Is there no way to programmatically exit a game?

[drako0812]

I like the idea of this package. But I've been struggling to find a clean way to exit a game do to input, besides just clicking the X button on the window. I would like to be able to close the game in reaction to user input. os.Exit isn't a good solution because it just immediately exits the program without any Go cleanup being ran. I noticed that Ebitengine allows you to return and error from the Update function to signal that the game should exit, I feel like it would be preferable to do the same with pi. But if there is an obvious solution that I missed, please let me know.

Hello @drako0812 ,

That's a good point :) At the moment there is no way to stop the game loop, otherwise than closing the window by the user.

I propose to add a new function which will be used to stop the game loop. Not yet decided in which package, though. Propably in piloop. Something like piloop.Stop(). And it will publish an event, which will be handled by backend, which will eventually stop the game loop and pi.Run() call will end. Then the game programmer, could add a logic just after pi.Run which will do a cleanup. What do you think?

I like that idea. Really any option is better than none in my opinion.

Good :) Then I'm going to add some draft PR in the evening.
