This page explains how the game stores and parses item data. This is an advanced guide for mod developers.
This page explains how the game stores and parses object-type item data. For items in general, see [[Modding:Items]].


==Introduction==
==Overview==
===Overview===
Objects are the default type for items in inventories or in the world. Depending on their data, they can be placed, picked up, eaten, sold to shops, etc.
Items are divided into several types:


{| class="wikitable"
They have [[Modding:Items#Item types|item type]] <code>(O)</code> (or <code>ItemRegistry.type_object</code> in C# code), their data in <samp>Data/Objects</samp>, their icon sprites in <samp>Maps/springobjects</samp> or <samp>TileSheets/Objects_2</samp> by default, and their code in <samp>StardewValley.Object</samp>. See [[/Object sprites|a table of sprites and their corresponding indexes]].
|-
! type
! summary
|-
| [[#Objects|objects]]
| The default type for items in inventories or placed in the world.
|-
| [[#Big craftables|big craftables]]
| Craftable items which can be placed in the world and are two tiles tall.
|-
| [[#Boots|boots]]
| Items that can be equipped in the player's [[footwear]] slot.
|-
| [[#Clothing|clothing]]
| Cosmetic items that can be equipped in the player's [[Tailoring|pants and shirt]] slots.
|-
| [[#Furniture|furniture]]
| Decorative items which can be placed in the world, including chairs which the player can sit on.
|-
| [[#Hats|hats]]
| Items that can be equipped in the player's [[hats|hat]] slot.
|-
| [[#Tools|tools]]
| Items that can be swung or used by the player to perform some effect.
|-
| [[#Weapons|weapons]]
| Tools that can be used by the player to damage monsters.
|}
 
For each item type, the game has two files in its <samp>Content</samp> folder (which can be [[Modding:Editing XNB files#unpacking|unpacked for editing]]):
* a ''data asset'' for the text data for its items (names, descriptions, prices, etc);
* and a ''spritesheet'' for the in-game item icons.
 
Each item has a <samp>ParentSheetIndex</samp> field which is its position in the item type's spritesheet, starting at 0 in the top-left and incrementing by one as you move across and then down. For example, hat #0 is the first sprite in <samp>Characters/Farmer/hats</samp>. The <samp>ParentSheetIndex</samp> is also used to identify the item itself; since spritesheet indexes aren't unique (''e.g.,'' there's both a hat #10 and object #10), code needs to check the type too like <code>item is Weapon weapon && weapon.ParentSheetIndex == 4</code>.
 
Flooring and wallpaper are not in any of these types and are not currently documented in this wiki.
 
See the sections below for details on each item type.
 
===Get a list of items===
With [[Modding:Player Guide/Getting Started|SMAPI installed]], you can [[Modding:Console commands#Console commands|run the <samp>list_items</samp> console command]] in-game to view/search items and their IDs.
 
===Define a custom item===
Every item must be assigned a unique <samp>ParentSheetIndex</samp> within its type, and that index must fit within the item type's spritesheet.
 
Adding custom items to the data assets and spritesheets directly is '''not recommended''', since it's very easy to conflict with other mods or cause game errors. Instead you should create a content pack for {{nexus mod|1720|Json Assets}}, which coordinates dynamic item ID assignment so multiple custom item mods can work together.


==Common data==
==Data format==
===Quality===
The object data in <samp>Data/Objects</samp> consists of a string → model lookup, where...
Each item has a quality level which (depending on the item type) may affect its price, health boost, etc. The valid qualities are:
* The key is the unqualified [[Modding:Common data field types#Item ID|item ID]].
* The value is a model with the fields listed below.

| <samp>Type</samp>
| <samp>2</samp>
| The item's general type, like Arch (artifact) or Minerals. The vanilla types are: <samp>Basic</samp>, <samp>Arch</samp> (artifact), <samp>Litter</samp> (e.g. debris), <samp>Minerals</samp>, <samp>Quest</samp>, <samp>Crafting</samp>, <samp>Fish</samp>, <samp>Cooking</samp>, <samp>Seeds</samp>, <samp>Ring</samp>, <samp>interactive</samp>, and some placeholder values like <samp>asdf</samp>.
| <samp>Object.highQuality</samp>
|-
| iridium
| <samp>4</samp>
| <samp>Object.bestQuality</samp>
|}


