So, I'm working on my first ever mod, and I'm having a bit of trouble. I'm trying to make it so that when I right-click with a certain item in hand while looking at water, it turns into ice. The trouble I'm having is that I can't figure out how to detect that I'm looking at water. I can detect other blocks just fine, but not liquids. Here's the code for the item class:

 

package com.me.modName.items;

 

import java.util.List;

 

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.init.Blocks;

import net.minecraft.item.Item;

import net.minecraft.item.ItemStack;

import net.minecraft.util.BlockPos;

import net.minecraft.util.EnumFacing;

import net.minecraft.world.World;

import net.minecraftforge.fml.relauncher.Side;

import net.minecraftforge.fml.relauncher.SideOnly;

 

public class ItemName extends Item {

 

@Override

public boolean onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumFacing side,

float hitX, float hitY, float hitZ) {

if (worldIn.getBlockState(pos) == Blocks.water.getDefaultState()) {    // This works if I change it to

worldIn.setBlockState(pos, Blocks.ice.getDefaultState());            // a solid block like sand

}

 

return false;

}

}

 

Try looking into ItemBucket to see how that does it.
