Anyone know what the heck this is? It does this every time I click single player. I don't know how to fix it.

Hey all, does anyone know how to make a sword have a custom swing animation? I want to make a sword that first swings downwards and then upwards, kind of like if someone would be mindlessly swinging it around. My current idea is to try using UseStyle to customize the item's animation, but correct me if I'm not using the code correctly.

I've been working on a boss mob, and the boss isn't targeting the player, It's target is nothing near the player. it doesn't fly above the player, and it doesn't update based on the player's position, I feel like it isn't targeting them, how do I set the target to the nearest player?

And for later use, how do I despawn the mob if there are NO living players, or the nearest player is more than 600 blocks away, roughly 2 biomes away?

EDIT:

I figured it out, it's a for loop

    for (int i = Main.player.Length; i>=0; i--){
 
        if (Distance(Main.players[i].Center, NPC.Center) < distance)
        {
            distance = Vector2.Distance(Main.player[i].Center, NPC.Center);
            target = Main.player[i];
        }
    }

How do I give an npc god mode? I need a phase where my boss goes invulnerable for a while while they turn the game into a bullet hell

Hey, I'm trying to make a mod that adds an NPC. It's supposed to shoot bullets from a sniper rifle. The bullets work but the sniper rifle won't show up when the NPC fires. heres the code snippet.
public override void DrawTownAttackSwing(ref Texture2D item, ref int itemSize, ref float scale, ref Vector2 offset)
{
item = ModContent.Request<Texture2D>("Terraria/tModLoader/ModSources/MeNPC/Content/Items/Weapons" + ItemID.SniperRifle).Value;
itemSize = 40;
}
If anyone could help me I would appreciate it, thank you

If you want to use the vanilla texture, TextureAssets.Item[ItemID.SniperRifle].Value should work.
If you get an error about TextureAssets, you need using Terraria.GameContent; in your file.

I tried it. I didn't get an error code (like last time) But the sniper rifle still doesn't appear when the npc attacks. Heres the new code, maybe I just put it in wrong?

public override void DrawTownAttackSwing(ref Texture2D item, ref int itemSize, ref float scale, ref Vector2 offset)
{
item = TextureAssets.Item[ItemID.SniperRifle].Value;
itemSize = 40;
}
Also I'm including a video of the attack incase that helps.

You need to override `DrawTownAttackGun` instead of `DrawTownAttackSwing`. Apologies for not catching that earlier.

Got this error now.
(new code)
public override void DrawTownAttackGun(ref Texture2D item, ref int itemSize, ref float scale, ref Vector2 offset)
{
item = TextureAssets.Item[ItemID.SniperRifle].Value;
itemSize = 40;
}

Hello, I am trying to localize other mods. Please help me, I don't understand the two files with dll and pdb formats. Without them localization is not working and I don't know how to create them

like this(I took this as an example from another localization)

That's it, I figured it out, these files are created during compilation

Hello! I`m trying to make my first mod, and I need some help.
I want to make weapon and armor with growing stats. I made weapon which damage and attack speed is increased with hitting enemies. But i got huge issues with armor. I don't understand how to make it increase it's defense and my max health. So i have a few questions after playing with different stats.
1) Is it possible to transfer value of variable to another item in visual studio? (i.e. transfer exp value from my weapon to armor)
2) How to check if player got damaged, and one-time damage exceed some level?
Thanks!

Ok, so I'm trying to make a mod, and it's not my first time, but for some reason I cannot get it to verify my item...

Here is my code:

using Terraria;
using Terraria.ModLoader;
using Terraria.GameContent.Creative;
using Terraria.ID;

namespace ClasslessEndgame.Content.Items.Tools
{
internal class LuminitePickaxe : ModItem
{
public override void SetStaticDefaults()
{
DisplayName.SetDefault("Luminite Pickaxe");
CreativeItemSacrificesCatalog.Instance.SacrificeCountNeededByItemId[Type] = 1;
}
public override void AutoStaticDefaults()
{
Item.width = 38;
Item.height = 38;

Item.useTime = 12;
Item.useAnimation = 6;
Item.autoReuse = true;
Item.useStyle = ItemUseStyleID.Swing;
Item.useTurn = true;

Item.DamageType = DamageClass.Melee;
Item.damage = 80;
Item.knockBack = 5.5f;

Item.value = Item.buyPrice(gold:7);
Item.rare = ItemRarityID.Red;

Item.pick = 225;
Item.tileBoost = 4;
}
public override void AddRecipes()
{
CreateRecipe()
.AddIngredient(ItemID.LunarBar, 10)
.AddIngredient(ItemID.FragmentNebula, 12)
//.addIngredient(ModContent.ItemType<UniverseFragment>(), 12)
.AddTile(TileID.LunarCraftingStation)
.Register();
}
}
}


I don't know what is going on, I can't get the item to show up in game, also if it helps, the error message is this:
Object not set to an instance of an object (See client.log for full details)


NEVERMIND!!!!! I fixed it

For context, I wanted to play an older version of a mod. That called for an old Tmodloader version in order to use it.
I downloaded version 0.10.1 from github and extracted the folder. I then ran the executable and was met with this error:

I then uninstalled terraria vanilla and tried again, being met with the same error.
Due to the terms used in the error, I do not understand what this error means nor how to fix it.

[Venturge]

Everytime an Eidolon Wyrm, a Reaper Shark or a Gulper Eel (Infernum Mode is on so they have their edited behavior) spawns in my world, my game crashes, I'm using Calamity, Infernum and some other QoL mods.
Here's the crash log if someone has a fix.
