Show me your globalnpc so far.

Ok, While getting together the code and the error messages I found the "Show potential fixes" link in the error message in VS and I no longer have any errors. I was missing a using System.Collections.Generic; at the top of my code. Now I just flat out don't know how to use this function. What do I put in the EditSpawnPool function to remove any hostile creatures from the Spawn Pool?

Here's the code:

Code:

using System.Collections.Generic;
using Terraria;
using Terraria.ModLoader;

namespace AerlockMod.NPCs
{
    public class MyGlobalNPC : GlobalNPC
    {

        public override void EditSpawnRate(Player player, ref int spawnRate, ref int maxSpawns)
        {
            spawnRate = 999999;
            maxSpawns = 0;
        }

        public override void EditSpawnRange(Player player, ref int spawnRangeX, ref int spawnRangeY, ref int safeRangeX, ref int safeRangeY)
        {
            safeRangeX = 9999999;
            safeRangeY = 9999999;
        }

        public override void EditSpawnPool(IDictionary<int, float> pool, NPCSpawnInfo spawnInfo)
        {
            ----------> What goes here????? <----------
        }

    }
}

Ok now I have changed the name to "Sup" (Idk why ;p Why not?), and I am to add a nuclear sword with nuclear bar, unsuccesfully.... It keeps giving me this error:
LOG START
c:\Users\Jerry\Documents\My Games\Terraria\ModLoader\Mod Sources\Sup\Items\Nuclear.cs(29,25) : error CS0119: 'Sup.Items.NuclearBar' is a 'type', which is not valid in the given context
LOG END... Hehehehe

Well, line 29 is where it is complaining. Show us the code, since I can't guess the problem just from the error. (Well, sometimes I can)

Quick question: Is it possible to "resize" an item? Like, if I wanted to make a sword appear slightly bigger when swinging?

Or just set item.scale in setdefaults.

After infinite hours of searching and struggling in the source codes, I managed to make my throwing knife like this.
So now it does possess "durability". And the durability has indicated on the item.
However, a few details and bugs still remain here.

The weapon can be crafted with 999 durability, guess it has something to do with the statement of durability. And this durability can get reduced, 'cause of the operator in Shoot hook. But it can't get increase nicely when it is picked up. Is there anything wrong with On Pickup? And I conjectured that there may be bugs when multiple throwing knives are in play. Won't they get messed up with each other's durability? I dunno. I just did it like this, but I got totally no idea how the codes work out and how the data system is arranged.

As for the indication, it's fine. But it seems how hard I tried, I can't make it exactly like how the ammo appears to be. How should I set those parameters to get the durability look like the ammo? The position is quiet OK now. Maybe the color and font need to be specified. Another thing is that the numerical durability won't be zoomed when the item is chosen. I could see the ammo are zoomed normally.

Prefix still sucks.... It just does't want to have prefixes till I turn the item.melee on!!! How am I gonna fix this. Run out of mind.

This is tricky anyways.

1. on pickup is called on the item you pick up, so you are increasing the durability of the picked up item to 1000 and then throwing it away. You'll have to check the inventory for your item, increase it if it is there, or allow the item to be pick up is it's not. You'll want to make sure it's not 999 though.

The durabilities should stay consistent per instance.

2. Zooming the text: use the scale passed in.

3. I forget, what's the point of making it thrown? you just want the damage calculations of thrown, but you also want prefixes?

- Aerlock

That spawn rate will basically prevent any spawns, I think.

Anyway,

Code:

public virtual void EditSpawnPool(IDictionary<int, float> pool, NPCSpawnInfo spawnInfo)

Allows you to control which NPCs can spawn and how likely each one is to spawn. The pool parameter maps NPC types to their spawning weights (likelihood to spawn compared to other NPCs). A type of 0 in the pool represents the default vanilla NPC spawning.

...so as Blue told you earlier, remove 0 from the pool and add back in the vanilla npc you want to spawn.

Code:

        public override void EditSpawnPool(IDictionary<int, float> pool, NPCSpawnInfo spawnInfo)
        {
            pool.Remove(0);
            pool.Add(NPCID.Squirrel,.1f);
            pool.Add(NPCID.Bird,.1f);
            pool.Add(NPCID.GoldBird,.1f);
            pool.Add(NPCID.GoldBunny,.1f);
            pool.Add(NPCID.GoldButterfly,.1f);
            pool.Add(NPCID.GoldWorm,.1f);
        }

Of course, I don't expect anything to spawn with the other methods you have there.

Yeah, prefixes are in need. Since I'm making this whole new class of weapons... So I'd love to add prefixes to them, which will make them more look like a formal weapon or something...
And as for the check for the inventory... I actually tried that one. But it seems the compiler is not happy with my arbitrary item.durability, and it says my missing "using"?

EDIT: BTW, what's the right color should I use to make the indication look like ammo?
EDIT: And, if I define "scale", what bool should I use to make sure whether the item is chosen or not?
EDIT: Okay, guess I always forgot something here and there. One more question here: where am I supposed to find the IDs of all the sounds? Like which number refers to hurt, and which number refers to picking items?

        }

THANK YOU! The pool.<action> was the code/call I was missing. I couldn't find any examples of what to put in there. And yes with the spawnrate as it is I get nothing to spawn and that's what I'm trying to fix. I want the bunnies and birds and bugs and the Town NPCs to spawn, but not the hostile NPCs. Once I get my Spawn Pool together I'll put that spawn rate back to a reasonable number and hopefully not get flooded in bunnies.

