Follow the line 189 in "my_item" file:

 

 

  Reveal hidden contents

 

FMLCommonHandler.instance().showGuiScreen(new myGuiHandler().getClientGuiElement(1, par3EntityPlayer, par2World, (int)par3EntityPlayer.posX, (int)par3EntityPlayer.posY, (int)par3EntityPlayer.posZ));

 

 

 

 

 

And this is the code of "myGuiHandler" file:

 

 

  Reveal hidden contents

 

package mymod;

 

import cpw.mods.fml.common.network.IGuiHandler;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.world.World;

 

public class myGuiHandler implements IGuiHandler

{

  @Override

    public Object getServerGuiElement(int var1, EntityPlayer var2, World var3, int var4, int var5, int var6)

    {

        return null;

    }

  @Override

    public Object getClientGuiElement(int var1, EntityPlayer var2, World var3, int var4, int var5, int var6)

    {

        return var2.getCurrentEquippedItem() != null && var2.getCurrentEquippedItem().getItem() instanceof my_item ? new myGui(var2) : null;

    }

}

 

 

 

 

The "myGui" file is a normal GUIScreen class object.

 

 

Please i need HELP!!!

 

-----------

 

Solution (thanks to diesieben07 and opssemnik):

 

just using EntityPlayer.opengui(mod obj, gui id, x,y,z) function

 

Thanks

[opssemnik]

the right way to open a gui its EntityPlayer.opengui(mod obj, gui id, x,y,z) //u need a entity player obj

[zedblade]

Ok,

 

thank you for reply.

 

I've replace the line 189 with this:

 

par3EntityPlayer.openGui(mymod.instance, 1, par2World, (int)par3EntityPlayer.posX, (int)par3EntityPlayer.posY, (int)par3EntityPlayer.posZ);

 

But when i try to open the gui:

 

"A mod tried to open a gui on the server without being a NetworkMod"

 

my mod has 3 different gui classes but i dont know how to declare or refer the IDs

 

Into main class file it's declared this:

 

@NetworkMod(

clientSideRequired = true,

serverSideRequired = false,

channels = {"MyMod"},

packetHandler = ServerPacketHandler.class

)

 

Any suggestion?

Some(great)body can help me?

What about your proxy classes?

Do you have commonProxy and clientProxy?

I'm going to assume that you're server is calling a client only method, that's why it is crashing!

The server should never handle client side things

 

Take a look at:

http://www.minecraftforge.net/wiki/Basic_Modding

It will help you setup the CommonProxy and ClientProxy files correctly.

While http://www.minecraftforge.net/wiki/Containers_and_GUIs may give you some more help inn calling the GUI and such.

[zedblade]

Yes, i've both ClientProxy and CommonProxy. I literally followed any mod guide line.

 

And my 3 GUI aren't container GUI.

 

But the error still happen.

 

There must be something wrong into the @NetworkMod declaration.

 

This my main mod class code:

package MyMod;

 

import net.minecraft.block.Block;

import net.minecraft.item.ItemStack;

import net.minecraft.item.Item;

 

import net.minecraftforge.common.Configuration;

import cpw.mods.fml.common.network.NetworkMod;

import cpw.mods.fml.common.network.NetworkMod.SidedPacketHandler;

import cpw.mods.fml.common.network.NetworkRegistry;

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

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

 

@Mod(modid = "MyMod", name = "MyMod", version = "xxx")

 

@NetworkMod(

clientSideRequired = true,

serverSideRequired = false,

channels = {"MyMod"},

packetHandler = ServerPacketHandler.class

)

 

public class MyMod

{

    @Instance("MyMod")

    public static MyMod instance;

    public static GuiHandler guiHandler = new GuiHandler();

   

    @SidedProxy(

            clientSide = "MyMod.ClientProxy",

            serverSide = "MyMod.CommonProxy"

    )

   

    public static CommonProxy proxy;

   

    @PreInit

    public void preInit(FMLPreInitializationEvent var1)

    {

        //My config file

    }

 

    @Init

    public void load(FMLInitializationEvent event)

    {

    proxy.registerRenderers();

       

        //Registering GuiHandler

        NetworkRegistry.instance().registerGuiHandler(this, new GuiHandler());

       

        //declaring object

 

        //Registering Block

       

        //Adding ItemName

       

        // RECIPIES

 

    }

}

 

 

 

Proxies:

COMMONPROXY:

package MyMod

 

public class CommonProxy

{

    public static String ITEMS = "/gui/images.png";

 

    public void registerRenderers() {}

}

 

CLIENTPROXY:

package MyMod;

 

import net.minecraftforge.client.MinecraftForgeClient;

 

public class ClientProxy extends CommonProxy

{

    public void registerRenderers()

    {

    ITEMS = "/gui/images.png";

        MinecraftForgeClient.preloadTexture(ITEMS);

    }

}

 

 

 

And This is GuiHandler code:

package MyMod;

            return new Gui1(var2);

 

            case 1:

            return new Gui2(var2);

 

            case 2:

            return new Gui3(var2);

 

        }

       

        return null;

    }

@Override

    public Object getClientGuiElement(int var1, EntityPlayer var2, World var3, int var4, int var5, int var6)

    {

        switch (var1)

        {

            case 0:

            return new Gui1(var2);

 

            case 1:

            return new Gui2(var2);

 

            case 2:

            return new Gui3(var2);

 

        }

       

        return null;

    }

}
