No I changed this. In the method addSlot I changed the player inv to the tileentity inv but now there is a nullpointer exception. It seems like that the inventory is null but: public InventoryBasic inv; private static int ID = 0; public TileEntityChemicalMixer(){ inv = new InventoryBasic("Chemical Mixer", false, 3); } the inv gets a new Inventory? Here the Error: [12:29:36] [server thread/FATAL]: Error executing task java.util.concurrent.ExecutionException: java.lang.NullPointerException at java.util.concurrent.FutureTask.report(Unknown Source) ~[?:1.8.0_101] at java.util.concurrent.FutureTask.get(Unknown Source) ~[?:1.8.0_101] at net.minecraft.util.Util.runTask(Util.java:24) [util.class:?] at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:738) [MinecraftServer.class:?] at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:683) [MinecraftServer.class:?] at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:155) [integratedServer.class:?] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:532) [MinecraftServer.class:?] at java.lang.Thread.run(Unknown Source) [?:1.8.0_101] Caused by: java.lang.NullPointerException at me.darki.chemmix.containers.ContainerChemicalMixer.<init>(ContainerChemicalMixer.java:18) ~[ContainerChemicalMixer.class:?] at me.darki.chemmix.guis.GuiHandler.getServerGuiElement(GuiHandler.java:19) ~[GuiHandler.class:?] at net.minecraftforge.fml.common.network.NetworkRegistry.getRemoteGuiContainer(NetworkRegistry.java:244) ~[NetworkRegistry.class:?] at net.minecraftforge.fml.common.network.internal.FMLNetworkHandler.openGui(FMLNetworkHandler.java:80) ~[FMLNetworkHandler.class:?] at net.minecraft.entity.player.EntityPlayer.openGui(EntityPlayer.java:2693) ~[EntityPlayer.class:?] at me.darki.chemmix.blocks.BlockChemicalMixer.onBlockActivated(BlockChemicalMixer.java:36) ~[blockChemicalMixer.class:?] at net.minecraft.server.management.PlayerInteractionManager.processRightClickBlock(PlayerInteractionManager.java:473) ~[PlayerInteractionManager.class:?] at net.minecraft.network.NetHandlerPlayServer.processRightClickBlock(NetHandlerPlayServer.java:706) ~[NetHandlerPlayServer.class:?] at net.minecraft.network.play.client.CPacketPlayerTryUseItem.processPacket(CPacketPlayerTryUseItem.java:68) ~[CPacketPlayerTryUseItem.class:?] at net.minecraft.network.play.client.CPacketPlayerTryUseItem.processPacket(CPacketPlayerTryUseItem.java:13) ~[CPacketPlayerTryUseItem.class:?] at net.minecraft.network.PacketThreadUtil$1.run(PacketThreadUtil.java:15) ~[PacketThreadUtil$1.class:?] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) ~[?:1.8.0_101] at java.util.concurrent.FutureTask.run(Unknown Source) ~[?:1.8.0_101] at net.minecraft.util.Util.runTask(Util.java:23) ~[util.class:?] ... 5 more and here the updated constructor: public ContainerChemicalMixer(IInventory inv, TileEntityChemicalMixer tileentity) { this.tileentiy = tileentity; this.addSlotToContainer(new Slot(tileentity.inv, 0, 30, 17)); this.addSlotToContainer(new Slot(tileentity.inv, 1, 130, 17)); this.addSlotToContainer(new OutputSlot(tileentity.inv, 2, 80, 51)); // Player Inventory, Slot 9-35, Slot IDs 9-35 for (int y = 0; y < 3; ++y) { for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(inv, x + y * 9 + 9, 8 + x * 18, 84 + y * 18)); } } // Player Inventory, Slot 0-8, Slot IDs 36-44 for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(inv, x, 8 + x * 18, 142)); } }

Oh I see it I have to make addSlot (tileentity.inventory...)

