hey, I want to add oil and it should be compatible with buildcraft oil. Could I play with 2 oils at the same time? And if not, how can I activate buildcraft oil if buildcraft is installed? ModFluids public class ModFluids { public static final Fluid oil = new Fluid("oil").setDensity(800) .setViscosity(10000); public static void init() { registerFluid(ModFluids.oil, "oil"); } private static void registerFluid(Fluid fluid, String fluidName) { if (!FluidRegistry.isFluidRegistered(fluidName)) { FluidRegistry.registerFluid(fluid); } fluid = FluidRegistry.getFluid(fluidName); } } ModBlocks public class ModBlocks { public static final Block oilBlock = new OilBlock(ModFluids.oil, Material.water); public static void init() { GameRegistry.registerBlock(oilBlock, "oilBlock"); } } Moditems public class ModItems { public static final Item oilBucket = new OilBucket(ModBlocks.oilBlock); public static void init() { GameRegistry.registerItem(oilBucket, "oilBucket"); FluidContainerRegistry.registerFluidContainer(FluidRegistry.getFluidStack("oil", FluidContainerRegistry.BUCKET_VOLUME), new ItemStack(oilBucket), new ItemStack(Items.bucket)); BucketHandler.INSTANCE.buckets.put(ModBlocks.oilBlock, ModItems.oilBucket); } }

I have a TE class with this method: @Override public void updateEntity() { if (worldObj.isRemote) return; Vector<EntityPlayer> lis = new Vector<EntityPlayer>(); for (World w : MinecraftServer.getServer().worldServers) for (Object o : w.playerEntities) { EntityPlayer p = (EntityPlayer) o; lis.add(p); } for (EntityPlayer player : lis) { if (new Random().nextInt(5) == 2) { EntityItem ei = new EntityItem(worldObj, player.posX, player.posY, player.posZ, Mod.foodList.get(5)); worldObj.spawnEntityInWorld(ei); System.out.println("num: " + ei.getEntityItem().stackSize); } } } the foodList is initialized in postInit(FMLPostInitializationEvent event): foodList = new Vector<ItemStack>(); Iterator<Item> f = GameData.getItemRegistry().iterator(); while (f.hasNext()) { Item i = f.next(); if (i instanceof ItemFood) { ItemFood item = (ItemFood) i; if (i.getHasSubtypes()) { i.getSubItems(i, null, foodList); } else foodList.add(new ItemStack(i)); } } the output: [16:59:22] [server thread/INFO]: Player579 joined the game [16:59:23] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 1 [16:59:23] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 1 [16:59:23] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 1 [16:59:24] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 1 [16:59:24] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 1 [16:59:24] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 1 [16:59:24] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 2 [16:59:24] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 2 [16:59:24] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 2 [16:59:25] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 16 [16:59:25] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 16 [16:59:25] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 64 [16:59:25] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 64 [16:59:26] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 0 [16:59:27] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 0 [16:59:27] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 0 [16:59:27] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 0 [16:59:27] [server thread/INFO] [sTDOUT]: [mrriegel.cwacom.tile.TileTerminal:updateEntity:93]: num: 0 then the 0 is repeating. sometimes it starts with 0 or jump from 1 to 0. when I replace "Mod.foodList.get(5)" with e.g. "new ItemStack(Items.golden_apple)" everything is fine and the stacksize is 1 So, whats wrong?

