v0.9.1

[richardbiely]

This version brings lots of important bug fixes, and some new and important features.

Among the most prominent ones are:

• support for sorting for queries
• SafeEntity and WeakEntity added to aid with managing entity lifespan
• component hooks

Breaking changes:
From now on, the old and undocumented SystemBase and SystemBaseManager were removed and all examples were transitionedto the new entity-based systems.

Release Notes:

Fixed:

• unused variables error possible when compiling without asserts
• broken sringbuffer copy-constructor
• [[assume]] availability checking
• Linux efficiency cores detection (for the Intel CPUs)
• incorrectly set-up the number of performance & efficiency workers
• EntityBuilder usages that would result in no archetype change
• mismatch in Entity and EntityContainer bit layout
• double-use of "unlikely" in GAIA_ASSERT because a compiler's assert already does the same
• invalid memory accesses possible when creating queries
• incorrectly cleared query data (group info not reset)
• set_max_lifespan not working correctly
• targets_if wouldn't take the functor's return value into account
• NO operators matching on queries wouldn't work correctly in some cases

Added:

• stringbuffer iterator
• systems expose a JobHandle now
• SystemBuilder "add" function that accepts a QueryInput
• component "add", "del" and "set" hooks (can be disabled via GAIA_ENABLE_HOOKS 0)
• each world now sports its own CommandBuffer (also accessible via the query iterator)
• "modify" function added to "sset"/"sview", it can be used to trigger component updates
• archetypes accessible in iterators
• SafeEntity and WeakEntity added to aid with managing entity lifespan
• "copy_n" now accepts "ecs::CopyIter&"
• more CommandBuffer commands
• system query API brought up-to-date with query API
• sorting entities on per-query basis
• DependsOn relationship to help sort entities
• GAIA_USE_VARIADIC_API preprocessor macro to control whether or not variadic template arguments for various API is enabled (enabled by default, will be disabled by default in the future versions)

Changed:

• components almost as large as a chunk will no longer be allowed
• the default number or high/low priority workers set to match the number of perf/efficiency cores in the system
• std::invoke replaced with custom invoke

Tweaked:

• improved and faster world version handling

Removed:

• undocumented BaseSystem and BaseSystemManager removed
