Exception when trying to read the entity metadata (1.19.3)
Brokkonaut opened this issue · 4 comments
I am not sure if I use the api correctly, I tried to modify the entity metadata in the ENTITY_METADATA packet in 1.19.3, so I tried to get the values like this
List<WrappedDataValue> watchables = packet.getDataValueCollectionModifier().read(0);
but i get the following exception:
java.lang.IllegalArgumentException: handle (net.minecraft.network.syncher.DataWatcher$Item@45339ee7) is not a class net.minecraft.network.syncher.DataWatcher$b, but class net.minecraft.network.syncher.DataWatcher$Item

Thanks for the code snippet. I'm attempting to resolve this entity metadata packet change in this Spigot thread, unfortunately I have been unsuccessful so far. I'm intercepting packets, not sending them, so I couldn't understand how to transfer the goods of the code snippet across.
Edit: check this thread for the solution :)
Not sure what you're doing exactly, for reference how deal with meta in 1.19.3 (and only 1.19.3), see:
Thanks. Changing from packet.getWatchableCollectionModifier().read(0) to packet.getDataValueCollectionModifier().read(0) fixed my issue.
