Android Question Dart board

[Colin Evans]

Hi, I need to create a dart board, with four sections in each number (1-20 in standard dart board numbering), is this possible graphically?

 

[emexes]

Yes.

A simpler way might be to find some free stock clipart or similar eg:

or even reasonably-priced paid clipart might be the way to go, depending on how you value your time:

Lol I had to do a couple of nudges, away from VB towards B4X, and manually add Pane1 in the layout designer, but other than that, I'd call this a pass:

https://x.com/i/grok/share/OqSYpc8eEfH5LztmOgu6Ws9qg

using the b4j dialect of programming language BASIC,
and the B4XPages cross-platform framework,
please write code to draw a circular dartboard,
divided into twenty sectors,
numbered 1 to 20 but in usual dartboard sequence,
shaded alternately in red and green,
with each sector having double and triple zones (rings)
and a bullseye circle in the middle

B4XPath does not have .ArcTo method,
so please change that to approximate an arc using short (~1 degree ) line segments

Please use B4J Iif function instead of VB If function

The best option would be to use an image from the web, but the problem is:

what do you do with the image or the code-generated drawing? It should be "interactive," reacting to events, otherwise, it's just a "picture."

This is the junk.generated by Copilot (just to make a comparison between the two AIs)

I find this incredible. Ideally the board should be rotated nine degrees anticlockwise but I am sure that will be a no-brainer for Grok.

I tried Grok (different question) a moment ago.
If you don't log in with your account, it won't even give you the second answer; a message says it can't answer CURRENTLY! Very bad!

I tried with Copilot with this prompt. Had the same 9deg offset as others - but easy to fix

Prompt:
you know the layout of a normal dartboard. Can you produce the B4X code needed to draw it on a canvas. Colours not needed and it can just be monochrome to start with.

 

[Colin Evans]

Thanks for your replies, perhaps I should have been a bit more specific, I need it for b4a, it's for the game of killer, so the dart board has to have each of the twenty segments divided into four sections, not sure it's possible but thought I'd ask

 

[LucaMs]

So?

In any case, the "problems" will be the functionality, whether you use an image from web or one built by code.

Yeah, that's been happening a lot lately. But every time, I hit retry, and then it works. Admittedly, I've been logged in.

I assume either they're hitting some capacity limit during busy times, or it's a ploy to get people to upgrade to a paid login.

And what about this ?
Done with B4X and no AI !

Did you code this, and if you did could you share please

 

[klaus]

Did you code this

Of course, B4X only !
With B4XCanvas and BitmapCreator.

and if you did could you share please

Sure, i will post tomorrow afternoon, it still needs some time to finish it.

 

[BlueVision]

Perfect, as usual...

Attached the xDartboardDemo project and the xDartboard.b4xlib.
It is a B4XPages project and the dart board is a b4xlib library.
Clicking on the dart board raises an event returning the ring index and sector.

EDIT: The files have been removed. The latest files are HERE.

 

[Colin Evans]

Hi Klaus, thanks but I'm missing the xDartboardDemo project, I can only see the b4xlib file

 

[klaus]

Sorry.
Done.