===Categories===
'''Caution:''' adding custom items with the <samp>Arch</samp> type is inadvisable as it often leads to [[Artifact Spot|artifact spot]]s becoming broken and not giving any items.
Each item also has a category (represented by a negative integer). In code, you can get an item's category value from <samp>item.Category</samp>, and its translated name from <samp>item.getCategoryName()</samp>. Here are the valid categories:


{| class="wikitable sortable"
'''Note:''' The "Type" affects whether an item shows up in the collections menu. For example, items with <samp>Type: Cooking</samp> will show up as silhouettes in the cooked items collection menu, items with <samp>Type: Minerals</samp> will show up as silhouettes in the mineral collection menu, etc. However, the [[Modding:Items#Categories|Category]] of the item must also be the correct number or the item will not count toward Perfection/Achievements. For example, if an item has Type: Cooking, it must also be "Category": -7 in order to count toward the "Gourmet Chef" achievement and Perfection.

{{collapse|Console commands|content=
===Appearance===
With the {{nexus mod|3101|Console Code}} mod installed, you can run this command in the SMAPI console to see a list of objects by category:
 
<pre>cs return string.Join(`\n`, Game1.objectInformation.Keys.Select(key => new StardewValley.Object(key, 1)).GroupBy(item => item.Category, item => item.Name).OrderByDescending(p => p.Key).Select(p => $`{p.Key}: {string.Join(`, `, p.OrderBy(name => name))}`));</pre>
}}
 
===Context tags===
A ''context tag'' is an arbitrary data label attached to items. These can produce various effects in-game, or may be informational only.
 
The game generates some tags based on the game data (like the item quality), and others are defined in the <samp>Data/ObjectContextTags</samp> data asset (which consists of a string→string dictionary, where the key is the item's internal name ''or'' the alternative ID matching the <samp>id_{{t|type}}_{{t|identifier}}</samp> tag, and the value is a comma-delimited list of tags to add).
 
Here's an ''incomplete'' list of context tags added or used in the base game. Mods can add custom context tags, which aren't listed here.
 
<dl style="margin-left: 2em;">
<dt>Added automatically for all items:</dt>
<dd>

|-
|-
| <samp>fish_{{t|metadata}}</samp>
| <samp>Texture</samp>
| Added automatically for a fish item based on [[Modding:Fish data|its metadata in <samp>Data/Fish</samp>]].
| The asset name for the texture containing the item's sprite. Defaults to <samp>Maps/springobjects</samp>.
 
For [[Crab Pot|crab pot]] fish (''i.e.'' those with type <samp>trap</samp>):
 
{| class="wikitable"
|-
|-
! context tag
| <samp>SpriteIndex</samp>
! notes
| The sprite's index within the <samp>Texture</samp>, where 0 is the top-left sprite.
|-
|-
| <samp>fish_trap_location_{{t|water type}}</samp>
| <samp>ColorOverlayFromNextIndex</samp>
| Based on field 2 ('darting randomness'). For example, <samp>fish_trap_location_ocean</samp>.
| ''(Optional)'' When drawn as a colored object, whether to apply the color to the next sprite in the spritesheet and draw that over the main sprite. If false, the color is applied to the main sprite instead. Default false.

|-
| <samp>fish_difficulty_{{t|difficulty}}</samp>
| Based on field 1 ('chance to dart'), where {{t|difficulty}} is one of <samp>easy</samp> (0–33), <samp>medium</samp> (34–66), <samp>hard</samp> (67–100), or <samp>extremely_hard</samp> (101+). For example, <samp>fish_difficulty_hard</samp>.
|-
|-
| <samp>fish_motion_{{t|motion}}</samp>
| <samp>Edibility</samp>
| Based on field 4 ('location'). For example, <samp>fish_motion_floater</samp>.
| ''(Optional)'' A numeric value that determines how much energy (edibility × 2.5) and health (edibility × 1.125) is restored when this item is eaten. An item with an edibility of -300 can't be eaten, values from -299 to -1 reduce health and energy, and zero can be eaten but doesn't change health/energy. Default -300.
|-
|-
| <samp>fish_favor_weather_{{t|weather}}</samp>
| <samp>IsDrink</samp>
| Based on field 7 ('weather'). For example, <samp>fish_favor_weather_sunny</samp>.
| ''(Optional)'' Whether to drink the item instead of eating it. Default false.
|}
|-
|-
| <samp>id_{{t|type}}_{{t|identifier}}</samp>
| <samp>Buffs</samp>
| Added automatically as an alternative ID. The {{t|type}} is one of <samp>B</samp> (boots), <samp>BBL</samp> (big craftable recipe), <samp>BL</samp> (object recipe), <samp>BO</samp> (big craftable), <samp>C</samp> (clothing), <samp>F</samp> (furniture), <samp>H</samp> (hat), <samp>O</samp> (object), <samp>R</samp> (ring), <samp>W</samp> (melee weapon), else blank. The {{t|identifier}} is the item's parent sheet index. For example, [[pufferfish]] has value <samp>id_o_128</samp> (object #128).
| ''(Optional)'' The buffs to apply to the player when this item is eaten, if any. Default none.
|-
| <samp>item_{{t|name}}</samp>
| Added automatically based on the item name. The name is trimmed, lowercase, with spaces replaced with underscores, and with single quotes removed. For example, [['1000 Years From Now']] has context tag <samp>item_1000_years_from_now</samp>.
|}

