Issue with adding Lightning on a Server

[NoNameGuy]

So I made this mod a while ago where I had an item, that adds a lightningboltentity to whatever block you look. Turns out that it doesn't function properly on a dedicated server. Can anyone tell me what the issue is?

Here is the code:

 

package com.dersichkeinennamenausdenkenkann.somethings.items;

import java.util.List;
import com.dersichkeinennamenausdenkenkann.somethings.SomeMod;
import com.dersichkeinennamenausdenkenkann.somethings.util.helpers.KeyHelpStuff;
import net.minecraft.block.BlockState;
import net.minecraft.client.Minecraft;
import net.minecraft.client.util.ITooltipFlag;
import net.minecraft.entity.effect.LightningBoltEntity;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ActionResult;
import net.minecraft.util.ActionResultType;
import net.minecraft.util.Hand;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.math.RayTraceResult;
import net.minecraft.util.text.ITextComponent;
import net.minecraft.util.text.StringTextComponent;
import net.minecraft.world.World;
import net.minecraft.world.server.ServerWorld;


public class Cross extends Item {


    public Cross() {
        super(new Item.Properties()

                .group(SomeMod.SomethingItemGroup.instance)
                .maxStackSize(1)
        );
    }

    public void addInformation(ItemStack stack, World worldIn, List<ITextComponent> tooltip, ITooltipFlag flagIn)
    {
        if(KeyHelpStuff.isHoldingShift())
        {
            tooltip.add(new StringTextComponent("With this Item, you will be able to summon some dawm sick lightningbolts. But they hurt... Just so you know"));
        }
        else {
            tooltip.add(new StringTextComponent("Hold" + "\u00A7b" + " SHIFT " + "\u00A7f" + "for more Information!"));
        }
        super.addInformation(stack, worldIn, tooltip, flagIn);
    }

    @Override
    public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn){

        if(!(worldIn instanceof ServerWorld)) return new ActionResult<>(ActionResultType.PASS, playerIn.getHeldItem(handIn));

        RayTraceResult lookingAt = Minecraft.getInstance().objectMouseOver;
        if (lookingAt != null && lookingAt.getType() == RayTraceResult.Type.BLOCK) {
            double x = lookingAt.getHitVec().getX();
            double y = lookingAt.getHitVec().getY();
            double z = lookingAt.getHitVec().getZ();

            ((ServerWorld) worldIn).addLightningBolt(new LightningBoltEntity(worldIn, x, y, z, false));
        }
            // not looking at block

        return super.onItemRightClick(worldIn, playerIn, handIn);
    }

    @Override
    public boolean canPlayerBreakBlockWhileHolding(BlockState state, World worldIn, BlockPos pos, PlayerEntity player) {
        return false;
    }
}

 

or is it something other than the lightning that is added?

thanks for your reply. That helps a lot.The only thing I don't understand is that i don't own dersichkeinennamenausdenkenkann.com? What do you mean at that point?
