Players are not robots, but the show-path cheat tried to pretend they
are, and triggered a BUG warning[1] when looking up robot information
from the player object. Fix this by passing in the robot_info when the
caller is providing a robot, and a named `nullptr` value (as
`create_path_unused_robot_info`) when the caller is providing a
non-robot object.
[1] As below, but repeated many times

Zero the entire array, then overwrite the leading portion with the
received data. This permits the compiler to do a fixed number of large
stores, instead of a variable number of small stores.
The type aliases are sufficient. Individual bytebuffer_t
implementations can define a `static constexpr` member `endian` from the
type alias and rely on `std::integral_constant<T, V>::operator()`
instead of defining a `static` method just to return an instance of the
`std::integral_constant`.
`check_header_includes` requires `git` to be installed and able to list
files from a working copy. When `GIT=''` is used, SConstruct is told
not to find or run `git`. This caused a traceback when
`check_header_includes` tried to use git to list headers. Reorder the
test to report a clear failure message.
Zero the entire array, rather than adjusting the loop to account for the
count of segments in the level. The array may not need to be zeroed at
all, but this is cheap and guarantees consistent results.
attempt_to_steal_item_3 always fails if the thief is not in
AIM_THIEF_ATTACK mode. The caller will call attempt_to_steal_item_3
repeatedly in some cases, but the mode does not change during the calls,
so if one fails for this reason, then all will fail for this reason.
Lift the check into the caller so that the loop of repeated calls can be
skipped if the mode check fails.
Use `object &` instead of `vmobjptr_t`. This should generate equivalent
code, but produce smaller debug information and may require less
inlining by the compiler.
Every caller passes `1`, so remove the parameter and always use `1`.
For backward compatibility with the previous network protocol, continue
to send a `1` in the network message.
- Write a more specific message on failure
- Defer writing a success message until `spit_powerup` succeeds
- Defer the sound too
- Rewrite the success message to tell how much ammo remains
Commit 8c8b7419b6 defined Shift-F5 and Shift-F6 to adjust the VR
handling. However, Shift-F5 and Shift-F6 already had a meaning: drop
primary weapon / drop secondary weapon. The ordering of the logic
causes the new VR handling to suppress the old drop handling, thus
preventing players from dropping weapons. Disable the VR meaning for
these keys so that drop-weapon works again, since F1 documents those
keys as drop-weapon.
Fixes: 8c8b7419b6 ("Improved conditionals for stereo vs non-stereo modes.")
This allows taking the input by-value instead of by-reference, while
still protecting against unwanted type conversion.
Add some basic static_assert tests that the swapped values are correct.
Commit f1606f7747 ("Simplify test for
__builtin_bswap16") changed the SConstruct test to either define both
DXX_HAVE_BUILTIN_BSWAP and DXX_HAVE_BUILTIN_BSWAP16 or to define neither
of them. Follow up that commit by removing the definition of
DXX_HAVE_BUILTIN_BSWAP16 and redirecting uses of it to
DXX_HAVE_BUILTIN_BSWAP.
The conditional definition of a D2X flag causes a technical ODR
violation. It is legal, though not useful, to define this flag in D1X
and in common code. Remove the preprocessor guard so that D2X and
common code use the same definition for the enum.
Split check_index_range to check_index_range+check_index_range_size.
Redirect check_explicit_index_range_ref to check_index_range_size, so
that the index_type is not truncated and then extended.
Use a single constructor that accepts anything convertible to both of
the required types, rather than special constructors for:
- Accepting a qualified_segment
- Accepting a variant of susegment with compatible const qualifiers
- Accepting a type T that converts to qualified_segment
This reduces the number of constructors to consider, which improves
error messages when an invalid input is used.
v29_trigger and v30_trigger define a field `time`. v29_trigger never
initializes it. v30_trigger initializes it from the uninitialized
v29_trigger in legacy mode, and from a file field otherwise. No program
logic ever reads this member, so remove it.
Commit 7f2df64649 converted `mission_menu` to inherit from `listbox`,
but introduced an off-by-one bug in the handling of subdirectories.
`listbox` must be told how many strings it is given. Subdirectories
have one extra string, to represent the `listbox_go_up` element. The
count passed to `listbox` incorrectly failed to adjust for the generated
go-up element, causing listbox not to show the last string in the list.
Change the logic to adjust the count to include the extra element.

When a file name is available, use SDL_RWFromFile + Mix_LoadMUSType_RW,
rather than calling Mix_LoadMUS(filename). This allows the calling code
to be more consistent.
SDL1 defines Mix_LoadMUS_RW as:
```
Mix_LoadMUS_RW(SDL_RWops *rw)
Mix_LoadMUSType_RW(rw, MUS_NONE, SDL_FALSE);
```
SDL2 defines Mix_LoadMUS_RW as:
```
Mix_LoadMUS_RW(SDL_RWops *src, int freesrc)
Mix_LoadMUSType_RW(src, MUS_NONE, freesrc);
```
The version with freesrc is preferable, and Rebirth used it to set
freesrc=SDL_TRUE in SDL2 mode. For SDL1, Rebirth used special logic
in the reset() call to emulate setting freesrc=SDL_TRUE. SDL1 also
exposes Mix_LoadMUSType_RW, which allows the caller to set freesrc in
both SDL1 and SDL2. Switch to that, so that the same code is used in
SDL1 and SDL2.
If the file is accessible via PhysFS, the next branch, based on
PHYSFS_openRead, will find it and use it. If it is not accessible via
PhysFS, then attempting to resolve its path would fail. Thus, this
attempt is redundant regardless of whether the file is reachable by
PhysFS. Remove it.
The contents of the output buffer are undefined if PHYSFSX_getRealPath
fails, so mark the function as [[nodiscard]] and modify all callers to
check that the function succeeded.
Rework the error paths to return path-specific status codes so that the
caller can report exactly which step caused an HMP file to be rejected.
On error, print this reason numerically and, if the reason was a PhysFS
error, also print the PhysFS error code numerically and symbolically.
If the type is not None, an earlier statement will have already
returned. Thus, the type can be assumed to be None if these test
statements are reached.
Previously, if the filename had no dots, then mix_play_file would refuse
to play it at all. This was excessive, as only the check for hmp needs
a filename with a dot in it. Change the logic so that a dot-less file
still is assumed not to be an hmp, but instead of returning, will fall
through and try the other load types.
Return the type for compatibility, but set the music type immediately.
Change callers to return without using a switch to set the music type
based on the returned value. This allows the callers to exit early on a
successful load.
Remove the `switch` in the caller, since now every path that can set
`current_music_type` will either (a) set it to None because the load
failed or (b) set it to non-None and return before reaching the
`switch`.
Return the type for compatibility, but set the music type immediately.
Change callers to return without using a switch to set the music type
based on the returned value. This allows the callers to exit early on a
successful load.
- Centralize the default value for the hook function.
- Move some static functions to the anonymous namespace.
- Define functions for setting the mixer parameters to ADLMIDI mode and
SDL_mixer mode, so that these modes can be set from more places.
