Not too much As i said i'm really new to nbt tags so i'm not sure how to use them Anyway i removed that line, so i now have this for(int i = 0; i < list.size(); i++) { NBTTagCompound compound = result.getSubCompound("BlockEntityTag", true); NBTTagList nbttaglist = new NBTTagList(); NBTTagCompound nbttagcompound1 = new NBTTagCompound(); nbttagcompound1.setByte("Slot", (byte)0); new ItemStack(list.get(i)).writeToNBT(nbttagcompound1); nbttaglist.appendTag(nbttagcompound1); nbttagcompound1.setTag("Items", nbttaglist); manager.addRecipe(result, new Object[] {"###", "#I#", "###", '#', Blocks.wool, 'I', new ItemStack(list.get(i))}); } And what the crafting result give is this so an nbt tag is applied but is not the nbt tag that i want since the chest is still empty

Sooo... should i do this? NBTTagCompound compound = result.getSubCompound("BlockEntityTag", true); NBTTagList nbttaglist = new NBTTagList(); NBTTagCompound nbttagcompound1 = new NBTTagCompound(); nbttagcompound1.setByte("Slot", (byte)0); new ItemStack(list.get(i)).writeToNBT(nbttagcompound1); nbttaglist.appendTag(nbttagcompound1); nbttagcompound1.setTag("Items", nbttaglist); result.setTagCompound(nbttagcompound1);

Ok, i've changed that to this NBTTagCompound compound = result.getSubCompound("BlockEntityTag", true); NBTTagList nbttaglist = new NBTTagList(); NBTTagCompound nbttagcompound1 = new NBTTagCompound(); nbttagcompound1.setByte("Slot", (byte)0); new ItemStack(list.get(i)).writeToNBT(nbttagcompound1); nbttaglist.appendTag(nbttagcompound1); compound.setTag("Items", nbttaglist); result.setTagCompound(compound); but still doesn't work

Quick update: for the recipe i come to this ItemStack result = new ItemStack(MWBlocks.gift); manager.addRecipe(new ItemStack(MWBlocks.gift), new Object[] {"###", "# #", "###", '#', Blocks.wool}); for(int i = 0; i < list.size(); i++) { NBTTagCompound compound = new NBTTagCompound(); NBTTagList nbttaglist = new NBTTagList(); NBTTagCompound nbttagcompound1 = new NBTTagCompound(); nbttagcompound1.setByte("Slot", (byte)0); new ItemStack(list.get(i)).writeToNBT(nbttagcompound1); nbttaglist.appendTag(nbttagcompound1); compound.setTag("Items", nbttaglist); result.setTagCompound(compound); manager.addRecipe(result, new Object[] {"###", "#I#", "###", '#', Blocks.wool, 'I', list.get(i)}); } so i've got 2 recipes, one for the standard chest and one including the additional item or block, and it works, execpt for the fact that the item isn't in the chest when placed down

I've looked into the TileEntityChest class and see how the writeToNBT function works. So just for test i've tried doing this, to give a chest filled with a diamond shovel in result of crafting ItemStack stack = new ItemStack(MWBlocks.gift); ItemStack shovel = new ItemStack(Items.diamond_shovel); NBTTagCompound compound = new NBTTagCompound(); NBTTagList nbttaglist = new NBTTagList(); NBTTagCompound nbttagcompound1 = new NBTTagCompound(); nbttagcompound1.setByte("Slot", (byte)0); shovel.writeToNBT(nbttagcompound1); nbttaglist.appendTag(nbttagcompound1); compound.setTag("Items", nbttaglist); stack.setTagCompound(compound); GameRegistry.addRecipe(stack, new Object[] {this.recipePattern[0], 'X', Blocks.wool}); using F3+H it says that the chest given in result has 1 nbt tag but when placed down is empty

yes, i've readed it, but i'm sorry because i've never worked with nbt tags So far i know that i should do this ItemStack stack = new ItemStack(MWBlocks.gift); NBTTagCompound nbttag = new NBTTagCompound(); stack.setTagCompound(nbttag); but what i don't know is how to set the chest content (if any). Because the crafting should give in result an empty chest if no item/block is in the middle, a chest with the entire stack of the items/blocks in the middle if there are (so for example, if there are 32 diamonds in the middle slot it should return a chest with 32 diamonds inside) and it should work with any items (so i don't know before wich items should go in the middle slot)

