With this quicksaves can be loaded from the menu. They cannot be saved.
That's an artificial limitation to match the behavior of autosaves. I
think both should behave the same because their comment string are
formatted the same...
This is somewhat hacky. Until now the menu assumed that all savegames
are named from save0 to saveX, where save0 is the autosave slot. There
were 16 slots per page * 2 pages = 32 savegame slot, so the highest slot
was save31. I've reduced the slot per page to 14 to make room for one
quicksave slot and one empty line between it and the first regular slot.
That alone would reduce the number of slots to 28, making the four
highest slots unreachable. So I've increased the number of pages to 4,
there're now 14 slots per page * 4 pages = 56 slots.
The quicksave slot is shown on every page, because it was the easiest
way to integrate it into the existing code. Everything else would
require the paging logic to be rewritten in a way that different pages
can have a different number of slots and a different layout.

Demos are special. To the client they're more or less the same as normal
maps, the only difference is that the client never joines the server. So
we're never getting the first valid frame txpaht indicates the end of
the connection process. We're using that one to drop out of pause
mode... As a result the client stays in pause mode forever and "hangs".
Work around this by entering pause mode only if the local server is in
state ss_game. Demos are ss_demo. There're some more states for
cinematics, pictures, etc. Since the player can't save in those states
it should be save not check them.

Save current player position and compare with a position in the previous
frame, if position is same refresh only changed rectangle in zbuffer.
zBuffer can be damaged by models, particles and static transparent spans.
zBuffer damage is not useful for the screen refresh minimize for now,
as result of explosion can change texture light value.
Especially after savegame load not all slots in the edicts array may be
used. Check if the current entity has a classname string. This is
another part of #430.
It's unclear were this comes from, maybe it's a bug in the collision
detection. Because the collision detection is ununderstandable for
people without 'special brain type game programming' like me and even
bugfixes to it have a very high chance to break things, work around
it. Save current position, perform move, check if we're in the world
model. If we are revert to old position.
Debugged and work arounf suggested by @BjossiAlfreds. Fixes#443.
This is another code inconsistency, we must not clamp the current health
to the client max health (which apparently is always 100) but to the
current max health of the player entity.
Analyzed and fix suggest by @BjossiAlfreds, fixes#441.
This is another corner case. Parasites have a bbox height of 24,
walkmonster_start_go() hardcodes a viewheight of 25. Therefor most
traces in other functions like visible() overshoot the parasite.
Fix this by not overriding the monster viewheight.
Analyzed and fix suggested by @BjossiAlfreds. Closes issue #440.
This rather sophisticated command prints all entities of one or more
given classes and their coordinates. Possible classes are:
* ammo
* items
* keys
* monsters
* weapons
Classes can be combined into one command, e.g. `listentities ammo keys'
would print all ammunition and all keys. The special class `all` prints
all entities, regardless of their class.
The command is protected by `cheats 1`.
This is part of issue #430.
A command that teleports the player to abitrary locations was often
requested and may be helpfull for debugging, so finally add it. It works
like a normal teleporter: It moves the player to the requested location,
clears all movements, tells the server and clients that the entity just
teleported and telefrags everything that's in the target location.
The implementation does not verify if the requested location is save,
the player may teleport into the world model or even the void. But the
requested Z coordinate is elevated by 10 units to prevent the player
getting stuck in the floor.
The command is protected by sv_cheats.
This is part of issue #430.
The fallback logic is: r1q2 style URLs -> q2pro style URLs -> UDP. In
case that an r1q2 or q2pro server is missing files, we may fall through
to UDP and download files over abysmal slow UDP that are available over
HTTP. To work around this problem we reset the precacher iterations back
to 0 and start over with r1q2 style URLs. This works as long as we're
able to download all files. But if one or more files are unavailable
over all three download options we'll run into an endless loop. Mitigate
this by starting over only once. This comes with the drawback that on
servers that miss more than one file downloads might done over UDP were
HTTP is available. In that case the server should be fixed.
This closes#429.
This prevenits the worlds from advancing during client connect. The
player won't get attacked by monsters or hurt by the environment. Note
that in baseq2 there're still 4 world frames processed by the game and
100 world frames if the player enters a level that he or she already
visited. Both aren't a big problem, 4 world frames are hardly enough
for monsters starting to attack and in most levels the starting area
can't be reached by monsters and is free from environmental effects.
Pause mode is only entered for local servers and only in single player
mode. This should prevent problems with coop and deathmatch games.
The behaviour can be controlled by `cl_loadpaused`:
* `0`: Do not enter pause mode, Vanilla Quake I behaviour.
* `1`: Enter pause mode at load and leave it at first regular server
frame.
* `2`: Enter pause mode at load, never leave it. The player must leave
it by hand.
This was requested in issue #417.
cvar operations are special commands that allow the programmatic
manipulation of cvar values. 'reset' resets a given cvar to it's
default value, e.g. `reset r_mode' would reset `r_mode` to `4`.