|-
|-
| <samp>jelly_item</samp><br /><samp>juice_item</samp><br /><samp>pickle_item</samp><br /><samp>wine_item</samp>
| <samp>Id</samp>
| For items produced by the [[keg]] or [[Preserves Jar|preserves jar]], the preserved item type.

| <samp>preserve_sheet_index_{{t|id}}</samp>
| <samp>Duration</samp>
| For items produced by the [[keg]] or [[Preserves Jar|preserves jar]], the parent sheet index for the original item that was produced. For example, blueberry [[wine]] has <samp>preserve_sheet_index_258</samp>, where 258 is the [[blueberry]] item's index.
| ''(Optional if <samp>BuffId</samp> is set)'' The buff duration measured in in-game minutes. This can be set to <samp>-2</samp> for a buff that should last for the rest of the day.
|-
|-
| <samp>quality_none</samp><br /><samp>quality_silver</samp><br /><samp>quality_gold</samp><br /><samp>quality_iridium</samp>
| <samp>BuffId</samp>
| Added automatically based on the item quality.
| ''(Optional)'' The unique ID of a buff from <samp>Data/Buffs</samp> to apply, or <samp>null</samp> to ignore <samp>Data/Buffs</samp> and set the ID to <samp>food</samp> or <samp>drink</samp> depending on the item's <samp>IsDrink</samp> field.

</dd>


<dt>Context tags from <samp>Data/ObjectContextTags</samp>:</dt>
If a buff from <samp>Data/Buffs</samp> is applied and you also specify other fields, here's how the buff data is combined:

|-
|-
! context tag

! effect
! result
|-
|-
| <samp>color_*</samp>
| <samp>Duration</samp><br /><samp>IconTexture</samp><br /><samp>IconSpriteIndex</samp><br /><samp>GlowColor</samp>
| The color produced by this item when the player [[Dyeing#Dye Pots|dyes clothing]] at [[2 Willow Lane|Emily's house]]. The context tag only affects which of the six color dye pots it can be placed in; for example, <samp>color_red</samp> and <samp>color_dark_red</samp> are both placed in the red pot, but they don't produce different colors.
| If specified, the value in <samp>Data/Objects</samp> is used instead of the one in <samp>Data/Buffs</samp>. If omitted, defaults to the value from <samp>Data/Buffs</samp>.

| <samp>color_blue</samp>, <samp>color_dark_blue</samp>, <samp>color_dark_cyan</samp>, <samp>color_light_cyan</samp>, <samp>color_cyan</samp>, <samp>color_aquamarine</samp>
| The values from both entries are combined (e.g. +1 speed in <samp>Data/Objects</samp> and +1 speed in <samp>Data/Buffs</samp> results in +2 speed).

