PDCurses getch not working as intended

[Guest]

Archived from groups: rec.games.roguelike.development (More info?)

No one replied to some of my previous, maybe they were eaten by server
or something... Anyway, everyone on Win98 seems to get this problem, yet
I was unable to find a solution. The problem is that getch() from
PDCurses seems to miss or get wrong values for most of keypresses. When
I try to move a PC in my project I need to press the same key 5 or more
times before the game reacts. NPCs move with each keypress. When I undef
getch (so the getch from conio.h is used) everything works as intended.
Is there a way around this bug? Cause it really drives me mad.

To anyone else who encountered this problem, here is the temporary fix
I've found. Instead of

c=getch();

write

c=getch(); if (c>=60928) c-=60928;

That's one weird bug...

Well, I learned the hard way that the constant "60928" above is random
for each session. Looks like some lazy programmer forgot to initialise
some counter... That's why I hate open source software. You don't even
know who to blame!

Anyway, the user would have to type "zzz" at the beginning of the game:
this will be enough to calculate the constant. If he types something
else... he is screwed!

You have to change the extension to something like *.ex_, or put it in a
zip file. Tripod prohibits download of executbles (you can mail me the
exe directly too ;-) ).

Damn that tripod! Now they don't even have a FTP access so I have to use
their clunky site to upload files. The game is not very playable btw, it
just demonstrates the engine

The new link is http://grue3.tripod.com/footie.zip

60928 = 0xEE00, from which I would guess that you're taking a char
return value and interpreting it as a short or long, and getting
leftover junk in the upper part of the register. The actual keycode it
gave you is 0 (null), which tends to show up in inputs a bunch of times
and should just be ignored.

The fact that this is happening suggests that you're using the library
from one version of curses and the header files from another;
ordinarily, the compiler would handle type conversion issues like that.

You were right that I used the old header file, but updating it didn't
help... The only chars used in my project are related to strings.
However you gave me a good idea: I'll do getch()%256.

My god, this is brilliant! :-D
I'm waiting eagerly for further result! Have you considered a
"BloodBowl" variant? I tried to kick a player to death but it didn't
work :-/

I'm trying to create a realistic simulation here You'll get sent off
for that and banned for the next few matches... But maybe there would be
a hidden option for increased violence

Anyway, thanks to everyone, I completely rewritten it under PDCurses and
it kinda works. Now I need to work on a gameplay.

Hmmm. Are you sure that the getch() you're calling is actually the
one included with pdcurses? I vaguely remember getch() being part of
some PC compiler's library. Maybe you're calling the wrong getch()
but using the prototype in the PDcurses include file.

Alternately, there could be some difference between the calling
conventions of your compiler and the one that compiled your library.
You might want to try building PDcurses from sources with the same
compiler you're using to write your roguelike. This will also make it
easier to step through PDcurses code with a debugger.

It's in conio.h and I noticed the older version of Mingw/GCC was
including that even without #include <conio.h>. I guess it was some
kind of automatic basic library include. When I compiled my project
with new Mingw I got lots of undefined errors, because there were
missing library includes.

As I wrote before, conio.h's getch _is_ working properly. I'm almost
sure it's system-dependent PDCurses bug as some people had the same
problem.

No, what you have here is a namespace conflict. Two libraries both
contain functions named 'getch'. The compiler uses the prototype in the
header file of one of those libraries. The linker uses the function
from the other library. In this case, getch will work only if the two
libraries happened to define getch with the same signature; otherwise
you have an undetected type error, which may produce exactly the
symptom you described at the top of this thread.

Are you, by any chance, compiling without warnings enabled? You need to
pass the -Wall option to the compiler. Also, make sure you are linking
with the pdcurses library properly (-lpdcurses option, after all the
object files), and including the right header files.

And if you're using the library with the conflicting getch as well as
pdcurses, put -lpdcurses *earlier* on the linker commandline than that
other library. The linker will then use the correct getch.

Cute.

Actually, I'm thinking some simple sports sims would be great in any
roguelike attempting to create a "living world" effect. And then, to
satisfy the combat monkeys, rioting fans afterwards!
