In vanilla it doesn't drop the exact number of points you collected. Rather, you lose a little for every level above 1 you had (1 level requires 7 points, later levels require +2 per level), and can recover at most 100 points. Hence, if you had 10 levels, you get back enough points to fill 5 levels and most of a 6th. 14-15 levels gets you the upper bound of about 7.5 levels.
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.
This has the triple bonus effect of a) making a lot of code easier to read, b) reducing Server::getInstance() usages, and c) removing a whole bunch of Server dependencies.
The network and block namespaces are untouched by this commit due to potential for merge conflicts. These should be dealt with separately on master.
* Implemented InventoryEventProcessor, fixes#1986
Event processors can now be registered and unregistered at will. Entity inventory/armor change events are now handled by event processors instead of the inventories themselves, which allows enabling/disabling the calling of these events at will.
This now avoids stupid things happening when initializing inventory contents, since the callers for those events are now registered _after_ the contents are initialized.
Totem usage can be detected using the MODIFIER_TOTEM constant of EntityDamageEvent.
This does not currently support using the totem in the offhand because offhand is not implemented yet.
TAG_String has a UTF-8 payload, which makes it more expensive to work with. Also, skins can contain bytes which are not valid UTF-8 characters and will therefore be treated as corrupted by external tools.
Additionally a TAG_String can only hold 32767 bytes, which might become a problem in the future.
A TAG_ByteArray can hold up to 2GB of data, and there is no character encoding restrictions on it.
This includes several other changes, including:
- SLOT data properties now accept items directly
- POS data properties now accept floored Vector3s (in future this will be block positions) or null for 0,0,0
- VECTOR3F data properties now accept Vector3s or null for 0,0,0
