite file.
    • Camera — Opens a web cam or external device to take a picture for a new costume.
  • Costumes can be edited by pressing the "Edit" button next to a sprite. This opens up the Paint Editor.
  • A Costume can be copied by pressing the "Copy" button next to the costume. This creates an identical duplicate of the selected costume.
  • A Costume can be deleted by pressing the "X" button to the right of the costume
  • A Costume can be renamed by clicking the box in which the Costumes name is listed.
  • Right-clicking a costume opens a drop-down list with two options:
    • Turn into new Sprite — Turns the selected costume into a new sprite.
    • Export this Costume — Exports the selected costume to a new sprite file.
  • Costumes can be rearranged by dragging them into the appropriate order in the list.

Sounds Pane

The Sounds Pane contains a list of audio clips.

  • Includes the name of the sounds and a thumbnail of a speaker.
  • Clicking the speaker icon will play the sound.
  • A new sound can be added to the list by pressing one of the following:
    • Record — Opens the Sound Recorder. Audio can then be recorded from an external device.
    • Import — A file browser is opened, allowing you to open an audio file.
  • A sound can be played by pressing the "►" button next to the speaker icon.
  • A sound can be stopped by pressing the "■" button next to the speaker icon.
  • A sound can be deleted by pressing the "X" button to the right of the sound icon.
  • A sound can be renamed by clicking the box in which the sounds name is listed.
  • Right-clicking a sound icon offers a drop-down list with a single option:
    • Export this Sound — Exports the selected sound to a new audio file.
  • Sounds can be rearranged by dragging them into the appropriate order in the list.

Sprites Pane

The sprites pane contains a thumbnail view of all sprites.

    • Folder — Opens a file browser allowing you to open a sprite file.
    • "?" — Selects a random sprite from your files and opens it.
  • Clicking a sprite opens up either the Script Area, Costume Pane, or Sounds Pane.
  • Dragging a Costume to a different sprite will insert that Costume into that sprites Costume Pane.
  • Dragging a sound to a different sprite will copy the sound into that sprites Sounds Pane.
  • Dragging a sprite onto another sprite will swap their location in the sprite pane.
  • Right Clicking a sprite offers a drop-down list with four options:
    • Show — Shows the object (if hidden) and sends it to the front
    • Export this Sprite — Opens up a file browser, allowing you to save your sprite along with any scripts in the selected sprite.
    • Duplicate — Creates an identical copy of a sprite that includes scripts, costumes, and sounds..
    • Delete — Deletes the Sprite.
  • Hovering over a sprite will open up a tan box that includes the name of the sprite and the amount of scripts it contains. The box automatically closes when your mouse leaves the sprite.
  • Dragging a script from one sprite to another sprites thumbnail will copy the scripts to that sprite.

Stage

Main article: Stage
The Stage and Sprites Pane.

The Stage is a "sprite" that represents the background of its project. Because of this, it has special features that are different from other sprites. No sprites can move behind the Stage — the Stage is always at the back.

  • The stage has two buttons:
  • Right-clicking the Stage offers a drop-down list with two options:
    • Grab Screen Region for New Sprite — Allows you to select a rectangle. The selected area is then opened in the Paint Editor and becomes a new sprite.
    • Save Picture of Stage... — Takes a screenshot of the stage.
  • Sprites can be dragged on the stage.
  • All of the "action" takes place here!

Toolbar

The toolbar at the top of the program contains many very important functions in Scratch.

  • On the far left is the text "Scratch"