hey, I need to sync TE on client and server side because changes only occur on server side. I use getDescriptionPacket() and onDataPacket(). The problem is that TE implements ISidedInventory and I cannot sync the stacks from ItemStack[] if the stack is null, but that is necessary. If I clear the inventory on server side the client doesn't care. @Override public void readFromNBT(NBTTagCompound tag) { super.readFromNBT(tag); NBTTagList invList = tag.getTagList("Inventory", Constants.NBT.TAG_COMPOUND); for (int i = 0; i < invList.tagCount(); i++) { NBTTagCompound stackTag = invList.getCompoundTagAt(i); int slot = stackTag.getByte("Slot"); if (slot >= 0 && slot < inv.length) inv[slot] = ItemStack.loadItemStackFromNBT(stackTag); } active = tag.getBoolean("active"); processing = tag.getBoolean("processing"); cooldown = tag.getInteger("cooldown"); name = tag.getString("name"); NBTTagCompound st = (NBTTagCompound) tag.getTag("stack"); stack = ItemStack.loadItemStackFromNBT(st); } @Override public void writeToNBT(NBTTagCompound tag) { super.writeToNBT(tag); NBTTagList invList = new NBTTagList(); for (int i = 0; i < inv.length; i++) { if (inv[i] != null) { NBTTagCompound stackTag = new NBTTagCompound(); stackTag.setByte("Slot", (byte) i); inv[i].writeToNBT(stackTag); invList.appendTag(stackTag); } } tag.setBoolean("active", active); tag.setBoolean("processing", processing); tag.setInteger("cooldown", cooldown); if (name != null && !name.equals("")) tag.setString("name", name); NBTTagCompound st = new NBTTagCompound(); if (stack != null) stack.writeToNBT(st); tag.setTag("stack", st); tag.setTag("Inventory", invList); } @Override public Packet getDescriptionPacket() { NBTTagCompound syncData = new NBTTagCompound(); this.writeToNBT(syncData); return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, 1, syncData); } @Override public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) { readFromNBT(pkt.func_148857_g()); worldObj.markBlockForUpdate(xCoord, yCoord, zCoord); }

hi, I want to render an texture (a png file) into an item in inventory. Rendering an item into another was easy with that. But how without an item?

thanks ItemStack#loadItemStackFromNBT(NBTTagCompound) is great

Hi, I made an item with an inventory with the aid of this tutorial http://www.minecraftforum.net/forums/mapping-and-modding/mapping-and-modding-tutorials/1571597-forge-1-6-4-1-8-custom-inventories-in-items-and?comment=1 Now I want to have a list of itemstack the inventory contains. But NBT can't save entire itemstacks. With stack.getTagCompound().getTagList("bag",stack.getTagCompound().getId()).getCompoundTagAt(0) I can get id,damage and stacksize but I don't know how to resolve this. thanks

the problem is that the nbt changes only on server side while the inventory is open. only if the inventory is closed the nbt on client side changes too. I tried to send packets in onUpdate() but it doesn't work.

you are a genius thanks

Hi Problem: Code: public class StoneItemRenderer extends TileEntitySpecialRenderer { private final RenderItem renderItem; public StoneItemRenderer() { renderItem = new RenderItem() { @Override public boolean shouldBob() { return false; } }; renderItem.setRenderManager(RenderManager.instance); } @Override public void renderTileEntityAt(TileEntity tileEntity, double d0, double d1, double d2, float f) { if (tileEntity instanceof MazerTile) { add(tileEntity, d0 + 1.3, d1, d2 + 1.3, f, 0); add(tileEntity, d0 - 1.3, d1, d2 - 1.3, f, 1); add(tileEntity, d0 + 1.3, d1, d2 - 1.3, f, 2); add(tileEntity, d0 - 1.3, d1, d2 + 1.3, f, 3); } } private void add(TileEntity tileEntity, double d0, double d1, double d2, float f, int slot) { MazerTile tile = (MazerTile) tileEntity; GL11.glPushMatrix(); if (tile.getStackInSlot(slot) != null) { float scaleFactor = 0.85F; float rotationAngle = Minecraft.getMinecraft().gameSettings.fancyGraphics ? (float) (720.0 * (System .currentTimeMillis() & 0x3FFFL) / 0x3FFFL) : 0; EntityItem ghostEntityItem = new EntityItem(tile.getWorldObj()); ghostEntityItem.hoverStart = 0.0F; ghostEntityItem.setEntityItemStack(tile.getStackInSlot(slot)); float displacement = 0.2F; if (ghostEntityItem.getEntityItem().getItem() instanceof ItemBlock) { GL11.glTranslatef((float) d0 + 0.5F, (float) d1 + displacement + 0.7F, (float) d2 + 0.5F); } else { GL11.glTranslatef((float) d0 + 0.5F, (float) d1 + displacement + 0.6F, (float) d2 + 0.5F); } GL11.glScalef(scaleFactor, scaleFactor, scaleFactor); GL11.glRotatef(rotationAngle, 0.0F, 1.0F, 0.0F); renderItem.doRender(ghostEntityItem, 0, 0, 0, 0, 0); } GL11.glPopMatrix(); } } thanks

