Thank you guys!
Are there any templates or an app that I could look at?
If I were the company making this product, I would release a few different apps that showcase these features and how they think you would implement them.
I couldn't find any documentation, about the widgets etc. that exist for the PaperS3. Is there no such thing as proper documentation for the different blocks and how they are supposed to be used?
I agree that with what I have on hand, trying to use a rectangle with the coordinates would be the way to go. Unfortunately, it's not obvious to me how to go about this. Even with the few things I managed to do, I retro-engineered from another app.
