I need help with a custom ranged projectile. (Solved)

[First Sliver]

I just started modding Terraria a little while ago, and I'm having trouble making my custom bow shoot a custom custom projectile. I know how to make it shoot a custom projectile, but It doesn't work if it uses ammo. I've tried looking at tutorials, but I get errors with overriding Shoot().
Here's the code for the bow:

using Terraria;
using Terraria.ModLoader;
using Terraria.GameContent.Creative;
using Terraria.ID;
using ESP.Projectiles.Weapons;

namespace ESP.Items.Weapons.Bows
{
    internal class SlimeBow : ModItem
    {

        public int baseDamage = 11;

        public override void SetStaticDefaults()
        {
            CreativeItemSacrificesCatalog.Instance.SacrificeCountNeededByItemId[Type] = 1;
            DisplayName.SetDefault("Slime Bow"); // By default, capitalization in classnames will add spaces to the display name. You can customize the display name here by uncommenting this line.
            Tooltip.SetDefault("The remains of a once powerful bow...");
        }

        public override void SetDefaults()
        {
            Item.width = 16;
            Item.height = 32;

            Item.useTime = 35;
            Item.useAnimation = 35;
            Item.useStyle = 5;

            Item.UseSound = SoundID.Item5;
            Item.autoReuse = true;

            Item.DamageType = DamageClass.Ranged;
            Item.damage = baseDamage;
            Item.knockBack = 2;

            Item.rare = ItemRarityID.Blue;
            Item.value = 50;

            Item.noUseGraphic = false;
            Item.noMelee = true;

            Item.shootSpeed = 6f;
            Item.useAmmo = AmmoID.Arrow;
            Item.shoot = ModContent.ProjectileType<SlimyArrow>();
        }

        public override void ModifyWeaponDamage(Player player, ref StatModifier damage)
        {
            Item.damage = baseDamage;
            Item.damage+= player.GetModPlayer<GlobalPlayer>().slimyDamageFlat;
            damage += player.GetModPlayer<GlobalPlayer>().slimyDamagePercent;
        }

        public override void AddRecipes()
        {
            Recipe recipe = CreateRecipe();
            recipe.AddIngredient(ItemID.Gel, 20);
            recipe.AddIngredient(ModContent.ItemType<FracturedSlimeBow>());
            recipe.AddTile(TileID.Solidifier);
            recipe.Register();
        }
    }
}

And here's the code for the projectile:

using Terraria;
using Terraria.ModLoader;
using Terraria.GameContent.Creative;
using Terraria.ID;
using ESP.Projectiles.Weapons;

namespace ESP.Projectiles.Weapons
{
    internal class SlimyArrow : ModProjectile
    {

        public int baseDamage = 4;

        public override void SetStaticDefaults()
        {
            CreativeItemSacrificesCatalog.Instance.SacrificeCountNeededByItemId[Type] = 1;
            DisplayName.SetDefault("Slimy Arrow");
        }

        public override void SetDefaults()
        {
            Projectile.DamageType = DamageClass.Ranged;
            Projectile.width = 14;
            Projectile.height = 32;
            Projectile.aiStyle = 0;
            Projectile.friendly = true;
            Projectile.hostile = false;
            Projectile.penetrate = 2;
            Projectile.timeLeft = 600;
            Projectile.light = 0f;
            Projectile.ignoreWater = false;
            Projectile.tileCollide = true;
        }
    }
}

I've tried overriding Shoot() like this:

public override bool Shoot(Player player, ref Vector2 position, ref float speedX, ref float speedY, ref int type, ref int damage, ref float knockBack)
{
   
}

but it says "type or namespace 'Vector2' could not be found."
I've also tried overriding it like this:

public override bool Shoot(Player player, EntitySource_ItemUse_WithAmmo source, Vector2 position, Vector2 velocity, int type, int damage, float knockback)
{
   
}

and it says "type or namespace 'EntitySource_ItemUse_WithAmmo' could not be found."
What is it that I'm doing wrong?

Edit:
After searching around more, I realized what the issue was. I forgot this line of code in the code for the bow:

using Microsoft.Xna.Framework;
