scratch

Scratch is a graphical programming tool designed for teenagers aged 8 to 16 years old. It replaces complex syntax with colorful building blocks of code, allowing users to create interactive stories, animations and games through drag-and-drop combinations. It integrates logical thinking training and artistic expression, and relies on a global community sharing platform to inspire creativity. It is an iconic educational software that enlightens computational thinking and cultivates digital creation abilities. Friends who like scratch, come to Huajun Software Park to download and experience it!

scratch highlights

Low threshold, high ceiling: suitable for children over 5 years old, and can also meet the needs of advanced users (such as complex algorithms, physics engine simulation).

Cultivate comprehensive literacy: combine art, mathematics, and logic to promote interdisciplinary learning.

The community ecology is active: millions of users around the world share their works, creating an atmosphere of learning and mutual help.

scratch features

Graphical programming interface

Using the form of "building blocks" (such as motion, appearance, sound, control and other modules), users can complete the program logic by dragging and splicing the blocks, which is intuitive and easy to understand.

Supports real-time preview, code effects are immediately displayed, lowering the learning threshold.

Cross-platform compatibility

It provides online version (requires Internet connection) and offline version (supports Windows, macOS, Linux), which can be used without installation, making it convenient for creation in different scenarios.

Rich creative resources

Built-in character, background, and sound effects libraries allow users to directly call or customize materials.

Supports uploading local images and audio to expand creative possibilities.

Interactivity and sharing

Projects can be saved as .sb3 files for easy sharing and secondary editing.

The official community provides a global user work display platform where users can learn, imitate or collaborate to create.

scratch FAQ

How to save a project?

Online version: Click "File" → "Save to PC" to download as a .sb3 file.

Offline version: Automatically save to local, or manually export .sb3 files.

Note: Scratch 3.0 project files are incompatible with older versions (such as Scratch 2.0) and need to be upgraded through a conversion tool.

What should I do if the project file is lost or damaged?

Prevention: Regularly back up project files to the cloud (such as Google Drive, OneDrive).

Recovery: If the file is damaged, try to open the .sb3 file with a text editor, modify the possible error code (technical foundation is required), or download similar project modifications from the community.
