FieldAccessException: No field with type double exists in class PacketPlayOutNamedEntitySpawn

[noahcoetsee]

I have attempted to create a basic nicking system in my plugin:

Before I show you my full code, just know that here are the lines causing the error:

namedEntitySpawn.getDoubles().write(0, location.getX());
namedEntitySpawn.getDoubles().write(1, location.getY());
namedEntitySpawn.getDoubles().write(2, location.getZ());

It's clear that PacketPlayOutNamedEntitySpawn contains these: https://wiki.vg/Protocol#Spawn_Player

I don't know where I'm going wrong?

@dmulloy2 :D

Here's the full error:

to me it looks like you are running the server on an outdated version. 16w06a (protocol version 100) changed this over 3 and a half years ago from fixed point ints to doubles. that means, 1.8 still has integers, while anything newer uses doubles.

protocollib behaves as expected.

in the future: please fill out the issue template, it contains important stuff needing to debug any issues. having the server version would have made this way more obvious.

Ok, my apologies.
