Hey guys, new small update dropped.
It's not a major update but a lot of improvements were made to potion behavior. Now potions are completely configurable and can emulate 1.8.8 behavior perfectly. Currently this is how potions sub-config looks like:

!! MAJOR UPDATE 2.0 !!

Hello my friends, the new major update dropped bringing plenty of new features and bug fixes.

Plugin is now native to 1.21. And we removed support for 1.18 due to drastic packet changes.
Also the name of the plugin changed to ModernCombat (formerly ModernKnockback)

New features:

Block-hitting / Sword Blocking (1.21.4+ only)
With the new minecraft update it's now possible to bring back block hitting like it was in 1.8.8. We're using NBTEditor and ProtocolLib to make this possible. It's also possible to modify how much damage you'd like to block when player is blocking with a sword.
Legacy Mechanics
Legacy mechanics such as legacy tool damage, legacy potions, off hand disabling, elytra disabling, lapis enchanting, legacy burn delay, legacy health regen, legacy saturation, legacy armor, legacy projectiles etc...So there's no need to use other plugins to achieve this anymore!
Better Spectator System
This is extremely useful for minigame servers who don't want to create custom spectator mode but also don't want people to teleport or have no-clip when they're in Gamemode.SPECTATOR. We fixed it using packets. Players in spectator mode now won't be able to go through blocks, can't teleport to players and can interact with inventory items!
Anti-Glitch Pearls
Implementation of anti-glitch pearls to modern versions.
Fast Crystal
Using packets we allow users to place and destroy crystals much faster, that allows users to place them rapidly
Knockback-Sync (Beta)
Implementation of knockback-sync system that is latency agnostic to our Knockback system. Will result in the same knockback despite the users latency or any other factors. This is still in beta and bugs can occur. It's our own implementation of this feature.
Module for item behaviors
Items like shields, end crystals, respawn anchors, totems are completely configurable now and can be modified to fit your specific needs. For example custom explosions, custom explosion damage, shields can be disabled by arrows, fishing rods.
Cooldown system
Completely configurable cooldown system with 3 presets for god apples, enderpearls, totems (can be removed). Can be modified in cooldown.yml to add new cooldowns.
New Legacy Swimming mode
Now you can enable legacy swimming to disable the swimming animation. We use packets to achieve this so it's completely safe server-side.
Configurable critical hits
We've made it so criticals hits are completely configurable and we removed old criticals from the game
And much more! Check and see.

Improvements and bug fixes:

Bedrock aim assist now uses packets to change yaw and pitch of the user. player#setRotation was unstable and didn't work correcly.
Improved the bow boosting logic.
Improved GUI. Now the plugin knockback is completely GUI based!
Improved Server Side Hit Detection packet handling.
Added fishingRod specific knockback configuration options for knockback system.
Plugin now uses Dependency Injection and Automatic dependency installation to drastically reduce file size and improve buyer experience.
New lag compensation mechanism for knockback sync and hit detection.
Old sound effects (removed new combat attack sounds)
Removed DRM.
And much more. Check and see!

----------, Mar 7, 2025

Plugin now follows Spigot's ToS and new GUI system

Quick update that now plugin follow SpigotMC's strict ToS when it comes plugin anti-piracy.

Also added the new GUI system. Now /knockback command has a new gui system if not arguments are presented. This is still under development and testing. But let me know if everything works as intended. If any small bugs appear I'll fix them asap.

Also added a few new features!
1. Old Combat system and it's completely configurable!

2. Silent Aim for bedrock users.
- This is a feature that was requested by one customer and I liked the idea so I decided to add it! Basically like in modern games (like fortnite) there is silent aim for console and mobile players. With this plugin you can now also get silent aim assist for bedrock players who are mobile and consoles!
3. 1.21 support

----------, Jul 31, 2024

Large update

I've added and changed quite a lot of things internally. Fixed bugs that were reported on my support discord.
Added beta knockback profiling system and worldguard support for the same.
Extended the API features so now you can modify the knockback of the player through the API function: ModernKnockbackAPI#changeKnockback(UUID playerUUID, String knockbackName). This is very useful for people who want to incorporate modernknockback in their system like practice or pvp plugins.
Many more features that I forgot to remember.
