love.js standalone player

[ivan]

Thank you for the clarification. I will take a look at this issue when I have a chance.
The same fix is available for Apache as an .htaccess file.

Hi, I'm trying to pack the game for love.js and below you can find the errors that appear when I run the server which is done with python: python -m SimpleHTTPServer 8000

My game is here: https://codeberg.org/glitchapp/fish-fil ... llets-mini

Code: Select all

Failed to allocate internal command buffer.
WebGL context was lost. love.js:1:63325
Uncaught out of memory

After refreshing the website I receive the following errors:

I'm not sure what I'm doing wrong, any hints?

[ivan]

Based on the third error message, my question is: did you package and upload your .love file correctly? The "main.lua" file of your game should be in the top directory of the love/zip file. Furthermore, you can specify which .love file to run in the love.js player using the "g" parameter:

Code: Select all

https://example.com/lovejs_folder/?g=FishFilletsMini.love

The .love file must be in the same folder as the love.js standalone player.

[glitchapp]

It is in the same folder, I packaged the game with: python ../emscripten/tools/file_packager.py game.data --preload FishFilletsMini.love@/ --js-output=game.js

and there are no errors after that command.

The game is properly packaged because it runs when I double click on it.

Not sure if the errors below help:

Hello again. I know very little about Python servers.
You need to make sure the headers are set correctly as described below:

Apache
https://github.com/2dengine/love.js/blob/main/.htaccess

NGINX
viewtopic.php?p=249988#p249988

[gianmichele]

is this now in sync with love 11.4?
Thanks a lot for doing this btw!

[ivan]

@gianmichele
Yes, it should be compatible with 11.4 (at least in theory)

I only wrote the frontend for love.js, whereas the actual port is maintained by Davidobot.
The source code is released under the MIT License although I am considering switching to zLib in order to be better aligned with the other versions of Love2D.

I just rewrote the love.js player to use the Fetch API and to take advantage of more modern JavaScript features:
https://github.com/2dengine/love.js

We need to bring more attention to love.js so it can become a part of the official Love2D distribution.

[ivan]

Just pushed two significant fixes to GitHub:

- loaded files are cached based on the URI not just the package name
- fixed a module/import bug

[ivan]

Just pushed another update:

- love.js will now show the "nogame" screen if the loaded resource is not a valid ZIP archive

[milon]

We need to bring more attention to love.js so it can become a part of the official Love2D distribution.

That's an awesome idea! How do we do that? What's the actionable step(s) that forum users can take?
