Trouble trying to get started with pygame

[René Dudfield]

Hi,

it's possible to have multiple processes running with separate pygame
windows.

However you need to communicate with an inter process mechanism.
For example by running a web server over TCP/ip/sockets, or UDP with OSC,
or shared memory with mmap, or even via clipboard copy/paste, the humble
file, or a database (Sqlite, PostgreSQL).
Each method has different trade offs.

However with pygame > pygame version 2 it is possible to have multiple OS
windows controlled by a single process.

The reason SDL and pygame do this is they come from a world where taking
over the whole screen (and OS) was common.
Also having multiple windows is mostly bad UX. If people are paying for
your UX, then probably you want good UX.

Note, that you can split the screen up inside a single OS window.
In pygame this is done easily with a subsurface, or by manually positioning
things with rects.


cheerio,
