[1.12.2] Is item dropped in world

[LazyTechwork]

Hello! I have onUpdate method

onUpdate(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected)

I need to check - is item in world as dropped item, after that I need to change item to another. How can I do this?

For simple tasks you can override Item#onEntityItemUpdate. Or you can provide a completely custom item entity by overriding Item#hasCustomEntity and Item#createEntity.

So, after that I spawn new entityitem:

@Override
public boolean onEntityItemUpdate(EntityItem entityItem) {
    World world = entityItem.world;
    if (world.isRemote) {
        world.createExplosion(entityItem, entityItem.posX, entityItem.posY, entityItem.posZ, 0f, true);
        world.removeEntity(entityItem);
        world.spawnEntity(new EntityItem(world, entityItem.posX, entityItem.posY, entityItem.posZ, new ItemStack(ItemsRegistry.URANIUM, 1)));
    }
    return super.onEntityItemUpdate(entityItem);
}

But, I can't pickup new EntityItem. How can I fix this?

By checking if the world is remote, you are only executing the if statement on the client side.

You probably meant to inverse this.
