[Warix]

So i tried to do what title says, and i get error for null exception, i tried to set nbt from this.mc.thePlayer.getItemInUse();

my code:

 

package ga.warixmods.mymodmod.inventory;

 

import java.io.IOException;

 

import org.lwjgl.input.Keyboard;

 

import ga.warixmods.mymodmod.client.gui.GuiWandButton1;

import ga.warixmods.mymodmod.client.gui.GuiWandButton2;

import ga.warixmods.mymodmod.client.gui.GuiWandButton3;

import ga.warixmods.mymodmod.client.gui.GuiWandButton4;

import ga.warixmods.mymodmod.init.mod1Items;

import net.minecraft.client.Minecraft;

import net.minecraft.client.gui.FontRenderer;

import net.minecraft.client.gui.GuiButton;

import net.minecraft.client.gui.GuiLabel;

import net.minecraft.client.gui.GuiScreen;

import net.minecraft.client.gui.GuiTextField;

import net.minecraft.client.renderer.GlStateManager;

import net.minecraft.client.renderer.Tessellator;

import net.minecraft.client.renderer.WorldRenderer;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.entity.player.InventoryPlayer;

import net.minecraft.init.Blocks;

import net.minecraft.inventory.Container;

import net.minecraft.inventory.ContainerRepair;

import net.minecraft.item.ItemStack;

import net.minecraft.nbt.NBTTagCompound;

import net.minecraft.util.BlockPos;

import net.minecraft.util.ChatComponentTranslation;

import net.minecraft.util.IChatComponent;

import net.minecraft.util.ResourceLocation;

import net.minecraft.world.IInteractionObject;

import net.minecraft.world.World;

 

public class GuiWand extends GuiScreen{

public static final int GUI_ID = 20;

public ItemStack stack = mc.thePlayer.getItemInUse();

public GuiWand () {}

    @Override

    public void initGui()

    {

    buttonList.add(new GuiWandButton1(0, width / 2 - 100 , height / 2 - 20,"1"));

    buttonList.add(new GuiWandButton2(1, width / 2 - 50, height / 2 - 20,"1"));

    buttonList.add(new GuiWandButton3(2, width / 2 + 0, height / 2 - 20,"1"));

    buttonList.add(new GuiWandButton4(3, width / 2  + 50, height / 2 - 20,"1"));

    }

    protected static final ResourceLocation buttonTextures1 = new ResourceLocation("agkm:textures/gui/demo_background.png");

@Override

    public void drawScreen(int mouseX, int mouseY, float partialTicks)

    {

this.drawDefaultBackground();

        mc.getTextureManager().bindTexture(buttonTextures1);

        this.drawTexturedModalRect(width / 2 - 125, height / 2 - 75,0,0, 247, 125);

        this.fontRendererObj.drawString("Choose the power you want to use:", width / 2- 100, height / 2  - 50, 1);

        super.drawScreen(mouseX, mouseY, partialTicks);

        mc.thePlayer.setCurrentItemOrArmor(4, new ItemStack(mod1Items.murasame,1));

       

       

    }

    @Override

    public void actionPerformed(GuiButton button) throws IOException

    {

    NBTTagCompound nbt = new NBTTagCompound();

    switch(button.id)

    {

    case 0: 

    if(!stack.getTagCompound().hasKey("power"))

    {

        nbt.setInteger("id", 0);

        stack.getTagCompound().setTag("power", nbt);

    }

    this.mc.displayGuiScreen((GuiScreen)null);

    this.mc.setIngameFocus();

    break;

    case 1:

    if(!stack.getTagCompound().hasKey("power"))

    {

        nbt.setInteger("id", 1);

        stack.getTagCompound().setTag("power", nbt);

    }

    this.mc.displayGuiScreen((GuiScreen)null);

    this.mc.setIngameFocus();

    break;

    case 2:

    if(!stack.getTagCompound().hasKey("power"))

    {

        nbt.setInteger("id", 2);

        stack.getTagCompound().setTag("power", nbt);

    }

    this.mc.displayGuiScreen((GuiScreen)null);

    this.mc.setIngameFocus();

    break;

    case 3:

    if(!stack.getTagCompound().hasKey("power"))

    {

        nbt.setInteger("id", 3);

        stack.getTagCompound().setTag("power", nbt);

    }

    this.mc.displayGuiScreen((GuiScreen)null);

    this.mc.setIngameFocus();

    break;

   

   

   

    }

    this.updateScreen();

    }

 

 

 

 

 

 

}

 

 

Basically i want to make item, when you right click with him it uses power depending on nbt tag, and when u shift right click you choose which power you want to use from custom gui. If there is better solution for this please tell me. and also there is error :

I get error when i try to shift right click with that item.

[coolAlias]

1. EntityPlayer#getItemInUse can be null, and always will be in your case (can't be using an item while in a GUI)

2. ItemStack#getTagCompound can be null

3. You can NOT set NBT data on the client - you must send a packet to the server

[Warix]

Thanks, i know they can be null but they won't since they are only called when i use that item with shift right click i guess. Or am I using wrong function to get item in hand? i tried with .getHeldItem() but it gives same error, i will try to do packets.

[Failender]

They still might be able to change their item for whatever reason, so better insert a little check instead of crashing minecraft :b

Track down what is causing the exception, and add null checks if u use things that can be null while using

[Warix]

- What does the "mc" thing point to in that code? It is not resolved from the code you pasted. It may be null.

- Are you sure the client player already exists when you open the GUI? Otherwise Minecraft#thePlayer will be null.

It's pointing to GuiScreen class

I did check now and it seems that mc is null. I don't have other ideas how to access players inventory so i guess only solution left is to do packets?

[Failender]

you are opening your gui via your gia handler. the handler gives you an entityplayer object that you can pass using the constructor of ur gui

[Warix]

Thanks, I didn't know about this.
