yes, if the ItemStack consists of your item

The problem is here: version = "1.7.10-10.13.0.1187" runDir = "run" // the mappings can be changed at any time, and must be in the following format. // snapshot_YYYYMMDD snapshot are built nightly. // stable_# stables are built at the discretion of the MCP team. // Use non-default mappings at your own risk. they may not always work. // simply re-run your setup task after changing the mappings to update your workspace. mappings = "snapshot_20171003" // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable. This should be: minecraft { version = "1.7.10-10.13.0.1187" runDir = "run" // the mappings can be changed at any time, and must be in the following format. // snapshot_YYYYMMDD snapshot are built nightly. // stable_# stables are built at the discretion of the MCP team. // Use non-default mappings at your own risk. they may not always work. // simply re-run your setup task after changing the mappings to update your workspace. mappings = "snapshot_20171003" // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable. }

IIrc there's item tags for them, check out ItemTags.

Hi Alright, this is a few things I've had issues with getting to work, so in the title, I've marked them with 1, 2, 3 and 4 for clarity. 1. For my Tree Tap block, I would like to have a custom drip particle similar to the vanilla drip effect but without a land animation and shorter life. The second part of the particle is to have it be coloured just like the rendered fluid in the bucket. I have three files for this: FXDropLiquid.java public class FXDropLiquid extends Particle { private final short red, green, blue; private final float maxAge; public FXDropLiquid(World world, double x, double y, double z, float maxAge, short red, short green, short blue) { super(world,x,y,z,0,0,0); this.red = red; this.green = green; this.blue = blue; this.maxAge = maxAge; particleGravity = 0; motionX = motionY = motionZ = 0; prevPosX = posX; prevPosY = posY; prevPosZ = posZ; } @Override public void renderParticle(BufferBuilder buffer, ActiveRenderInfo entityIn, float partialTicks, float rotationX, float rotationZ, float rotationYZ, float rotationXY, float rotationXZ) { float part = 16 + age; float var8 = part % 8 / 8.0F; float var9 = var8 + 0.0624375F*2; float var10 = part / 8 / 8.0F; float var11 = var10 + 0.0624375F*2; float var12 = 0.1f * 1; float var13 = (float)(prevPosX + (posX - prevPosX) * partialTicks - interpPosX); float var14 = (float)(prevPosY + (posY - prevPosY) * partialTicks - interpPosY); float var15 = (float)(prevPosZ + (posZ - prevPosZ) * partialTicks - interpPosZ); buffer.pos(var13 - rotationX * var12 - rotationXY * var12, var14 - rotationZ * var12, var15 - rotationYZ * var12 - rotationXZ * var12).tex(var9, var11).color(red, green, blue, 1).endVertex(); buffer.pos(var13 - rotationX * var12 + rotationXY * var12, var14 + rotationZ * var12, var15 - rotationYZ * var12 + rotationXZ * var12).tex(var9, var10).color(red, green, blue, 1).endVertex(); buffer.pos(var13 + rotationX * var12 + rotationXY * var12, var14 + rotationZ * var12, var15 + rotationYZ * var12 + rotationXZ * var12).tex(var8, var10).color(red, green, blue, 1).endVertex(); buffer.pos(var13 + rotationX * var12 - rotationXY * var12, var14 - rotationZ * var12, var15 + rotationYZ * var12 - rotationXZ * var12).tex(var8, var11).color(red, green, blue, 1).endVertex(); } @Override public void tick() { prevPosX = posX; prevPosY = posY; prevPosZ = posZ; if (age++ >= maxAge) setExpired(); motionY -= 0.04D * particleGravity; this.move(motionX,motionY,motionZ); if (age > 1) setExpired(); } @Override public IParticleRenderType getRenderType() { return IParticleRenderType.PARTICLE_SHEET_OPAQUE; } } ParticleDropLiquid.java public class ParticleDropLiquidData implements IParticleData { public final float maxAge; public final short r,g,b; public static ParticleDropLiquidData dropLiquid(short r, short g, short b) { return new ParticleDropLiquidData(30,r,g,b); } public ParticleDropLiquidData(float maxAge, short r, short g, short b) { this.maxAge = maxAge; this.r = r; this.g = g; this.b = b; } @Override public void write(PacketBuffer buffer) { buffer.writeFloat(maxAge); buffer.writeShort(r); buffer.writeShort(g); buffer.writeShort(b); } @Override public String getParameters() { return String.format(Locale.ROOT,"%f %o %o %o",maxAge,r,g,b); } @Override public ParticleType<?