PhantomChess has been getting quite a few updates in recent weeks and it would be good to get feedback from others. It is a Python-based Chess game that has three modes of operations in Pythonista. It starts up in text-only mode where it takes commands on the interactive prompt. The gui command switches it into a ui/scene based gui mode. The sk command switches it into a ui/sk based gui mode for those who are running the Pythonista v1.6 beta.

To install Phantom, copy the text of Phantom_installer.py into a new Pythonista script window and run it. A local Phantom directory will be created with a Run_this.py file in it. To improve PhantomChess Please open issues or send pull requests.

@Saturn031000 This is a known bug for all system text input alerts in Pythonista, and is (I think) fixed in the current 1.6 beta.

That was indeed the issue. Thank you!

@JonB I import img_names in the main part of the file -- I'll shift it to be in the setup and load it into a list. Originally I had been using load_image_file but I thought I'd rule out the possibility it was that causing the problem so I switched to load_pil_image. I'm assuming load_image_file is faster and will switch back to that.

@ccc do you think it would be possible to load the images into a dictionary? I'd prefer not to use a list as that might end up needing exec or eval() neither of which are good. From the piece class itself (as youll be able to see shortly - I'm uploading the code today) I have the 'color' and 'ptype' attributres which respectivley represent the color and piece type eg. 'white' & 'pawn'. This would allow me to use a dictionary with keys like {'white_pawn': xxx, 'black_king': yyy} and I could use a loop to render the images something like:

for piece in self.game.board.pieces: img = self.images['{}_{}'.format(piece.color.color, piece.ptype)] scene.image(img, x, y)

as opposed to having to do something long and complicated with types of the piece etc.

Came up with my own solution after running into some problems with the get_remote_resources() method (the zip file kept getting corrupted in the download process): I loaded the images into Pythonista using a computer program called iFunBox and used the scene.load_image_file() function.

In the mean time, I have also completely restarted the project from scratch (but mostly just have the GUI left to do) so it'll be some time before it's uploaded.

Your should read up on numpy. Its all there and coded efficiently.

Thanks for the useful tool. Python is still relatively new to me and whenever learning a new language it always helps to spend as much time as possbile reading existing code. The Python standard library modules are ideal sources (pun intended) for code to study.

fmath.is_prime() is slowing you down...

I will post some replacement code on the gist.

The problem is that 1/2 evaluates to 0 because you're dividing two integers, if you use 1.0/2.0 instead, you should get the expected result (1./2 is actually enough).
