Enable the ability to view sent packets between the client and the server in a separate file. We used this plugin in the sense that it will be useful, and rather important for many developers using packages. Presumably, it is necessary to write anti-reading - it will be very useful here.
All you need is ProtocolLib, Paper and version 1.21 (Support 1.20, but I have not checked)
Using it in this example (probably ha-ha):
- The player cannot open the chest, most likely he has a "Bug" or "ping (Internet freeze)". The admin will most likely advise to re-enter, check the Internet and all that. With the plugin, everything will be simpler, because you can describe the problem in 15 seconds using the command /packets start IvanIvanov USE_ENTITY, then in the file IvanIvanov_USE_ENTITY_1.log to record information (but of course it will be necessary to select an action, such as: a packet to the chest, we see that the packet from the player comes, but the server does not respond with an OPEN_WINDOW packet) so the diagnostics will last for a short time and we will understand that the PLUGIN is happening, not the PLAYER