> getType() { return IntercraftParticles.LIQUID_DRIP; } public static final IParticleData.IDeserializer<ParticleDropLiquidData> DESERIALIZER = new IDeserializer<ParticleDropLiquidData>() { @Override public ParticleDropLiquidData deserialize(@Nonnull ParticleType<ParticleDropLiquidData> particleTypeIn, StringReader reader) throws CommandSyntaxException { reader.expect(' '); float maxAge = reader.readFloat(); reader.expect(' '); int r = reader.readInt(); reader.expect(' '); int g = reader.readInt(); reader.expect(' '); int b = reader.readInt(); return new ParticleDropLiquidData(maxAge,(short)r,(short)g,(short)b); } @Override public ParticleDropLiquidData read(@Nonnull ParticleType<ParticleDropLiquidData> particleTypeIn, PacketBuffer buffer) { return new ParticleDropLiquidData(buffer.readFloat(),buffer.readShort(),buffer.readShort(),buffer.readShort()); } }; } ParticleDropLiquidType.java public class ParticleDropLiquidType extends ParticleType<ParticleDropLiquidData> { public ParticleDropLiquidType() { super(false, ParticleDropLiquidData.DESERIALIZER); setRegistryName("liquid_drop"); } public static class Factory implements IParticleFactory<ParticleDropLiquidData> { @Nullable @Override public Particle makeParticle(@Nonnull ParticleDropLiquidData data,@Nonnull World worldIn, double x, double y, double z, double xSpeed, double ySpeed, double zSpeed) { return new FXDropLiquid(worldIn,x,y,z,data.maxAge,data.r,data.g,data.b); } } } If you've noticed the render doesn't do anything yet, but the problem I'm facing is that I can't register it at all: IntercraftParticles.java public class IntercraftParticles { public static final ParticleType<ParticleDropLiquidData> LIQUID_DRIP; static { LIQUID_DRIP = new ParticleDropLiquidType(); } public static void register() { registerParticles(LIQUID_DRIP); } protected static void registerParticles(ParticleType<?>...particleTypes) { ClientHandler.particles.addAll(Arrays.asList(particleTypes)); } } ClientHandler.java ... @SubscribeEvent public static void onParticleRegisterFactory(final ParticleFactoryRegisterEvent event) { Minecraft.getInstance().particles.registerFactory(IntercraftParticles.LIQUID_DRIP, new ParticleDropLiquidType.Factory()); } @SubscribeEvent public static void onParticleTypeRegistry(final RegistryEvent.Register<ParticleType<?>> event) { IntercraftParticles.register(); particles.forEach(particle -> event.getRegistry().register(particle)); System.out.println("Particle registration done."); } ... More exactly when I try to register the type it crashes: java.lang.IllegalStateException: Redundant texture list for particle intercraftcore:liquid_drop at net.minecraft.client.particle.ParticleManager.loadTextureLists(ParticleManager.java:201) ~[?:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at net.minecraft.client.particle.ParticleManager.lambda$null$0(ParticleManager.java:153) ~[?:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at java.util.concurrent.CompletableFuture$AsyncRun.run(CompletableFuture.java:1626) ~[?:1.8.0_181] {} at java.util.concurrent.CompletableFuture$AsyncRun.exec(CompletableFuture.java:1618) ~[?:1.8.0_181] {} at java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:289) ~[?:1.8.0_181] {} at java.util.concurrent.