So I've made a few items in my mod, and I'm trying to figure out how to make an item action. My item(s) of interest are a syringe(blood and not used), and I'm wondering how you code it so that when the syringe is used, it turns into a syringe with blood. Here's my code for the item: package DrDaron5.RobotMod.items.itemclasses; import DrDaron5.RobotMod.Reference; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.potion.PotionEffect; import net.minecraft.util.ResourceLocation; import net.minecraft.world.World; public class ItemSyringe extends Item{ String type; public ItemSyringe(String unlocalizedName, String registryName){ this.setUnlocalizedName(unlocalizedName); this.setRegistryName(Reference.MODID, unlocalizedName); type = "clean"; } public ItemSyringe(String unlocalizedName, String registryName, boolean hasBlood){ this.setUnlocalizedName(unlocalizedName); this.setRegistryName(Reference.MODID, unlocalizedName); type = "blood"; } public boolean hasBlood(ItemSyringe sample){ if(sample.returnType().equals("blood")) return true; else return false; } public String returnType(){ { return type; } } } Anyone know? Thanks in advance

So I'm working on my first mod(Using online tutourial), and I'm having an issue with the setUnlocaliziedName method package DrDaron5.firstmod; import cpw.mods.fml.common.Mod; import cpw.mods.fml.common.Mod.EventHandler; 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.registry.GameRegistry; import net.minecraft.item.Item; @Mod(modid = "fm", name = "First Mod", version = "1.0") public class firstmod { public static Item itemRobot; @EventHandler public void preInit(FMLPreInitializationEvent event){ // Registration of Items/Handeling Config itemRobot = new ItemRobot().setUnlocalizedName("ItemRobot"); GameRegistry.registerItem(itemRobot, itemRobot.getUnlocalizedName().substring(5)); } @EventHandler public void init(FMLInitializationEvent event) { // GUI, Enity, Proxy,and Entity } @EventHandler public void postInit(FMLPostInitializationEvent event){ } } The Error says the following: The method setUnlocalizedName(String) is undefined for the type ItemRobot firstmod.java /Minecraft/src/main/java/DrDaron5/firstmod line 18 Java Problem Can someone tell what I'm doing wrong?
