KnockbackSync

The fabric version currently does not fully represent what Knockback Sync should look like.

It is an improvement upon Vanilla KB but it is currentlly inferior to the bukkit version

Players who want the proper experience should test using a Bukkit/Spigot/Paper/Purpur/Pufferfish server instead until further notice.

Tired of inconsistent knockback ruining your PvP experience? Our plugin recalculates knockback as if it were done clientside, leveling the playing field and ensuring every player enjoys a fair fight, no matter their connection quality.

Minecraft doesn’t factor in network latency when determining a player's actions on the server. This causes the server to receive outdated information that doesn’t reflect the player's clientside position, leading to varying knockback effects based on connection quality.

This plugin intercepts and adjusts knockback calculations to match what would occur clientside, effectively mitigating the disadvantages caused by high latency. By synchronizing knockback handling, we ensure that players experience consistent and fair knockback, providing a balanced and competitive environment for all."

Frequently Asked Questions (FAQ)

Does this change put high ping players at a disadvantage?

It depends on the player. Some may notice a difference if they're used to relying on high ping to reduce knockback. For others, it could actually be an advantage.

How do I change the ping offset?

Open up config.yml and edit the line that says ping_offset: 25. Replace 25 with your desired ping offset.

Then just type

/knockbacksync reload

or restart your server.

What version should I download?

Alpha builds automatically built straight from the source as soon as changes are uploaded. They may not always be tested. We recommend these if you need a new feature (such as support for your platform or version) or want to help with development of the this mod/plugin and testing.

Beta: These builds are manually tested by developers. They are not guranteed to have no regressions and have not seen extensive use to verify that they work. We recommend these if you are not afraid of potentially having to deal with a breaking bug or two.

Release builds have been tested by the wider community on various servers. These builds are released periodically and are gauranteed to be stable. Any issues in release builds will be patched immediately. They are intended for large production servers that need absolute perfect stability and where the chance of a bug in this plugin is too high of a cost to bear. Users that value stability should use this.

• If a pong packet has not been received: "Pong not received. Your estimated ping is [estimated ping]ms." or "Pong not received. [Player]'s estimated ping is [estimated ping]ms."