mmm, so i've looked how the craftings for banners works, and so i do this package mw.craftings; import mw.core.MWBlocks; import net.minecraft.init.Blocks; import net.minecraft.init.Items; import net.minecraft.inventory.InventoryCrafting; import net.minecraft.item.EnumDyeColor; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.item.crafting.CraftingManager; import net.minecraft.item.crafting.IRecipe; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.nbt.NBTTagList; import net.minecraft.tileentity.TileEntityBanner; import net.minecraft.world.World; public class CraftingGifts { public void func_179534_a(CraftingManager manager) { manager.addRecipe(new ItemStack(MWBlocks.gift, 1), new Object[] {"###", "# #", "###", '#', new ItemStack(Item.getItemFromBlock(Blocks.wool), 1)}); manager.addRecipe(new CraftingGifts.AddItemToGift(null)); } public static class AddItemToGift implements IRecipe { private AddItemToGift() {} /** * Used to check if a recipe matches current crafting inventory */ public boolean matches(InventoryCrafting inventory, World worldIn) { boolean flag = false; for (int i = 0; i < inventory.getSizeInventory(); ++i) { ItemStack itemstack = inventory.getStackInSlot(i); if (itemstack != null && itemstack.getItem() == Item.getItemFromBlock(MWBlocks.gift)) { if (flag) { return false; } flag = true; } } return flag; } /** * Returns an Item that is the result of this recipe */ public ItemStack getCraftingResult(InventoryCrafting inventory) { ItemStack itemstack = null; for (int i = 0; i < inventory.getSizeInventory(); ++i) { ItemStack itemstack1 = inventory.getStackInSlot(i); if (itemstack1 != null && itemstack1.getItem() == Item.getItemFromBlock(MWBlocks.gift)) { itemstack = itemstack1.copy(); itemstack.stackSize = 1; break; } } int k = 0; ItemStack itemstack2; for (int j = 0; j < inventory.getSizeInventory(); ++j) { itemstack2 = inventory.getStackInSlot(j); if (itemstack2 != null) { k = itemstack2.getMetadata(); break; } } NBTTagCompound nbttagcompound1 = itemstack.getSubCompound("BlockEntityTag", true); itemstack2 = null; NBTTagList nbttaglist; nbttaglist = new NBTTagList(); nbttagcompound1.setTag("Items", nbttaglist); NBTTagCompound nbttagcompound = new NBTTagCompound(); nbttagcompound.setByte("Sloy", (byte)0); nbttaglist.appendTag(nbttagcompound); return itemstack; } /** * Returns the size of the recipe area */ public int getRecipeSize() { return 10; } public ItemStack getRecipeOutput() { return null; } public ItemStack[] getRemainingItems(InventoryCrafting p_179532_1_) { ItemStack[] aitemstack = new ItemStack[p_179532_1_.getSizeInventory()]; for (int i = 0; i < aitemstack.length; ++i) { ItemStack itemstack = p_179532_1_.getStackInSlot(i); aitemstack[i] = net.minecraftforge.common.ForgeHooks.getContainerItem(itemstack); } return aitemstack; } private TileEntityBanner.EnumBannerPattern func_179533_c(InventoryCrafting p_179533_1_) { TileEntityBanner.EnumBannerPattern[] aenumbannerpattern = TileEntityBanner.EnumBannerPattern.values(); int i = aenumbannerpattern.length; for (int j = 0; j < i; ++j) { TileEntityBanner.EnumBannerPattern enumbannerpattern = aenumbannerpattern[j]; if (enumbannerpattern.hasValidCrafting()) { boolean flag = true; int i1; if (enumbannerpattern.hasCraftingStack()) { boolean flag1 = false; boolean flag2 = false; for (i1 = 0; i1 < p_179533_1_.getSizeInventory() && flag; ++i1) { ItemStack itemstack1 = p_179533_1_.getStackInSlot(i1); if (itemstack1 != null && itemstack1.getItem() != Items.banner) { if (itemstack1.getItem() == Items.dye) { if (flag2) { flag = false; break; } flag2 = true; } else { if (flag1 || !itemstack1.isItemEqual(enumbannerpattern.getCraftingStack())) { flag = false; break; } flag1 = true; } } } if (!flag1) { flag = false; } } else if (p_179533_1_.getSizeInventory() != enumbannerpattern.getCraftingLayers().length * enumbannerpattern.getCraftingLayers()[0].length()) { flag = false; } else { int k = -1; for (int l = 0; l < p_179533_1_.getSizeInventory() && flag; ++l) { i1 = l / 3; int j1 = l % 3; ItemStack itemstack = p_179533_1_.getStackInSlot(l); if (itemstack != null && itemstack.getItem() != Items.banner) { if (itemstack.getItem() != Items.dye) { flag = false; break; } if (k != -1 && k != itemstack.getMetadata()) { flag = false; break; } if (enumbannerpattern.getCraftingLayers()[i1].charAt(j1) == 32) { flag = false; break; } k = itemstack.getMetadata(); } else if (enumbannerpattern.getCraftingLayers()[i1].charAt(j1) != 32) { flag = false; break; } } } if (flag) { return enumbannerpattern; } } } return null; } AddItemToGift(Object p_i45780_1_) { this(); } } } but nothing changes, i get the chest (the gift) in result of normal crafting but when i add an item in the middle of the crafting table i get nothing in result of crafting

For example, i have a crafting recipe like this how can i return in result of the crafting a chest but with already the item in the central slot inside, so when the chest is placed down it has this item inside?

