I'm looking for a way to get the XML (or another way/structure) from a sequence of blocks used on my workspace inside Scratch-MIT 3.0 to display this code in the Blockly Google's library.
Right now I have access to the Abstract Syntax Tree generated by the scratch-vm component (https://github.com/LLK/scratch-vm), but I don't see a way to "rebuild" the code represented on this right on my workspace.
Is Scratch rendering the code from the Abstract Syntax tree structure or what? And how?

QUESTION
The default resolution of the Stage in MIT Scratch is 480x360 in a 4:3 aspect ratio. I want to change it to a 16:9 aspect ratio, with a 720p resolution. Is there any source file or script that has to be edited in order to do this?
Also, I found this link: https://scratch.mit.edu/discuss/topic/52369/ but I cannot understand how to do so. Here is a source file from that link: https://github.com/LLK/scratch-flash/blob/053d2b2eaf172ed2889211f5f57621731183f5c1/src/scratch/ScratchObj.as (Go to the line #51 to see the width and height of the stage: https://github.com/LLK/scratch-flash/blob/053d2b2eaf172ed2889211f5f57621731183f5c1/src/scratch/ScratchObj.as#L51 ) How to edit that source file, and then how would I compile it? Whenever I open that ActionScript file, It opens in Adobe Animate CC with black text on a black background (which I can't read).
Can anyone give me the step-by-step instructions to do that?
...ANSWER
Answered 2018-Sep-10 at 13:20Hey!
Compiling scratch from source would be a lot of work, there are better ways for this.
I think there are two efficient ways to solve that problem:
- You can embed the project into a website, using the following snippet:
Change the height and width of the snippet like you want. This only works, when your project is published.
Replace [Project ID]
with the id at the end of the URL when opening the editor in Scratch.
(Example: https://scratch.mit.edu/projects/12345678/#editor
-> Change [Project ID]
to 12345678
)

Install llk
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