Some game data also references context tags in a generic way. For example, you can add custom tags for an item to <samp>Data/ObjectContextTags</samp>, then reference them in the fish pond data. Specifically:
{| class="wikitable"
|-
|-
! game data
| <samp>IsDebuff</samp>
! effects
| ''(Optional)'' Whether this buff counts as a debuff, so its duration should be halved when wearing a Sturdy Ring. Default false.
|-
|-
| [[Modding:Fish Pond data|fish ponds]]
| <samp>IconTexture</samp>
| In <samp>Data/FishPondData</samp>, used to match fish that can be placed in the pond (see [[Modding:Fish Pond data#RequiredTags|<samp>RequiredTags</samp> in the fish pond data]]).
| ''(Optional)'' The asset name for the icon texture to load. This must contain one or more 16x16 icons in a grid of any size. If omitted, the game will draw a default icon based on the <samp>BuffId</samp> and <samp>CustomAttributes</samp> fields.
|-
|-
| [[Modding:Special orders|special orders]]
| <samp>IconSpriteIndex</samp>
| In <samp>Data/SpecialOrders</samp>, used to match items that meet the quest objectives (see [[Modding:Special orders#Context tags|<samp>AcceptedContextTags</samp> in the special order data]]).
| ''(Optional)'' The buff's icon index within the <samp>IconTexture</samp>, where 0 is the top-left icon. Default 0.
|-
|-
| tailoring
| <samp>GlowColor</samp>
| In <samp>Data/TailoringRecipes</samp>, used to match items that are needed for a recipe.
| ''(Optional)'' The glow color to apply to the player. See [[Modding:Common data field types#Color|color format]]. Default none.
|-
|-
| [[Modding:Gift taste data|gift tastes]]
| <samp>CustomAttributes</samp>
| In <samp>Data/NPCGiftTastes</samp>, used to set character likes and dislike for every item using the context tag.
| The custom buff attributes to apply, if any.

They have their data in <samp>Data/Objects</samp>, their icon sprites in <samp>Maps/springobjects</samp>, and their code in <samp>StardewValley.Object</samp>. See [[Modding:Items/Object sprites|a table of sprites and their corresponding indexes]].
 
===Data format===
The object data in <samp>Data/Objects</samp> consists of an integer→string dictionary with entries like this:
<syntaxhighlight lang="json">
  "18": "Daffodil/30/0/Basic -81/Daffodil/A traditional spring flower that makes a nice gift."
</syntaxhighlight>
 
For each entry in the data asset:
* The key (before the colon) is the item ID and its sprite index within the [[Modding:Items/Object sprites|object spritesheet]] (saved as <samp>ParentSheetIndex</samp> in-code).
* The value (after the colon) is a slash-delimited string with the fields listed below. Fields 0–5 are used by most object; fields 6–11 are only used for a select few items. The objects with keys 516–534 (<samp>Ring.ringLowerIndexRange</samp> through <samp>Ring.ringUpperIndexRange</samp>) and 801 (wedding ring) are hardcoded as rings.


This consists of a model with any combination of these fields:

|-
|-

| <samp>CustomFields</samp>
| type and category
| ''(Optional)'' The [[Modding:Common data field types#Custom fields|custom fields]] for this entry.  
| &#32;
This is the item's type (string) and, in most cases, a category (negative integer), separated by a space like <samp>Fish -4</samp>. For some types the category is omitted.
 
While [[#Categories|categories]] are frequently referenced in other parts of the game, types appear to be apocryphal data from early in the game's development. As such, some of them are not very well understood. The types used in <samp>Data/Objects</samp> and their purposes (as is currently understood) are as follows:
*<samp>Ring</samp>, used for all rings, even the [[Wedding Ring]]. Category is ommitted, though every <samp>Ring</samp> type is automatically given the category <samp>-96</samp>.
*<samp>Fish</samp>, used not only for fish but all items gained through fishing. Always paired with <samp>-4</samp> for true fish or <samp>-20</samp> for junk items such as [[Joja Cola]].
*<samp>Arch</samp>, used for artifacts, presumably standing for "archaeology." Category is ommitted, though every <samp>Arch</samp> type is automatically given the category <samp>0</samp>. Is ''not'' used for Gems or Minerals. '''Adding custom items of the <samp>Arch</samp> type is not recommended, as it can break all Artifact Spots in the game.'''
*<samp>asdf</samp>, used for a handful of items the player isn't intended to ever have in their inventory, such as an Artifact Spot or Secret Note. Category is ommitted.
*<samp>Seeds</samp>, used for seeds, starters, shoots, etc. Always paired with the category <samp>-74</samp>.
*<samp>Crafting</samp>, used for a variety of crafted items. Notably, however, there are some non-craftable items with this type: all tree seeds, various "Weeds", the [[Dwarvish Translation Guide]], [[Coffee]], [[Stardrop]], [[Galaxy Soul]], [[Horse Flute]], and supply crates. Category is either ommitted or <samp>-8</samp>, <samp>-24</samp>, or <samp>-74</samp>.
*<samp>Quest</samp>, used for quest items as well as [[Golden Coconut|Golden Coconuts]]. Category is ommitted.
*<samp>Basic</samp>, a general type for a myriad of items.
*<samp>Cooking</samp>, used for cooked items. Not used for cooking ingredients. Always paired with category <samp>-7</samp>.
*<samp>Minerals</samp>, used for Gems and Minerals. Paired with categories <samp>-2</samp> or <samp>-12</samp>, respectively.

