Code

Additional context
None

Still not :c No field with type float exists in class PacketPlayOutLogin

I cant set ther 0x23, so I just set 23 and got https://pastebin.com/yWPxYd17

yeah, 23 is yet another packet :D
0x23 is hexadecimal, that would be 35 in decimal (2*16+3), so please use that

heh, thats interesting.
I bet you use an outdated version of minecraft, right?
one where packet 0x23 is update light, not world particles.
can you try using createPacket with the numerical id instead of the packet?

Thats interesting, cause im using 1.14.4 latest (209) build paperspigot

uuuhm, thats even more interesting. what I though is that protocollib didn't properly remap the packet id.
again, even on 1.14, can you try calling createPacket(0x23), not via the PacketType?