Now for a couple questions:

In the pool.Add(NPCID.GoldButterfly,.1f) call I'm assuming the .1f is the weight of the NPC in the pool, correct?
Is there a default total weight or just the total of whatever I have in the Add list?
Looking at the NPC list in the documentation on the Github site I see several NPCs that have the same Name but different IDs (Duck, Worm, Scorpion, etc.). If I add those using the pool.Add(NPCID.<Name>,.1f); call will it add all the squirrels, ducks, worms, etc.? Or do I need to add all of those by ID?

well, you can't access durability on Item, since Item doesn't have durability. You need to access the field on your ModItem, but not just ModItem, but the
IchorThrowingKnife. so, something like if item.type == mod.ItemType("IchorThrowingKnife"){ (IchorThrowingKnife)(item.modItem).durability++}

Yeah, you'll want to read up on inheritance and casting.

Are you talking about PreDrawInInventory and scale? why would you define it? Just use the one passed in.

There is a mod called "Dust and Sound Catalogue tModLoader", look in the forum for it, it should help you figure out sounds.

I don't know the color.

K, just make sure you read the documentation on those methods. They might be backwards from what you expect.

Each NPCID is a different NPC, so you'll want to add red, gold, and regular squirrel, etc.

The default total weight of vanilla npc is 1. So you'll need to worry about mod npc and whatever npc you add back in. Their totals will be the total.

I got it like this, compiler is not happy again:

Code:

        public override bool OnPickup(Player player)
        {
            Main.PlaySound(0, (int)player.position.X, (int)player.position.Y, 7);
            for (int i = 0; i < 50; i++)
            {
                Item item2 = player.inventory[i];
                if (item2.stack > 0 && item2.type > 0 && item2.type == mod.ItemType("IchorThrowingKnife"))
                {
                    (IchorThrowingKnife)(item2).durability++
                    break;
                }
            }
            return false;
        }

And I'm still not clear about your brilliant " Just use the one passed in." idea... sorry for that.
But what I'm tryna do is to indicate this durability on the item. As for now, I'm kinda realizing most parts of it. Question is that the numerical durability won't get zoomed (which the ammo of gun and bow will).
This is what I write for the indication:

Code:

            Main.spriteBatch.DrawString(Main.fontItemStack, durability.ToString(), new Vector2(position.X - 8f, position.Y + 10f), Color.Black, 0f, default(Vector2), 0.7f, SpriteEffects.None, 0f);

And after you said I should use a scale pass in, I figured I should do something like:

Code:

float scale;
if(The item is chosen currently)
scale = 1f;
else scale = 0.7f;

Main.spriteBatch.DrawString(Main.fontItemStack, durability.ToString(), new Vector2(position.X - 8f, position.Y + 10f), Color.Black, 0f, default(Vector2), 0.7f, SpriteEffects.None, 0f);

And, specifically, how should the "The item is chosen currently" part be written?

No, just replace the 0.7f with scale. It is one of the parameters of PreDrawInInventory. The scale will change automatically if it is chosen.

(IchorThrowingKnife)(item2).durability++ won't work because you cant cast Item to IchorThrowingKnife. IchorThrowingKnife inherits from ModItem, and item.modItem is what you want.

Try: (IchorThrowingKnife)(item2.modItem).durability++

Get ya. But It still says "only assignment,call,increment,decrement,await and new can be used"... Any idea about this?

Okay, so I just updated my mod to 0.8, changed all the stuff I should change and then this happens when trying to add recipes:

Code:

The item radiantingot does not exist in the mod MokkelMod.
If you are trying to use a vanilla item, try removing the first argument.
   at Terraria.ModLoader.ModRecipe.AddIngredient(Mod mod, String itemName, Int32 stack)
   at MokkelMod.Items.Accessories.elementalboots.AddRecipes() i c:\Users\maste\Documents\My Games\Terraria\ModLoader\Mod Sources\MokkelMod\Items\Accessories\elementalboots.cs:linje 39
   at Terraria.ModLoader.ModLoader.AddRecipes()

   at Terraria.ModLoader.ModLoader.do_Load(Object threadContext)

I am 100% sure that radiantingot exists and is called that.

This piece of code is from the tModloader help thread:

Code:

        public override bool Shoot(Player player, ref Microsoft.Xna.Framework.Vector2 position, ref float speedX, ref float speedY, ref int type, ref int damage, ref float knockBack)
        {
            float spread = 45f * 0.0174f; //Replace 45 with whatever spread you want
            float baseSpeed = (float)Math.Sqrt(speedX * speedX + speedY * speedY);
            double startAngle = Math.Atan2(speedX, speedY)- spread/2;
            double deltaAngle = spread/8f;
            double offsetAngle;
            int i;
            for (i = 0; i < 2;i++ ) //Replace 2 with number of projectiles
            {
                offsetAngle = startAngle + deltaAngle * i;
                Terraria.Projectile.NewProjectile(position.X, position.Y, baseSpeed*(float)Math.Sin(offsetAngle), baseSpeed*(float)Math.Cos(offsetAngle), item.shoot, damage, knockBack, item.owner);
            }
            return false;
        }

Hmm, everything looks right, unless you didn't set autoload in your mod properties.

Here is the code when it compiles.

            recipe.AddRecipe();

    }
}

I got the parenthesis wrong: ((IchorThrowingKnife)item2.modItem).durability++;

Also, there's no point in having both DurabilitySave and durability
