Linux issues. Please help

[Awfully Nice Studios]

Hello everyone,
This time a dev is asking help from gamers. ;)
Some Linux users are experiencing bad problems playing our game. The issue is that enemies are not spawning anymore.
The game is working fine though on our Ubuntu 15.04 machines. Now we are wondering what the difference is in those other configurations.
If you have this problem please report with your exact linux version and hardware configuration and how you play it. Notebook, Steam Link, Desktop and etc. Any info really could help us finding this issue.
Many thanks in advance

Is it a Unity game ?

If yes, it's probably due to a bug in old versions of Unity which have problem with some locale (decimal separator: comma vs point).

To fix it from user side, you have to set a specific launch option. Right click on game, select properties. In first tab, click on "Set Launch Options" and type this :

LANG=C %command%

I'm french (LANG=fr_FR.UTF-8, so with comma separator) and I need to do this trick for a lot of games with old versions of Unity. Newer versions seem to not have this bug anymore.

[Awfully Nice Studios]

Yes. It is a unity based game. Thanks for that trick. But our game is build with the latest version of unity. But i will let our players know to try this out. Thanks

[Drako Frost]

I confirm that using the "LANG=C %command%" as a launch option works. It needs further testing, but so far seems to have done the trick.

When Valve released CS:GO for Linux this launch option was also necessary, the issue doesn't happen exclusively with Unity games. It happens when the system uses other language besides english, I believe the issue is with languages that have accentuation. I speak portuguese, and the language does have accentuation.

Take a look at this :

You have to replace your float.Parse(yourString); functions in all your scripts by this one:

float.Parse (yourString,System.Globalization.CultureInfo.InvariantCulture.NumberFormat);

Same problem with another Unity game.

I'm not a dev myself but this may give you hints where to look for.

Maybe it's not related exclusively to Unity, but I only encountered this bug with this engine.

Thanks guys for your replies, very helpful.

Thanks, adding "LANG=C %command%" worked.

My system:

Ubuntu 15.10 x64 (system language = German)
Linux david-pc 4.2.0-25-generic #30-Ubuntu SMP Mon Jan 18 12:31:50 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Nvidia GeForce GTX 950 (driver version 358.16)
CPU AMD A8-6600K

[Awfully Nice Studios]

The "LANG=C %command%" seems to be working for most people having this issue. Unfortunately we weren't able to reproduce it on our linux machines but we hope that it's okay to leave it with that for now until we find a better solution.

[Nel]

If you want to reproduce, first you have to test what locales are available on your system:

locale -a

You'll see C, C.UTF-8, which are the bare minimum for every distros, and locales for your own language. Depending on distro policy, en_* and the likes are available or not.

To properly test your game with other locales, you need to install them.

For Debian Jessie, you just need to install one package

apt-get install locales-all

For Ubuntu 14.04, it's a bit tricky. You have to generate locales yourself.
For a specific locale as mine fr_FR.UTF-8

sudo locale-gen fr_FR.UTF-8

For a wide range of locales, as all fr_* for every french locales in every countries

sudo locale-gen fr

At this point you can test if a specific locale is properly installed.

LANG=fr_FR.UTF-8 locale

If everything is OK, you'll see LANG and LC_* stuff displayed properly, otherwise, you'll see "locale: Cannot set...".

Then test your game with this specific locale.

From steam with a specific launch option

LANG=fr_FR.UTF-8 %command%

Or inside a terminal in one line

LANG=fr_FR.UTF-8 ./yourgame

or if you want to keep it for the whole terminal session for debug, use export command

export LANG=fr_FR.UTF-8
./yourgame

This specific LANG environment variable will last until you close up the terminal.

Game crashes for me after the 'Awfully Nice' intro. The title screen music plays for half a second and then this gets output to the log:

Works for me.

That makes the game a tiiiiiiiiny bit more challenging and interesting :)

Hello, I am a user of Linux Mint 17.3. Unfortunately there is a bug in the game, at the moment when the ceiling should start to fall they are not monsters, and a few seconds before it disappears and the countdown.

[Awfully Nice Studios]

At this point we can only support Linux Ubuntu due to the limitation of the Game Engine we are using (Unity).

[AciD]

I can confirm that the 'no enemy spawning' bug was present on Kubuntu 16.04.

Using `LANG=C %command%` fixed it.

[A0_Pato_Salvaje]

Confirm this bug:
Ubuntu 16.04 (Unity) 64bits
Intel® Core™ i3-2350M CPU @ 2.30GHz × 4
Intel® Sandybridge Mobile Graphics
8GB RAM

"LANG=C %command%" fixed it

Maybe you have to advertise this in the frontpage for the Linux/SteamOS people... until you find a proper solution

There is a proper solution already given in post #4, 6 months ago, but they don't care.
Also look at CultureInfo Unity[lmgtfy.com]

They also claimed they couldn't reproduce this bug, so I wrote a step-by-step guide in post #8 on how to setup different locales and how to use them for Ubuntu and Debian/SteamOS, but they blatantly don't care as well.
