This contains all of the static stuff that was previously embedded in the Entity static root. This solves a bunch of problems like circular dependencies between parent and child classes, encapsulating logic and reducing the size of the enormous Entity.php.
This is a similar refactor to the one I recently did for tiles.
- Entity::createEntity() is removed. In its place are Entity::create() (runtime creation, use where you'd use a constructor, accepts a ::class parameter, throws exceptions on unknown entities) and Entity::createFromData() (internal, used to restore entities from chunks, swallows unknown entities and returns null).
- Entity::registerEntity() is renamed to Entity::register().
- Added Entity::override() to allow overriding factory classes without touching save IDs. This allows more cleanly extending & overriding entities. This method only allows overriding registered Entity classes with children of that class, which makes code using the factory much more sane and allows to provide safety guarantees which make the code less nasty.
- Entity::getKnownEntityTypes() is renamed to Entity::getKnownTypes().
- ProjectileItem::getProjectileEntityType() now returns a ::class constant instead of a stringy ID.
- Cleaned up a bunch of nasty code, particularly in Bow.
If a plugin was involved in a crash, we can't safely blame it for the crash, since it might have innocently triggered a core bug. Furthermore, it's difficult to accurately detect plugin causing things like invalid argument crashes.
it's much less expensive to just calculate the modulo of the current tick and 20, and overwrite past entries. The effect is the same. The only difference is that the arrays won't be ordered by time, but that doesn't matter anyway.
This is better for performance because these then don't need to be reevaluated every time they are called.
When encountering an unqualified function or constant reference, PHP will first try to locate a symbol in the current namespace by that name, and then fall back to the global namespace.
This short-circuits the check, which has substantial performance effects in some cases - in particular, ord(), chr() and strlen() show ~1500x faster calls when they are fully qualified.
However, this doesn't mean that PM is getting a massive amount faster. In real world terms, this translates to about 10-15% performance improvement.
But before anyone gets excited, you should know that the CodeOptimizer in the PreProcessor repo has been applying fully-qualified symbol optimizations to Jenkins builds for years, which is one of the reasons why Jenkins builds have better performance than home-built or source installations.
We're choosing to do this for the sake of future SafePHP integration and also to be able to get rid of the buggy CodeOptimizer, so that phar and source are more consistent.
