Jecs v0.5.2

Highlights

• Optimized deletion/removal of children from a parent by 20%
• Reverted back to using the old type solver, will wait until user defined type functions are more stable and have support for generic packs

Changelog

• [world]:
  • Fixed world:each not iterating every archetype
• [query]:
  • Fixed the :with filter on cached queries not working properly
• [luau]:
  • Reverted the types to Pair to always return the type for the first element
    • The behaviour of supporting components in either position remains but types does not reflect this at the moment

Jecs v0.5.1

Bump patch

Jecs v0.5.0

Highlights

• Now supports cached queries which can save 3-5 microseconds by not having to recreate the same queries every frame.
• Thanks to Luau's progress to supporting user defined type functions, we can now fully type Pair, and as such I have extended support for them to support relation data if either IDs is a Component

Changelog

• [world]:
  • Fixed world:target not giving adjacent pairs
  • Added world:each to find entities with a specific Tag
  • Added world:children to find children of entity
• [query]:
  • Added query:cached
    • Adds query cache that updates itself when an archetype matching the query gets created or deleted.
• [luau]:
  • Changed how entities' types are inferred with user-defined type functions
  • Changed Pair<First, Second> to return Second if First is a Tag; otherwise, returns First.

Full Changelog: v0.4.0...v0.5.0

Jecs v0.4.0

Highlights

• Jecs now has entity recycling which will allow you to reuse 2^24 indexes 2^16 times each by giving them generations, giving you a possible range of 2^40 entities in total, you will never run out! Huge thanks to @centau and @SanderMertens for the guidance on the implementation of this!
• The query iterator has been simplified to keep the API more lightweight and transparent.
• Now that jecs is much more stable than before, I am going to take a pivot towards working on flamecs, a jecs wrapper for Flamework. Takes advantage of Flamework macros and type ID system for increased ergonomics.

Changelog

• [world]:
  • Added recycling to world:entity
    • If you see much larger entity ids, that is because its generation has been incremented
• [query]:
  • Removed query:drain
    • The default behaviour is simply to drain the iterator
  • Removed query:next
    • Just call the iterator function returned by query:iter directly if you want to get the next results
  • Removed query:replace
• [luau]:
  • Fixed query:archetypes not taking self
  • Changed so that the jecs.Pair type now returns the first element's type so you won't need to typecast anymore.

Changelog

• [world]:

  • Added debug mode, enable via setting _G.JECS_DEBUG to true
    • Make sure to set this before calling jecs or else it will not work
