Pelúsica: a game, the survival of a musical ball

[VitoVan]

Hey fellas, I made a game in Lisp, initially it only works as binaries in desktop OS, now with JSCL, I finally made it work in the browser!

Have a try:

https://vitovan.com/pelusica/0.0.4/calm.html

It still feels a little laggy in the web browser, so if you really want to have a good experience, you should try the desktop version.

Here is the source code:

Hey!
jscl + wasm - great job
but something went wrong
look (Chrome Version 102.0.5005.115 (Official Build) (64-bit)) :

[VitoVan]

Uh... It looks like I have to install Google Chrome to test this out...

Thanks for your feedback! By the way, may I know the type of your operating system?

[VitoVan]

Just tried Google Chrome 113 on Windows, it seems worked, trying to find a way to download Google Chrome 102

Or maybe I should compile a version with -sASSEETIONS as told by the RuntimeError.

[VitoVan]

Just found the exact version of Google Chrome (Chrome/102.0.5005.115), and it worked 🤦

Ah, browsers, this is weird.

It seems like on your device the cairo_surface_set_device_scale function failed:

https://gitlab.freedesktop.org/cairo/cairo/-/blob/master/src/cairo-surface.c#L1824

And those cairo guys said this shouldn't fail "... unless given pathological input".

Sir, are you using an extremely expensive monitor with extremely high resolution? like pathologically high?

monitor with extremely high resolution?

Windows 10, Home edition, 21H2
Monitor resolution 1920x1080, nothing special
Ups! Video card NVIDIA GTX. I have a couple of thoughts, but I'll try it only tomorrow evening.

calm.js:formatted:487 Aborted(Assertion failed: status == CAIRO_STATUS_SUCCESS, at: ../src/cairo-surface.c,1825,cairo_surface_set_device_scale)

now curretn device scale 175%

[VitoVan]

Thanks!

I will try this setup once I got time, I guess it might be because of the device scale, which might lead to a weird cairo_x/y_multipler with my shitty C code:

[VitoVan]

Just tried the same setup, it depressed me. I am sorry for this.

It doesn't feel particularly slow in the browser for me. Good job!

[VitoVan]

🙇 Thanks for letting me know it also worked in your browser! 😮‍💨

That is really cool! thanks for sharing!

Thank you for creating JSCL!
