MC-135506: Experience should save as Integers
Fix EXP orb merging causing values to go negative - Closes#1169
Add "Safe Regen" Duplicate UUID resolver and make default
After witnessing behavior of the regeneration logs, its clear that Vanilla
has had bugs with saving duplicate entities for a while....
Some entities are saved in multiple chunks, and now we are bringing those duplicates
out that use to never surface.
This mode will analyze if the entity appears to be a duplicate (near the other dupe uuid)
and delete the entity instead.
This should reduce regenerations to entities that are nowhere near each other, and
therefore more likely to be subject to real UUID collisions due to our
previous bug, and therefor should survive the chunk load.
Fixes GH-1295
Non-standard sized portals exacerbate a flaw in the vanilla
portal teleportation adjustment logic.
As a result, an entity can end up slightly inside of the surrounding
portal blocks. In vanilla, this issue is minor and you are adjusted out
as if it never happened. In CraftBukkit and derivatives, the
anti-suffocation behavior activates and players end up teleported on top
of their portals.
This improves the offset so as to keep the issue from ever occurring in
the first place.
Special thanks to CarpetMod who appears to have had this fixed for some
time, and has licensed their code such that we can use it as needed.
Due to the changes in 1.13, clients will send a tab completion request
for all bukkit commands in order to factor in the lack of support for
brigadier and provide backwards support in the API.
Craftbukkit, however; has moved the chat spam limiter to also interact
with the tab completion request, which while good for avoiding abuse,
causes 1.13 clients to easilly be kicked from a server in bukkit due
to this. Removing the spam limit could cause issues for servers, however,
there is no way for servers to manipulate this without blindly cancelling
kick events, which only causes additional complications. This also causes
issues in that the tab spam limit and chat share the same field but different
limits, meaning that a player having typed a long command may be kicked from
the server.
Splitting the field up and making it configurable allows for server owners
to take the burden of this into their own hand without having to rely on
plugins doing unsafe things.
This patch has been applied to 1.12.2 in order to allow people using
plugins which allow clients of newer versions to connect, this is
not a common practice, however is being done as a level of nicety
given the current status of 1.13
We have a result boolean for this already, and this
method was meant to be "Try from cache, if that fails, look it up"
So NPE'ing there just wasn't correct.
In 1.13 the method previously used now returns translatable keys.
`block.minecraft.cobblestone` instead of `Cobblestone`
We just need to make sure we're translating those keys.
ideally this should of never mattered, as it will only
be hit if you teleport out of an unloaded chunk...
But apparently some people are triggering this.
See #1223
No entities were lost in this bug, just we were triggering the add entities
before they were loaded due to an inconsistent order of putting chunk into chunkmap.
Any entity that appeared to be gone on the last build will now be back.
This should not ever be used in production!!
This setting is intended for testing so you can try out converting your world
without actually modifying the world files.
This will add some additional overhead to your world, but you're
just testing anyways so that's not a big deal :)
Will store in a folder named after the current version.
PlayerData and Data folders are copied on server start, so there
may be some delay there, but region files are only copied on demand.
This is highly experiemental so backup your world before relying on this to not modify it
1.13 undesirably changed behavior here that chunk load event fired
before the entities were added to the world.
This means any plugin that spawns entities in chunk load event
causes the entities to be registered to the chunk, and then
added to the world twice.
Moves Entity Add to World to be done anytime a chunk is
registered to the Chunk Map, and ignore other calls.
Fixes#1288
* master:
Always process chunk registration after moving
Always move Entity to its new Chunk even if unloaded
If Entity is added to chunk, look up the chunk if current isnt set
Ignore Dead Entities in entityList iteration
Always process chunk removal in removeEntity
Spigot 1.13 checks if any field (which are manually copied from the ItemStack's "tag" NBT tag) on the ItemMeta class of an ItemStack is set.
We could just check if the "tag" NBT tag is empty, albeit that would break some plugins. The only general tag added on 1.13 is "Damage", and we can just check if the "tag" NBT tag contains any other tag that's not "Damage" (https://minecraft.gamepedia.com/Player.dat_format#Item_structure) making the `hasItemStack` method behave as before.
Check the `ItemMetaTest#testTaggedButNotMeta` method to see how this method behaves. (I also added some extra tests).
`hasItemMeta()` will return true if `ItemStack.getDamage() != 0` or it has the `Damage` tag or any other tag is set.
Closes#1222
This will help guarantee that entities are always in the
chunk that they are currently located at.
Should hopefully also fix Citizens triggering the "Saved to wrong chunk" message
Vanilla logic here would allow us to remvoe an entity from
its current chunk, and if it was going to move into an unloaded
chunk, that entity would not be added to the unloaded chunk.
This is bad because this will result in the entity being lost!
In almost all cases, the chunk will be loaded, but in the event
it wasn't, instead of losing the entity, load the chunk to add
the entity to it.
Hopefully will (f)ix #1280...
I'm suspicious that Citizens isn't calling things in the same order and causes the current
chunk to not be set, which then bugs removals. Though this doesn't make any sense to me,
so this likely won't fix it...
But if the isAddedToChunk is true, we really should be returning a chunk anyways if its loaded.
