We’ve already made a Corn item for our crop, however, we were unable to eat the corn (defeating its very purpose). Let’s make our Corn behave as actual food.

First we’ll need to create an ItemCorn class that will be our new corn item, instead of just using ItemOre. Our class will extend ItemFood so it inherits all of the vanilla food-handling logic. We’ll also want our class to have registerItemModel and initOreDict methods so it retains the functionality from the existing corn item.

The ItemFood constructor takes 3 parameters:

1. The amount of hunger restored by this food.
2. The saturation given by this food.
3. If this food is edible by wolves.

We’ll pass in 3, 0.6f, and false for the hunger, saturation, and wolf food values, the same values as the Carrot. Also in the constructor, we’ll call setUnlocalizedName and setRegistryName with the same value as we used for the original corn item (corn). We’ll also call setCreativeTab with our custom creative tab.

We’ll also need to implement the registerItemModel and initOreDict methods.

In registerItemModel, we’ll use our proxy registerItemRenderer method to register an item model for our corn item. We’ll use corn as the model name, the same as our original item.

We’ll also implement initOreDict and call the OreDictionary.registerOre method with cropCorn as the ore name, the same as our original item.

package net.shadowfacts.tutorial.item;

import net.minecraft.item.Item;
import net.minecraft.item.ItemFood;
import net.minecraftforge.oredict.OreDictionary;
import net.shadowfacts.tutorial.TutorialMod;

public class ItemCorn extends ItemFood {

	public ItemCorn() {
		super(3, 0.6f, false);
		setUnlocalizedName("corn");
		setRegistryName("corn");
		setCreativeTab(TutorialMod.creativeTab);
	}
	
	public void registerItemModel(Item item) {
		TutorialMod.proxy.registerItemRenderer(this, 0, "corn");
	}
	
	public void initOreDict() {
		OreDictionary.registerOre("cropCorn", this);
	}

}

In the ModItems class, we’ll also need to change the corn field.

// ...
public class ModItems {
	// ...
	public static ItemCorn corn = new ItemCorn();
	// ...
}

We simply need to change the corn field to by of item ItemCorn and the registration call to instantiate ItemCorn instead of ItemOre.

Now we’ve got an edible corn item!
