Game crash when putting my item in my hotbar


Recommended Posts

I made a trident that lets you walk on water when holding it, but everytime I put it in my hotbar my game crashes. This is my code:

package com.kuikenpower.falidsmp.init.item;

import net.minecraft.client.player.LocalPlayer;
import net.minecraft.core.BlockPos;
import net.minecraft.world.entity.Entity;
import net.minecraft.world.item.Item;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.level.Level;
import net.minecraft.world.level.block.Block;
import net.minecraft.world.level.block.Blocks;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.api.distmarker.OnlyIn;

@OnlyIn(Dist.CLIENT)
public class TridentItem extends Item {

	public TridentItem(Properties arg0) {
		super(arg0);
		// TODO Auto-generated constructor stub
	}
	
    @Override
    public void inventoryTick(ItemStack p_41404_, Level world, Entity entity, int p_41407_, boolean p_41408_) {
        LocalPlayer player = (LocalPlayer)entity;
        if(player.getMainHandItem().getItem() instanceof TridentItem) {
			BlockPos pos = player.getOnPos();
			Block blockClicked = world.getBlockState(pos).getBlock();
        	if(blockClicked == Blocks.WATER) {
        	player.setDeltaMovement(player.getDeltaMovement().multiply(1.05, 0, 1.05));
        	if(player.input.jumping) {
        		player.setDeltaMovement(player.getDeltaMovement().add(0, 1, 0));
        	}
        }
    }
    }
}

When using just Player, I can't use .input. How would I be able to not have LocalPlayer but still use .input?

you can not, key input is client side this is why it's only accessible in LocalPlayer,

but the most stuff is server side and will be synced to the client
