Standalone [1.3] tModLoader - A Modding API

a little question about the math of terraria. according to the wiki the lets say accessory damage bonuses are added together first right? (http://terraria.wiki.gg/Damage_types). why is it then when i for example call this in globalitem
Code: 
        public override void UpdateAccessory(Item item, Player player, bool hide)
        {
            if (item.type == ItemID.SniperScope)
            {
                player.rangedDamage -= 0.1f;
            }
        }
that the damage when equipping the sniper scope changes like it would multiplicately instead of deleting the sniperscope 10% boost? is tmodloaders hook somewhere different than i thought? how does it handle the damage boosts that
Code: 
        public override void UpdateAccessory(Item item, Player player, bool hide)
        {
            if (item.type == ItemID.SniperScope)
            {
                player.rangedDamage += 0.1f;
player.rangedDamage += 0.1f;
            }
        }
isnt the same as
Code: 
        public override void UpdateAccessory(Item item, Player player, bool hide)
        {
            if (item.type == ItemID.SniperScope)
            {
                player.rangedDamage += 0.2f;
            }
        }
or why does it completely :red: up when i go like
Code: 
        public override void UpdateAccessory(Item item, Player player, bool hide)
        {
            if (item.type == ItemID.SniperScope)
            {
                player.rangedDamage += 0.1f;
player.rangedDamage -= 0.1f;
player.rangedDamage += 0.1f;
player.rangedDamage -= 0.1f;
player.rangedDamage += 0.1f;
player.rangedDamage -= 0.1f;
player.rangedDamage += 0.1f;
player.rangedDamage -= 0.1f;
            }
        }
does it handle each boost on it own and then read what to do next? is the wiki wrong? can i not remove or change vanilla item damage boosts like sniper scope to 0% or avenger emblem to 15% because as the tooltip says 12%+3% is not 15% even though the wiki says they are added first.

wow facepalm me. why did i not think of that. if i want to remove 10% i should simply take it times 0.9... thx man

In the shoot method, change the position to Main.MouseWorld.X, etc, change the SpeedX tp 0 and SpeedY to a positive number
 
can i somehow detect if another mod is also loaded so i can change settings depending on if its loaded? something like
int test = base.mod.ItemType("SomeItemFromOtherMod")
if (test != 0)
{
//mod gefunden
}else //
could something like this work or is there an better way? for reference: i am the creator of both mods which were one mod before but i wanted to split the original mod into two but need to change some things depending on if both are loaded.

also is there a method to change a vanilla item into a modded item as soon as the game loads and only then (so he can change it back with a recipe if he wants to uninstall)? i know how to do it with right click
public override void RightClick(Player player)
{
int num = Item.NewItem((int)player.position.X, (int)player.position.Y, player.width, player.height, this.originalType, 1, false, 0, false, false);
Main.item[num].Prefix((int)base.item.prefix);
Main.item[num].newAndShiny = false;
}
but i would prefer this to be done automatically on load so the user doesnt need to right click the items in question. would load()/postsetupcontent() work for this? sry so many things i cant do on my own... this weekend isnt my greatest ^^

// Here is an example of how your npc can sell items from other mods.
using system.linq;
if (ModLoader.GetLoadedMods().Contains("SummonersAssociation"))
{
// Stuff
}

For your second question, I'm not sure why you'd want that. If you want to change a vanilla item, just change it in globalitem. Maybe if you explain more precisely I can help you find the best solution.
 
I'm attempting to make a mod, yet I have a problem.... I can't compile the mod. ;(

As mentioned earlier, when updating to 0.8, delete mp3sharp.dll.

If you want to change the damage, do that in the ModifyHitNPC hook.

public static bool downedBoss1 = false;
public static bool downedBoss2 = false;
public static bool downedBoss3 = false;
public static bool downedQueenBee = false;
public static bool downedSlimeKing = false;

Also note that "Main.rand.Next(1) == 0" is always true since the parameter in Next is the exclusive upper bound.

i know that this is 100%
"Main.rand.Next(1) == 0"

it was remains from the code i had as
"Main.rand.Next(20) == 0"


i cant seem to find the downedboss for WoF and thebrain



can i se a example on how to change damage in this hook ModifyHitNPC

Downed wall of flesh is just hardMode. The brain would share boss2 I think.

I haven't done anything with that hook personally, but you can say: damage = damage + 10; or whatever math you want

I've met with a horrible bug (maybe for me it's horrible) with my throwing knife's durability system in multiplayer... I dunno whether it is a exclusive bug for the multiplayer or whether it is fixable for now.
First I'd give a brief description of my throwing knife's durability system.
Every throwing knife is supposed to have 3 "items/parts":
Code: 
    public class IchorKnife : ModItem
    {
        public int durability = 1000;

        public override void SetDefaults()
        {
            item.name = "Ichor Knife";
            item.toolTip = "Decreases target's defense";
            item.autoReuse = true;
            item.useStyle = 1;
            item.shootSpeed = 12f;
            item.damage = 29;
            item.width = 18;
            item.height = 20;
            item.useSound = 39;
            item.useAnimation = 16;
            item.useTime = 16;
            item.noUseGraphic = true;
            item.noMelee = true;
            item.value = Item.sellPrice(0, 20, 0, 0);
            item.knockBack = 2.75f;
            item.melee = true;
            item.rare = 8;
            item.shoot = mod.ProjectileType("IchorKnifeProjectile");
        }

        }

        public override bool Shoot(Player player, ref Vector2 position, ref float speedX, ref float speedY, ref int type, ref int damage, ref float knockBack)

        }

        public override void LoadCustomData(BinaryReader reader)
        {
            durability = reader.ReadInt32();

  • Every throwing knife will be crafted with a maximum durability 1000.
  • The durability will be reduced upon using. (conduct by shoot hook)
  • The throwing knife will act like the vanilla throwing weapons. It has its 50% chance to drop the ammo when killed.
  • In this case, it won't drop the weapon itself, which is "IchorKnife". It will drop the exclusive item "IchorKnifeOnPickup" instead.
  • When the "IchorKnifeOnPickup" was picked up by a player,
  • if the player has the apt throwing knife and the durability was not full, he will pick it up, and increase the durability of the particular throwing knife, but the item won't appear in his inventory (the OnPickup hook returns false);
  • if the player does not has the throwing knife, he will also pick it up, but meanwhile a new and totally identical item will be created on his face, which makes it look like that he cannot pick up the item (I swear, this is the best case I can think out after several days' rocking my head).
However, this made-look-like-cannot-pickup function went dead when it comes to multiplayer. The player will pick up the "IchorKnifeOnPickup" regardless of their having the apt throwing knife facts. If a player possesses the throwing knife, yeah, the durability will get increased damn nice. But every player without the knife will swallow the "IchorKnifeOnPickup" as if they love to eat it...
This is the first time that I ever found that something worked like a charm in single player will end up screwing up in the multiplayer. This is frustrating and I have totally totally no idea about what's going on, and I need help!!!

EDIT: @jopojelly I duuno whether you're online but your profit pic is green. If you see this, well, please give a quick look. Thx:)
