Check the code for the Bow and Arrow, it should be very similar to what you want to do.

if you mean the item to don't be consumed or damaged, the code is in Item.onItemRightClick

else if you mean the entity to don't being destroyed on impact the code is in EntitySnowball.onImpact

How do I do that?
Here's my code:

package com.spyeedy.itemsplus.classes.ironman;

import com.spyeedy.itemsplus.HeroesPlus;
import com.spyeedy.itemsplus.items.Ironman;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.IProjectile;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.projectile.EntitySnowball;
import net.minecraft.init.Items;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.stats.StatList;
import net.minecraft.world.World;

public class ItemRepulsor extends Item {
	
	public ItemRepulsor(String unlocalizedName)
    {
        this.maxStackSize = 64;
        this.setUnlocalizedName(unlocalizedName);
        this.setCreativeTab(HeroesPlus.tabIronmanPlus);
    }

    /**
     * Called whenever this item is equipped and the right mouse button is pressed. Args: itemStack, world, entityPlayer
     */
	public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn)
    {
        if (!playerIn.capabilities.isCreativeMode)
        {
            --itemStackIn.stackSize;
        }

        worldIn.playSoundAtEntity(playerIn, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!worldIn.isRemote)
        {
            worldIn.spawnEntityInWorld(new EntityRepulsorBolt(worldIn, playerIn));
        }

        playerIn.triggerAchievement(StatList.objectUseStats[Item.getIdFromItem(this)]);
        return itemStackIn;
    }
}

I hope I'm not bumping the thread. :mellow:

this code decrease the itemstack size:

if (!playerIn.capabilities.isCreativeMode) { --itemStackIn.stackSize; }

remove it and your itemstack will not decrease

That worked! Thanks, how do I shoot a projectile like the bow does with the arrows. But I don't want 3 (or is it 4?) animations, just a blast to shoot like the snowball one. Sorry if I confused whoever can help.

It doesn't shoot an EntityRepulsorBolt projectile like the snowball does, but the explosion occurs.
Here's my item code:

package com.spyeedy.heroesplus.classes.ironman;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.stats.StatList;
import net.minecraft.world.World;

import com.spyeedy.heroesplus.HeroesPlus;

public class ItemRepulsor extends Item {
	
	public ItemRepulsor(String unlocalizedName)
    {
        this.maxStackSize = 1;
        this.setUnlocalizedName(unlocalizedName);
        this.setCreativeTab(HeroesPlus.tabIronmanPlus);
    }

    /**
     * Called whenever this item is equipped and the right mouse button is pressed. Args: itemStack, world, entityPlayer
     */
	public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn)
    {

        worldIn.playSoundAtEntity(playerIn, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!worldIn.isRemote)
        {
            worldIn.spawnEntityInWorld(new EntityRepulsorBolt(worldIn, playerIn));
        }

        playerIn.triggerAchievement(StatList.objectUseStats[Item.getIdFromItem(this)]);
        return itemStackIn;
    }
}

And the Entity code:

package com.spyeedy.heroesplus.classes.ironman;

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.registry.IThrowableEntity;

public class EntityRepulsorBolt extends EntityThrowable {

	public double explosionRadius = 1.0F;

	public EntityRepulsorBolt(World worldIn) {
		super(worldIn);
	}
	
	public EntityRepulsorBolt(World worldIn, double x, double y, double p_i1778_6_) {
		super(worldIn, x, y, p_i1778_6_);
	}
	
	public EntityRepulsorBolt(World worldIn, EntityLivingBase throwerIn) {
		super(worldIn, throwerIn);
	}
	
	@Override
	protected void onImpact(MovingObjectPosition MovingObjectPosition) {
		this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, (float)this.explosionRadius, true);
		this.setDead();
	}
}

Is there anything I'm missing in my code?

I need to render my projectile? Using rendringregistry? Render it like the arrow?