* For a food or drink item, set this to <samp>food</samp> or <samp>drink</samp> respectively. This enables the remaining fields, and changes which animation/sound is played when the player consumes the item. Any other value is ignored.
* For a geode or geode-esque item ([[Artifact Trove|275]], [[Geode|535]], [[Frozen Geode|536]], [[Magma Geode|537]], or [[Omni Geode|749]]), this is a space-delimited list of object IDs. There's a roughly 50% chance that the geode item will drop one of these items (the other drops are hardcoded).
* For artifacts, this is a list of locations followed by a number less than 1. The game checks this field first when digging up an Artifact Spot. If nothing is randomly chosen from this list, the game checks the data in <samp>Data/Locations.xnb</samp>.
* For fish and other fished items, this a string in the format of <samp>{{t|times}}^{{t|seasons}}</samp>, where {{t|times}} is a space-deliminated list of <samp>Day</samp> or <samp>Night</samp>, and {{t|seasons}} is the same with seasons instead. Appears to be unused or redundant, as the data for what times and seasons fish appear in is stored in <samp>Data/Fish.xnb</samp>.

|}


===Notes===
===Geodes & artifact spots===
* Items that have a number in index 6 (the "Crafting" field) show buggy information in-game (''e.g.,'' Bean Hotpot prior to version 1.4). Items that have a number in the "Attack" field display the Attack icon and a number, but no description. It's unclear how these buffs work (if at all).
* '''Adding custom items with the <samp>Arch</samp> type is inadvisable as it often leads to Artifact Spots becoming broken and not giving any items.'''
* Named [[buffs]] (like [[Oil of Garlic]], [[Life Elixir]], or [[Buffs#Tipsy|Tipsy]]) are implemented in code and can't be set in the food buff fields.
* The spritesheet and data have items that can't normally be found in the player inventory (like twigs and lumber), and some sprites have no corresponding item data. There are also multiple entries for ''weeds'' and ''stone'' corresponding to different sprites, but the player can only normally obtain one ''stone'' item (index 390) and no ''weeds'' items.
 
==Big craftables==
Big craftables are objects which can be placed in the world and are two tiles tall (instead of one like objects).
 
They have their data in <samp>Data/BigCraftableInformation</samp>, their in-game sprites in <samp>TileSheets/Craftables</samp>, and their code in <samp>StardewValley.Object</samp> (with the <code>bigCraftable.Value = true</code> flag).
 
===Data format===
The big craftables data in <samp>Data/BigCraftableInformation</samp> consists of an integer→string dictionary with entries like this:
 
<syntaxhighlight lang="json">
  "19": "Oil Maker/50/-300/Crafting -9/Makes gourmet truffle oil./true/true/0/Oil Maker"

===Notes===
* Many of the items in the data asset aren't implemented in-game. They may be completely absent from the game, or they may be unused as craftables and instead appear in [[#Objects|object data]] or [[#Furniture|furniture data]].
 
==Boots==
Boots are items that can be equipped in the player's [[footwear]] slot.
 
They have their data in <samp>Data/Boots</samp>, their in-game sprites in <samp>Maps/springobjects</samp> (item sprite) and <samp>Characters/Farmer/shoeColors</samp> (shoe color), and their code in <samp>StardewValley.Objects.Boots</samp>.
 
