Help building Native standalone LÖVE games

Other observations:

  1. the love binary is very picky about library dependencies. Binaries built against one target may not work on a system of another version. Therefore it would be good to get the love build into chum, where all versions are available individually.
    I can do the “getting into Chum” thing, but I am not able to actually maintain or furher develop the code from @sashikknox and https://github.com/savegame/love/tree/sailfish. Someone else would have to do that and step up as a maintainer.
  2. Are there any apps/games out there that use libmodplug, i.e. .mod files for music? If not I would like to drop the dependency on libmodplug.

hi nephros, thanks for the help.
So if I follow your guidelines regarding the desktop files and add the ```

[X-Sailjail]
Permissions=Love2D

along with the internet permissions for those apps who need it and use the love directory for the app, we will have the main problem solved? Sounds great, I may not be able to edit and submit all at once but will do it little by little.

Regarding the other crash problems you mention which I can not reproduce:
I had to add sometimes tens of tweaks to the desktop versions of the game to make them work on my mobile, and all of them work, I would like to add more tweaks if needed but I don’t have other versions of sailfish to test and my sailfish virtual machine fails to start… therefore it is quite difficult for me to find out and solve those issues… I just can assure that on sailfish 3.4 32 bits on my phone all of the apps I submitted work…

I will at least follow your guidelines to solve the main problem.
Thanks!

  • regarding the error on blockdrop “Error: touchControls.lua:123: attempt to compare number with nil” , I initialized that variables and the problem should be gone now…

regarding the question about libmodplug… I don’t think any app need the library and if they do I can simply record the files and save it in a standard .ogg to reduce the complexity and problems with the dependencies.

#11

I hope. Start with the Screensaver one, that seems the easiest/most compatible according to my very brief test.

perfect, I may not be able to do it right now but it will be the first one I submit, thanks!

About crashes relating to mouse/joystick/touch etc, it may be related to:

#14

regarding the crashes relating to mouse/joystick/touch I have a possible solution that I will test later, basically I can assign a value when is nil to avoid it from crashing, I will test that later.
Regarding the screen saver, could you tell me if this is correct before I submit the app?

this is my spec file to build the rpm:

nephros I’ve just rebuilt the rpm and changed the directories to:

/usr/share/applications/springscreensaver.desktop
/usr/share/games/love/SpringScreensaver/springScreensaver-mobile-0.1.love
/usr/share/games/love/SpringScreensaver/springscreensaver.png

and added Permissions=Love2D;Internet
I don’t know if the .desktop file should be too on user/share/games/love/… but I tried that and it does not run on my phone that way. now it runs on my mobile, hopefully yours too.

#17

I’ve just uploaded another build of boxclip with some corrections regarding the issues with inputs and with the same path to install it as I did with the spring screensaver. I hope this time works.

#18

Hi, the .desktop looks fine (although I’d remove the name[de-de] part).

But. All the files were ok in the previous locarion.
Only the .love file needs to go into the new dir.

Maybe I wasn’t clear, sorry.

#19

right, I will then only change the .love files, do I need to reupload boxclip and spring screensaver or do already work?
I made corrections to both and also to blockdrop following your feedback. I can not reproduce the error on starphase and I have no idea what is causing it.

#20

Screensaver is fine, Boxclip misses the sailjail/permissions section.

These are the boxclip desktop and spec files:

I don’t know what else can I do to solve the sailjail permission problem.
It seems that I made a mistake with the desktop file on boxclip, I uploaded again and now it should have the sailjail permissions correct… hopefully…

#22

I’m a bit tight on time at the moment, but am willing to help on that front. I’m a bit behind on my duties, though!

Very cool,thank you.

I have submitted to testing, but have not set up a packaging repo.

Will you do a fork, or do we package at Chum git?

#24

Nitpicks:

The Name keys are duplicate, and the second one, Name=boxclip.desktop will lead to the name on the destop/launcher to be “boxclip.desktop”. So, remove that line.

You can place the Icon at /usr/share/games/love/, as long as you use the corresponding absolute path in the Icon key, but the more common localtion is /usr/share/icons/hicolor/NxN/apps with N being the resolution.
If the icon file is there, you can just use Icon=boxclip (no path, no extension, but case-sensitive) and the correct icon should be chosen.

#25

Which ever packaging repo makes sense and which I have access to :slight_smile: Where is it :slight_smile:

#26

Currently there is no git repo for packaging.

Love as I built it is now at
https://build.sailfishos.org/package/show/sailfishos:chum:testing/love2d

But contains a tarball of the tree at GitHub - savegame/love at sailfish, and my spec/yaml and the SJ permission file.

I can create a packaging repo at chum-git, and point the upstream git module to ?your fork of love?

#27

Hm, that sounds weird.
