mBlock 3.4.12 was built on the framework, utilizing the source code of Scratch 2.0 .
Despite being an older release, version 3.4.12 is highly regarded for its stability and specific feature set. mblock 3.4.12
When you click on the "Edit" menu and select , the stage window disappears and is replaced by a text code viewer. As students drag and drop graphical blocks on the left, they can immediately see the corresponding C++ syntax update on the right. This visual mapping strips away the intimidation factor of syntax rules, semicolons, and curly brackets, helping students learn text-based programming structure contextually. Why Educators Still Prefer Version 3.4.12 Over mBlock 5 mBlock 3
Enter Makeblock, a Chinese robotics company famous for the "Codey Rocky" and "MegaPi." They developed mBlock—a modified version of the Scratch 2.0 source code. As students drag and drop graphical blocks on

mBlock 3.4.12 is an older version of the graphical programming software, which was primarily used for programming robots and Arduino-compatible boards. It is important to note that mBlock 3.4.12 does not have a built-in "Report" generator
This version was a part of the 3.x lifecycle. While Makeblock never made the source code for 3.4.12 publicly available, the community has pieced together its context.
