This is the hitbox of your sword.

No, 96x96 is the same as 480x480.

Snrasha · Jun 18, 2016

Install Visual Studio, this is very too usefull.
Try item.Hitbox = new Rectangle(0,0,480,480);

hmm, looks like for a sword, it's hitbox is the product of the texture width and height with the item.scale

Hello, I am all new to this but I made a mod with a sword being crafted from an Ore I made, and I know that I cant just type the name of the item there but I dont what to type there.

Code of my sword

Code:

            item.melee = true;            //if it's melee
            item.width = 70;              //Sword width
            item.height = 70;             //Sword height

    }
}

I'm not completely sure if this is the problem you mean, but I assume you mean this:

Code:

recipe.AddIngredient(OriciliumBar, 15);

That will not work. The correct format is this:

Code:

recipe.AddIngredient(mod.ItemType("OriciliumBar"), 15);

Thanks! I didint know it was so easy

I looked everywhere and I couldnot find it. Thank you once more!

Ok I got a major issue. My mod in general is failing to work, and I don't see what it is. I know for a fact that it is not my items because I tested them over in another mod changing the mod name in each item on the following line.

Code:

namespace (mod name).Items

Why is my mod not working?

Are you getting an error when trying to build/reload your mod? Is your mod loaded, but it doesn't show anything in game?

Nope. What happens is that there is no error message, I can turn it on and off like any other mod, but the items seize to exist. I can't craft them, or get them from the creative inventory from Hero's Mod which is compatible with other mods.

Do you have a class that derives from Mod in your mods rootfolder and does it set Autoload to true?

You can't, those colours are hard coded into the AI you're using.

You have a folder in Mod Source which contains all you mod items, NPCs, etc. Does this folder contain a class that is named the same as the folder?

TheTrueBrawler · Jun 19, 2016

I got no idea what you mean, but if you need to know here's a download link to my folder on the mod.

Look at the ExampleMod. In the root folder of the ExampleMod (called ExampleMod) is a file that is called ExampleMod.cs. This is the file I'm referring to. You'll want to copy this class over to your mod, change every instance of ExampleMod to your own mod name and remove all code inside the class, exept the one that is now named the same as your mod.

I don't exactly have a problem with my code but I'm not sure what all the 'zones' are in Terraria. I have certain items which I want to be dropped in certain biomes or 'zones' but there are two which I don't know the name for, well I do but not for the code.

Hell / Underworld - I tried .ZoneUnderworld and I also tried .ZoneHell neither work
and
Forest - I tried .ZoneForest which doesn't work so I'm using .ZoneJungle

Forest, Underworld and Ocean all don't have flags in Terrarias Code. Instead there's other things you need to check.

Forest - The player is in a forest, when no other biome flag is set and if they are overground, but still below sky height.
Underworld - The player is in the Underworld, if they are near the bottom of the world. The exact y-Coordinate differs depending on world size.
Ocean - The player is in the Ocean, if they are close to the eastern/western edge of the map and are neither underground nor in the sky.

So what should I put if Forest and Underworld don't have flags?

Snrasha · Jun 19, 2016

Hey, i have a small problem:

I have a rocket launcher, a rocket launched modded and a modded rocket.

So, with modded weapon where:
item.shoot = mod.ProjectileType("ArmoredRocket");
item.useAmmo = mod.ProjectileType("ArmoredRocket");
and same style for modded rocket.
item.shoot = mod.ProjectileType("ArmoredRocket");
item.ammo = mod.ProjectileType("ArmoredRocket");
I have a correctly rocket(explosion, same aistyle, aitype, etc ). But i want than this rocket can be shoot per vanilla rocket launcher.
So i put
item.shoot = mod.ProjectileType("ArmoredRocket");
item.ammo = 771; (< id of the type rocket)
But here, if vanilla rocket launcher detect ammo, he do not shoot projectile... so, question: I have missed where?

Thank you
