Unreleased

0.2.2 - 2024-07-07

Added

  • Added query:replace(function(...T) return ...U end) for replacing components in place
    • Method is fast pathed to replace the data to the components for each corresponding entity

Changed

  • Iterator now goes backwards instead to prevent common cases of iterator invalidation

0.2.1 - 2024-07-06

Added

  • Added jecs.Component built-in component which will be added to ids created with world:component().
    • Used to find every component id with `query(jecs.Component)

0.2.0 - 2024-07-03

Added

  • Added world:parent(entity) and jecs.ChildOf respectively as first class citizen for building parent-child relationships.
    • Give a parent to an entity with world:add($source, pair(ChildOf, $target))
    • Use world:parent(entity) to find the target of the relationship
  • Added user-facing Luau types

Changed

  • Improved iteration speeds 20-40% by manually indexing rather than using next() 😱

0.1.1 - 2024-05-19

Added

  • Added world:clear(entity) for removing the components to the corresponding entity
  • Added Typescript Types

0.1.0 - 2024-05-13

Changed

  • Optimized iterator

0.1.0-rc.6 - 2024-05-13

Added

  • Added a jecs.Wildcard term
    • it lets you query any partially matched pairs

0.1.0-rc.5 - 2024-05-10

Added

  • Added Entity relationships for creating logical connections between entities
  • Added world:__iter method which allows for iteration over the whole world to get every entity
    • used for reconciling whole worlds such as via replication, saving/loading, etc
  • Added world:add(entity, component) which adds a component to the entity
    • it is an idempotent function, so calling it twice and in any order should be fine

Fixed

  • Fixed component overriding when in disorder
    • Previously setting the components in different order results in it overriding component data because it incorrectly mapped the index of the column. So it took the index from the source archetype rather than the destination archetype

[0.0.0-prototype.rc.3] - 2024-05-01

Added

  • Added observers
  • Added an arm to query query:without() for chaining invariants.

Changed

  • Separates ranges for components and entity IDs.

    • IDs created with world:component() will promote array lookups rather than map lookups in the componentIndex which is a significant boost

  • No longer caches the column pointers directly and instead the column indices which stay persistent even when data is reallocated during swap-removals

    • This was an issue with the iterator being invalidated when you move an entity to a different archetype.

Fixedhttps://github.com/Ukendio/jecs/releases/tag/v0.0.0-prototype.rc.3

  • Fixed a bug where changing an existing component would be slow because it was always appending changing the row of the entity record
    • The fix dramatically improves times where it is basically down to just the speed of setting a field in a table

0.0.0-prototype.rc.2 - 2024-04-26

Changed

  • Optimized the creation of the query

    • It will now finds the smallest archetype map to iterate over

  • Optimized the query iterator

    • It will now populates iterator with columns for faster indexing

  • Renamed the insertion method from world:add to world:set to better reflect what it does.

0.0.0-prototype.rc.2 - 2024-04-23

  • Initial release
