GameplayEventFilter

Remarks

This is what doc 28 means by "costs nothing when nothing dies". "Kill ten undead in Queensdale" is this struct — a verb range, a scene and a tag query — and matching it is a handful of integer comparisons against an event that was going to be posted anyway. There is no polling and no per-frame work for an objective nobody is progressing.

⚠ An empty verb range matches nothing, and that is the point. A filter is built from a name a designer wrote, and RangeOf answers an empty range for a name the content does not have. The other reading — empty means unfiltered — turns one typo in one objective into an objective that completes on the first thing that happens anywhere. Wanting every verb is EveryVerb, which is a thing a caller has to write down.