hey guys, I want to implement waila support. My code: public class StoneHandler implements IWailaDataProvider { @Override public NBTTagCompound getNBTData(EntityPlayerMP arg0, TileEntity arg1, NBTTagCompound arg2, World arg3, int arg4, int arg5, int arg6) { if (!(arg1 instanceof MazerTile)) { return null; } return arg2; } @Override public List<String> getWailaBody(ItemStack itemStack, List<String> currenttip, IWailaDataAccessor accessor, IWailaConfigHandler config) { if (!(accessor.getTileEntity() instanceof MazerTile)) { return null; } MazerTile tile = (MazerTile) accessor.getTileEntity(); currenttip.add("Active: " + tile.isActive()); return currenttip; } @Override public List<String> getWailaHead(ItemStack arg0, List<String> arg1, IWailaDataAccessor arg2, IWailaConfigHandler arg3) { return arg1; } @Override public ItemStack getWailaStack(IWailaDataAccessor arg0, IWailaConfigHandler arg1) { return null; } @Override public List<String> getWailaTail(ItemStack arg0, List<String> arg1, IWailaDataAccessor arg2, IWailaConfigHandler arg3) { return arg1; } public static void callbackRegister(IWailaRegistrar registrar) { registrar.registerBodyProvider(new StoneHandler(), MazerTile.class); } } The problem I dont know how to get data from server side because waila method are only called on client side. I could use SimpleNetworkWrapper but in what class do I synchronize? Block and TileEntity classes have no onUpdate() method.

hey, I made a sword with an inventory with one slot. the texture of the sword depends on the containing item. @Override public IIcon getIconFromDamage(int p_77617_1_) { if (sword .getTagCompound() .getTagList(InventoryNevTool.tagName, sword.getTagCompound().getId()).getCompoundTagAt(0) .getShort("Damage") == 6) { return icon_f; } else { return itemIcon; } } but while the gui is open and changing the item, the sword icon is flickering. https://drive.google.com/file/d/0Bxk8bebSTRk-LVN5YWhIWDF0RWc/view?usp=sharing how can I stop this?

Hey guys, I made new tools and I want to make them unenchantable. By overriding getItemEnchantability() with return 0; I can make them unenchantable in the enchanting table but enchanting with books works anyway

@SubscribeEvent public void kill(LivingDeathEvent event) { if (event.source.getSourceOfDamage() instanceof EntityPlayer) { EntityPlayer player = (EntityPlayer) source.getSourceOfDamage(); doSomethingWithPlayer(player); } }

What is more efficient in case that equals gives true? if(!world.getBlock(x,y,z).equals(Blocks.example){ world.setBlock(x,y,z,Blocks.example); } or world.setBlock(x,y,z,Blocks.example);

It works! I would not have thought that it is so easy. thank you

hello, I want to save data to player and I use IEEP. So far, so good. The data survive logout and death. But when I go from death screen directly to title screen the data is lost. How can I fix this?

ok thanks

I did it with getDeclaredFields() not handwritten

too late https://github.com/MrRiegel/Blocked-Layers/blob/1.7.10/src/main/java/mrriegel/blockedlayers/utility/Hashmaps.java but thanks

Thats the way I want to avoid. But if there is no other possibility, I go for it. Yay, 170 Items,170 Blocks, 30 Entities. That would be very easy. </irony> Thanks

hey there! here is my problem: I want to make a little quest mod, where the user can write own quests to a file with a simple syntax("addQuest(kill,zombie,5)"). The parsing of the file is easy, but how can I get the class EntityZombie from the string "zombie" or the Items.apple from the string "apple"? It works with Items.class.getDeclaredFields() or ClassLoader, but ONLY in eclipse because the item names in "real life" are e.g. field_345_3. Thanks
