Struct EntityQueryMask

Provides an efficient test of whether a specific archetype is included in the set of archetypes matched by an EntityQuery.

Namespace: Unity.Entities
Syntax
public struct EntityQueryMask
Remarks

Use a query mask to quickly identify whether an entity's archetype would be matched by an EntityQuery.

           var mask = query.GetEntityQueryMask();
           bool doesArchetypeMatch = mask.MatchesIgnoreFilter(entity);

You can create up to 1024 unique EntityQueryMasks in an application. Note that EntityQueryMask only filters by Archetype. It doesn't support EntityQuery shared component, change filtering, or enableable components.
