I'm trying to make a book like that of Thaumcraft and Mystcraft that you right-click the item and it opens a gui that I later will have a functionality such as controls for a machine receptacle. I am fairly new to modding minecraft and I know a decent bit of java but this is completely dumbfounding me. I have got it so far to have the item class, but I cant get a gui to appear on right-click

 

This is my item class

 

package archangel.necromancy.item;

 

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.item.ItemStack;

import net.minecraft.world.World;

import archangel.necromancy.Necromancy;

import archangel.necromancy.lib.GuiIds;

import archangel.necromancy.lib.Strings;

 

public class ItemNecronomicon extends ItemNC {

 

    public ItemNecronomicon(int id) {

 

        super(id);

        this.setIconCoord(0, 0);

        this.setItemName(Strings.NECRONOMICON_NAME);

        this.setCreativeTab(Necromancy.tabsNecro);

        maxStackSize = 1;

       

    }

    public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer player)

    {

        player.openGui(Necromancy.instance, GuiIds.NECRONOMICON, world, 0, 0, 0);

        return itemstack;

    }

}

 

 

My ItemNC class

 

package archangel.necromancy.item;

 

import net.minecraft.item.Item;

import archangel.necromancy.lib.Reference;

import archangel.necromancy.lib.Sprites;

 

public class ItemNC extends Item {

 

    public ItemNC(int id) {

 

        super(id - Reference.SHIFTED_ID_RANGE_CORRECTION);

        maxStackSize = 1;

        setTextureFile(Sprites.SPRITE_SHEET_LOCATION + Sprites.ITEM_SPRITE_SHEET);

        setNoRepair();

    }

 

}

 

 

 

ModItems

 

package archangel.necromancy.item;

 

import net.minecraft.item.Item;

import archangel.necromancy.lib.ItemIds;

 

public class ModItems {

 

    /* Mod item instances */

    public static Item necronomicon;

    public static void init() {

 

        /* Initialize each mod item individually */

        necronomicon = new ItemNecronomicon(ItemIds.NECRONOMICON);

 

//        necronomicon.setContainerItem(necronomicon);

 

    }

}

 

 

 

I have figured that I need to make a GuiScreen class since I can't use tile entities for an item. I have been looking at the GuiScreenBook.class but I cannot make much sense out of it where I get a usable result. I have been google'ing solutions for a while now and either I am doing it wrong or I can't find anything other than GUI's for blocks. I would prefer guidance as to what to do/look for instead of handouts. I appreciate any help and advice. Thanks

change

 

 

player.openGui(Necromancy.instance, GuiIds.NECRONOMICON, world, 0, 0, 0);

 

 

to

 

 

player.openGui(Necromancy.instance, GuiIds.NECRONOMICON, world, player.posX, player.posY, player.posZ);

 

 

also make sure you arent giving the wrong instance of your mod

That doesn't seem to work I am still not having any gui's pop up on rightclick. I'm fairly sure I am using the correct instance, but how would I tell for sure?

This is my main class file

Okay I figured some of this out and I now have a GUI appearing on right click, but how would I do this without mod loader?

        maxStackSize = 1;

    {

return itemstack;

Any help? I would prefer to not have any mod loader references in my code.

Actually I don't, I thought I made one. Would that be whats messing this all up on me?

Or am I doing something entirely different?

I figured out the GuiHandler and everything to get a block gui working, but I can't figure out the procedure for the handler for an item.

I have that much so far in the item class, I'm just clueless to the structure/methods I need to use in the guihandler (client / server functions like for tile entity and container )

Right, but now if its an item and I don't plan on it having a container, wouldn't I just need the GUI class and the handler? I'm sorry I'm new and completely lost trying to get this to work

How would I go about doing that? I'm sorry I just don't see ANY tutorials whatsoever for making GUI's for items in forge. The best I found was modloader and I would prefer not using modloader. I'm trying to basically have it like in thaumcraft where you will open a book and it will have instructions/recipes to the things the player will be doing, as well as the book being used in a receptacle and when the book is in the receptacle you will have a new gui extending from the block that will act as a container/tile entity. I'm not sure if what I am trying to do with the book requires it to be a tile entity or a container, and what code is required to set it up in the guiscreen/proxy/item class or where to find references on how to do it. I have it working perfectly with the block acting as a container and it has its gui but this has me completely stumped.

Awesome then, Thank you so much for the help. It will have to be server side, odds are I will have more questions but I will try to figure this out. Again thank you so much
