Minetest 0.4.7-0.4.11 does not appear some numbers - Linux

[yullaw]

Hello gentlemen,

I have read that the game Minetest is powered by Irrlicht, so that's why I would like to report some objectionable bug.

Minetest supports other language than English and user can set his own language. The trouble is, that if the keyboard layout is non-US, example CS (Czech), we can not write some numbers for the new server setting, as following:

4 - (normally we need to press SHIFT+4 to get number 4) - but it behave like enter key.
7 - (normally we need to press SHIFT+7 to get number 7) - but it does nothing
01235689 - works well

The same reported bug here: https://github.com/minetest/minetest/issues/845

Informations:
======================================================================================
- Minetest 0.4.x(tested from 0.4.7)-0.4.11
- OS Linux (tested on Mageia 4 64bit, Ubuntu 14.04 64bit, Fedora 21 64bit) - everywhere it is the same
- no faults/errors in the terminal, just only:

Minetest can be launched with different language, example:

$ LANGUAGE=cs minetest

For more information or tests I can be assisted. Thank you for advice!

Hard to debug for us as we don't know the Minetest code and at least I don't have such a keyboard. Maybe as first step someone else can try if he can reproduce that generally with Irrlicht.

Which means - checking out Irrlicht svn (https://sourceforge.net/p/irrlicht/code/HEAD/tree/). Go into source/Irrlicht and run make.
Then checkout my tests (https://code.google.com/p/irr-playgroun ... e/checkout) and put them into irrlicht-code/examples so you get irrlicht-code/examples/irr-playground-micha. In that folder copy gui_font.cpp to main.cpp and run make. After that you have a small application called playground which I generally use for simple keyboard input tests. If it works there it's probably not an Irrlicht problem - if that also fails we'd have to figure out how to solve it.

@CuteAlien:

Thank you in advice!

Just the step:" In that folder copy gui_font.cpp to main.cpp" maybe is misunderstanding for me... Can you write more detailed step?

Summary: We can see the different between Irrlicht versions !

Wishing you happy new year 2015!

[yullaw]

FYI: The last post has been edited.

[yullaw]

I figured out that not only issue of numbers, but with keys "ěščřžýáíéůú)" as well.

This trouble is present in SuperTuxKart 0.8.1 too!

[yullaw]

Small workaround can be to change a keyboard layout to US by command as:

Code: Select all

 
$ setxkbmap us && ./minetest && setxkbmap cz
 

which will change a keyboard to US, launch the game and after closing will change to Czech keyboard back.

But we should launch the games without these commands... Should be nice to fix that.

[yullaw]

Do you have other solution or fix that, please? Or should I open a bugreport?

Thanks for reply!

[CuteAlien]

Sorry, had no time yet to investigate it further.

[CuteAlien]

Unfortunately not so easy to reproduce. I did several experiments:

When I switch keyboard layout with KDE then it just works in Irrlicht trunk (aka Irrlicht 1.9). No errors and I see the czech keys in the input field and get Irrlicht keycodes.
When doing the same in Irrlicht 1.8 I get some more problems - the numbers still work in the editbox, but I can't see the characters when I press number-keys without shift.

So I tried your trick with directly setting the keymap with setxkbmap. And indeed I get then some warnings that certain keys have no corresponding EKEY_CODE. But the editbox still works (with and without shift) and Irrlicht will just pass through the original x11 keycode so the keys can still be used in games as well. This all in Irrlicht trunk. But I noticed I get other keycodes than you. For example I get 488 for '4' (aka 0x01e8 which is XK_ccaron for X11). Which seems correct to me unlike the value you seem to get.

So I'm puzzled - why are you getting such stranger X11 keycodes? They just seem wrong, those are not the numbers X11 should return.

edit: Did another test on Ubuntu, but Irrlicht trunk works there as well.

[yullaw]

Thank you for your test and input! Just now I have tried a trunk version irrlicht 1.9 and it works there well. Now I or we have to wait for a new stable version 1.9 and then to push it to the Linux distribution (Mageia) as an update. Do you know when it can be stable irrlich 1.9 released? Or still a lot of bugs are remaining?

Or for next tests to compile Irrlicht 1.9 for the system and then launch the games to try, that everything works well. But I do not know, if the game must be recompiled too.

Thank you for the support, seems to be solved in ver. 1.9 already.

[CuteAlien]

I don't know when 1.9 will be out. Depends a lot on if we really merge ogl-es before that or if we do another 1.10 release for that. And as usual depends on how much time our day-jobs leave us for working on the engine.
