and where is FoodStats?

I will work in a Mod that haves four new bars and they works like the hugry bar, I need the codes of that bar, where I find that class?

ok, thanks all, for now, I will ask you a last thing, where I learn Java?

ItemStack constructor? you mean to ItemStack.java or to the codes with "ItemStack". Sequituri: You won the bet, I don't program in Java much, that's the reason why I'm in this forum

I finded two code lines that make mention to the ItemStack in the crash report: at net.minecraft.item.ItemStack.<init>(ItemStack.java:82) both says the same thing but I don't find the object that's null

sorry for the second topic, but, what I must do?

yes, sorry, I forget the crash report, this is: ---- Minecraft Crash Report ---- // Hey, that tickles! Hehehe!

appear the same problem, this is the code: package source.items; import net.minecraft.block.Block; import net.minecraft.client.renderer.texture.IconRegister; import net.minecraft.item.EnumToolMaterial; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.item.ItemSword; import cpw.mods.fml.common.registry.GameRegistry; import cpw.mods.fml.common.registry.LanguageRegistry; public class Items { public static void init() { EspadaDeObsidiana = new ItemSword(ItemInfo.WAND_ID, EnumToolMaterial.EMERALD).setUnlocalizedName("EspadaDeObsidiana"); } public static Item EspadaDeObsidiana; public static void addNames() { LanguageRegistry.addName(new ItemStack(EspadaDeObsidiana, 1), ItemInfo.WAND_NAME); } public void registerIcons(IconRegister icon) { icon.registerIcon(ItemInfo.WAND_ID + ":" + setUnlocalizedName().substring(5)); } public static void registerRecipes() { GameRegistry.addRecipe(new ItemStack (EspadaDeObsidiana, 1), new Object[] { " O ", " O ", " / ", 'O', Block.obsidian, '/', Item.stick, }); } }

like a good Modder, I made a count in adf.ly but I don't know if I can trust in them because they ask for my direction, and that is not secure, so I ask you if do that is secure

well, I been looking a crowd of Mods and they are very... complex like Galacticraft, IndustrialCraft, Buildcraft or LotsOMobs, so, I think I can do everything in the Mods if I have the correct methods, fields and classes, but, how I do them?

How I give a texture to my items? and, how to give them their durability? Thanks. Eaglenator

package example.items; import net.minecraft.block.Block; import net.minecraft.item.EnumToolMaterial; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.item.ItemSword; import cpw.mods.fml.common.registry.GameRegistry; import cpw.mods.fml.common.registry.LanguageRegistry; public class Items { public static void init() { EspadaDeObsidiana = new ItemSword(ItemInfo.WAND_ID, EnumToolMaterial); } public static Item EspadaDeObsidiana; public static void addNames() { LanguageRegistry.addName(new ItemStack(EspadaDeObsidiana, 1), ItemInfo.WAND_NAME); } public static void registerRecipes() { GameRegistry.addRecipe(new ItemStack (EspadaDeObsidiana, 1), new Object[] { " O ", " O ", " / ", 'O', Block.obsidian, '/', Item.stick, }); } } what I can write in the part: public static void init() { EspadaDeObsidiana = new ItemSword(ItemInfo.WAND_ID, (here)); appear error in that part, I think I must write EnumToolMaterial, but the recipe uses Obsidian, the obsidian is not in the type EnumToolMaterial, what can I do?

I want to create a Mod with swords, tools (picaxe, axe, shovel, hoe) and armor, but I don't know how, can you help me?

this is the class of the mod: package example; import net.minecraft.item.ItemStack; import cpw.mods.fml.common.Mod; import cpw.mods.fml.common.Mod.EventHandler; import cpw.mods.fml.common.Mod.Instance; import cpw.mods.fml.common.SidedProxy; import cpw.mods.fml.common.event.FMLInitializationEvent; import cpw.mods.fml.common.event.FMLPostInitializationEvent; import cpw.mods.fml.common.event.FMLPreInitializationEvent; import cpw.mods.fml.common.network.NetworkMod; import cpw.mods.fml.common.registry.GameRegistry; import example.config.ConfigHandler; import example.items.Items; import example.network.PacketHandler; import example.proxies.CommonProxy; @Mod(modid = ModInformation.ID, name = ModInformation.NAME, version = ModInformation.VERSION) @NetworkMod(channels = {ModInformation.CHANNEL}, clientSideRequired = true, serverSideRequired = true, packetHandler = PacketHandler.class) public class Itz { @Instance(ModInformation.ID) public static Itz instance; @SidedProxy(clientSide = "example.proxies.ClientProxy", serverSide = "example.proxies.CommonProxy") public static CommonProxy proxy; @EventHandler public void preInit(FMLPreInitializationEvent event) { ConfigHandler.init(event.getSuggestedConfigurationFile()); Items.init(); proxy.initSounds(); proxy.initRenderers(); } @EventHandler public void load(FMLInitializationEvent event) { Items.addNames(); } @EventHandler public void modsLoaded(FMLPostInitializationEvent event) { } }

I want to create a Mod with a obsidian sword, the recipe will be two of obsidian and one stick, but I don't know how to give it a recipe, this is the class of the item: package example.items; import net.minecraft.client.renderer.texture.IconRegister; import net.minecraft.creativetab.CreativeTabs; import net.minecraft.entity.EntityLivingBase; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import cpw.mods.fml.relauncher.Side; import cpw.mods.fml.relauncher.SideOnly; public class ItemWand extends Item { public ItemWand(int id) { super(9520); setCreativeTab(CreativeTabs.tabCombat); setMaxStackSize(1); setUnlocalizedName(ItemInfo.WAND_UNLOCALIZED_NAME); } public boolean func_111207_a(ItemStack itemstack, EntityPlayer player, EntityLivingBase target) { if(!target.worldObj.isRemote) { target.motionY = 2; } return false; } @Override @SideOnly(Side.CLIENT) public void registerIcons(IconRegister register) { itemIcon = register.registerIcon(ItemInfo.TEXTURE_LOCATION + ":" + ItemInfo.WAND_ICON); } how I give it a recipe? this is the class "Items" package example.items; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import cpw.mods.fml.common.registry.GameRegistry; import cpw.mods.fml.common.registry.LanguageRegistry; public class Items { public static Item EspadaDeObsidiana; public static void init() { EspadaDeObsidiana = new ItemWand(ItemInfo.WAND_ID); } public static void addNames() { LanguageRegistry.addName(EspadaDeObsidiana, ItemInfo.WAND_NAME); } public static void registerRecipes() { GameRegistry.addRecipe(new ItemStack (EspadaDeObsidiana, 1), new Object[] { " X ", " X ", " / ", 'X', "Block.BlockObsidian", '/', "Item.stick", }); } } what need the classes?

I just want to know where and how I initialize the item

you don't have the class ItemInfo? http://courses.vswe.se/?course=3 that will help you

in the class "ItemInfo" you must write: public static final String (itemname)_ICON = "name of the file"; you must place the texture of you mod in: assets."folder source".textures.items the name in the declaration and the file must be the same, example: public static final String (itemname)_ICON = Taladro; assets.Taladro.textures.items.Taladro.png

and how I do that?

can you help me? http://courses.vswe.se/?course=3&thread=302

I have a problem, in "Items.java", in this part: http://courses.vswe.se/?course=3&lecture=24&thread=301 what I do?

help with this part, clientSideRequired = true, serverSideRequiered = true if I put "true" in clientSideRequired, what happen? what happen if I put "false"? equal in the part: serverSideRequired, what happen in all the cases?

I can use any version? does not matter if I use Minecraft 1.6.4?
