How would I go about transforming the character into another sprite for a duration, example: turning the player into a squirrel

Oh no I did a mistake! Sorry.
I must've been really sleepy and ignored the facts.
There might be an easier way but for right now it's gonna be more complicated.

C#:

using Terraria;
using Terraria.ID;
using Terraria.ModLoader;
using static Terraria.ModLoader.ModContent;

namespace Mod.Items.Armor
{
    [AutoloadEquip(EquipType.Head)]
    public class ModArmor : ModItem // Change ModArmor to the name you want.
    {

        public bool ArmorOn; // You can change the name if you want.

        public override void SetDefaults() {
            item.width = Width; // replace with width
            item.height = Height; // replace with height
            item.value = Value; // replace with value
            item.rare = Rarity; // replace with rarity
            item.defense = Defense; // replace with defense
        }

        public override void UpdateArmorSet(Player player) {
            ArmorOn = true;
        }
    }
}

Here is the second piece of code.

C#:

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.IO;
using Terraria.ModLoader.IO;
using Terraria.Utilities;
using Mod.Items.Armor;

namespace Mod.Items
{
    public class Item : GlobalItem
    {
        public virtual void OnHitNPC(Item item, Player player, NPC target, int damage, float knockBack, bool crit)
        {
            if (ModArmor.ArmorOn == true) {
                player.AddBuff(58, 2);
            }
        }
    }
}

I hope what I'm doing is correct. If it's not, then sorry.

Im getting an error and i dont know if i did something wrong or if theres an error in your code but i got an error "error CS0120 An object reference is required for the non-static field, method, or property 'PalladiumCrown.RegenCrown'"
here is the code plz tell me if you know how to fix it, because i dont

C#:

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.IO;
using Terraria.ModLoader.IO;
using Terraria.Utilities;
using Terraria;
using Terraria.ID;
using Terraria.ModLoader;
using ThrowingRevived.Items.Equipable.OreHelmets;

namespace ThrowingRevived.Items.Equipable.OreHelmets
{
    public class RegenCrown : GlobalItem
    {
        public virtual void OnHitNPC(Item item, Player player, NPC target, int damage, float knockBack, bool crit)
        {
            if (PalladiumCrown.RegenCrown == true) { // this is where it says the error is.
                player.AddBuff(58, 2);
            }
        }
    }
}

and just in case i did something wrong in the other part ill put it here too

C#:

using Terraria;
using Terraria.ModLoader;
using static Terraria.ModLoader.ModContent;
using Terraria.ID;

namespace ThrowingRevived.Items.Equipable.OreHelmets
{
    [AutoloadEquip(EquipType.Head)]
    public class PalladiumCrown : ModItem
    {
        public bool RegenCrown;
        
        public override void SetDefaults() {
            item.width = 18;
            item.height = 18;
            item.value = 10000;
            item.rare = ItemRarityID.LightRed;
            item.defense = 7;
        }
        
        public override void UpdateEquip(Player player) {
            player.thrownDamage += 0.14f;
        }

        public override bool IsArmorSet(Item head, Item body, Item legs) {
            return body.type == ItemID.PalladiumBreastplate && legs.type == ItemID.PalladiumLeggings;
        }

        public override void UpdateArmorSet(Player player) {
            player.setBonus = "Greatly increases life regeneration after striking an enemy";
            RegenCrown = true;
        }
    }
}

You just need this:

C#:

public override void UpdateArmorSet(Player player) {
    // your other codes here
    player.palladiumRegen = true;
}

Then vanilla Terraria will do the rest.

C#:

if (downedBoss2 == true) { }

You have to write NPC. in from of the downedBoss2. And you don't need "== true".

C#:

if(NPC.downedBoss2){
    // do your thing
}

My question : Is it a good idea to cache item/buff/projectile etc IDs? Of course I would reset/set them as my mod unloads/loads.

C#:

using static Terraria.ModLoader.ModContent;

public class IDs{
    public class Item{
        // some static fields that hold itemtype values
        public static int TestItem;
    }
    public class Buff{
        // same here
        public static int TestBuff;
    }
    internal static Initialize(){
        // I would use ModContent.ItemType<T>() etc to set the values of the fields
        Item.TestItem = ItemType<TestItem>();
        Buff.TestBuff = BuffType<TestBuff>();
    }
}

Something like this.

You just need this:

Then vanilla Terraria will do the rest.

well, that doesnt work either, instead of getting the regen after striking an enemy, you have it when you dont have max health, not quite how palladium armor works.

Clearly the player.palladiumRegen is the code for the buff, as it also shows the hearts when regenerating.

You don't need anything special to do this.
In your UpdateArmorSet:

Code:

player.setBonus = Language.GetTextValue("ArmorSetBonus.Palladium");
player.onHitRegen = true;

For NPC selling, do this:

C#:

public override void SetupShop(Chest shop, ref int nextSlot) { if (downedBoss2 == true) { shop.item[nextSlot].SetDefaults(ItemID); nextSlot++; } }

Replace ItemID with and Item by it's ID.
For normal and unprepared if statements, do this:

C#:

if (downedBoss2 == true) { }

do you know what namespace i need to use since it says that "downedBoss" does not exist in the current context. The namespaces im currently using are Terraria, Terraria.ID and Terraria.Modloader.
