For testing purposes I've been writing a mod that dynamically generates custom items with an attached string based on a configuration file. The intention is allowing a player to run a command (eventually on a given creature, tile or chunk) by using the custom item; currently I've got it so the custom items spit out text from a configuration file.

 

However, when I try to use this to run a command (EG. '/summon Sheep ~ ~ ~ {CustomName:Magic Sheep}' - which works when used from chat by the player) it still just outputs the text to chat rather than attempting to do it as if the wielding player had typed it out themselves. Is it possible to do this?

 

Here's the code for the custom items as I have it currently:

 

package org.nationsatwar.magictestingwands.items;

import net.minecraft.client.Minecraft;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ChatComponentText;
import net.minecraft.world.World;

import org.nationsatwar.magictestingwands.MagicWands;

import cpw.mods.fml.common.registry.GameRegistry;

public class ItemMagicWand extends Item 
{	
private String command = "";

public ItemMagicWand(String name, String newCommand)
{
	setUnlocalizedName(MagicWands.MODID + "_" + name);
	setTextureName(MagicWands.MODID + ":" + "magicWand");
	GameRegistry.registerItem(this, name);
	setCreativeTab(CreativeTabs.tabMisc);

	command = newCommand;
}
public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
{
	par2World.playSoundAtEntity(par3EntityPlayer, "random.orb", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));
	ChatComponentText msg = new ChatComponentText(command);
	if(!par3EntityPlayer.worldObj.isRemote)
	{
		Minecraft.getMinecraft().thePlayer.addChatComponentMessage(msg);
	}
	return par1ItemStack;
}
}

I don't know the issue, but in the

onItemRightClick()

method, you are checking if you are on the server side, and if so, you acces the client player. You need to use the EntityPlayer parameter.

That did it, diesieben. Thank you very much.
