I got it.

It looks way better. Thanks for the advice. @Override public boolean canApplyAtEnchantingTable(ItemStack stack, Enchantment enchantment) { Set e = ImmutableSet.of( Enchantments.SHARPNESS, Enchantments.LOOTING, Enchantments.FIRE_ASPECT, Enchantments.UNBREAKING, Enchantments.KNOCKBACK ); return e.contains(enchantment); }

@Override public boolean canApplyAtEnchantingTable(ItemStack stack, Enchantment enchantment) { Enchantment[] enchantments = { Enchantments.SHARPNESS, Enchantments.LOOTING, Enchantments.FIRE_ASPECT, Enchantments.UNBREAKING, Enchantments.KNOCKBACK, Enchantments.MENDING, }; for(int i=0;i<enchantments.length;i++){ if(enchantments[i] == enchantment){ return true; } } return false; } I wrote this and it worked. Thx.

@Override public boolean canApplyAtEnchantingTable(ItemStack stack, Enchantment enchantment) { if(enchantment == Enchantments.SHARPNESS) { enchantment.canApply(stack); } return true; } I changed with this but same error.

@Override public boolean canApplyAtEnchantingTable(ItemStack stack, Enchantment enchantment) { enchantment = Enchantments.SHARPNESS; return enchantment.canApply(stack.getItem().getDefaultInstance()); } I tried to override this method. Whenever i put the item in the enchantment table game crashes with java.lang.StackOverflowError.

I created a custom item that extends TieredItem. I want it to be enchantable through the enchantment table with Sharpnes, Looting etc. I can enchant but only the unbreaking enchantment shows up.

Finally i fixed the all problems. I added this condition and thats all. world.chunkExists(specialItemEntity.chunkCoordX,specialItemEntity.chunkCoordZ) Final code is : EventHandler class package com.azizd.thunderbird.events; import com.azizd.thunderbird.Thunderbird; import com.azizd.thunderbird.entities.SpecialItemEntity; import com.azizd.thunderbird.init.itemInit; import net.minecraft.entity.Entity; import net.minecraft.entity.item.ItemEntity; import net.minecraft.item.ItemStack; import net.minecraft.world.World; import net.minecraftforge.event.entity.EntityJoinWorldEvent; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.fml.common.Mod; @Mod.EventBusSubscriber(modid = Thunderbird.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE) public class EventHandler { public static void register(){} @SubscribeEvent public static void crimsonIngotCraft(EntityJoinWorldEvent event){ Entity entity = event.getEntity(); World world = entity.world; double posX = entity.getPosX(); double posY = entity.getPosY(); double posZ = entity.getPosZ(); SpecialItemEntity specialItemEntity = new SpecialItemEntity(world, posX, posY, posZ); if(entity instanceof ItemEntity && !(entity instanceof SpecialItemEntity)){ ItemEntity itemEntity = (ItemEntity) event.getEntity(); ItemStack item = itemEntity.getItem(); if(item.getItem() == itemInit.RED_PEARL.get()){ if(world.chunkExists(specialItemEntity.chunkCoordX,specialItemEntity.chunkCoordZ)) { event.setCanceled(true); specialItemEntity.setItem(itemEntity.getItem().getStack()); specialItemEntity.setPickupDelay(30); specialItemEntity.setMotion(itemEntity.getMotion()); world.addEntity(specialItemEntity); } } } } } SpecialItemEntity class package com.azizd.thunderbird.entities; import com.azizd.thunderbird.init.itemInit; import net.minecraft.entity.item.ItemEntity; import net.minecraft.item.ItemStack; import net.minecraft.world.World; public class SpecialItemEntity extends ItemEntity { private ItemEntity entity = new ItemEntity(this.world,this.getPosX(),this.getPosY(),this.getPosZ()); public SpecialItemEntity(World worldIn, double x, double y, double z) { super(worldIn, x, y, z); } @Override public void tick() { if(this.inWater && !this.world.isRemote){ this.setDead(); int count = this.getItem().getCount(); entity.setPosition(this.getPosX(),this.getPosY(),this.getPosZ()); entity.setItem(new ItemStack(itemInit.CRIMSON_INGOT.get())); entity.getItem().setCount(count); this.world.addEntity(entity); } else{ super.tick(); } } }

This is not the issue.

But i still have a bug. If specialItemEntity is in the world. I can't join that world.

Finally i fixed all the problems. Now it works exactly what i want. This is my EventHandler Method @SubscribeEvent public static void crimsonIngotCraft(EntityJoinWorldEvent event){ Entity entity = event.getEntity(); World world = entity.world; double posX = entity.getPosX(); double posY = entity.getPosY(); double posZ = entity.getPosZ(); if(entity instanceof ItemEntity && !(entity instanceof SpecialItemEntity)){ ItemEntity itemEntity = (ItemEntity) event.getEntity(); if(itemEntity.getItem().getItem() == itemInit.RED_PEARL.get()){ event.setCanceled(true); SpecialItemEntity specialItemEntity = new SpecialItemEntity(world,posX,posY,posZ); specialItemEntity.setItem(itemEntity.getItem().getStack()); specialItemEntity.setPickupDelay(50); specialItemEntity.setMotion(itemEntity.getMotion()); world.addEntity(specialItemEntity); } } } And this is my SpecialItemEntity class package com.azizd.thunderbird.entities; import com.azizd.thunderbird.init.itemInit; import net.minecraft.entity.item.ItemEntity; import net.minecraft.item.ItemStack; import net.minecraft.world.World; import net.minecraftforge.common.extensions.IForgeEntity; public class SpecialItemEntity extends ItemEntity implements IForgeEntity { public SpecialItemEntity(World worldIn, double x, double y, double z) { super(worldIn, x, y, z); } ItemEntity entity = new ItemEntity(getEntityWorld(),this.getPosX(),this.getPosY(),this.getPosZ()); @Override public void tick() { if(this.inWater){ this.setDead(); int count = this.getItem().getCount(); entity.setPosition(this.getPosX(),this.getPosY(),this.getPosZ()); entity.setItem(new ItemStack(itemInit.CRIMSON_INGOT.get())); entity.getItem().setCount(count); this.world.addEntity(entity); } else{ super.tick(); } } } Thanks for the helps.