===Data format===
The boots data in <samp>Data/Boots</samp> consists of an integer→string dictionary with entries like this:
 
<syntaxhighlight lang="json">
  "511": "Dark Boots/Made from thick black leather./250/4/2/7"
</syntaxhighlight>
 
For each entry in the data asset, the key is the item's <samp>ParentSheetIndex</samp> and the value is a slash-delimited string with these fields:


You can specify one or both fields:
<ul>
<li><samp>GeodeDrops</samp> can be set to the specific items to drop. Default none. This consists of a list of models with these fields:

|}


==Clothing==
For consistency, vanilla drops mostly use these values:
Clothing consists of cosmetic items that can be equipped in the player's [[Tailoring|pants and shirt]] slots.
* <samp>-1000</samp>: special overrides like the [[Golden Helmet|golden helmet]];
* <samp>0</samp>: normal items.
|}</li>
<li><samp>GeodeDropsDefaultItems</samp> chooses a predefined list of possible geode drops like [[clay]], [[coal]], [[Copper Ore|copper]], [[Iridium Ore|iridium]], etc. Default false.</li>
</ul>


They have their data in <samp>Data/ClothingInformation</samp>, their in-game sprites in <samp>Characters/Farmer/pants</samp> & <samp>Characters/Farmer/shirts</samp>, and their code in <samp>StardewValley.Objects.Clothing</samp>.
If both fields are specified, each geode will choose between them with an equal 50% chance. If <samp>GeodeDrops</samp> is specified but no entries match, the geode will use the <samp>GeodeDropsDefaultItems</samp> regardless of whether it's true.
|-
| <samp>ArtifactSpotChances</samp>
| ''(Optional)'' If this is an artifact (i.e. the <samp>Type</samp> field is <samp>Arch</samp>), the chance that it can be found by digging [[Artifact Spot|artifact spots]] in each location.

Hats have a hard-coded category of -95 (<samp>Hats.cs::Load</samp>)
==Unobtainable items==
The spritesheet and data have items that can't normally be found in the player inventory (like twigs and lumber), and some sprites have no corresponding item data. There are also multiple entries for ''weeds'' and ''stone'' corresponding to different sprites, but the player can only normally obtain one ''stone'' item (index 390) and no ''weeds'' items.


==Tools==
==For C# mods==
[[Tools]] are items that can be swung or used by the player to perform some effect (e.g. dig dirt, chop trees, etc).
Object-type items are represented by the <samp>StardewValley.Object</samp> type.


They have their in-game sprites in <samp>TileSheets/Tools</samp>, and their code in <samp>StardewValley.Tool</samp> and various subclasses like <samp>StardewValley.Tools.Axe</samp>.
This provides many methods to simplify common logic. Some notable examples:


===Data format===
{| class="wikitable"
Tools are currently hardcoded and can't be edited by content packs.
 
==Weapons==
[[Weapons]] are tools that can be used by the player to damage monsters.

Weapons have a hardcoded category of -98 (<samp>Object.weaponCategory</samp>).
===Slingshot notes===
* The base [[slingshot]] has <samp>ParentSheetIndex</samp> 32 in the weapon data, which increases by one for each upgrade level (up to 34 in the weapon data, though only 32 and 33 are obtainable without mods).
* Slingshot damage is [[Slingshot#Ammunition|calculated dynamically]] regardless of the weapon data.
===Mine container drops===
When the player breaks a container in [[The Mines|the mines]], there's a chance it will drop a weapon. Here's how the weapon to drop is chosen<ref>See <samp>Utility.getUncommonItemForThisMineLevel</samp> in the game code.</ref>:
<ol>
<li>Match weapons whose minimum mine level ([[#Format|field 10]]) is less than the current mine level.</li>
<li>From that list, match weapons with a probability check based on the gap between the base mine level ([[#Format|field 9]]) and current mine level. The probability is a bell curve centered on the base mine level:

|-
| 15

|-

| 25%
|-
| 25

The difference applies in both directions; for example, two weapons whose base levels are 5 below and 5 above the current level both have a 92% chance. (The probability is calculated with a [[wikipedia:Gaussian function|Gaussian function]] <code>e<sup>-(current mine level - base mine level)<sup>2</sup> / (2 * 12<sup>2</sup>)</sup></code>.)</li>
<li>Find the weapon with the smallest gap between the current and base mine levels, and add it to the list. (If the item was also selected in step 2, it has two chances to drop.)</li>
<li>From the remaining list of weapons, randomly choose one to drop.</li>

← Items

This page explains how the game stores and parses object-type item data. For items in general, see Modding:Items.

Overview

Objects are the default type for items in inventories or in the world. Depending on their data, they can be placed, picked up, eaten, sold to shops, etc.

They have item type (O) (or ItemRegistry.type_object in C# code), their data in Data/Objects, their icon sprites in Maps/springobjects or TileSheets/Objects_2 by default, and their code in StardewValley.Object. See a table of sprites and their corresponding indexes.

