How to get looting table and generate an itemstack from it? I want to make my own way to fish, but I have no idea about getting loots. Please excuse my spelling errors.

First, please excuse my spelling errors. I need to get the list of the entities that can summon by the commands. I've tried EntityList#getEntityNameList and EntityList#getClass , but as I'm using this, game crashed because of the Entity that spawned. Please tell me how to do, thanks. package task.heartstone.register; import java.util.ArrayList; import java.util.List; import java.util.Random; import java.util.Set; import org.apache.logging.log4j.LogManager; import net.minecraft.entity.Entity; import net.minecraft.entity.EntityList; import net.minecraft.entity.passive.EntityPig; import net.minecraft.util.ResourceLocation; import net.minecraft.world.World; public class EntityUtil { public static final List<Class<? extends Entity>> list = new ArrayList<Class<? extends Entity>>(); public static void load() { Set<ResourceLocation> namelist = EntityList.getEntityNameList(); for(ResourceLocation name : namelist) { Class<? extends Entity> clazz = EntityList.getClass(name); if(clazz != null) { list.add(clazz); } } for(Class clazz : list) { LogManager.getLogger("EntityUtil").info(clazz.getName()); } } public static Entity getRandEntity(World world) { Random rand = new Random(); int index = rand.nextInt(list.size()-1); return EntityList.newEntity(list.get(index), world); } }

Thank you very much!!!

Is that can change by anvil? I need the vanilla name...

I tried getUnlocalizedName() + ".name", but if the item has metadata like dye, it doesn't work. What can I do?

Thanks!

How to get drop item of a destroyed block? (My English is not good at all. So...)

Code: @Override public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) { if(!worldIn.isRemote) { ItemStack itemstack = playerIn.getHeldItem(handIn); NBTTagCompound nbt = itemstack.getTagCompound(); int blood = nbt.hasKey("blood") ? nbt.getInteger("blood") : 0; if(playerIn.isSneaking()) { blood += 2; playerIn.attackEntityFrom(BloodLose, 2.0f); } else { blood -= 5; playerIn.setHealth(playerIn.getHealth() + 5.0f); } nbt.setInteger("blood", blood); } return super.onItemRightClick(worldIn, playerIn, handIn); } Console: Caused by: java.lang.NullPointerException at TCr.Dark.items.tools.SwordDark.onItemRightClick(SwordDark.java:34) ~[SwordDark.class:?] at net.minecraft.item.ItemStack.useItemRightClick(ItemStack.java:234) ~[ItemStack.class:?] at net.minecraft.server.management.PlayerInteractionManager.processRightClick(PlayerInteractionManager.java:384) ~[PlayerInteractionManager.class:?] at net.minecraft.network.NetHandlerPlayServer.processTryUseItem(NetHandlerPlayServer.java:794) ~[NetHandlerPlayServer.class:?] at net.minecraft.network.play.client.CPacketPlayerTryUseItem.processPacket(CPacketPlayerTryUseItem.java:43) ~[CPacketPlayerTryUseItem.class:?] at net.minecraft.network.play.client.CPacketPlayerTryUseItem.processPacket(CPacketPlayerTryUseItem.java:9) ~[CPacketPlayerTryUseItem.class:?] at net.minecraft.network.PacketThreadUtil$1.run(PacketThreadUtil.java:21) ~[PacketThreadUtil$1.class:?] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) ~[?:1.8.0_151] at java.util.concurrent.FutureTask.run(Unknown Source) ~[?:1.8.0_151] at net.minecraft.util.Util.runTask(Util.java:53) ~[Util.class:?] ... 5 more

I know that is basic java, but I just know a little about Map, so... But thanks!

Thanks!

Thanks, but how can I turn this Map into int array.

Integer[] dimensions = DimensionManager.getStaticDimensionIDs();

It didn't crash, just throw this.

I wanna get a list of dimensions. So I tried DimensionManager.getStaticDimensionIDs(), but it doesn't work. It throws "java.lang.NullPointerException" And I tried another way that from diesieben07，but it still can't work and my eclipse tell me that "Type mismatch: cannot convert from IntStream to int[]".
