How do i make my weapons shoot projectiles?

C#: 
using System;
using Microsoft.Xna.Framework;
using Terraria;
using Terraria.Graphics.Effects;
using Terraria.Graphics.Shaders;
using Terraria.ID;
using Terraria.ModLoader;

namespace DodgeMod.Items.Weapons
{
    public class ChewToy : ModItem
    {
        public override void SetDefaults()
        {
            item.name = "Chew Toy";
            item.damage = 9750;
            item.melee = true;
            item.width = 49;
            item.height = 50;
            item.toolTip = "Woof";
            item.useTime = 8;
            item.useAnimation = 8;
            item.useStyle = 1;
            item.knockBack = 17.5;
            item.value = item.buyPrice(50, 0, 0, 0);
            item.rare = 13;
            item.useSound = 1;
            item.autoReuse = true;
            item.useTurn = true;
            item.shoot = mod.ProjectileType("Doge");
            item.shootSpeed = 8f;
        }
        public override void AddRecipes()
        {
            ModRecipe recipe = new ModRecipe(mod);
            recipe.AddIngredient(ItemID.TerraBlade, 1);
            recipe.AddIngredient(ItemID.DirtBlock, 10);
            recipe.AddTile(TileID.Workbenches);
            recipe.SetResult(this);
            recipe.AddRecipe();
            
        }
    }
}
Here is the code for my weapon, which I'm planning to make fire a pixelated Doge when I attack. Terraria states there are a few errors in this code and my projectile code. Any suggestions?

Here is my projectile code:
C#: 
using System;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Terraria;
using Terraria.ID;
using Terraria.ModLoader;

namespace DodgeMod.Items.Projectiles
{
    public class PixelatedDoge : ModProjectile
    {
        public override void SetDefaults()
        {
            
            projectile.name = "Pixelated Doge";
            projectile.width = 49;
            projectile.height = 50;
            projectile.friendly = true;
            projectile.melee = true;
            projectile.tileCollide = false;
            projectile.penetrate = 30;
            projectile.timeLeft = 500;
            projectile.light = 2.75f;
            projectile.extraUpdates = 1;
            projectile.ignoreWater = true;
        }
        public override void AI()
        {
            projectile.rotation = (float)Math.Atan2((double)projectile.velocity.Y, (double)projectile.velocity.X) + 1.57f;
        }
    }
}
 
I forgot to mention, all the code and images are in their designated folder
 
im still reading this in 2020 yet its not working
 
Here is the existing code for my sword:

            Tooltip.SetDefault("Invalid ID, please terminate to continue");
        }

        public override void SetDefaults()
        {
            item.damage = 9999;
            item.melee = true;

What does this mean and how can I fix it?
 
um.... this is a long time ago and i am WELL AWARE that coding has changed especially for terraria, but do any of you guys know the code for "shoot mod projectiles" because i did this and it says it cannot find the swords projectile, even though it is in the projectiles folder.

did you add, using servers; to the very top of the code, this might help, yet you might run into my problem

projectile.name is no longer a thing in tModLoader, so remove it. Instead add:
C#: 
public override void SetStaticDefaults()
{
    DisplayName.SetDefault("Cursed Ice");
}
Or you could just leave it blank and tModLoader will automatically assign the projectile a name based on the class name.