Data format

The object data in Data/Objects consists of a string → model lookup, where...

  • The key is the unqualified item ID.
  • The value is a model with the fields listed below.

Basic info

field purpose
Name The internal item name.
DisplayName
Description 		A tokenizable string for the item's in-game display name and description.
Type The item's general type, like Arch (artifact) or Minerals. The vanilla types are: Basic, Arch (artifact), Litter (e.g. debris), Minerals, Quest, Crafting, Fish, Cooking, Seeds, Ring, interactive, and some placeholder values like asdf.

Caution: adding custom items with the Arch type is inadvisable as it often leads to artifact spots becoming broken and not giving any items.

Note: The "Type" affects whether an item shows up in the collections menu. For example, items with Type: Cooking will show up as silhouettes in the cooked items collection menu, items with Type: Minerals will show up as silhouettes in the mineral collection menu, etc. However, the Category of the item must also be the correct number or the item will not count toward Perfection/Achievements. For example, if an item has Type: Cooking, it must also be "Category": -7 in order to count toward the "Gourmet Chef" achievement and Perfection.

Category The item category.
Price (Optional) The price when sold by the player. This is not the price when bought from a shop. Default 0.

Appearance

field purpose
Texture The asset name for the texture containing the item's sprite. Defaults to Maps/springobjects.
SpriteIndex The sprite's index within the Texture, where 0 is the top-left sprite.
ColorOverlayFromNextIndex (Optional) When drawn as a colored object, whether to apply the color to the next sprite in the spritesheet and draw that over the main sprite. If false, the color is applied to the main sprite instead. Default false.

Edibility

field purpose
Edibility (Optional) A numeric value that determines how much energy (edibility × 2.5) and health (edibility × 1.125) is restored when this item is eaten. An item with an edibility of -300 can't be eaten, values from -299 to -1 reduce health and energy, and zero can be eaten but doesn't change health/energy. Default -300.
IsDrink (Optional) Whether to drink the item instead of eating it. Default false.
Buffs (Optional) The buffs to apply to the player when this item is eaten, if any. Default none.

This consists of a list of models with these fields:

field purpose
Id The unique string ID for this entry within the list.
Duration (Optional if BuffId is set) The buff duration measured in in-game minutes. This can be set to -2 for a buff that should last for the rest of the day.
BuffId (Optional) The unique ID of a buff from Data/Buffs to apply, or null to ignore Data/Buffs and set the ID to food or drink depending on the item's IsDrink field.

If a buff from Data/Buffs is applied and you also specify other fields, here's how the buff data is combined:

field result
Duration
IconTexture
IconSpriteIndex
GlowColor 		If specified, the value in Data/Objects is used instead of the one in Data/Buffs. If omitted, defaults to the value from Data/Buffs.
CustomAttributes The values from both entries are combined (e.g. +1 speed in Data/Objects and +1 speed in Data/Buffs results in +2 speed).
IsDebuff The value in Data/Objects is used.
IsDebuff (Optional) Whether this buff counts as a debuff, so its duration should be halved when wearing a Sturdy Ring. Default false.
IconTexture (Optional) The asset name for the icon texture to load. This must contain one or more 16x16 icons in a grid of any size. If omitted, the game will draw a default icon based on the BuffId and CustomAttributes fields.
IconSpriteIndex (Optional) The buff's icon index within the IconTexture, where 0 is the top-left icon. Default 0.
GlowColor (Optional) The glow color to apply to the player. See color format. Default none.
CustomAttributes The custom buff attributes to apply, if any.

This consists of a model with any combination of these fields:

field purpose
CombatLevel
FarmingLevel
FishingLevel
ForagingLevel
LuckLevel
MiningLevel 		(Optional) An amount applied to the matching skill level while the buff is active. This can be negative for a debuff. Default 0.
Attack
AttackMultiplier
CriticalChanceMultiplier
CriticalPowerMultiplier
Defense
Immunity
KnockbackMultiplier
MagneticRadius
MaxStamina
Speed
WeaponPrecisionMultiplier
WeaponSpeedMultiplier 		(Optional) An amount applied to the player's attack, critical chance and critical power, defense, immunity, knockback (i.e. weight), magnetic radius, maximum stamina, speed, or weapon precision/speed while the buff is active. This can be negative for a debuff. Default 0.
CustomFields (Optional) The custom fields for this entry.

