Problem Creating a Gui Handler

clowcadia · February 16, 2017

So I am following another outdated tutorial, so as usual there is an issue

package com.clowcadia.mod;

import net.minecraftforge.fml.common.network.IGuiHandler;

public class ModGuiHandler implements IGuiHandler {

    @Override
    public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
        return null;
    }

    @Override
    public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
        return null;
    }
}

Edit: Sorry, I replied too late.

Neither one of the suggestions are (technically) correct. In this case, "implement methods" would work but it may cause a problem (duplicate method signatures) when there's an easier solution (importing the right classes).

Alright I did some updating and error checking, but still no go.

Main:

package com.clowcadia.mod;

import com.clowcadia.mob.Blank;
import com.clowcadia.mod.CEventHandler;

import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.Mod.Instance;
import net.minecraftforge.fml.common.Mod.Metadata;
import net.minecraftforge.fml.common.ModMetadata;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import net.minecraftforge.fml.common.network.NetworkRegistry;
import net.minecraftforge.fml.common.registry.EntityRegistry;


@Mod(modid = ClowcadiaMod.MODID, version = ClowcadiaMod.VERSION)
public class ClowcadiaMod
{
    public static final String MODID = "clowcadiamod";
    public static final String VERSION = "1.0";
    CEventHandler events = new CEventHandler();
    
    @Metadata
    public static ModMetadata meta;
    
    @Instance
    public static ClowcadiaMod modInstance;
    
    @EventHandler
    public void PreLoad(FMLPreInitializationEvent PreEvent)
    {
    	mainRegistry();
    	
    }
    
    @EventHandler
    public void load(FMLInitializationEvent event)
    {
    	NetworkRegistry.INSTANCE.registerGuiHandler(modInstance, new GuiHandler());
    	
    }
    
    @EventHandler
    public void PostLoad(FMLPostInitializationEvent PostEvent)
    {
    	
    }
    
    public static void mainRegistry()
	{
		EntityRegistry.registerModEntity(new ResourceLocation(ClowcadiaMod.MODID,"blankMob"), Blank.class, "blankMob", 
				0, ClowcadiaMod.modInstance, 64, 1, true, 0x4286f4, 0x606e84);;
	}
}

GuiHandler

package com.clowcadia.mod;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.network.IGuiHandler;

public class GuiHandler implements IGuiHandler {

	public static final int GUI = 0;
	
	public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z)
	{
		return null;
	}
	
	@Override
	public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z)
	{
		if (ID == GUI)
	        return new Gui();
	    return null;
		
	}
}

Gui

package com.clowcadia.mod;

import net.minecraft.client.gui.GuiScreen;

public class Gui extends GuiScreen 
{
	@Override
	public void drawScreen(int mouseX, int mouseY, float partialTicks) 
	{
		this.drawDefaultBackground();
	    super.drawScreen(mouseX, mouseY, partialTicks);
	}
	
	
}

Blank

package com.clowcadia.mob;

import com.clowcadia.mod.ClowcadiaMod;

import net.minecraft.entity.monster.EntityMob;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.EnumHand;
import net.minecraft.world.World;

public class Blank extends EntityMob{

	public Blank(World worldIn) {
		super(worldIn);
		// TODO Auto-generated constructor stub
	}
	public boolean processInteract(EntityPlayer player, EnumHand hand)
    {
		if (!this.world.isRemote)
		{
			System.out.println("Player has interacted with the mob");
			player.openGui(ClowcadiaMod.modInstance, 0, this.world, (int) player.posX, (int) player.posY, (int) player.posZ);
			
		}
		return true;
    }
	
	

}

Lol made a quick edit where i added World world. and it all crashed

package com.clowcadia.mob;

import com.clowcadia.mod.ClowcadiaMod;

import net.minecraft.entity.monster.EntityMob;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.EnumHand;
import net.minecraft.world.World;

public class Blank extends EntityMob{

	World world;
	
	public Blank(World worldIn) {
		super(worldIn);
		// TODO Auto-generated constructor stub
	}
	public boolean processInteract(EntityPlayer player, EnumHand hand)
    {
		if (!this.world.isRemote)
		{
			System.out.println("Player has interacted with the mob");
			player.openGui(ClowcadiaMod.modInstance, 0, world, (int) player.posX, (int) player.posY, (int) player.posZ);
			
		}
		return true;
    }
	
	

}

java.lang.NullPointerException

at com.clowcadia.mob.Blank.processInteract(Blank.java:20) ~[Blank.class:?]

world is null because you never assign anything to it:

World world;

You shouldn't even have this field as Entity already has a world object field, it's (unsurprisingly) called worldObj
.

Ok what about my post before the crash

Is this method of calling a gui even posible?

Draco18s · February 17, 2017

Yes. You're just doing it wrong.

clowcadia · February 17, 2017

ok thank you, by the int s is because i am getting returned double, so casting them into integer. by the way how can i do it right?

clowcadia · February 17, 2017

getClientGuiElement returns Gui class, that doess have a method for gui screen , whats wrong with that

clowcadia · February 17, 2017

import net.minecraft.world.World;

public class GuiHandler implements IGuiHandler {

	public static final int GUI = 0;
	
	@Override
	public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z)
	{
		if (ID == GUI)
