On Windows last_position_x/y (from SDL_GetWindowPosition()) was 0, 0 when
coming from fullscreen, and creating a window at position (0, 0) cuts off
the window decorations (SDL-Bug?) so the window can't even be moved
around anymore.
So now we only use the last_position_* if last_position_y was > 24, so we
have enough of the title bar to move the window around with the mouse.
This is part of #484
The docs "forget" to mention that. So it's not enough to check for
SDL_WINDOW_FULLSCREEN alone, we would trigger the code intented for the
real fullscreen if we're switching to / running in fullscreen desktop
mode. Add and addition check that SDL_WINDOW_FULLSCREEN_DESKTOP isn't
set.
This may fix issue #484.
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.
This is part of #473.
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.
