It works. And thanks for the tips.

If it helps here is the class of the ItemTest: public class ItemTest extends Item { public static ItemTest create() { ItemTest result = new ItemTest (); result.init(); return result; } protected ItemTest () { setCreativeTab(EnderIOTab.tabEnderIO); setUnlocalizedName("itemTest"); setMaxDamage(0); setMaxStackSize(1); } @Override public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player) { if (itemStack.stackTagCompound==null){ itemStack.stackTagCompound = new NBTTagCompound(); itemStack.stackTagCompound.setString("text", ""); } if (!world.isRemote){ Minecraft.getMinecraft().displayGuiScreen(new TestGui(itemStack)); } return itemStack; } @Override public void onCreated(ItemStack itemStack, World world, EntityPlayer entityPlayer) { if (itemStack.stackTagCompound==null){ itemStack.stackTagCompound = new NBTTagCompound(); itemStack.stackTagCompound.setString("text", ""); } super.onCreated(itemStack, world, entityPlayer); } @Override public void addInformation(ItemStack itemStack, EntityPlayer entityPlayer, List list, boolean b) { if (itemStack.stackTagCompound==null){ itemStack.stackTagCompound = new NBTTagCompound(); itemStack.stackTagCompound.setString("text", ""); } list.add(itemStack.stackTagCompound.getString("text")); } @Override @SideOnly(Side.CLIENT) public void registerIcons(IIconRegister IIconRegister) { itemIcon = IIconRegister.registerIcon("enderiofilters:itemTest"); } private void init() { GameRegistry.registerItem(this, "itemTest"); } }

But how do i get the ItemStack on the server?

public class PacketTestItem implements IMessageHandler<PacketTestItem, IMessage>, IMessage { private ItemStack itemTest; private String text; public PacketTestItem () { } public PacketTestItem (ItemStack itemTest, String text) { this.itemTest= itemTest; this.text= text; } @Override public void fromBytes(ByteBuf buf) { itemTest= ByteBufUtils.readItemStack(buf); text= ByteBufUtils.readUTF8String(buf); } @Override public void toBytes(ByteBuf buf) { ByteBufUtils.writeItemStack(buf, itemTest); ByteBufUtils.writeUTF8String(buf, text); } @Override public IMessage onMessage(PacketTestItem message, MessageContext ctx) { message.itemTest.stackTagCompound.setString("text",message.text); return null; } }

Hey everyone! I have a problem with setting the nbt data of an item inside a gui. I am able to set the nbt data of the item in the Constructor and in the initGui() method, but when i try to set it in the onGuiClosed() method the nbt data isn't changed. Can someone explain why and how i can fix it? Here the code of the onGuiClosed method: @Override public void onGuiClosed() { super.onGuiClosed(); String s = textField.getText(); itemTest.stackTagCompound.setString("text", s); System.out.println(itemTest.stackTagCompound.getString("text")); //here it shows the right value PacketHandler.INSTANCE.sendToServer(new PacketTestItem(itemTest, s)); }

Thanks, i will try that!

I thought about that. But when i change it like that, there aren't any changes made to the server, so it doesn't work

So how can I fix this?

in this function @Override public boolean onItemUse(ItemStack item, EntityPlayer player, World world, int x, int y, int z, int par7, float xFloat, float yFloat, float zFloat) { if (!player.canPlayerEdit(x, y, z, par7, item)){ return false; } if (!world.isRemote){ Block target = world.getBlock(x, y, z); Minecraft.getMinecraft().displayGuiScreen(new TestBlockGui(target,world,x,y,z)); } return true;

In line 71 there is only drawDefaultBackground(); rest of the class: package com.guje.test_mod; import org.lwjgl.opengl.GL11; import net.minecraft.block.Block; import net.minecraft.client.gui.GuiButton; import net.minecraft.client.gui.GuiScreen; import net.minecraft.client.gui.GuiTextField; import net.minecraft.util.ResourceLocation; import net.minecraft.world.World; public class TestBlockGui extends GuiScreen { private int textureX; private int textureY; private int posY; private int posX; private int bY; private int bX; private int bZ; private ResourceLocation texture; private World world; private String blockId; private String blockMetadata; private GuiTextField text_BlockId; private GuiTextField text_BlockMetadata; public TestBlockGui(Block block, World world, int bX, int bY, int bZ) { super(); this.textureX = 175; this.textureY = 221; this.bX = bX; this.bY = bY; this.bZ = bZ; this.world = world; this.blockId = block.getIdFromBlock(block)+""; this.blockMetadata = world.getBlockMetadata(bX, bY, bZ)+""; texture = new ResourceLocation(Hack_n_Mine.MODID, "textures/gui/hackingGui.png"); } @Override public void initGui() { buttonList.clear(); posX = (this.width - textureX) / 2; posY = (this.height - textureY) / 2; text_BlockId = new GuiTextField(fontRendererObj, posX + 77, posY + 5, 40, 10); text_BlockId.setText(blockId); text_BlockId.setMaxStringLength(5); text_BlockMetadata = new GuiTextField(fontRendererObj, posX + 77, posY + 18, 40, 10); text_BlockMetadata.setText(blockMetadata); text_BlockMetadata.setMaxStringLength(5); super.initGui(); } @Override protected void keyTyped(char c, int i) { text_BlockId.textboxKeyTyped(c, i); text_BlockMetadata.textboxKeyTyped(c, i); super.keyTyped(c, i); } @Override protected void mouseClicked(int i, int j, int f) { text_BlockId.mouseClicked(i, j, f); text_BlockMetadata.mouseClicked(i, j, f); super.mouseClicked(i, j, f); } @Override public void drawScreen(int x, int y, float f) { drawDefaultBackground(); GL11.glColor4f(1F,1F,1F,1F); posX = (this.width - textureX) / 2; posY = (this.height - textureY) / 2; mc.renderEngine.bindTexture(texture); drawTexturedModalRect(posX, posY, 0, 0, textureX, textureY); text_BlockId.drawTextBox(); text_BlockMetadata.drawTextBox(); fontRendererObj.drawString("BlockID", posX + 5, posY + 7, 0x404040); fontRendererObj.drawString("BlockMetadata", posX + 5, posY + 19, 0x404040); super.drawScreen(x, y, f); } @Override public void onGuiClosed() { //Set blockId and metadata Block b = Block.getBlockById(Integer.parseInt(text_BlockId.getText())); int m = Integer.parseInt(text_BlockMetadata.getText()); world.setBlock(bX, bY, bZ, b, m, 3); super.onGuiClosed(); } }

Sometimes, when I open my customGui, the server shuts down and shows this error: Stacktrace: at net.minecraft.client.gui.GuiScreen.drawWorldBackground(GuiScreen.java:396) at net.minecraft.client.gui.GuiScreen.drawDefaultBackground(GuiScreen.java:391) at com.guje.test_mod.TestBlockGui.drawScreen(TestBlockGui.java:71)

I tried the fix, but it caused my mod to be loaded twice, so i wasn't able to start minecraft. I will just take the easy way and switch to eclipse. Thanks never the less

Hello, I have problems adding custom textures to an item. I have the feeling there is a problem copying the assets, because the item also has the wrong name in game.
