QR Code Generator

jirfeww

Oh hi. I have been here, and I want to know how to make a QR code generator. How do you do it?

Good question… I have no idea

By the way why do you want qr generator

xD search it up

If I could make a polite recommendation, you might want to start with something a bit more simple. Can you make a program that mocks up what you're trying to do without generating a unique QR code each time? Or provide a code in letters and numbers that might be easier to bring in to your program?

I'm pretty sure that what you're proposing is technically possible in Scratch… but ‘technically possible’ is a long way from ‘easy and fun’. You would have to look up and implement the QR standard, make your own from some combination of clones and sprites, then test it extensively to be sure that it actually works when scanned by a phone camera app… some of which have subtle or undocumented bugs. And… even if you were able to complete these tasks, Scratch is not designed or optimized to process incoming web traffic beyond ‘visit this URL’.

I love the ambition… let's aim it in a way that will probably be more successful. I'll be following your account to see what you are able to build next.

Well, so they can send secrets to people that can scan the QR Code!

I want them to be able to make secrets so no one can interrupt someone's IMPORTANT SECRET CONVERSATION! :: sensing

Those are against the rules, therefore you cannot make this project.

Chat Projects are against the Community Guidlines!

And how would that work? If I produce a QR code how does someone else see it? That's key to whether this would be allowed or not.

If you save the code in Scratch so others can read it that will be against the rules. There's no difference between that and a chat project - it's just a different form on encoding after all.

If they copy the QR code into an email or something that has nothing to do with Scratch - there are lots of QR code generators online so this is already possible.

that should give you some ideas

No, not chat, something like encoding the message and then someone scans it with a QR Code reader, and that.

It is probably possible to encode it but you would have to build the decoder app as a conventional reader is much more complex.
I would recommend having a 100 by 100 grid and highlight pixels if something is true.

Oh well, it looks like i will have to make an encoding thing first not qr code generator

Still need to watch the rules though, no free chat however you encode it.

But if it was just an encryption tool and a decryption tool that wouldn't break the rules though would it?

The QR code generator is most likely against the rules.

This shows you how they work.

I've already answered this. If you allow free text to be encoded and shared with others then that is a chat project and it doesn't matter how the encoding is being done - it is against the rules. If someone produces an encoded message and shares it via email or other platform there should be no problem them using a Scratch project to decode the message.

However if someone did that and wrote something offensive to the other person that may be a grey area. Your project would have enabled that to happen after all. So it would still be safer to only allow a pre-defined set of messages.
