virtual void AddRecipes ()
 Override this method to add Recipes to the game.
Do note that this will be called for every instance of the overriding ModItem class that is added to the game.
The Basic Recipes Guideteaches how to add new recipes to the game and how to manipulate existing recipes.
To create a recipe resulting in this item, use CreateRecipe(int).
To create a recipe using this item as an ingredient, use Recipe.Create(int, int) and then pass in this or Type into Recipe.AddIngredient(ModItem, int) or Recipe.AddIngredient(int, int)
 
virtual bool AllowPrefix (int pre)
 Force a re-roll of a prefix by returning false.

 Allows you to modify which glow mask and in what color is drawn on the player's arms. Note that this is only called for body armor. Also note that this hook is only ever called through this item's associated equipment texture. More...
 
virtual void ArmorSetShadows (Player player)

 Allows you to prevent similar accessories from being equipped multiple times. For example, vanilla Wings. Return false to have the currently equipped item swapped with the incoming item - ie both can't be equipped at same time. This method exists because manually checking Player.armor in CanEquipAccessory(Player, int, bool) will not correctly account for modded accessory slots.
 
virtual ? bool CanAutoReuseItem (Player player)
 Allows you to modify the autoswing (auto-reuse) behavior of this item without having to mess with Item.autoReuse.
Useful to create effects like the Feral Claws which makes melee weapons and whips auto-reusable.

If false is returned, the CanConsumeAmmo, CanBeConsumedAsAmmo, OnConsumeAmmo, and OnConsumedAsAmmo hooks are never called. More...
 
virtual bool CanBeConsumedAsAmmo (Item weapon, Player player)

virtual ? bool CanCatchNPC (NPC target, Player player)
 Allows you to determine whether this item can catch the given NPC.
Return true or false to say the given NPC can or cannot be caught, respectively, regardless of vanilla rules.
Returns null by default, which allows vanilla's NPC catching rules to decide the target's fate.
If this returns false, CombinedHooks.OnCatchNPC is never called.

NOTE: this does not classify the given item as an NPC-catching tool, which is necessary for catching NPCs in the first place.
To do that, you will need to use the "CatchingTool" set in ItemID.Sets. More...
 
virtual ? bool CanChooseAmmo (Item ammo, Player player)
 Whether or not the given ammo item is valid for this weapon. If this, or CanBeChosenAsAmmo on the ammo, returns false, then the ammo will not be valid for this weapon.

Other items belonging to the same extractinator group should use ItemID.Sets.ExtractinatorMode[Item.type] = ModContent.ItemType<IconicItemForThisExtractinatorType>(); to indicate that they share the same extractinator output pool and to avoid code duplication. By default the parameters will be set to the output of feeding Silt/Slush into the Extractinator.

Note that position is the center of the inventory slot and origin is the center of the texture frame to be drawn, so the provided parameters can be passed into SpriteBatch.DrawString(SpriteFont, string, Vector2, Color, float, Vector2, float, SpriteEffects, float) to draw a texture in the typical manner. Returns true by default. More...
 
virtual bool PreDrawInWorld (SpriteBatch spriteBatch, Color lightColor, Color alphaColor, ref float rotation, ref float scale, int whoAmI)

virtual bool RangedPrefix ()
 Allows you to change whether or not a weapon receives ranged prefixes. Return true if the item should receive ranged prefixes and false if it should not.
 
virtual bool ReforgePrice (ref int reforgePrice, ref bool canApplyDiscount)
 Returns if the normal reforge pricing is applied. If true or false is returned and the price is altered, the price will equal the altered price. The passed reforge price equals the Item.value. Vanilla pricing will apply 20% discount if applicable and then price the reforge at a third of that value.
 
virtual void RightClick (Player player)
 Allows you to make things happen when this item is right-clicked in the inventory. By default this will consume the item by 1 stack, so return false in ConsumeItem(Player) if that behavior is undesired.

 This is where you set all your item's properties, such as width, damage, shootSpeed, defense, etc. For those that are familiar with tAPI, this has the same function as .json files. More...
 
virtual void SetMatch (bool male, ref int equipSlot, ref bool robes)
 Allows you to modify the equipment that the player appears to be wearing. This hook will only be called for body armor and leg armor. Note that equipSlot is not the same as the item type of the armor the player will appear to be wearing. Worn equipment has a separate set of IDs. You can find the vanilla equipment IDs by looking at the headSlot, bodySlot, and legSlot fields for items, and modded equipment IDs by looking at EquipLoader. If this hook is called on body armor, equipSlot allows you to modify the leg armor the player appears to be wearing. If you modify it, make sure to set robes to true. If this hook is called on leg armor, equipSlot allows you to modify the leg armor the player appears to be wearing, and the robes parameter is useless. Note that this hook is only ever called through this item's associated equipment texture. More...

Allows you to make things happen when this item is right-clicked in the inventory. By default this will consume the item by 1 stack, so return false in ConsumeItem(Player) if that behavior is undesired. This is only called if the item can be right-clicked, meaning ItemID.Sets.OpenableBag is true for the item type or either ModItem.CanRightClick or GlobalItem.CanRightClick return true.

Parameters

◆ SetMatch()

virtual void ModItem.SetMatch ( bool  male,
ref int  equipSlot,

)
virtual

Allows you to modify the equipment that the player appears to be wearing. This hook will only be called for body armor and leg armor. Note that equipSlot is not the same as the item type of the armor the player will appear to be wearing. Worn equipment has a separate set of IDs.

If this hook is called on body armor, equipSlot allows you to modify the leg armor the player appears to be wearing. If you modify it, make sure to set robes to true. If this hook is called on leg armor, equipSlot allows you to modify the leg armor the player appears to be wearing, and the robes parameter is useless. Note that this hook is only ever called through this item's associated equipment texture.

Parameters
maleif set to true [male].
equipSlotThe equip slot.
robesif set to true [robes].
