yeah, like the double interact

here's a list
- Can trigger twice
- Sometimes does not trigger
- The way around it (ArmAnimationEvent) cannot distinguish left and right click

It triggering twice isn't a bug. It's called for each hand and you have to account for that :p
That's very much intentional

@opal carbon
Basically, I'll try to make this less complicated. InventoryType is really a combination of two things. 1. an inventory which only stores items. 2. a Container aka MenuType which is what is displayed to the player. As you might imagine this is really fucking amibguous. If you're curious what can be expressed just look here
https://hub.spigotmc.org/stash/users/y2k_/repos/bukkit/browse/src/main/java/org/bukkit/inventory/MenuType.java?at=refs%2Fheads%2Fcontainer-api
opal carbon
ah okay
river oracle
for example InventoryType.CRAFTING which is the players inventory can't be opened, neither can the CreativeMenu those are client side only
river oracle
ah okay
https://hub.spigotmc.org/stash/users/y2k_/repos/bukkit/browse/src/main/java/org/bukkit/event/inventory/InventoryType.java?at=refs%2Fheads%2Fcontainer-api even more showing each InventoryType that is associated with a MenuType will have a non null enum parameter
slender elbow
well, there is a registry for the creative menu nowadays π
it isn't network synced, but maybe one day
one can hope
young knoll
There are many registires I would rather have first :p
opal carbon

CraftInventoryCustom isn't NMS its a terrible patch job for a bad api

you don't pass a title when making an Inventory with my change, and if you do CraftInventory handles the legacy createInventory and assigns the title

eternal night
thing always worring about the "lets do virtual entities by just reusing the entity interfaces" is the general assumption that held till now that well, you should only really have an instance of Entity if it is alive and well
so plugins doing wild stuff with that "premise" are gonna get fucked
young knoll
There is world.createEntity iirc
It shoudln't break plugins too much
Since they likely will never recieve a virtual entity
eternal night
Yea I mean that is kinda the gamble π
young knoll
I'm trying to think how they would get it
eternal night
I mean, API ?
young knoll
Ah
slender elbow
plugin D passes it to N
eternal night
its not gonna run into it from world querring yea
young knoll

eternal night
Well like, Entity still exists
young knoll
Yes
eternal night
The somewhat implicity contract of the entity type is the one that is getting mutated
retconned into existence that it can also represent an entity that is not in a world
young knoll
So far I haven't seen any issues from mutating virtual entities
eternal night
Well yea most things should be fine, hopefully ?, that just needs a lot of going through methods
lilac dagger
i mutate some parts of my nms entities no problem
it depends tho on some methods that might require the entity to be bound to a world
young knoll
I suppose I could probably remove the virtual entity part altogether and just rely on snapshots
idk
young knoll
it depends tho on some methods that might require the entity to be bound to a wo...
it is
Entity is always bound to a world, just might not be spawned in said world
eternal night
idk, I mean, there is 100% a need for something along the line of a fully fledged interface for setting this
snapshot is useful too 100%
actually, wait let me see what your snapshot concept was xD
eternal night
e.g. fun side question, what happens with addPassanger ?
young knoll
On a virtual?
eternal night
yea
young knoll
Not too sure yet
I imagine a virtal passenger on a virtual works as one would expect
young knoll
True
eternal night
which, if no, I guess that is fine maybe ?
If yes, oh god now we have virtual entitys in an event
now we don#t even need plugin A to pass to plugin B
eternal night
young knoll
Although it may just be fine for old plugins to recieve virtual entities
If they behave the same
I need to remember to make that jira ticket for direct byte serialization of certain objects

Emily's a network developer I can tell
young knoll
Plus direct nbt serializtion can work on stuff that isn't ConfigurationSerializable
eternal night
Sure, idk its introducing a new binary format to the API
those are always fun
and people tend to go over board
doesn't paper have a fucking PDC to blob method ?
slender elbow
i mean they're just different formats, e.g. with jvm serialization you can have cyclic references, A has field B has field A, if you throw something like that to a CompoundTag it'll blow up lol
eternal night
Yea idk, I mean you can certainly throw a bunch of random toByte helpers everywhere, that is pretty much just what paper does
or you can dream up a new way to serialise stuff
which might be nicer down the line maybe but maybe not