Geodes & artifact spots

field purpose
GeodeDrops
GeodeDropsDefaultItems 		(Optional) The items that can be dropped when breaking open this item as a geode. Specifying either or both fields automatically enables geode behavior for this item.

You can specify one or both fields:

  • GeodeDrops can be set to the specific items to drop. Default none. This consists of a list of models with these fields:
    field purpose
    common fields See item spawn fields for the generic item fields supported by geode drops.

    If set to an item query which returns multiple items, one of them will be selected at random.

    Chance (Optional) The probability that the item will be dropped if the other fields match, as a decimal value between 0 (never) and 1 (always). Default 1.
    SetFlagOnPickup (Optional) The mail flag to set for the current player when this drop is picked up.
    Precedence (Optional) The order in which this entry should be checked, where lower values are checked first. This can be a negative value. Geode drops with the same precedence are checked in the order listed. Default 0.

    For consistency, vanilla drops mostly use these values:

    • -1000: special overrides like the golden helmet;
    • 0: normal items.
  • GeodeDropsDefaultItems chooses a predefined list of possible geode drops like clay, coal, copper, iridium, etc. Default false.

If both fields are specified, each geode will choose between them with an equal 50% chance. If GeodeDrops is specified but no entries match, the geode will use the GeodeDropsDefaultItems regardless of whether it's true.

ArtifactSpotChances (Optional) If this is an artifact (i.e. the Type field is Arch), the chance that it can be found by digging artifact spots in each location.

This consists of a string → model lookup, where:

  • the key is the internal location name;
  • the value is the probability the item will spawn if checked, as a decimal value between 0 (never) and 1 (always).

Context tags & exclusions

field purpose
ContextTags (Optional) The custom context tags to add for this item (in addition to the tags added automatically based on the other object data). This is formatted as a list; for example: 
"ContextTags": [ "color_yellow", "fish_ocean", "fish_upright", "season_summer" ]
CanBeGivenAsGift (Optional) Whether this item can be gifted to NPCs. Default true.
CanBeTrashed (Optional) Whether this item can be trashed from the player's inventory. Also affects whether the item can be shipped but not whether it can be sold to shops. Default true.
ExcludeFromRandomSale (Optional) Whether to exclude this item from shops when selecting random items to sell. Default false.
ExcludeFromFishingCollection
ExcludeFromShippingCollection 		(Optional) Whether to exclude this item from the fishing/shipping collection and their respective effect on the perfection score. Default false, in which case the normal requirements apply (e.g., artifacts are always excluded from the shipping collection).

Advanced

field purpose
CustomFields (Optional) The custom fields for this entry.

Unobtainable items

The spritesheet and data have items that can't normally be found in the player inventory (like twigs and lumber), and some sprites have no corresponding item data. There are also multiple entries for weeds and stone corresponding to different sprites, but the player can only normally obtain one stone item (index 390) and no weeds items.

For C# mods

Object-type items are represented by the StardewValley.Object type.

This provides many methods to simplify common logic. Some notable examples:

method effect
Object.GetRadiusForScarecrow() The tile radius that Object protects as a scarecrow. Default behavior: Checks for the value in the crow_scare_radius_<radius> context tag if applicable, then defaults to 17 if the internal name contains "Deluxe" and 9 otherwise. Can be patched to support custom scarecrows.
Object.IsBar() Whether the item is a copper bar, iron bar, gold bar, iridium bar, or radioactive bar.
Object.IsBreakableStone() Whether the item is a stone debris item which can be broken by a pickaxe.
Object.IsFence() Whether the item is a fence.
Object.IsFruitTreeSapling() Whether the item is a fruit tree sapling. This checks the Data\fruitTrees keys, so it works with custom fruit trees too.
Object.IsHeldOverHead() Whether the player is shown holding up the item when it's selected in their toolbar. Default true (except for furniture).
Object.IsIncubator() Whether the item can incubate farm animal eggs when placed in a building.
Object.IsScarecrow() Whether the item is a scarecrow. Default: true if the object has the crow_scare context tag. Otherwise, returns whether the object's internal name contains "arecrow". Can be patched to support custom scarecrows.
Object.IsTapper() Whether the item is a tapper or heavy tapper.
Object.IsTeaSapling() Whether the item is a tea sapling.
Object.IsTwig() Whether the item is a twig debris item.
Object.IsWeeds() Whether the item is a weed debris item.
