To switch between two formats of an app

[numerist]

I'm not a coder, although I can understand some js and adjust some of it. I've altered the code of a bangle.js 2 clock face app written for me, in order to produce a second format for it. Because the two formats are together in the code, I have to comment out one to run the other.

On the touchscreen I'm already using horizontal swipes and touch left and touch right for changes to the display. I want to enable the user to also choose which format. What's the easiest mechanism for me to insert into the code for that purpose? If it's menu or submenu items to create Face 1 and Face 2, that's fine, but I'd need a good, unabbreviated reference to how to create those and make them function in the code.

Maybe you could use vertical swipes to change format? Since you only use horizontal swipes currently.

Or maybe implement the two formats as separate apps if they are somewhat distinct from eachother?

I suspect you need to trigger a redraw of the screen contents after updating the baseDate. So if you have a relevant draw function, add that directly after those if-statements in the code example above.

You could also add print(baseDate) there to verify in the output that the variable is updated.

The print(baseDate) shows that the base date does indeed change. I'll look for a draw function to place as you suggested.

There are a few things besides the base date to change on the tapping; I'll try to figure out how to handle those so that I don't have to redraw the screen many times. It would be good if the base date changed first and I could then specify the other changes depending on what the base date was set at after the tapping.

It seems that the swipe up and down doesn't work properly, and the twist function, which I'm using to unlock the screen, is always interpreted as a tap. With the double tap true or false, one twist is interpreted as one tap, two twists as two taps. I need another way to unlock the screen, perhaps, although the twist is very convenient.

At present I need to find a place in the code to put the double tap condition (it seems the best option) so that it does change the screen display (rather than redrawing the screen after updating baseDate, because that may be overridden later).