I understand For the block part i have done it with a tile entity that only store the player UUID, it doesn't do anything else. For the redstone part, i think i should handle multiple events (entity collides with a pressur plate, entity interact with a lever/button, ...) and in there check if is a player who activate them. For multiple player instances, once the player hits the pressure plate is done, is not a block that works "until the player is on the pressure plate", it just need a single impulse of any type, so in that case both players will receive the output because both have activated it. The hard part is to see if what they press (lever,pressure plate, ecc...) is connected to the block, wich i think is a bit hard to code and sure will require a good pc to run (wich is not good).

as for what i know (not to much really) you should have a "run" folder in to the main mod folder (or pearhaps a folder that looks like he minecraft folder). In here there is a folder called "mods", try putting the other mods there and see if they works

mmm, alright, i'll change it to work with a tile entity

Without using a TileEntity i have done this @Override public void onBlockPlacedBy(World world, BlockPos pos, IBlockState state, EntityLivingBase entity, ItemStack stack) { super.onBlockPlacedBy(world, pos, state, entity, stack); if(entity instanceof EntityPlayer) this.player = (EntityPlayer) entity; } saving the entity uuid in a local variable (this.player). Then in the onBlockAdded/onNeighborBlockChange functions i do this if(this.player != null) this.onBlockActivated(par1, pos, state, par1.getPlayerEntityByUUID(this.player), null, 0.0F, 0.0F, 0.0F); else this.onBlockActivated(par1, pos, state, par1.getClosestPlayer(pos.getX(), pos.getY(), pos.getZ(), 10.0F), null, 0.0F, 0.0F, 0.0F); so if a player place this block than only that player will have a message in chat, even if is not him to activate the block via redstone (it's weird and possibly wrong, but since it would be very disadvantaged check where a redstone circuit ends up, i'll leave this), and if it's not a player to place the block (for example via setblock command) than give the output to the closest player Thanks Choonster for giving me the tip to save the player uuid

So there's absolutely no way to find that? Maybe some event to handle?

I have a block that when powered by redstone (or anything related like buttons, levers....) or right clicked do some stuff and than send a message to the player in the chat. Now, for the right click no problem, the message is displayed only to who actually right clicked the block. BUt for the redstone related part? Since i don't know how to check (or even if it is possible to check) who placed/activated the block how can i send the right message to the right player? By now i check the nearest player to block, wich it works assuming that the only player in a radius of 5 blocks from the powered block is actually who powered the block. But of course i want to avoid this because if there is another player near the block, the chat message will be showned to that player instead of the "legal" one.