No here the same the like before:

Ok that wasnt in the Tutorial...now I added it: public class BlockChemicalMixer extends BasicBlock{ public BlockChemicalMixer() { super(Material.rock, "chemicalmixer", 10F, Tool.PICKAXE, HarvestLevel.IRON); isBlockContainer = true; } @Override public TileEntity createTileEntity(World world, IBlockState state) { return new TileEntityChemicalMixer(); } @Override public boolean hasTileEntity() { return true; } @Override public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumHand hand, ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ) { if(!world.isRemote){ player.openGui(Main.INSTANCE, GuiHandler.GUI_ID, world, pos.getX(), pos.getY(), pos.getZ()); } return true; } } is it right now?

Hm I didnt do this wrong so you said...I did it...or not? I watched a Tutorial...and this is the solution from the Tutorial

Ok...Is it possible, when I save the Inventory of the GUI in the NBTList (in TileEntity Class) save also the Blockpos of the Machine...so that I can identify the Gui to the BlockPos

Ok I try it. but i instantitate the TileEntity in the Container Class: private TileEntityChemicalMixer tileentiy; And then: public ContainerChemicalMixer(IInventory inv, TileEntityChemicalMixer tileentity) { this.tileentiy = tileentity; this.addSlotToContainer(new Slot(inv, 36, 30, 17)); this.addSlotToContainer(new Slot(inv, 37, 130, 17)); this.addSlotToContainer(new OutputSlot(inv, 38, 80, 51)); // Player Inventory, Slot 9-35, Slot IDs 9-35 for (int y = 0; y < 3; ++y) { for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(inv, x + y * 9 + 9, 8 + x * 18, 84 + y * 18)); } } // Player Inventory, Slot 0-8, Slot IDs 36-44 for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(inv, x, 8 + x * 18, 142)); } }

Of Course I instantitate my TileEntity in the GUI Handler: public class GuiHandler implements IGuiHandler{ public static final int GUI_ID = 0; @Override public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) { if (ID == GUI_ID) return new ContainerChemicalMixer(player.inventory, (TileEntityChemicalMixer) world.getTileEntity(new BlockPos(x, y, z))); else if (ID == GUI_ID + 1) return new ContainerGenerator(player.inventory, (TileEntityGenerator) world.getTileEntity(new BlockPos(x, y, z))); return null; } @Override public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) { if (ID == GUI_ID) return new GuiChemicalMixer(new ContainerChemicalMixer(player.inventory, (TileEntityChemicalMixer) world.getTileEntity(new BlockPos(x, y, z)))); else if (ID == GUI_ID + 1) return new GuiGenerator(new ContainerGenerator(player.inventory, (TileEntityGenerator) world.getTileEntity(new BlockPos(x, y, z)))); return null; } }

This is my Block Class: public class BlockChemicalMixer extends BasicBlock{ public BlockChemicalMixer() { super(Material.rock, "chemicalmixer", 10F, Tool.PICKAXE, HarvestLevel.IRON); } @Override public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumHand hand, ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ) { if(!world.isRemote){ player.openGui(Main.INSTANCE, GuiHandler.GUI_ID, world, pos.getX(), pos.getY(), pos.getZ()); } return true; } } Nothing special. When you ask for the BasicBlock class here: public class BasicBlock extends Block{ public BasicBlock(Material m, String name, float hardness, Tool tool, HarvestLevel level) { super(m); setUnlocalizedName(name); setRegistryName(name); setHardness(hardness); setCreativeTab(Main.chemTab); setHarvestLevel(tool.getToolClass(), level.getLevel()); } enum HarvestLevel{ WOOD(0), STONE(1), IRON(2), GOLD(0), DIAMOND(3); private int level; private HarvestLevel(int level) { this.level = level; } private int getLevel(){ return this.level; } } enum Tool{ PICKAXE("pickaxe"), AXE("axe"), HOE("hoe"), SHOVEL("shovel"); private String toolClass; private Tool(String toolClass) { this.toolClass = toolClass; } private String getToolClass(){ return this.toolClass; } } }

