Hello. I cant figure out how to open a custom gui ex: GuiTest.class  on item right click. I have tried many steps so please help.

Look at the forge wiki for gui handling, you need to return an instance of your gui in your IGuiHandler.getClientGuiElement()

I really cant figure this out for the life of me.

This is my item class

package mods.cyphereion.MagicSwords;

import java.util.List;

import net.minecraft.client.gui.GuiMultiplayer;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class RecipeBook extends Item {
private ItemStack info;
private int index;
public RecipeBook(int par1)
{

	super(par1);
	this.setMaxStackSize(1);
	this.setCreativeTab(Core.tabMagicSwords);
}

public boolean hasEffecct(ItemStack par1ItemStack){
	return true;
}

public void addInformation(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, List par3List, boolean par4)
{
	//par3List.add("Use me to see the avaliable recipes. ");
	par3List.add("Work In Progress.");
}

public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer entityplayer, int x, int y, int z){
	return null;

 }

 

 

And this is my guihandler:

package mods.cyphereion.MagicSwords;

import net.minecraft.client.gui.Gui;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;
import cpw.mods.fml.common.network.IGuiHandler;

public class RecipeBookGuiHandler implements IGuiHandler{

@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
	 {
		  
		  if (!world.isRemote)
		        {
		            player.openGui(RecipeBookCore.instance, 0, world, x, y, z);
		            return true;
		        }

		        return true;
		 }
}

@Override
public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
	 {
		  
		  if (!world.isRemote)
		        {
		            player.openGui(RecipeBookCore.instance, 0, world, x, y, z);
		            return true;
		        }

		        return true;
		 }
}



}

you need to change

public ItemStack onItemRightClick(ItemStack i, World w, EntityPlayer e, int x, int y, int z){
e.openGui(yourMod.instance, guiId, w, x, y, z)  
return i;//If you return null the itemstack is set to null
}

also hasEffect is spelled wrong... that'll give you some issues down the road. use @Override annotations to prevent this and make updating easier