Ok, so updating the Forge version to the latest or the MC1.8 fixed the error For anyone who want an example, this is the actual code package com.example.examplemod; import net.minecraft.block.material.Material; import net.minecraft.block.state.IBlockState; import net.minecraft.client.renderer.ItemMeshDefinition; import net.minecraft.client.renderer.block.statemap.StateMapperBase; import net.minecraft.client.resources.model.ModelBakery; import net.minecraft.client.resources.model.ModelResourceLocation; import net.minecraft.creativetab.CreativeTabs; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.util.ResourceLocation; import net.minecraftforge.client.model.ModelLoader; import net.minecraftforge.fluids.BlockFluidClassic; import net.minecraftforge.fluids.Fluid; import net.minecraftforge.fluids.FluidRegistry; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.fml.common.Mod.EventHandler; import net.minecraftforge.fml.common.SidedProxy; import net.minecraftforge.fml.common.event.FMLPreInitializationEvent; import net.minecraftforge.fml.common.registry.GameRegistry; @Mod(modid = ModelFluidDebug.MODID, version = ModelFluidDebug.VERSION) public class ModelFluidDebug { public static final String MODID = "ForgeDebugModelFluid"; public static final String VERSION = "1.0"; private static ModelResourceLocation fluidLocation = new ModelResourceLocation(MODID.toLowerCase() + ":" + TestFluidBlock.name, "fluid"); private static ModelResourceLocation gasLocation = new ModelResourceLocation(MODID.toLowerCase() + ":" + TestFluidBlock.name, "gas"); @EventHandler public void preInit(FMLPreInitializationEvent event) { FluidRegistry.registerFluid(CustomFluid.instance); FluidRegistry.registerFluid(TestGas.instance); GameRegistry.registerBlock(TestFluidBlock.instance, TestFluidBlock.name); GameRegistry.registerBlock(TestGasBlock.instance, TestGasBlock.name); Item fluid = Item.getItemFromBlock(TestFluidBlock.instance); Item gas = Item.getItemFromBlock(TestGasBlock.instance); ModelBakery.addVariantName(fluid); ModelBakery.addVariantName(gas); ModelLoader.setCustomMeshDefinition(fluid, new ItemMeshDefinition() { public ModelResourceLocation getModelLocation(ItemStack stack) { return fluidLocation; } }); ModelLoader.setCustomMeshDefinition(gas, new ItemMeshDefinition() { public ModelResourceLocation getModelLocation(ItemStack stack) { return gasLocation; } }); ModelLoader.setCustomStateMapper(TestFluidBlock.instance, new StateMapperBase() { protected ModelResourceLocation getModelResourceLocation(IBlockState state) { return fluidLocation; } }); ModelLoader.setCustomStateMapper(TestGasBlock.instance, new StateMapperBase() { protected ModelResourceLocation getModelResourceLocation(IBlockState state) { return gasLocation; } });} public static final class CustomFluid extends Fluid { public static final String name = "myfluid"; public static final CustomFluid instance = new CustomFluid(); private CustomFluid() { super(name, new ResourceLocation(MODID.toLowerCase() + ":" + "blocks/testfluid"), new ResourceLocation(MODID.toLowerCase() + ":" + "blocks/testfluid")); } } public static final class TestGas extends Fluid { public static final String name = "testgas"; public static final TestGas instance = new TestGas(); private TestGas() { super(name, new ResourceLocation("blocks/lava_still"), new ResourceLocation("blocks/lava_flow")); density = -1000; isGaseous = true; } } public static final class TestFluidBlock extends BlockFluidClassic { public static final TestFluidBlock instance = new TestFluidBlock(); public static final String name = "TestFluidBlock"; private TestFluidBlock() { super(CustomFluid.instance, Material.water); setCreativeTab(CreativeTabs.tabBlock); setUnlocalizedName(MODID + ":" + name); } @Override public int getRenderType() { return 3; } /** * The type of render function that is called for this block */ } public static final class TestGasBlock extends BlockFluidClassic { public static final TestGasBlock instance = new TestGasBlock(); public static final String name = "TestGasBlock"; private TestGasBlock() { super(TestGas.instance, Material.lava); setCreativeTab(CreativeTabs.tabBlock); setUnlocalizedName(MODID + ":" + name); } } } and this is the Json file { "forge_marker": 1, "variants": { "fluid": { "model": "forge:fluid", "custom": { "fluid": "myfluid" } }, "gas": { "model": "forge:fluid", "custom": { "fluid": "testgas" } } } } Note that the name specified in "custom" in the json file is the same name as specified in the class, otherwise it will have the default water texture Thanks Choonster for the tip

Actually i had to test it in a newer version of Forge and see if it works As soon as i can i'll let you kow

ahahahah that was just a copy/paste from the github file, in fact in the mod where this will go it's lower case

Mmm... i'm using the 1.8-11.14.1.1375 version, i'll try it in that version

I do this in the ModelResourceLocation MODID.toLowerCase() so it's always lower case when passed as argument to ModelResourceLocation ctor

bump

Still any idea?

Anybody? I don't understand why the fluid when placed down is invisible UPDATE: i've added this to the TestFluidBlock class @Override public int getRenderType() { return 3; } and now it gives me this So apparently is not spreading like the normal water does, it fills all the space with "blocks", is because it has no texture? How can i give it one?

So i've tried looking at the ModelFluidDebug class here https://github.com/MinecraftForge/MinecraftForge/blob/b45fd787f36626ef84f26e881848167fec5957b5/src/test/java/net/minecraftforge/debug/ModelFluidDebug.java but is not working I have done a new workspace with only that file (so basically a mod that adds only that fluid) but the texture is missing.

Thanks, now is working And yes, i know it's still in early development but for what i'm doing it should be fine (just adding some blocks, items, ores and mobs)

So last night i went to files.minecraftforge.net to download a newer version of Forge for 1.8. What i found out was a version even newer wich is for Minecraft 1.8.8. So i've downloaded and try to install like forge 1.8, but the installation has failed I've checked the build file at lines 36 (where it says there is an error), i didn't modified that. What is written there is this mappings = "snapshot_20141130" Here are a couple o pics to see what the console gives when trying to do the setupDecompWorkspace command https://imgur.com/a/0R7d9 Is this a bug with this version of Forge or am i doing something wrong?