'resetall' resets all known cvar with the exception of `game`.
The code is based upon q2pro.
This is part of issue #414.
44472722e added some sanity checks to the AI code. The checks in
ai_run() are likely wrong because the enemy entity might be already
NULL if we arrive their. By aborting early the code is unable to
determine a new enemy or return the monster to idle state, so the
monster will wait forever for an enemy that'll never come.
This happens only in monster vs. monster fights. Never in monster vs.
player, that game ends if the player dies.
In theory this change should be harmless, because if the enemy entity is
gone it won't generate sound targets now be visible. If the game crashes
by self->enemy being NULL we've got a problem elsewere.
This was reported by @BjossiAlfreds in #483. He also suggested the fix.
When searching for the player FinTarget() always goes after sound
targets and aborts as soon as it finds one. So if the player is
constantly generating sounds - for example firing the machine gun -
there's a high chance that monsters will only hear but never see
him. Work around this by adding a small timeout to player noises, make
sure that at least 3 frames passed since the last noise. This gives
monsters 2 frames to see the player.
This bug was present in the original code, this is a small gameplay
change.
The problem was analysed by @BjossiAlfreds in #436. He also suggested
the fix.
M_MoveFrame() calls first the AI functions that decide if a monster
should attack or not. After that the monsters think function is called
which walks through berserk_frames_stand[]. Even if the AI function found
an enemy and decided to attack, the monster is still standing for this
frame and berserker_fidget() is called. It may override the earlier
earlier decision, aborting the attack. Even worse this may let the
berserker stuck, because AI_STAND_GROUND may be cleared which prevents
further attacks.
This bug was present in the original code, so this is small gameplay
change. It's likely also present in both addons.
Reported and analyzed by @BjossiAlfreds in issue #433. He also suggested
the fix.
Like most other cvars 'sensitivity' allowes for float values. But until
now mouse events were handled as integers which led to some confusing
problems. This was especially noticeable at values lower than 1, small
mouse movements were cut to 0 and discarded. Since the clients movement
code is written in floats and we're already using floats for joystick
movement switch the mouse event handling over to them, too.
This should have any impact on configs were 'sensitivity' is ste to
integral values. If it was set to decimal values the behaviour is now
correct.
This fixes#419.
Check if we're in the requested mode after the fullscreen window was
created. If not: Try to switch again in the requested mode by calling
SDL_SetWindowDisplayMode(). If that's successfull set the new window
size with SDL_SetWindowSize(). That shouldn't be necessary, at least to
SDLs crappy doku, but without the subsequent SDL_GetWindowDisplayMode()
call fails with 'Invalid Window'. Use that call to check if we're now
in the requested mode. If yes, process. If not abort and trigger the
fallback magic. It'll set `r_mode 4` and `vid_fullscreen 0`.
Caveat: In the worst case this will switch the display mode 3 times.
To create the window, to work around the bug and to set a refresh rate.
No problem for flat panels, but my unforgotten Trinitron CRT would
have cried in pain.
* Normaly SDL chooses a sane refresh rate for fullscreen windows. Users
may want to override that, so provide a new cvar `vid_rate`. If it's
set to a value greater than 0, we're trying to get a mode close to the
requested resolution and refresh rate and switch to that.
* A bug in SDL may leave us in the wrong mode, detect that condition and
abort. See https://bugzilla.libsdl.org/show_bug.cgi?id=4700 for details.
This is part of issue #302.
Print a list of all available modes as soon as SDLs video backend
initializes and the real display mode after the window was created
or altered.
This hopefully helps debbuging problem with display mode selection, see
issue #302 for an example.
-Add back use of last_position_x and last_position_y
-last_position_x and last_position_y will be set to undefined when the window is shutdown IF the current display used is not the desired display
-last_display will be set to desired display at window shutdown if not the same
-vid_displayindex clamped using ClampDisplayIndexCvar() at startup and window shutdown
-We only need to init the display indices once in GLimp_Init
-We only need to clear the display indices once in GLimp_Shutdown
-Remove extra 'displayindex' variable
-SDL_GetNumVideoDisplays() will always remain the same after the call to SDL_Init(SDL_INIT_VIDEO), so it makes sense to set in GLimp_Init where we do this.
Otherwise the entities origin might be in the surface, which causes it
to be rendered in full black. This fix is a port from KMQuake2, reported
by @m-x-d. Closes#407.
There's an "enable alt joy keys" command now. If a key is bound to that
command, all joystick buttons (incl. hat and triggers) are turned from
K_JOYx into K_JOYx_ALT, which allows two keybindings on the same key,
one with the altselector pressed and one without.
If there's no keybinding for K_JOYx_ALT, it will use the binding for
just K_JOYx as a fallback (if it exists).
This is especially handy to create direct bindings for all the weapons
on the (limited amount of) Joystick buttons.
