GameplayTagQuery

class

Gameplay/Vixen.Gameplay/Tags/GameplayTagQuery.cs:24

csharp

public sealed class GameplayTagQuery

A rule about tags: all of these, any of these, none of these.

Read the guide page for this →

Remarks

Three lists and nothing else, deliberately. An arbitrary boolean expression over tags is a thing a generated inspector cannot draw, a thing a designer reads wrong, and a thing whose evaluation order becomes a question. All of · any of · none of covers every rule doc 28 asks for — an ability's target filter, an effect's immunity list, a vendor's stock condition, a quest objective's kill filter, a chat channel's gate — and it composes, because a rule needing more than one of these is more than one rule.

Resolved once, against a table. The authored form is dotted strings; what is kept is GameplayTagRanges, so matching never touches the table or a string. A prefix the content does not have resolves to an empty range, which matches nothing — so an any list of unknown tags fails and a none list of unknown tags passes, both of which are the safe reading.

public ReadOnlySpan<GameplayTagRange> Any
The prefixes a set must match at least one of.
public ReadOnlySpan<GameplayTagRange> None