I solved the pickup bug. The only problem is SpecialItemEntity motion.

I am settting the pickup delay to default every tick. This is why i cant pick up the item. The motion part is incomplete so item drop part is bad.

It is kinda working right now. This is EventHandler part public static void crimsonIngotCraft(EntityJoinWorldEvent event){ Entity entity = event.getEntity(); World world = entity.world; double posX = entity.getPosX(); double posY = entity.getPosY(); double posZ = entity.getPosZ(); if(entity instanceof ItemEntity && !(entity instanceof SpecialItemEntity)){ ItemEntity itemEntity = (ItemEntity) event.getEntity(); if(itemEntity.getItem().getItem() == itemInit.RED_PEARL.get()){ event.setCanceled(true); SpecialItemEntity specialItemEntity = new SpecialItemEntity(world,posX,posY,posZ); specialItemEntity.setItem(itemEntity.getItem()); world.addEntity(specialItemEntity); } } } and this is the special item entity class package com.azizd.thunderbird.entities; import com.azizd.thunderbird.init.itemInit; import net.minecraft.entity.item.ItemEntity; import net.minecraft.item.ItemStack; import net.minecraft.world.World; import net.minecraftforge.common.extensions.IForgeEntity; public class SpecialItemEntity extends ItemEntity implements IForgeEntity { public SpecialItemEntity(World worldIn, double x, double y, double z) { super(worldIn, x, y, z); } @Override public void tick() { ItemEntity entity = new ItemEntity(getEntityWorld(),this.getPosX(),this.getPosY(),this.getPosZ()); if(this.inWater){ this.setDead(); entity.setItem(new ItemStack(itemInit.CRIMSON_INGOT.get())); this.world.addEntity(entity); } ItemStack stack = this.getItem(); if (stack != null && stack.getItem() != null && stack.getItem().onEntityItemUpdate(this.getItem(),entity)) return; if(entity == null) this.setDead(); else{ super.tick(); this.setDefaultPickupDelay(); this.prevPosX = this.getPosX(); this.prevPosY = this.getPosY(); this.prevPosZ = this.getPosZ(); this.setMotion(0,-0.098,0); } } } The item converting part is complete but i can't pickup the item i threw and motion part is bad. When i throw a whole stack it gives 1 single item rather than giving a stack.

@SubscribeEvent public static void crimsonIngotCraft(EntityJoinWorldEvent event){ Entity entity = event.getEntity(); World world = entity.world; double posX = entity.getPosX(); double posY = entity.getPosY(); double posZ = entity.getPosZ(); if(entity instanceof ItemEntity && !(entity instanceof SpecialItemEntity)){ ItemEntity itemEntity = (ItemEntity) event.getEntity(); if(itemEntity.getItem().getItem() == itemInit.RED_PEARL.get()){ SpecialItemEntity ie = new SpecialItemEntity(entity.world,entity.getPosX(),entity.getPosY(),entity.getPosZ(),((ItemEntity) entity).getItem()); event.setCanceled(true); SpecialItemEntity specialItemEntity = new SpecialItemEntity(world,posX,posY,posZ,((ItemEntity) entity).getItem().getStack()); } } } I changed code into this and SpecialItemEntity clas is: package com.azizd.thunderbird.entities; import com.azizd.thunderbird.init.blockInit; import net.minecraft.entity.item.ItemEntity; import net.minecraft.item.ItemStack; import net.minecraft.util.math.BlockPos; import net.minecraft.world.World; public class SpecialItemEntity extends ItemEntity { public SpecialItemEntity(World worldIn, double x, double y, double z, ItemStack stack) { super(worldIn, x, y, z, stack); } @Override public void tick() { BlockPos pos= new BlockPos(getPosX(),getPosY(),getPosZ()); if(inWater){ this.setDead(); this.world.setBlockState(pos,blockInit.BLOCK_OF_RED_PEARL.get().getDefaultState()); } } } The item deletes when i press the q button.

@SubscribeEvent public static void crimsonIngotCraft(EntityJoinWorldEvent event){ Entity entity = event.getEntity(); if(entity instanceof ItemEntity){ ItemEntity itemEntity = (ItemEntity) event.getEntity(); if(itemEntity.getItem().getItem() == itemInit.RED_PEARL.get()){ System.out.println("Working!!"); if(itemEntity.isInWater()){ System.out.println("Not working :("); itemEntity.remove(); //FIXME Continue. } } } } Everything is working except the if(itemEntity.isInWater()){ System.out.println("Not working :("); itemEntity.remove(); } this part. I wanna create a recipe that you throw an item into water and water transforms into another block.