Hi, I am making a machine. With a GUI Container, the Container is working and also the TileEntity but now I see that when you place the machine twice the machines have the same TileEntity, so that in both machine are the same Inventories and Items. Here my Codes: TileEntity: public class TileEntityChemicalMixer extends TileEntity{ public InventoryBasic INVENTORY; private static int ID = 0; public TileEntityChemicalMixer(){ INVENTORY = new InventoryBasic("Chemical Mixer", false, 3); } @Override public void writeToNBT(NBTTagCompound compound) { super.writeToNBT(compound); NBTTagList list = new NBTTagList(); for(int i = 0; i < INVENTORY.getSizeInventory(); i++){ if(INVENTORY.getStackInSlot(i) != null){ NBTTagCompound tag = new NBTTagCompound(); tag.setByte("Slot", (byte) i); INVENTORY.getStackInSlot(i).writeToNBT(tag); list.appendTag(tag); } } compound.setTag("ItemStacks-" + ID, list); } @Override public void readFromNBT(NBTTagCompound compound) { super.readFromNBT(compound); NBTTagList list = compound.getTagList("ItemStacks-" + ID, 10); this.INVENTORY = new InventoryBasic("Chemical Mixer", false, 3); for(int i = 0; i < list.tagCount(); i++){ NBTTagCompound tag = list.getCompoundTagAt(i); byte b = tag.getByte("Slot"); if(b >= 0 && b < INVENTORY.getSizeInventory()){ INVENTORY.setInventorySlotContents(b, ItemStack.loadItemStackFromNBT(tag)); } } } } Container: public class ContainerChemicalMixer extends Container{ private TileEntityChemicalMixer tileentiy; public ContainerChemicalMixer(IInventory inv, TileEntityChemicalMixer tileentity) { this.tileentiy = tileentity; this.addSlotToContainer(new Slot(inv, 36, 30, 17)); this.addSlotToContainer(new Slot(inv, 37, 130, 17)); this.addSlotToContainer(new OutputSlot(inv, 38, 80, 51)); // Player Inventory, Slot 9-35, Slot IDs 9-35 for (int y = 0; y < 3; ++y) { for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(inv, x + y * 9 + 9, 8 + x * 18, 84 + y * 18)); } } // Player Inventory, Slot 0-8, Slot IDs 36-44 for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(inv, x, 8 + x * 18, 142)); } } @Override public boolean canInteractWith(EntityPlayer playerIn) { return true; } @Override public ItemStack transferStackInSlot(EntityPlayer playerIn, int fromSlot) { ItemStack previous = null; Slot slot = (Slot) this.inventorySlots.get(fromSlot); if (slot != null && slot.getHasStack()) { ItemStack current = slot.getStack(); previous = current.copy(); if (fromSlot < 9) { // From TE Inventory to Player Inventory if (!this.mergeItemStack(current, 9, 37, true)) return null; } else { // From Player Inventory to TE Inventory if (!this.mergeItemStack(current, 0, 9, false)) return null; } if (current.stackSize == 0) slot.putStack((ItemStack) null); else slot.onSlotChanged(); if (current.stackSize == previous.stackSize) return null; slot.onPickupFromSlot(playerIn, current); } return previous; } }

