Connect / Disconnect

Clicking the “Connect” button will connect R+ Scratch with the Controller and allow you to use the “Extension Block” in Scratch2Offline.
If Scratch2Offline and R+ Scratch are properly communicating, the O icon above the “Extension Block” will change from red to green in Scratch2Offline.

New Scratch

If Scratch2Offline is installed, clicking on the “New Scratch” button will load a new Scratch project that includes the blocks relevant for programming the selected Controller in Scratch2Offline.
You will first need to save the Scratch project before it loads in Scratch2Offline.
If Scratch2Offline is not installed, clicking on the “New Scratch” button will link to the Scratch2Offline download page. See Install Scratch 2.0 Offline section.

Open Scratch

If Scratch2Offline is installed, clicking on the “Open Scratch” button will load the list of provided example projects for the selected Controller. Double click on example project from the list to load that project.
You will first need to save the Scratch project before it loads in Scratch2Offline.

Help Menu

Clicking the “Help” button will load a folder containing help files.
Files named after the relevant Controller contain descriptions of the blocks used to program that Controller. Files with a *.json extension can be used when directly adding “Extension Blocks” in Scratch2Offline. See Directly Adding an Extension Block in the Miscellaneous (link) section.