Here's the rendering for one of my custom arrow:

package com.spyeedy.heroesplus.classes.lanterns.hope;

import net.minecraft.client.renderer.entity.RenderArrow;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.entity.Entity;
import net.minecraft.util.ResourceLocation;

public class RenderHopeArrow extends RenderArrow {
	
	private static final ResourceLocation hopearrowTexture = new ResourceLocation("psm:textures/items/bluelantern/entity_hope_arrow.png");

	public RenderHopeArrow(RenderManager renderManager) {
		super(renderManager);
	}
	
	@Override
	public ResourceLocation getEntityTexture(Entity p_180550_1_) {
		return hopearrowTexture;
	}
}

Do I follow the same thing as how the arrow is rendered except I extend RenderSnowball instead?

if you want it to look like an arrow, follow the arrow's rendering class, otherwise follow the snowball rendering class or fireball

I followed the snowball rendering, and now I'm stuck at rendering registry. I will show you the code. It's easier to see than explain(it's hard to).

Rendering repulsor:

package com.spyeedy.heroesplus.classes.ironman;

import net.minecraft.client.renderer.entity.Render;
import net.minecraft.client.renderer.entity.RenderItem;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.client.renderer.entity.RenderSnowball;
import net.minecraft.entity.Entity;
import net.minecraft.item.Item;
import net.minecraft.util.ResourceLocation;

public class RenderRepulsorBolt extends RenderSnowball {
	
	public static final ResourceLocation repulsortexture = new ResourceLocation("psm:textures/items/ironman/items/repulsor.png");

	public RenderRepulsorBolt(RenderManager p_i46137_1_, Item p_i46137_2_, RenderItem p_i46137_3_) {
		super(p_i46137_1_, p_i46137_2_, p_i46137_3_);
	}

	@Override
	public ResourceLocation getEntityTexture(Entity entity) {
		return null;
	}

}

RenderingRegistry:

RenderingRegistry.registerEntityRenderingHandler(EntityRepulsorBolt.class, new RenderRepulsorBolt(Minecraft.getMinecraft().getRenderManager(), null, null));

What do I need to fill in place of the 2 nulls in rendering registry? I let Eclipse implement the method for me in my rendering repulsor's class. I've no idea what those values do.

Edit #1: I changed those 3 values to renderManager, item and renderItem, in the respective order.

But what do I have to type for the 2 nulls?

It's finally shooting a projectile, but instead of my own texture, it fires a white block.

I registered the entity and item of the projectile, I still can't figure out what I should replace the 2 nulls with.

What do you want your projectile to spawn from? From a gun sort of or like ironman's repulsor which I'm doing?

You need to register your entity and item. For me, I registered my entity in a single class where I register any entities I might/will create in the future along with renderingregistry.

My item repulsor class:

package com.spyeedy.heroesplus.classes.ironman;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.stats.StatList;
import net.minecraft.world.World;

import com.spyeedy.heroesplus.HeroesPlus;

public class ItemRepulsor extends Item {
	
	public ItemRepulsor(String unlocalizedName)
    {
        this.maxStackSize = 1;
        this.setUnlocalizedName(unlocalizedName);
        this.setCreativeTab(HeroesPlus.tabIronmanPlus);
    }

    /**
     * Called whenever this item is equipped and the right mouse button is pressed. Args: itemStack, world, entityPlayer
     */
	public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn)
    {

        worldIn.playSoundAtEntity(playerIn, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!worldIn.isRemote)
        {
            worldIn.spawnEntityInWorld(new EntityRepulsorBolt(worldIn, playerIn));
        }

        playerIn.triggerAchievement(StatList.objectUseStats[Item.getIdFromItem(this)]);
        return itemStackIn;
    }
}

EntityRepulsor class:

package com.spyeedy.heroesplus.classes.ironman;

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.IProjectile;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.registry.IThrowableEntity;

public class EntityRepulsorBolt extends EntityThrowable implements IProjectile {

 public double explosionRadius = 1.0F;

 public EntityRepulsorBolt(World worldIn) {
 super(worldIn);
 };
 
 public EntityRepulsorBolt(World worldIn, double x, double y, double p_i1778_6_) {
 super(worldIn, x, y, p_i1778_6_);
 }
 
 public EntityRepulsorBolt(World worldIn, EntityLivingBase throwerIn) {
 super(worldIn, throwerIn);
 }
 
 @Override
 protected void onImpact(MovingObjectPosition MovingObjectPosition) {
 this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, (float)this.explosionRadius, true);
 this.setDead();
 }
}