Ahhh thanks...wow that was a bit stupid

I have a Bug with my GUI Container...I want to make a Machine but there is a Bug with the Slots. I have a little Video from the Bug, here you can see: And here is the Code: TileEntity: public class TileEntityChemicalMixer extends TileEntity{ public InventoryBasic INVENTORY; public TileEntityChemicalMixer(){ INVENTORY = new InventoryBasic("Chemical Mixer", false, 3); } @Override public void writeToNBT(NBTTagCompound compound) { super.writeToNBT(compound); NBTTagList list = new NBTTagList(); for(int i = 0; i < INVENTORY.getSizeInventory(); i++){ if(INVENTORY.getStackInSlot(i) != null){ NBTTagCompound tag = new NBTTagCompound(); tag.setByte("Slot", (byte) i); INVENTORY.getStackInSlot(i).writeToNBT(tag); list.appendTag(tag); } } compound.setTag("ItemStacks", list); } @Override public void readFromNBT(NBTTagCompound compound) { super.readFromNBT(compound); NBTTagList list = compound.getTagList("ItemStacks", 10); this.INVENTORY = new InventoryBasic("Chemical Mixer", false, 3); for(int i = 0; i < list.tagCount(); i++){ NBTTagCompound tag = list.getCompoundTagAt(i); byte b = tag.getByte("Slot"); if(b >= 0 && b < INVENTORY.getSizeInventory()){ INVENTORY.setInventorySlotContents(b, ItemStack.loadItemStackFromNBT(tag)); } } } } Container: public class ContainerChemicalMixer extends Container{ private TileEntityChemicalMixer tileentiy; public ContainerChemicalMixer(IInventory inv, TileEntityChemicalMixer tileentity) { this.tileentiy = tileentity; this.addSlotToContainer(new Slot(inv, 0, 30, 17)); this.addSlotToContainer(new Slot(inv, 0, 130, 17)); // Player Inventory, Slot 9-35, Slot IDs 9-35 for (int y = 0; y < 3; ++y) { for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(inv, x + y * 9 + 9, 8 + x * 18, 84 + y * 18)); } } // Player Inventory, Slot 0-8, Slot IDs 36-44 for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(inv, x, 8 + x * 18, 142)); } } @Override public boolean canInteractWith(EntityPlayer playerIn) { return true; } } And GUI: public class GuiChemicalMixer extends GuiContainer{ public static final ResourceLocation BACKGROUND = new ResourceLocation(Main.MODID + ":textures/gui/chemicalmixergui.png"); public GuiChemicalMixer(Container inventorySlotsIn) { super(inventorySlotsIn); this.ySize = 166; this.xSize = 176; } @Override protected void drawGuiContainerBackgroundLayer(float partialTicks, int mouseX, int mouseY) { mc.renderEngine.bindTexture(BACKGROUND); int k = (this.width - this.xSize) / 2; int l = (this.height - this.ySize) / 2; drawTexturedModalRect(k, l, 0, 0, xSize, ySize); } }

I found it but the tnt makes only a half heart damage can I change it so that the player dies instantly

How can I spawn a Primed TNT over Players head? I know that I have to do something like that: EntityTNTPrimed tnt = new EntityTNTPrimed(w); tnt.fuse = 0; w.spawnEntityInWorld(tnt); But with this the TNT will spawning anywhere

Thanks^^

I would like to know how can I change Items to another Item. E.g.: You have a Iron Ingot, then you right click it and the Iron Ingot will removed and a Gold Ingot is there where the Iron Ingot was

Yeah...Thanks a lot to all people^^

I know how programming works but I never do GUIs

Yes but how can I find out the location and how I have to paste them in the addSlot method?!

I mean the Locations where later the 2 slots should be in the GUI

Yes but how can I do this? From where I have to start counting the pixels

Yes but I dont know how to find the location.

Hey I am working on a Generator and I took the Furnace Gui, but I deleted the Output slot. So my Question is, how can I add the two slots on this picture: I know I have to do something like that: for(j = 0; j < 3; j++){ for(k = 0; k < 3; k++){ this.addSlotToContainer(new Slot(tileEntity.inventory, index++, 29 + k * 16 , 17 + j * 18)); } } But I don't know how I write the right Slot pos like in the code after index++.

Do someone know how I can use the RedstoneFlux API?! Is there a Tutorial or a Wiki? How can I transfer Energy throw my Pipes? And How can I connect Machines with the pipes? And How I make e.g. a solarpanel to a provider and a machine to a receiver

Thanks. I think to make the Energy System I look into the Code of Team CoFH's RedstoneFlux API