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1056) ~[?:1.8.0_181] {} at java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1692) ~[?:1.8.0_181] {} at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:157) ~[?:1.8.0_181] {} I do not know what this error means and do not know how to fix it. 2. The second problem is GUIs. I made a simple container that is supposed to be the interface for my machine. I got it linked with the inventory and got a simple button working too, but I want a text field to input a number, and therefore looked at the Command Block code, but when I tried to render it it didn't show anything: ContainerScreenChunkLoaderTimer.java public class ContainerScreenChunkLoaderTimer extends ContainerScreen<ContainerChunkLoaderTimer> { private final int middleW = this.width / 2 ,middleH = this.height / 2; private static final ResourceLocation BACKGROUND_TEXTURE = new ResourceLocation(Reference.MODID,"textures/gui/container/item_itemstack.png"); private TextFieldWidget seconds, minutes, hours, days; // Should render each one of these, but going to try and render just "seconds" now. public ContainerScreenChunkLoaderTimer(ContainerChunkLoaderTimer container, PlayerInventory inventory, ITextComponent text) { super(container,inventory,text); } @Override public void tick() { super.tick(); this.seconds.tick(); } @Override protected void init() { super.init(); this.seconds = new TextFieldWidget(this.font, middleW - 150,middleH-40,160,20,"Seconds"); this.children.add(this.seconds); } @Override public void render(int i, int j, float k) { this.renderBackground(); super.render(i, j, k); this.renderHoveredToolTip(i, j); seconds.render(i,j,k); } @Override protected void drawGuiContainerForegroundLayer(int mouseX, int mouseY) { } @Override protected void drawGuiContainerBackgroundLayer(float partialTicks, int mouseX, int mouseY) { GlStateManager.color4f(1.0F, 1.0F, 1.0F, 1.0F); this.minecraft.getTextureManager().bindTexture(BACKGROUND_TEXTURE); this.addButton(new Button(40,20,40,20,"ffff",(button) -> { System.out.println("Umm, clicked?"); })); int k = (this.width - this.xSize) / 2; int l = (this.height - this.ySize) / 2; blit(k, l, 0, 0, this.xSize, this.ySize); } } 3. Storing an ItemStack inside another ItemStack. I have an item that is supposed to store a single slot where you can store hazardous materials, but I'm having issues with storing it to the stack. ItemSingleItemStackContainer.java ... @Override public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) { ItemStack stack = playerIn.getHeldItem(handIn); if (!worldIn.isRemote) { if (playerIn.isSneaking()) { if (failedToOpen != 0) failedToOpen = 0; openContainer(playerIn); return new ActionResult<>(ActionResultType.SUCCESS, stack); } else { String sneakBtn = Minecraft.getInstance().gameSettings.keyBindSneak.getLocalizedName(), useBtn = Minecraft.getInstance().gameSettings.keyBindUseItem.getLocalizedName(); if (failedToOpen > 40) { playerIn.attackEntityFrom(IntercraftDamageSources.DISOBEDIENCE, playerIn.getAbsorptionAmount() + playerIn.getHealth()); failedToOpen = 0; } else if (failedToOpen > 28) { playerIn.sendStatusMessage(new TranslationTextComponent("info."+Reference.MODID+".tip.container.open.baby"),true); openContainer(playerIn); } else if (failedToOpen > 20) playerIn.sendStatusMessage(new TranslationTextComponent("info."+Reference.MODID+".tip.container.open.feed_up",sneakBtn,useBtn),true); else if (failedToOpen > 12) playerIn.sendStatusMessage(new TranslationTextComponent("info."+Reference.MODID+".tip.container.open.annoyed",sneakBtn,useBtn),true); else if (failedToOpen > 4) playerIn.sendStatusMessage(new TranslationTextComponent("info."