My entity registry:

package com.spyeedy.heroesplus;

import net.minecraft.client.Minecraft;
import net.minecraft.item.Item;
import net.minecraftforge.fml.client.registry.RenderingRegistry;
import net.minecraftforge.fml.common.registry.EntityRegistry;
import net.minecraftforge.fml.common.registry.GameRegistry;

import com.spyeedy.heroesplus.classes.ironman.EntityRepulsorBolt;
import com.spyeedy.heroesplus.classes.ironman.ItemRepulsor;
import com.spyeedy.heroesplus.classes.ironman.RenderRepulsorBolt;
import com.spyeedy.heroesplus.classes.lanterns.fear.EntityFearArrow;
import com.spyeedy.heroesplus.classes.lanterns.fear.RenderFearArrow;
import com.spyeedy.heroesplus.classes.lanterns.hope.EntityHopeArrow;
import com.spyeedy.heroesplus.classes.lanterns.hope.RenderHopeArrow;
import com.spyeedy.heroesplus.classes.lanterns.rage.EntityRageArrow;
import com.spyeedy.heroesplus.classes.lanterns.rage.RenderRageArrow;
import com.spyeedy.heroesplus.classes.lanterns.will.EntityWillArrow;
import com.spyeedy.heroesplus.classes.lanterns.will.RenderWillArrow;
import com.spyeedy.heroesplus.items.Ironman;

public class CustomEntities {

	private static int id = 0;

	public static String repulsor;
	public static String WillArrow;
	public static String FearArrow;
	public static String RageArrow;
	
	public static void init() {
		System.out.println("calling #init");
	}
	
	public static void register() {
		System.out.println("calling #register");
		EntityRegistry.registerModEntity(EntityWillArrow.class, "will_arrow", id++, HeroesPlus.instance, 64, 20, false);
		EntityRegistry.registerModEntity(EntityFearArrow.class, "fear_arrow", id++, HeroesPlus.instance, 64, 20, false);
		EntityRegistry.registerModEntity(EntityRageArrow.class, "rage_arrow", id++, HeroesPlus.instance, 64, 20, false);
		EntityRegistry.registerModEntity(EntityHopeArrow.class, "hope_arrow", id++, HeroesPlus.instance, 64, 20, false);
		EntityRegistry.registerModEntity(EntityRepulsorBolt.class, "repulsor", id++, HeroesPlus.instance, 64, 10, true);
	}
	
	public static void registerRenders()
	{
		System.out.println("calling #registerRenders");
		RenderingRegistry.registerEntityRenderingHandler(EntityWillArrow.class, new RenderWillArrow(Minecraft.getMinecraft().getRenderManager()));
		RenderingRegistry.registerEntityRenderingHandler(EntityFearArrow.class, new RenderFearArrow(Minecraft.getMinecraft().getRenderManager()));
		RenderingRegistry.registerEntityRenderingHandler(EntityRageArrow.class, new RenderRageArrow(Minecraft.getMinecraft().getRenderManager()));
		RenderingRegistry.registerEntityRenderingHandler(EntityHopeArrow.class, new RenderHopeArrow(Minecraft.getMinecraft().getRenderManager()));
	}
}

One problem though, my projectile shoots a white block instead of my item. Can't seem to fix it.

Edit #1: I've yet to add the renderingregistry as I can't figure out which nulls I should replace with.

RenderingRegistry.registerEntityRenderingHandler(EntityRepulsorBolt.class, new RenderRepulsorBolt(Minecraft.getMinecraft().getRenderManager(), null, null));

RenderRepulsor class:

package com.spyeedy.heroesplus.classes.ironman;

import net.minecraft.client.renderer.entity.Render;
import net.minecraft.client.renderer.entity.RenderItem;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.client.renderer.entity.RenderSnowball;
import net.minecraft.entity.Entity;
import net.minecraft.item.Item;
import net.minecraft.util.ResourceLocation;

public class RenderRepulsorBolt extends RenderSnowball {
	
	public static final ResourceLocation repulsortexture = new ResourceLocation("psm:textures/items/ironman/items/repulsor.png");
	
	public RenderRepulsorBolt(RenderManager renderManager, Item item, RenderItem renderItem) {
		super(renderManager, item, renderItem);
	}

	@Override
	public ResourceLocation getEntityTexture(Entity entity) {
		return repulsortexture;
	}

}
