The User Interface is the design of the interface of the Scratch editor. It is designed to make coding easier for beginner programmers.
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. So tasks easy in high-level programming languages are sometimes tough 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.).
Structure
Scratch is a programming language. It is divided into multiple sprites, which act in a similar way to different characters. Each sprite has unique characteristics, such as costumes, size, position, effects, and private variables. Blocks are the pieces of code that run the project, and each sprite has its own blocks that are independent of other sprites' blocks. Sprites interact with each other on the Stage, and they can communicate with each other using broadcasts, variables, and sensing blocks.
Blocks form each sprite are displayed in the Code Area. They are structured into scripts, which are connected chains of blocks that run together. The Block Palette contains a list of all blocks, and is where blocks are dragged from. The blocks are arranged into ten different categories: Motion, Looks, Sound, Events, Control, Sensing, Operators, Variables, and My Blocks. Some blocks can move the sprite or change its looks, some interact with other sprites or the Stage, while others perform internal operations, such as mathematics or changing variables and lists.
Components
The User Interface consists of several sections which allow users to create and edit projects.
On the top right of the screen below the Navigation Bar, there are three buttons: Code, Costumes, and Sounds. The Code area allows one to build scripts that run the project, Costumes allow the user to change how the sprite looks using the Paint Editor, and Sounds uses the Sound Editor to edit sounds.
Code Tab
The code tab contains several sections that allow one to code and run scripts and sprites.
Block Palette
- Main article: Block Palette
The Block Palette is the area on the left of the screen when the Code button is opened. On the left, there is an area that contains the nine sections of blocks in Scratch. To the right of that, there is an area that contains blocks that can be dragged into the Scripts Area to make code.
Extensions Button
- Main article: Extensions
The extensions button is the blue button below the categories of the Block Palette. It allows the user to add extensions such as Pen, Text to Speech, and Video Sensing.
Code Area
- Main article: Code Area
The Code Area is the large empty space to the right of the Block Palette. It is an area for storing blocks that run the project. Blocks can be dragged from the Block Palette into the Scripts Area and arranged to form scripts. Each sprite has its own scripts, and sprites can be selected using the Sprite Pane.
Stage
- Main article: Stage
The stage is the area where the sprites are and perform their actions. It is located in the top of the area to the right of the Scripts Area.
Small Stage Layout
The small stage layout is a size option for the Stage. It lowers the stage's resolution to 240x180 pixels — half of the normal size, increasing the size of the Code Area, Paint Editor, and Sound Editor. The small stage layout can be activated by toggling the stage size switch located in the top-right corner in the project editor next to the full screen button. It is useful when using Scratch on a smaller screen or on a phone or tablet, as the Code Area may be too small to use on those devices.
Sprite Pane
- Main article: Sprite Pane
The Sprite Pane is located to the right of the Scripts Area and to the bottom of the stage. It allows one to quickly switch sprites and view the different scripts each sprite contains.
Backpack
- Main article: Backpack
The Backpack is a small area to the bottom of the Block Palette and the Scripts Area. It can be opened by clicking on it. It stores scripts, costumes, and sounds and allows them to be transferred from one project to another. This is especially useful if work from another project is being taken to use in ones own project.
Ribbon Bar
- Main article: Ribbon Bar
The ribbon bar is the blue bar at the top, which from left to right has:
- The Scratch logo that links to the Scratch Homepage
- A wireframe of a globe which has a list of languages
- File and edit menus
- Tutorials
- Project name, share button, and see project page
- Folder which links to My Stuff
- Profile picture and username
Paint Editor
- Main article: Paint Editor
The paint editor allows one to view, create, and edit a sprite's costumes.
Costume Pane
- Main article: Costume Pane
The costume pane is the area on the left of the paint editor. It allows one to switch between a sprite's Costumes.
Viewing Area
To the right of the Costume Pane is a large area to make edits and view the costume.
Tools
To the left of the Viewing Area are several tools that allow one to make edits: select, reshape, paintbrush, eraser, fill, text, line, circle, and rectangle.
To the top of the Viewing Area are more tools that include changing colors, undo and redo, grouping, layers, and flipping.
Sound Editor
- Main article: Sound Editor
The sound editor allows one to make, view, and edit the sprite's sounds.
Sounds Pane
The sounds pane allows one to switch between different sounds.
Viewing Area
The viewing area allows one to view the sound waves of the selected sound.
Sound Effects Tools
Above and below the viewing area are many tools. These include making the sound louder, softer, have effects, fade in or out, copying and pasting, undo, and redo.
Tools
Tools are the various functions that the interface has. They add functions on top of the main sections of the editor.
Stage Area
The following functions are found above the stage area:
- Green Flag - Starts the scripts in the project's code.
- Stop Sign - Stops all running scripts.
The following functions are found below the stage area:
- Sprite Rename - A textbox which can be used to rename the currently selected sprite.
- X and Y - Edits the position of the currently selected sprite.
- Show/Hide - Shows or hides the currently selected sprite.
- Size - Changes the size of the currently selected sprite.
- Direction - Changes the direction of the currently selected sprite.
The following functions are found on the navigation bar above the project editing area:
- Language - Change the language of the editor.
