KnockbackSync
KnockbackSync is a simple PvP plugin that fixes one of the biggest problems in Minecraft combat — ping.
Normally, players with higher ping get delayed knockback, which makes fights feel inconsistent and unfair. KnockbackSync removes that delay and makes knockback feel the same for everyone, no matter their connection.
What it does
No more ping delay
Knockback is applied instantly instead of being affected by latency.
- Hits feel responsive
- No delayed knockback
- Everyone gets the same experience
Consistent fights
Every player takes knockback the same way.
- No advantage for low ping players
- No disadvantage for high ping players
- More skill-based PvP
Server-side handling
Knockback is handled properly on the server instead of relying on the client.
- More accurate hit registration
- Less randomness in fights
- Cleaner overall combat
Adjustable values
You can tweak how knockback feels.
- Change horizontal and vertical strength
- Keep it vanilla or make your own style
- Works for any type of server
Why use it
If your server has PvP, this just makes it better.
No weird delays, no unfair fights — just clean, consistent knockback for everyone.
