[1.19.4] warden sonic boom shooting sword, issue with particles

Recommended Posts


i'm trying to make a sword that when used, fires a sonic boom (the one the warden makes) in the direction the player is facing, dealing damage in the process.

my current code is able to create particles, but it only creates one, at the location of the player. also, i'm not sure how to damage the enemies caught in the boom. previously, i used AABB to find the targets, but as far as i know, it only works with cubes, not lines. if you could give me a hand on either, i would really appreciate it.

my code:

package net.grandfish.mod.item.custom;

import net.minecraft.core.particles.ParticleTypes;
import net.minecraft.network.protocol.game.ClientboundLevelParticlesPacket;
import net.minecraft.server.level.ServerPlayer;
import net.minecraft.world.InteractionHand;
import net.minecraft.world.InteractionResultHolder;
import net.minecraft.world.entity.LivingEntity;
import net.minecraft.world.entity.player.Player;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.item.Tier;
import net.minecraft.world.level.Level;
import net.minecraft.world.phys.Vec3;

public class WardenSwordItem extends LightningSwordItem {
    public WardenSwordItem(Tier pTier, int pAttackDamageModifier, float pAttackSpeedModifier, Properties properties) {
        super(pTier, pAttackDamageModifier, pAttackSpeedModifier, properties);

    private void locateTargetExecute(LivingEntity player, Level level, InteractionHand hand) {
        if (!level.isClientSide()) {
            Vec3 pos = player.getEyePosition(1.0f);
            Vec3 dir = player.getLookAngle();

            for (int i = 0; i < 40; i++) {
                Vec3 particlePos = pos.add(dir.scale(i));
                level.addParticle(ParticleTypes.SONIC_BOOM, particlePos.x(), particlePos.y(), particlePos.z(), 0.0, 0.0, 0.0);

            ClientboundLevelParticlesPacket particlePacket = new ClientboundLevelParticlesPacket(
                    (float) pos.x(),
                    (float) pos.y(),
                    (float) pos.z(),
            ((ServerPlayer) player).connection.send(particlePacket);
    public InteractionResultHolder<ItemStack> use (Level level, Player player, InteractionHand hand){
        if (!level.isClientSide() && hand == InteractionHand.MAIN_HAND) {
            locateTargetExecute(player, level, hand);
            player.getCooldowns().addCooldown(this, 40);
        return (super.use(level, player, hand));

thank you for taking a look at my post ❤️

I mean, you could use AABB to target people in the relevant range and then check if the entity is in front of the player. Since you know the player's y rotation, you can just check if the entity direction vector is between two vectors that make up your field of view.

    • Make a test without practical_plushies_mobs, practical_plushies_animals and dark-waters - looks like it is not working with sinytra connector

    • Maybe your file codes are missing. Therefore it is crashing.
    • I've been trying to make a mod pack for the last day or so now and I haven't been able to launch it once even with all mods disabled. It keeps showing up with Exit Code 1. I gave the modpack to a friend to try and it didn't launch on their pc either due to the same exit code, so I'm not entirely certain what the problem is or how to check it in the logs. So far I've attempted: - Changing from forge version 43.3.0 to 43.3.5 - Downloading Java - Disabling mods (both entirely and individually) I have an NVIDIA GeForce GTX 1070 driver, and I haven't tried to uninstall or reinstall it yet because I'm not certain how to and would have to mess anything up further. I have the latest .txt file of the crash report here: [16:24:34] [main/WARN]: Failed to add PDH Counter: \Paging File(_Total)\% Usage, Error code: 0xC0000BB8 [16:24:34] [main/WARN]: Failed to add counter for PDH counter: \Paging File(_Total)\% Usage [16:24:34] [main/WARN]: Disabling further attempts to query Paging File.
