The first one I linked to was the GlobalNPC code, the second thing I sent was the ModNPC code. Go back to the GlobalNPC code any you'll see the checks for the NPCIDs.

You don't have a Mod class. You don't have a mod without a mod class. Example Below, fix it with your namespace and mod name and save it in the mods folder.

(Although, you might as well use this to get the build.txt and description.txt too: http://javid.ddns.net/tModLoader/generator/ModSkeletonGenerator.html)

(Also, your sword won't build since you deleted the dust....just use the link.)

Code: 
using Terraria.ModLoader;

namespace a
{
    class a : Mod
    {
        public a()
        {
            Properties = new ModProperties()
            {
                Autoload = true,
                AutoloadGores = true,
                AutoloadSounds = true
            };
        }
    }
}

thanks.
edit: now it shoots a few demon circle things in the bottom right... they do no damage... so what i mean is it shoots a few demon circle things to hte bottom right that do no damage, how to fix this?

In my experience this happens when the owner parameter of NewProjectile is set to 255 (which it defaults to). Replace it (or add it, if you didn't include it to begin with) with Main.myPlayer.

and how exactly do i do that? also, i found this line of code that says it goes at angle 45, 45, so thats probably pointing at where it goes, whats the code for mouse position?

Owner is the eight parameter of NewProjectile (after Knockback) and the first default parameter, so it's possible you're not actually using it yet. If Knockback is your last argument, insert , Main.myPlayer behind it. If it's not, find the argument directly after Knockback and change it to Main.myPlayer.

Not sure where you got angle from, but it seems like something used to calculate the velocity.

Mouse position is Main.mouseX and Main.mouseY (both ints).

You don't need to copy the whole folder, just either rename Vanilla Terraria.exe to TerrariaVanilla.exe or rename tmodloader Terraria.exe to tModLoader.exe.

So if I do this, how do choose which Terraria to open? I know nothing about modding, sorry to cause so much trouble :/

Is there a place I can get an image template or guide for the various Items?

I'm trying to make some custom armor and I want to make custom sprites to go with it but I'm looking through the Example Mod and I'm having a difficult time figuring out the patterns for the images. For example the ExampleHelmet has different numbers of pixels between all the various helmets in the image. Most are 36 pixels apart but some are 34 and I don't know if there are any other differences in there since I didn't check each and every one. Also I can't tell from the example file which sprite is used when.

Thanks in Advance

You just create shortcuts to both files and name one Terraria Vanilla and the other Terraria Mod. Then when you're in the mood for vanilla you run that one and when your working on your mod you run the other.

In your terraria folder, just do a folder called "Terraria Vanilla" and put the terraria.exe original file on it, after that, install tModLoader. If you want to use original terraria, just copy and replace the .exe again (you can do the same for the tModLoader, putting it in a "Terraria Mods" folder to play with mods after)

Yeah, the reason for that is because the player (when it walks or jump) it moves. The easyest way to make a custom armor is using other armor and draw on it (in other layer, obviously)


For me, i dont remember how to check if a projectile is active. Someone can help me? :p

I see, thanks! I just need to make 2 different folders and switch them around! I just want to know if the other files that come with the Terraria.exe will affect it.

No, they won't affect it. Although if you did it the way I told you, you would just right click drag with your mouse to the desktop to create the two shortcuts, no need to keep moving the exe around.

[doublepost=1460246075,1460245685][/doublepost]Thanks everyone for helping me so much!
 
I just copied all of the files into the MacOS folder of Terraria and now Terraria isn't opening. On Steam it says Running... then Syncing... then it stops, and does not open.
I thought I was done asking noob questions... :/
Is this a problem with the game itself? I put back the Vanilla Terraria.exe file and it still won't open.

Okay, so you're doing some rather strange stuff in your class. My advice to you, before we get to the code itself, is to use comment lines, and lots of them (comment lines are those lines that start with //). If I look at your evenSpread method, which isn't that difficult, it takes me a good few minutes to figure out what everything does, while with comment lines it would have taken me thirty seconds tops.

I cleaned up some general things, such as EvenSpread being static for no particular reason and redundant namespace usage (there are more messy things, but I can't change them with assurance that they'll work). This should fix the projectiles dealing no damage, but apart from that I didn't touch anything because I'm not sure what you are trying to do. Your mouseX was determining the type and your mouseY the damage, which I doubt was your original intention, so I reverted it to an earlier version you posted.

Does anyone know if it would be possible to make a constructed summon like there are a few staffs that each summon a piece of something and only when you have them all they will combine into this one huge thing?
