The function wrapped the standard putchar(), doing nothing beside
discarding the return value. That could cause problems with tputs(),
which expects an int to be returned.
In some games, restore() passes the result of ctime() to mvprintw() or
some other variadic message-formatting function. If ctime() has not
been declared properly, its return type is inferred to be int instead
of char *. This does not cause a warning because the compiler does not
know the correct type of variadic arguments.
On platforms where ints and pointers are not the same size, this can,
probably depending on alignment, result in a segfault that is not easy
to trace.
Including time.h fixes the problem. Some games manually declared
ctime() and avoided the bug. These declarations have also been
replaced with the include.
Marking non-magic items caused segfaults because item_color was set to
NULL. item_type could also be used as an out-of-bounds index. These
problems have been fixed by only using these variables when the mark
argument is false, in which case they are properly initialized.
A fall-through case statement was also fixed.
It is possible for getpwuid() to return NULL. Such a failure will no
longer cause a segfault. However, the call to getpwuid() may normally
not be reachable.
When using the -n option, UltraRogue will look for character files in a
single location, similar to save files.
The location is chosen by defining CHRDIR in getplay.c, at least until
UltraRogue gets integrated with the build systems.
The functions for restoring saved games failed to properly correct the
t_chasee pointer of monsters chasing the player. Such monsters would
attempt to chase NULL instead, with predictable results.
A for loop had no braces around its body, which was a single if-else
statement. In Advanced Rogue 5, another statement had been added,
accidentally removing the if-else from the loop. This could have
resulted in an out-of-bounds access to the options array.
In the other games, the added braces are only for clarity.
The r_flags field in struct room was being written as an int and read
as a short. This caused the restore functions to receive the wrong
data, usually an impossible string length, and abort.
This breaks save compatibility, though the save files had problems
anyway: the r_fires field should have been used, instead of reading and
writing r_flags twice.
The new function md_random_seed() has replaced time() + getpid() and
similar methods. Putting everything in mdport.c slightly reduces the
warnings and workarounds.
Rogue V3 allowed the player to gain perpetual haste by quaffing a
potion of haste while already hasted. This is supposed to remove the
haste effect and cause temporary paralysis.
Super-Rogue removed haste correctly, but gave confusing messages.
Like an earlier bug with detecting monsters, the fuses responsible for
ending levitation and hallucination were not recognized by
rs_write_daemons(). They got left out of the savefile, so after
restoring, the effect never wore off.
I think this is the first bugfix I've ever made that reduced the game's
difficulty.
The Visual Studio project file failed to define ALLSCORES, causing the
score file to be limited to one entry per UID. Since the UID is always
set to 42 on Windows, only one entry could ever appear in the list.
Violet fungi (renamed venus flytraps in Rogue V5) do an increasing
amount of damage each time they hit. If they miss, you still suffer
the same number of HP. This worked by keeping a counter and printing
new damage strings into monsters[5].m_stats.s_dmg, which is the
"prototype" of that particular monster.
Each individual monster has its own damage string. Apparently these
were once char *, pointing to the same string as the prototype. When
the s_dmg member was changed to be an internal char array, changing the
prototype's damage string no longer had any effect on actual monsters.
As a result, flytraps did no damage on a hit, or only one point in V5.
The mechanism for doing damage on a miss continued to work.
This has been fixed by overwriting the individual monster's damage
string instead of the prototype's. It is now no longer necessary to
reset the damage string when the flytrap is killed. The method for
resetting it when the hero teleports away had to be modified. Comments
referencing the long-unused xstr have been removed.
The functions for displaying the list of identified items begin by
prompting for the category of item, using msg(). Rogue V4 left this
prompt on the screen after displaying the discovery list. Rogue V5
erased the message window even if the process of printing the list
created another message which the player had not read.
Messages are now cleared in endline(), which is capable of checking
whether clearing should be done.
This fixes all warnings produced by GCC 5, except the ones related to
system functions. Those could be fixed by including the proper headers,
but it would be better to replace the system-dependent code with
functions from mdport.c.
fuse() now expects a pointer as the argument to a fuse function. If
this is one of the functions that takes int, fuse() follows the pointer
and stores that value in the f_list slot, in the integer field of the
argument union. When the fuse goes off, do_fuses() recognizes the
function and passes it the integer field instead of the pointer.
This has the disadvantage of hard-coding the functions that require int
in daemon.c, but since the int is copied into f_list, it no longer has
to be in static or global memory, which simplifies several files.
Some calls to runto() were given a pointer to the player struct instead
of to the player's coordinates. A call to death() was passed a pointer
to a monster instead of the monster's type number.
