Custom KB

[vestal jetty]

What this does is that it modifies the KB of the players to try to assimilate the KB with servers. It is not the best but it works well

import { world, Player } from '@minecraft/server';

const config = {
    horizontalKB: 0.2789,
    verticalKB: 0.1023
};

world.afterEvents.entityHitEntity.subscribe((event) => {
    const attacker = event.damagingEntity;
    const victim = event.hitEntity;
    
    if (!(attacker instanceof Player)) return;
    if (!attacker || !victim) return;

    const attackerLocation = attacker.location;
    const victimLocation = victim.location;

    let knockbackX = victimLocation.x - attackerLocation.x;
    let knockbackZ = victimLocation.z - attackerLocation.z;

    const magnitude = Math.sqrt(knockbackX * knockbackX + knockbackZ * knockbackZ);
    if (magnitude !== 0) {
        knockbackX /= magnitude;
        knockbackZ /= magnitude;
    }

    let horizontalKB = config.horizontalKB;
    let verticalKB = config.verticalKB;

    const horizontalForce = {
      x: knockbackX * horizontalKB,
      z: knockbackZ * horizontalKB
    };

    victim.applyKnockback(horizontalForce, verticalKB);
});

Any suggestion will be gladly accepted as well as a good config if you find one.

That s good

[wispy citrus]

where those number coming from

[vestal jetty]

I got the numbers by testing with another player to find a good configuration.

[bright lantern]

can it be used to emulate the Java kb system?

[hushed sonnet]

The point is that its similar to hive knockback

But yes it can be you’ll just need to configure the numbers enough to do so

@vestal jetty Bro U are so kind!!! I'm also trying to make and looking for it but I can never achieve the effect I want ,you are helping me so big!!!

[vestal jetty]

It doesn't replicate it, I think for now it's difficult not to say impossible to replicate it.

this is great however you could use entityHurt since entityHitEntity is kind of weird. It registers hits so people could click up to 10-20 clicks per second. So its registering all those values as KB in those clicks, rather than registering the KB per entity hurt.
I haven't tested the code myself tho so idk how it looks like, overall it looks good!

[nocturne spindle]

I just want a low KB,but it is so hard to get the best effect without plugin

[deep narwhal]

Heyyy! can somebody help me, I have a question about knockbakc, I am making an addon and want if you get the tag knockback, that you get pushed into the air for 10 block, then the tag removes, can somlebody help me? Thanks!

[deep narwhal]

it's fixed!

[lunar silo]

anyone know how to stop them from going so far back i was testing it on a zombie

[vestal jetty]

edit horizontalKB

Edit horizontalKB for pushback

And vertical KB is for upward thrust

[vestal jetty]

.

[lunar silo]

I do but no matter what I change there isn’t a difference

[lunar silo]

Am I doing it wrong?

[vestal jetty]

There may be a mistake

    const horizontalForce = {
      x: knockbackX * horizontalKB,
      z: knockbackZ * horizontalKB
    };

    victim.applyKnockback(horizontalForce, verticalKB);

[vestal jetty]

Remove the previous applyKnockback and place this new one

[lunar silo]

its giving me this error

i added it and removed the line that was an error

[lunar silo]

@vestal jetty

[vestal jetty]

Does it throw an error at you?

If you are testing with a non-player entity, the KB will not apply.

remove this "if (!(attacker instanceof Player)) return;"

@lunar silo

[lunar silo]

Yea the last line errors

[lunar silo]

thers no longer an error since i put in your code

[lunar silo]

it wont work to test on a zombie or nothin?

@vestal jetty

[earnest helm]

i sent u a dm, just check it once :D

[lunar silo]

wasnt really helpful

[earnest helm]

Need me to elaborate?
