Event

One .dat file per scheduled event. Each file defines its own schedule, rewards, monster spawns, and stage progression. High-level enable flags live in GameServerInfo - Event.dat; this folder holds the detailed content each event needs to run.

File Location#

Data/Event/

Every file loaded once at GameServer startup. Changes require a restart.

File Format#

All event files use the same section-based text format:

<section_id>
//<column comments>
<row data>
<row data>
end

<next_section_id>
//<column comments>
<row data>
end
  • Sections are numbered starting from 0 (or sometimes comment-labeled)
  • Each section begins with its ID on its own line
  • Column header lines start with //
  • Data rows follow, whitespace-delimited (tabs or spaces both fine)
  • Each section ends with end on its own line

A wildcard * in a time column means "any". For example, * * * * 0 0 0 means every year, month, day, and weekday, at 00:00:00.

Common Sections Across Events#

  • Time block - sections using the 7-column year/month/day/DoW/hour/minute/second format for scheduling
  • WarningTime / NotifyTime / EventTime / CloseTime - how long the pre-event warning, entry window, main run, and cleanup last (minutes)
  • Level / Reward tables - per-tier experience, zen, item rewards indexed by event level
  • Monster spawn blocks - per-stage monster class, count, and coordinates

Individual event pages below document each file's full section layout.
