Knockback Optimizer
How it works.
Predicts knockback client-side so hits/explosions look instant instead of delayed by ping.
Applies armor/shield/attributes (Blast Prot, Feather Falling, Knockback Resistance) to scale the predicted result closer to vanilla.
Presets swap many settings at once: Extreme = most accurate/heaviest, Super Lite = fastest/least accurate.

Now the visuals aren't perfect but they certainly do look pretty close to what it should look like, I do plan on updating the mod to improve it and you can always tweak the settings to find whats perfect for you
Is this allowed on servers? I don't know, it should be perfectly fine since it's just a visual client side mod and doesn't actually offer any advantages, Just make sure to check with the server before using it. and just dont test with it
Requires YACL and Mod Menu
