How do I make an item only do something if the player typed something in chat fi


Recommended Posts

rst?(this was for the title)  I am currently making a 1.7.2 Harry Potter mod and need some assistance with the spells.  I currently am using only one wand on this version.  The code is as follows:


My Wand Class



package net.pottercraft.mod.items.wands;


import cpw.mods.fml.relauncher.Side;

import cpw.mods.fml.relauncher.SideOnly;

import net.minecraft.client.renderer.texture.IIconRegister;

import net.minecraft.creativetab.CreativeTabs;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.entity.projectile.EntitySnowball;

import net.minecraft.init.Items;

import net.minecraft.item.Item;

import net.minecraft.item.ItemStack;

import net.minecraft.world.World;

import net.pottercraft.entity.spells.Baubillious;

import net.pottercraft.entity.spells.Confringo;

import net.pottercraft.mod.PotterCraft;


public class AcaciaWand extends Item {


  public AcaciaWand() {





public void registerIcons(IIconRegister iconRegister) {

this.itemIcon = iconRegister.registerIcon(PotterCraft.modid + ":" + this.getUnlocalizedName().substring(5));



  public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)


  if(par3EntityPlayer.capabilities.isCreativeMode || par3EntityPlayer.inventory.consumeInventoryItem(Items.redstone)) {

  par2World.playSoundAtEntity(par3EntityPlayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

  if (!par2World.isRemote)


          par2World.spawnEntityInWorld(new Baubillious(par2World, par3EntityPlayer));




      return par1ItemStack;






My Spell Class



package net.pottercraft.entity.spells;


import net.minecraft.entity.EntityLivingBase;

import net.minecraft.entity.effect.EntityLightningBolt;

import net.minecraft.entity.projectile.EntityThrowable;

import net.minecraft.util.MovingObjectPosition;

import net.minecraft.world.World;


public class Baubillious extends EntityThrowable {


public Baubillious(World World) {




public Baubillious(World World, double d1, double d2, double d3) {

super(World, d1, d2, d3);



public Baubillious(World par1World, EntityLivingBase arg1EntityLivingBase) {

super(par1World, arg1EntityLivingBase);




protected void onImpact(MovingObjectPosition par1MovingObjectPosition) {


EntityLightningBolt entitylightningbolt = new EntityLightningBolt(worldObj, posX, posY, posZ);

        entitylightningbolt.setLocationAndAngles(posX, posY, posZ, rotationYaw, 0.0F);








The code works fine I just need some assistance towards casting.  [glow=red,2,300]I want the Player to type the 'spell' in chat and then right click to cast.[/glow]  This is one main piece I need help with.

You didn't show your spell class, you have the wand class in there twice.


Second, the wand's right-click function makes no attempt to check to see if anything was said in chat.


Third, your thread title is not useful.  You should name your thread something that corresponds to your problem, like "How do I make an item only do something if the player typed something in chat first?"

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.

Thank you I will fix the code.

You will need a command to make the "type in chat" work. Then store whatever was typed into the player with an IExtendedEntityProperties. Then on right click you can check what was typed.

But just so you know: This is a horrible design choice. Chat should not interact with in-game elements. It breaks the 4th wall or however you would call that.


Is there a better way to do it then?  Like a toolbar for spell selection on the side of the game?

Problem with this design is the fact that one can cast spell with writing actual command on chat, but the other could install some client-side mod that allows him to have macros which gives him auto-cast.


Consider having Customizable KeyBindings that on press are sending packet that changes value in players IEEP for some ticks (and make --ticks). You could also do it other way around - When KeyBinding is Pressed it sends packet to server, and IF you are holding given item the spell is being cast and redstone is consumed. That would save you --tick and another variable to save per spell.

KeyBindings are all over google.

1.7.10 is no longer supported by forge, you are on your own.

    • I am in such a mess. I have lost over 4.7m due to a scammer... It started as bank wires and then bitcoin. it is hard to imagine but it is true and can send any proof, then I tried to use a couple of recovery companies and was as well. Graphic design has been more than just a hobby for me since high school—it has become a thriving career. Starting in my parents' garage, I eventually expanded to my office, running a successful graphic design business. However, like many, I faced the need to diversify my investments due to inflation. This led me to invest 60.16 in Bitcoin, a decision that paid off handsomely as my investment grew to 4.7m over time. This financial windfall allowed me to upgrade my equipment and take on more ambitious projects, furthering the growth of my business. Unfortunately, my excitement was abruptly cut short when I fell victim to a hacking incident. Malware infected my computer, giving hackers access to my Bitcoin wallet. The devastation of potentially losing all my hard-earned savings and plans weighed heavily on me. At this dire moment, a fellow designer suggested Linux Cyber Security Company as a potential solution. Desperate for a lifeline, I reached out to them, hoping for a miracle. The response from Linux Cyber Security Company was prompt, incredibly professional, and effective. Their team quickly traced the hacker’s activities and recovered most of my funds, alleviating a significant amount of stress and uncertainty. Beyond the recovery, they took the time to educate me on essential practices to secure my Bitcoin holdings better. They emphasized using antivirus software to prevent malware infections, avoiding suspicious downloads, and the added security provided by hardware wallets. This experience served as a critical wake-up call for me. It highlighted the vulnerabilities inherent in digital assets and underscored the importance of robust security measures. Thanks to the guidance and expertise of Linux Cyber Security Company, I now feel more equipped to protect my digital assets proactively. Their insights have empowered me to implement stronger security protocols in my business operations and personal finances alike. With my Bitcoin funds securely recovered and a newfound understanding of digital security best practices, I am more confident in navigating future challenges. This journey has reinforced my commitment to safeguarding my hard-earned assets and leveraging technology responsibly. I am optimistic about the growth opportunities ahead, creatively in graphic design and prudently in investment strategies. In conclusion, while the hacking incident was a setback, it ultimately became a catalyst for enhancing my digital security awareness and resilience. I am grateful to Linux Cyber Security Company for their expertise and support during a challenging time, enabling me to continue pursuing my passion for graphic design with renewed confidence and financial stability.
