Detailed description of a problem

I am trying to debug an issue where when i connect to a proxied server i always initially spawn inside the floor, just to be "teleported" to the correct position microseconds afterwards.

In the flow of packets the client sends the settings -> custom_payload -> held_item_slot -> position_look commands.
While the custom_payload and the settings are expected (although in different order) the other two are kind of unexpected and the position_look command seems to show the issue with the spawning inside the floor:

{ size: 34, name: 'position_look', state: 'play' } { x: 8.5, y: 65, z: 8.5, yaw: -180, pitch: 0, onGround: false }

It is always the same position it seems, at least around that area. The world spawn is nowhere near that position.
I dont really understand why the client is apparently sending its position to the server without even having chunk data at hand.

Although this kind of seems like a client issue, maybe this is triggered by some issue with the packets in the sequence before? Or some missconfiguration on my end?

Connecting to the proxied server (online-mode: false) doesnt show the issue, the client seems to immediately spawn in the correct position. Maybe its just not noticable though…

Someone apparently also noticed the "fallback"

[Robbilie]

It seems holding back even the first clientbound position packet until after the world border was initialized helps

okay now i found the second case where the events emitted are most certainly not in the correct order. is there a way to emit them in the actual received order, synchronize them somehow?

I don't understand what you are saying

nmp is definitely sending packets in order and tcp is delevering them in order

[Robbilie]

I think the event emitter was emitting out if order, or at least it seemed to be that way. I don't quite remember if I am still facing this issue or wether i solved it somehow
