Issue ID




EntityQuery.SetChangedVersionFilter() is adding filters to multiple EntityQuery objects when EnityQuery objects have the same ComponentType parameter

Package: Entity Component System (ECS)


Reproduction steps:
1. Open the attached project “EntityQueryBug“
2. Enter the Play Mode
3. Observe the Console window

Expected result: EntityQuery “Query_NoFilter” has no filter
Actual result: The filter is added to both EntityQuery objects

Reproducible with: 1.0.0-exp.8 (2022.2.21f1, 2023.1.0b18, 2023.2.0a16), 1.0.8 (2022.2.21f1, 2023.1.0b18, 2023.2.0a16)
Not reproducible with: 0.51.1-preview21 (2020.3.48f1, 2021.3.26f1)

Reproducible on: Windows 11

  1. Resolution Note:

    There are no fixes planned for this Bug

  2. Resolution Note (1.0.X):

    This behavior is expected and working as designed. Each system maintains a cache of the EntityQuery objects it creates, and queries created within a single system with the same query description will return a reference to the previously-cached EntityQuery object instead of creating a new instance. Other Entities features rely on this behavior.

    This is definitely a regular source of confusion, and we're investigating a set of design changes that would allow us to eliminate this behavior, but this change is unlikely to happen within the Entities 1.x timeframe.
