Hi,

I have prepared sb3 file using Scratch 3 in Raspberry Pi4.
How to open sb3 file in Presentation/Full Screen mode?
Also how to run this file when Pi is booting up?

Thanks & Regards

I wouldn't suggest signing your posts with your real first name, this is online after all.

you go into the editor and upload the file then you can press the fullscreen button. these instructions go into more detail

Hi,
Thanks for reply.
Actually there is command we can write in terminal for opening sb file which is created in scratch 1.4.
scratch presentation xxx.sb
and then scratch program open in presentation mode.

I have created file in scratch3 and I want to run it with presentation mode, with just entering the command as it was in Scratch1.4.
Any suggestion?

So what you want to do is open a Scratch project in fullscreen on a raspberry pi when it turns on. There isn't an easy way to do that with the Scratch 3 desktop, but you can get it to work by loading it from the Scratch website.

To open it automatically in fullscreen, the easiest way is to open it with Chromium. To make Chromium go fullscreen, you can either use the --kiosk flag or the --start-fullscreen flag. I would recommend --start-fullscreen because it will allow you to exit with the f11 button.

To get the project to go fullscreen, you can add /fullscreen or /embed to the end of the url.

Edit from future me: Creating the file in the following paragraph will cause parts of the UI to not load correctly. Deleting the autostart file should fix the issue. See this for more information.

To make the command run on startup, you'll want to add it to the LDXE autostart file. That will make it start right when you login, or if you have autologin turned on, after your pi finishes booting. Run nano to edit the file and type it in.

You might also need to enable wait for network on boot if it Chromium starts trying to load the page before your pi is connected. This isn't an issue for me, but it's possible something will make it slower for you.

nano /home/pi/.config/lxsession/LXDE-pi/autostart

Hi,
Thank you so much for detailed process.
This process is working correctly.

But the file which I have created in Scratch Desktop is having GPIO extensions used, and I am not able to open it with Scratch Online editor.
Hence not able to use above procedure on the file I have created.

Hence I am planning to shift to Scratch 1.4, as I have to make small demo only.
I am planning to use launch sb file with ‘scratch presentation’ command during startup.
