The problem will most likely be because of the spaces in your class name. E.g. "public class the heart cooler : ModItem" should be "public class TheHeartCooler : ModItem" or something.

you should download visual studio, because it has linter and will help you with making code (linter is a program which highlights errors and shows potential solutions)

How to kill item on pickup? I want to make something like nebula bonuses, mana, or hearts, but when I write the code in

public override bool OnPickup(Player player) {}

, then it still stays in my inventory. How to solve this?

It stays because you're not actually doing anything; You're calling the method, but not telling it to do anything out of the ordinary. Try using this:

public override bool OnPickup(Player player)
{
   //<Whatever you want the item to do before dying, like adding a buff or healing>
   item.TurnToAir();
   return base.OnPickup(player);
}

Thank you! I tried this method before but it threw random errors and now I realized i used it the wrong way

I am using tmodloader 10.1.5. with Heros mod for kick and ban help. When I save and exit I do not see the world saving in the console. I have to manually click type save in the console and it will work. Isn't it supposed to auto safe on exit?

when you save and exit on the client, it won't affect the server. I think the server will autosave when you exit it properly.

BTW I know that c# is easy language but please, learn it before modding.

Hello. Assistance with the NPC implementation is needed. I would like to see one code example of an enemy which shoots something simple like arrow or other projectile instead of just melee damaging behavior. Example mod isn't giving proper information about it
[doublepost=1555863175,1555862995][/doublepost]Does anyone has any idea where to search or how to make worm-type enemy like wyvern. (head and all body is always not upside down)

How do I make my player invisible when the custom buff is on?

using Terraria;
using Terraria.ModLoader;

namespace ________.Buffs
{
    public class Ghost : ModBuff
    {
        public override void SetDefaults() {
            DisplayName.SetDefault("________");
            Description.SetDefault("_______");
            Main.buffNoTimeDisplay[Type] = true;
        }

        public override void Update(Player player, ref int buffIndex) {
            
        }
    }
}

I've tried things like "invisible", "invisibility", "opacity", "transparency", etc.
Please help!

Have you tried player.invis = true; ??
First one I found.

Can anyone help? So I got a new laptop and moved my characters via the steam cloud but when I downloaded tmodloader they all disapeared and are not in mygames/terraria/players because of how I transferred them. Is there any way to get them back?

how can i access the files of other mods?

 

[MadTeddyBear]

I'm getting this error when trying to build:

Expected resource not found:
Items/

Closest guess: (Is there a spelling or folder placement error?)
Items/GoldFishingLine
at Terraria.ModLoader.Mod.GetTexture(String name)
at Terraria.ModLoader.ModLoader.GetTexture(String name)
at Terraria.ModLoader.ModItem.AutoStaticDefaults()
at Terraria.ModLoader.Mod.SetupContent()
at Terraria.ModLoader.ModLoader.do_Load(Object threadContext)


Files are located in Documents\my games\Terraria\ModLoader\Mod Sources\MtbRepack\Items
Double checked that all of the namespaces were MtbRepack.Items, and the image files are all named correctly.

What am I missing?

I posted this: Standalone - [1.3] tModLoader - A Modding API

Not sure if this should go here or where I posted it.

Whenever I load up terraria, the game freezes on a white screen for ~1 second and then goes to the splash screen. after the screen ends, I'm greeted with this error. Does anyone know how to fix this?
