A braced initialiser does not allow a narrowing conversion unless the value
is a constant expression the compiler can prove fits. Every site here holds a
runtime value: WORLD_COLS is the global guiWorldCols, the laptop screen
coordinates are built from iScreenWidthOffset, the sector limits come from the
externalised options. MSVC accepts all of it silently; clang rejects it, and
it is ill-formed.
Nothing about the generated code changes. MSVC was already performing these
conversions; the casts only say so out loud, at the 73 places where it was
happening implicitly.
The invariant: each site is wrapped in a static_cast to the element type the
initialiser already had, and nothing else is touched. No type is widened, no
expression is reassociated, no value is clamped or checked. static_cast rather
than a C-style cast so that a later reader can grep for the narrowings, and so
that none of these can quietly become a reinterpret_cast if a type changes.
Verification:
# every changed line differs only by inserted casts and their parentheses
git show HEAD -U0 | grep '^[+-][^+-]' |
sed -E 's/static_cast<[A-Za-z0-9_]+>//g; s/[()]//g; s/^[+-]//' |
sort | uniq -c | awk '$1 % 2' # no output
git show HEAD -U0 | grep -c '^+[^+]' # 38 lines, 73 casts
ninja -C build parse # narrowing class gone: 129 -> 91 sites
ninja -C build -k 0 # Release, four applications, green
ninja -C build-debug -k 0 # Debug, four applications, green

* Load old ObjectData correctly
ITS changed ObjectDataStructs::OBJECT_BOMBS_AND_OTHER::ubBombOwner data size from 1 byte to 2 bytes, and it was not taken into account when loading ObjectData
This one is big, but unless I missed something, should be all be
trivial.
scripted-diff with the following, then manually tweaked whatever needed:
```
if [ $# -ne 3 ]; then
echo "Usage: $0 '<pattern>' '<replacement>' '<filename>'"
exit 1
fi
pattern="$1"
replacement="$2"
filename="$3"
if [ ! -f "$filename" ]; then
echo "Error: File $filename does not exist."
exit 1
fi
sed -i '/'"$pattern"'/ {
:loop
$ !{
N
/'"$pattern"'.*\n.*#endif/ {
s/'"$pattern"'/'"$replacement"'/
s/#else/} else {/
s/#endif/}/
P
D
}
/'"$pattern"'/ b loop
}
}' "$filename"
echo "Replacement complete in $filename"
```
h/t to Grok2 for the sed command
Removed from function call parameters at the same time.
It was supplied to SlideTo, SlideToLocation and SoldierLocationRelativeToScreen but was never used.
* Move main executable files to their own directory
* Adapt the build to the new file structure
... and fix some weird #include's that were relying on the project root
being an include directory.
