ScratchScripts

Unpacking a scratch project:

• inside a scratch project press File -> Save to your computer which should download a .sb3 file
• rename the .sb3 extension to .zip
• extract the newly renamed file like you would any other .zip file
• inside, you should see a json file, which contains variable, list and block data from your scratch project, and is what these programs use to load data into scratch

Uploading it back to scratch:

• After unpacking the .sb3 file, you have to re-compress it in order to upload it back to scratch.
• select all the files that were origonally unpacked from the .zip file along with your modified .json file
• compress them to a zip file
• rename the .zip extension to .sb3
• open a new scratch project and inside, press File -> Load from your computer
• upload your newly created .sb3 file
• if all goes well, the scratch project will load up and you will have some cool new things in your project.

Model3dScratchLoader:

a script for loading 3d model files (only .obj) into scratch json files.

Info:

• The program reads the .obj file provided in the variable MODEL_3D_NAME
• Next the program reads the json file provided in the variable JSON_FILE_NAME
• The program then loads all the data from the .obj file into 9 lists (defined in LIST_NAMES) (x, y, z)*3 for all 3 vertices of the triangles which should be found in the json file.

Important note:

the scratch project's 3d triangle data lists must be in the following order for the triangles to look right:

• x1 list
• y1 list
• x2 list
• y2 list
• z1 list
• z2 list
• z3 list
