Rewrites the Vanilla luck application formula so that luck can be
applied to items that do not have any quality defined.
See: https://luckformula.emc.gs for data and details
-----------
The rough summary is:
My goal was that in a pool, when luck was applied, the pool
rebalances so the percentages for bigger items is
lowered and smaller items is boosted.
Do this by boosting and then reducing the weight value,
so that larger numbers are penalized more than smaller numbers.
resulting in a larger reduction of entries for more common
items than the reduction on small weights,
giving smaller weights more of a chance
-----------
This work kind of obsoletes quality, but quality would be useful
for 2 items with same weight that you want luck to impact
in varying directions.
Fishing still falls into that as the weights are closer, so luck
will invalidate junk more.
This change will result in some major changes to fishing formulas.
-----------
I would love to see this change in Vanilla, so Mojang please pull :)
hashCodes are not allowed to change, however bukkit used a value
that does change, the entityId.
When an entity is teleported dimensions, the entity reference is
replaced with a new one with a new entity ID.
For hashCode, we can simply use the UUID's hashCode to keep
the hashCode from changing.
equals() is ok to use getEntityId() because equals() should only
be true if both the left and right are the same reference.
Since entity ids can not duplicate during runtime, this
check is essentially the same as this.getHandle() == other.getHandle()
However, replaced it too to make it clearer of intent.
To teleport an entity between dimensions, the server makes a copy
and puts the copy in the new location, and marks the old one dead.
If this method got called for the same world in the same tick,
the entity would not have been removed from the UUID map, and the
world readd would fail.
This can be triggered even with a plugin if the entity is teleported
twice in the same tick, from world A to B, then back from B to A.
The re-add to A will fail to add the entity to the world. It will
actually be there, but it will not be visible on the client until
the server is restarted to re-try the add to world process again.
This bug was unlikely to be seen by many due to the double teleport
requirement, but plugins (such as my own) use this method to
trigger a "reload" of the entity on the client.
This improves plugins like Citizens that rely on direct instance of Yggdrasil implementations.
Instead of wrapping, directly extend and override the methods.
Went ahead and wrapped all of the services in prep in the base patch, then features modify what they need
Adds ability to control who receives it and who is the source/sender (vanish API)
the standard API is to send the packet to everyone in the world, which is ineffecient.
This adds a new Builder API which is much friendlier to use.
Players are able to use alt accounts and enderpearls to travel
long distances utilizing the pearls in unloaded chunks and loading
the chunk later when convenient.
This disables that by not saving the thrower when the chunk is unloaded.
This is mainly useful for survival servers that do not allow freeform teleporting.
Fires an event anytime an enderman intends to teleport away from the player
You may cancel this, enabling ranged attacks to damage the enderman for example.
Resolves#1101
reporter of this issue was incorrect and did not verify vanilla logic
vanilla logic only skips ticks if the flag is set
spigots change causes bugs as it now skips ticking and processing
chunk teleportation, which was a bug I fixed many many years ago...
