Use an enum class to prevent implicit conversion between trigger
behavior flags and other integers. Fix up various resulting breaks,
which look like bugs:
- Descent 2 editor mode could modify trigger::flags, but used
TRIGGER_FLAG_* values, which specify the actions for a Descent 1
trigger when it executes, not the behavior properties for a trigger.
- Adding a trigger set its flags to 0, then cleared all flags except
TRIGGER_ON. Since the flags were just set to 0, the mask operation is
useless. Remove it.
- trigger_turn_all_ON cleared all flags except TRIGGER_ON. This seems
to be completely wrong. Change it to remove
trigger_behavior_flags::disabled. Descent 1 has no (working) support
for disabling triggers, so make trigger_turn_all_ON exclusive to
Descent 2.
- wall_restore_all would enable TRIGGER_ON in both games. Descent 1
never reads TRIGGER_ON. Descent 2 uses this field for trigger
behavior flags, and TRIGGER_ON is not a behavior flag.
- For Descent 1 builds, remove the modification of the field.
- For Descent 2 builds, change it to clear
trigger_behavior_flags::disabled.
Previously, valptridx used PREFIX for allow-invalid+mutable, c#PREFIX
for allow-invalid+const, v#PREFIX for require-valid+mutable, vc#PREFIX
for require-valid+const. Convert the types, factories, and all usage
sites to specify a qualifier for all four combinations:
im#PREFIX -> allow-invalid+mutable
ic#PREFIX -> allow-invalid+const
vm#PREFIX -> require-valid+mutable
vc#PREFIX -> require-valid+const
Changes to common/include/valptridx.h and common/include/fwd-valptridx.h
are manual. All other changes are generated by:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\(v\?\)\(\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/\1m\2/g'
for the 'm' prefix and:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\([cm]\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/i&/g'
for the 'i' prefix.
When responding to EVENT_WINDOW_CLOSE, set MainWindow to nullptr - fixing multiple issues with these dialogs including the inability to re-open them and a crash on exiting the editor.
This ensures the event system will know what's going on. Also remove the 'likely' branch prediction macro from close_wall_window because close_wall_window will only be called outside of the wall dialog's handler (to open a different dialog or close the editor).
Save unique_ptr's to UI_GADGET_BUTTON's in similar/editor/med.cpp and similar/editor/medwall.cpp. Fixes compile errors and resolves a crash when attempting to access both dialogs' gadgets (input event processing is the first attempt).
