    • filterEntityProperties

      @Nonnull private static SEntityPropertiesPacket filterEntityProperties(SEntityPropertiesPacket msg)
      Filter for SEntityPropertiesPacket. Filters out any entity attributes that are not in the "minecraft" namespace. A vanilla client would ignore these with an error log.

    • filterCommandList

      @Nonnull private static SCommandListPacket filterCommandList(SCommandListPacket packet)
      Filter for SCommandListPacket. Uses CommandTreeCleaner to filter out any ArgumentTypes that are not in the "minecraft" or "brigadier" namespace. A vanilla client would fail to deserialize the packet and disconnect with an error message if these were sent.