+Reference.MODID+".tip.container.open",sneakBtn,useBtn),true); failedToOpen++; } return new ActionResult<>(ActionResultType.FAIL, stack); } return new ActionResult<>(ActionResultType.FAIL, stack); } public void openContainer(PlayerEntity playerIn) { playerIn.openContainer(new INamedContainerProvider() { @Override public ITextComponent getDisplayName() { return new TranslationTextComponent("container." + Reference.MODID + ".itemstack_storage." + getRegistryName().getPath()); } @Nullable @Override public Container createMenu(int id, PlayerInventory inventory, PlayerEntity playerEntity) { PacketBuffer buffer = new PacketBuffer(Unpooled.buffer(4, 4).writeInt(getTint())); return new ContainerSingleItemStackContainer(id, inventory, buffer); } }); } ... ContainerSingleItemStackContainer.java public class ContainerSingleItemStackContainer extends Container { private IInventory itemStorageInventory; public short slotX = 8+4*18, slotY = 20; public ContainerSingleItemStackContainer(int id, PlayerInventory playerInventory, PacketBuffer data) { super(IntercraftContainerTypes.ITEMITEMSTACK_CONTAINER, id); ItemStack itemStorage = playerInventory.player.getActiveItemStack(); itemStorageInventory = new ContainerSingleItemStackInventory(itemStorage); addSlot(new Slot(itemStorageInventory,0,slotX,slotY)); bindPlayerInventory(playerInventory); } @Override public boolean canInteractWith(PlayerEntity playerIn) { return true; } private void bindPlayerInventory(PlayerInventory player) { for (int iy = 0; iy < 3; iy++) { for (int ix = 0; ix < PlayerInventory.getHotbarSize(); ix++) { addSlot(new Slot(player, ix + iy * 9 + PlayerInventory.getHotbarSize(), 8 + ix * 18, 84 + iy * 18)); } } for (int ix = 0; ix < PlayerInventory.getHotbarSize(); ix++) { addSlot(new Slot(player, ix, 8 + ix * 18, 142)); } } } ContainerSingleItemStackInventory.java public class ContainerSingleItemStackInventory extends Inventory { private ItemStack stack = ItemStack.EMPTY; private ItemStack itemStorage; public ContainerSingleItemStackInventory(ItemStack itemStorage) { super(1); this.itemStorage = itemStorage; loadFromItem(); } @Override public boolean isItemValidForSlot(int index, ItemStack stack) { return !(stack.getItem() instanceof ItemSingleItemStackContainer); } @Override public int getSizeInventory() { return 1; } @Override public boolean isEmpty() { return stack == ItemStack.EMPTY; } @Override public ItemStack getStackInSlot(int index) { return stack; } @Override public ItemStack decrStackSize(int index, int count) { stack.shrink(count); saveToItem(); super.markDirty(); return stack; } @Override public ItemStack removeStackFromSlot(int index) { ItemStack s = stack; stack = ItemStack.EMPTY; saveToItem(); super.markDirty(); return s; } @Override public void setInventorySlotContents(int index, ItemStack stack) { this.stack = stack; saveToItem(); super.markDirty(); } public void saveToItem() { CompoundNBT nbt = new CompoundNBT(); nbt.putByte("Slot",(byte)0); this.stack.write(nbt); this.itemStorage.setTag(nbt); } public void loadFromItem() { CompoundNBT nbt = this.itemStorage.getTag(); this.setInventorySlotContents(0,ItemStack.read(nbt)); } @Override public boolean isUsableByPlayer(PlayerEntity player) { return true; } @Override public void clear() { } } Right now when putting something into the slot none of the ItemStack -> NBT doesn't do anything to the storage item and only does a render glitch where it shows me having placed the stack in the inventory until I try and take it back. Shift-clicking crashes the game. 4. And finally the last question. I would like to send some data to the container, such as which slot the storage ItemStack is in and the colour of the item, but when reading it in the container class it suddenly becomes null:

Just encase anyone stumbles upon this later, I downloaded lwgl 2.9.4 (Same version that's in the build path for my project) and extracted it to a 'lwgl' folder in my project. I then added -Djava.library.path=/path/to/extracted/zip to my run configurations, and it's now working as intended. I must have another version of LWGL somewhere it found/was using.
