            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;
        }
    }
}

What does this mean and how can I fix it?

Feralkitty9 · Oct 28, 2020

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 code:

{
public class CursedIce : ModProjectile
{
public override void SetDefaults()
{
projectile.name = "Cursed Ice";

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.
