v2020.12.14

Added

• Added a warning when setnpcdisplay() or setunitdata() is called on a floating NPC. (#2907)
• Added support for RSW formats up to 2.5 for reading map water level. (#2916)
• Added a status->check_skilluse_mapzone() function, simplifying status->check_skilluse() and adding a useful plugin hooking point. (#2893)

Changed

• Second part of the refactoring of the functions in unit.c, adding code documentation and following the code style guidelines. Functions have been renamed when backward compatible changes to the arguments or return values were made. (#2783)
  • Added proper documentation in doxygen-format.
  • Moved variables declaration closer to their first use
  • Corrected mistreatment on checks of non-boolean variables
  • Renamed some variables to clarify their use
  • Saved re-used calculations in variables or create local macros for them
  • Simplified logical checks / conditions when possible
  • Changed returning error-code in functions to obey code-style guidelines (Functions that are affected by this are renamed so that custom code fails to compile as to point at that change of behavior.)
  • Split too long lines according to code-style guidelines
  • Made functions use enums for directions (enum unit_dir), when dealing with a direction context
  • Reduced code-repetition by separating code-chunks into new functions
  • Fixed remaining code-style after applying all these changes if necessary
  • The following functions have been refactored:
    • unit->walktobl() (renamed to unit->walk_tobl())
    • unit->run_hit()
    • unit->run()
    • unit->escape() (renamed to unit->attempt_escape())
    • unit->movepos()
    • unit->walk_toxy_timer() (return value fix)
    • unit->blown() (renamed to unit->push())
    • path->blownpos() (related to the unit->blown() change)
    • added npc->handle_touch_events() function
    • the is_boss() macro now returns a boolean
• Added static assertion checks to prevent MAX_STORAGE and MAX_GUILD_STORAGE from causing oversized inter-server packets (#2904)
• Disabled the HP bar on Emperium and MVP monsters by default. The configuration flag show_monster_hp_bar has been extended to a bitmask, to allow specifying different setting for normal monsters, Emperium and MVPs. The new default value is 1 (normal monsters only), while the value corresponding to the previous behavior is 7 (4|2|1). (#2821)

Fixed

• Fixed a walk delay error in unit_stop_walking(). (part of #2783)
• Fixed homunculi and mercenaries not warping back to their master in time. (part of #2783)
• Reverted an unintended logical change in unit->walk_toxy_timer() done during the first part of the unit.c refactoring. (#2783)
• Fixed a warning (Warning: #1681 Integer display width is deprecated and will be removed in a future release.) when importing the database schema in recent versions of MySQL. (#2903)
• Fixed compilation with recent versions of the MySQL/MariaDB client libraries. (#2917)
• Fixed a farming exploit at the Cursed Spirit NPC. (#2883)
• Fixed the configuration flag monster_loot_type not working as intended. (#2855, issue #2834)

Removed

• Removed the unused function skill->get_linked_song_dance_id(). (#2906)
