While in baseq2 monsters had the abillity to duck it wasn't used
often. The same goes for medics, there are only a few throughout the
whole single player campaign. In rogue things are differed. Due to
some AI changes like support for dodging monsters duck more often and
there a a lot of medics and even it's improved version, the medic
commander.
When a monster dies it's mmove_t is set to the death animation and
it's AI flags are left as they are. When a monster is resurrected by
a medic, the AI flags are reset to 0 and it's spawn function is
called again. Normally this is totally save. But when there're two
medics and both try to resurrect there monster there's a small window
for the monster being respawned without the AI flags reset.
In this case the mmove_t is set to the monsters standard animation,
while the AI flags may be still contain AI_DUCK. When AI_DUCK is set,
but the current animation is not one of the duck animations, the
monster may get stuck. There's even a comment in the code for that
case. ;) Solve this problem by resetting AI_DUCK as soon as the
monster dies.
With this change applied I was unable to reproduce any problem in
regard to medics, medic commanders, resurrection and spwaning of new
monsters.
This closes issue #6.
When the monster was already killed by another monster or a coop player
some references may be NULL and the game was crashed. This was observed
by maraakte, who reported it in issue #164. I've just merged his fix
from q2dos.
teleport_time has nothing to do with teleports, it's just the time
since the last player sound. Rename it accordingly. This was suggest
by maraakate in yquake2 issue #162.
In ai_checkattack() is a check against AI_SOUND_TARGET. If the player
made a noice and the the monster noticed this noise it's true. If
that noice was more than 5 seconds ago the monster forgets that event
and continues with it's search for the player. Otherwise it informs
the surrounding monsters that something interesting has happened and
then returns false. So the problem is: Even if the monster heard the
player and can see him, it aborts at this point.
Fix this by adding an additional visibility check. Do the sound
checking only if the player is not visible, otherwise just continue.
This was reported by shoober420 and debbuged by maraakate. This fix
was DanielGibons idea. This commit fixes yquake2 issue #162.
On most implementations atof() is just a wrapper around strtod().
Calling strtof() saves one cast. For the sake of cinsistency change
atoi() to (int)strtol(), it's a noop. Reported by maraakate in yquake2
issue #160.
I don't think that this has a visible effect, because there shouldn't be
any unknown entities in maps creates with the official entities.def.
This was reported by maraakate in quake2 issue #160.
I don't think that this has any visible effect, but it's saver than
assume that in multiplayer all clients enter the intermission at the
same time. This was reported by maraakate in yquake2 issue #160.
To fix some bug, in baseq2 and xatrix
if(coop->value)
{
if(FindTargeget(self))
{
return;
}
}
was moved from ai_run() to ai_checkattack().
Do the same here, but without the bug from yquake2/#151
The old whitelist was a leftover from the early days of YQ2. It should
run on most / all architectures, as long SDL supports them. As suggested
by smcv in issue #138 generate the OSTYPE and ARCH defines by the build
system instead of hardcoding it.
Savegame compatibility is provided by bumping the savegame version. Old
savegames are compared against the old OSTYPE and ARCH defined, new ones
against the new defines. This compatibility code should be removed
somewhere in the distant future.
Without this change the conditionals at g_misc.c:199 and 381 wouldn't
trigger until level.framenum reach it's previous value, resulting in
much to few debris or gibs being thrown. This fixes#104.
Many thanks to maraakate for the analysis and the idea how to fix it.

In ClientThink(), the float value ent->velocity[i]*8 is saved into
a short and if the value is too big for a short, in 32bit gcc builds
the short is set to SHRT_MIN, resulting in the player being pressed
down instead of up.
Now we put the result in a 32bit int first (which should be big enough)
and assign the int to the short. This still overflows, but with -fwrapv
at least in a defined way (most probably the same way the original
binaries did).
The Makefile now sets $CC to gcc for MingW builds, this should fix
https://github.com/yquake2/xatrix/issues/3
And while I was at it, when the game lib is loaded, it prints the date
it was built, this is especially interesting for our Win32 binaries.
In RHANGAR1 the turret didn't blow up the ceiling when friendly fire
was off, because in ClientTeam() both entities were set to "" (no team),
but OnSameTeam() just did a strcmp() instead of checking this special
case (no team).
We check this now and thus it works. Hooray.
The savegame table entry for this function was invalid, but it doesn't
need to be saved anyway, so I just deleted it from the table.
COM_FileExtension() was parsing strings from beginning to end, bailing
out as soon as '.' was found and treating everything thereafter as the
file extension. That behavior caused problem with relatives pathes
like models/monsters/tank/../ctank/skin.pcx. The new implementation uses
strrchr() to determine the last '.'.
