| ==Mod APIs==
| | [[es:Modding:Guía del Modder/APIs]] |
| ===Content packs===
| | [[ru:Модификации:Руководство мододела/API]] |
| A content pack is a sub-mod containing files your mod can read. These are installed just like a regular SMAPI mod, but don't do anything on their own. These must specify your mod in their <tt>manifest.json</tt>. See [[Modding:Content packs]] for more info about content packs.
| | [[tr:Modlama:Mod Rehberi/API'ler]] |
| | | [[zh:模组:制作指南/APIs]] |
| SMAPI provides a method to get content packs loaded for your mod, and each content pack has an API you can use to read its files:
| |
| <source lang="c#">
| |
| foreach(IContentPack contentPack in this.Helper.GetContentPacks())
| |
| {
| |
| // read content pack manifest
| |
| this.Monitor.Log($"Reading content pack: {contentPack.Manifest.Name} {contentPack.Manifest.Version}");
| |
| | |
| // read a JSON file
| |
| YourDataFile data = contentPack.ReadJsonFile<YourDataFile>("content.json");
| |
| | |
| // load an asset or image
| |
| Texture2D image = contentPack.LoadAsset<Texture2D>("image.png");
| |
| }
| |
| </source>
| |
| | |
| ===Logging===
| |
| Your mod can write messages to the console window and log file using the monitor. For example, this code:
| |
| | |
| <source lang="c#">
| |
| this.Monitor.Log("a trace message", LogLevel.Trace);
| |
| this.Monitor.Log("a debug message", LogLevel.Debug);
| |
| this.Monitor.Log("an info message", LogLevel.Info);
| |
| this.Monitor.Log("a warning message", LogLevel.Warn);
| |
| this.Monitor.Log("an error message", LogLevel.Error);
| |
| </source>
| |
| | |
| will log something like this:
| |
| | |
| <div style="font-family: monospace;">
| |
| <span style="color:#666;">[18:00:00 TRACE Mod Name] a trace message</span><br />
| |
| <span style="color:#666;">[18:00:00 DEBUG Mod Name] a debug message</span><br />
| |
| <span style="color:black;">[18:00:00 INFO Mod Name] an info message</span><br />
| |
| <span style="color:darkorange;">[18:00:00 WARN Mod Name] a warning message</span><br />
| |
| <span style="color:red;">[18:00:00 ERROR Mod Name] an error message</span>
| |
| </div>
| |
| | |
| Note that <tt>LogLevel.Trace</tt> messages won't appear in the console window by default, they'll only be written to the log file. Trace messages are for troubleshooting details that are useful when someone sends you their error log, but which the player normally doesn't need to see. (You can see trace messages in the console if you install the "SMAPI for developers" version.)
| |
| | |
| ===Reflection===
| |
| SMAPI provides an API for robustly accessing fields, properties, or methods you otherwise couldn't access, such as private fields. You can use it from <tt>helper.Reflection</tt> in your entry method, or <tt>this.Helper.Reflection</tt> elsewhere in your entry class.
| |
| | |
| Here are a few examples of what this lets you do:
| |
| | |
| <source lang="c#">
| |
| // did you pet your pet today?
| |
| bool wasPet = this.Helper.Reflection.GetField<bool>(pet, "wasPetToday").GetValue();
| |
| | |
| // what is the spirit forecast today?
| |
| string forecast = this.Helper.Reflection
| |
| .GetMethod(new TV(), "getFortuneForecast")
| |
| .Invoke<string>();
| |
| | |
| // randomise the mines
| |
| if(Game1.currentLocation is MineShaft)
| |
| this.Helper.Reflection.GetField<Random>(Game1.currentLocation, "mineRandom").SetValue(new Random());
| |
| </source>
| |
| | |
| This works with static or instance fields/methods, caches the reflection to improve performance, and will throw useful errors automatically when reflection fails.
| |
| | |
| If you need to do more, you can switch to [https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/reflection C#'s underlying reflection API]:
| |
| | |
| <source lang="c#">
| |
| FieldInfo field = this.Helper.Reflection.GetField<string>(…).FieldInfo;
| |
| MethodInfo method = this.Helper.Reflection.GetMethod(…).MethodInfo;
| |
| </source>
| |
| | |
| ===Mod registry===
| |
| Your mod can get information about loaded mods, or check if a particular mod is loaded. (All mods are loaded by the time your mod's <tt>Entry(…)</tt> method is called.)
| |
| | |
| <source lang="c#">
| |
| // check if a mod is loaded
| |
| bool isLoaded = this.Helper.ModRegistry.IsLoaded("UniqueModID");
| |
| | |
| // get manifest info for a mod (name, description, version, etc.)
| |
| IManifest manifest = this.Helper.ModRegistry.Get("UniqueModID");
| |
| | |
| // get manifest info for all loaded mods
| |
| foreach(IManifest manifest in this.Helper.ModRegistry.GetAll()) { … }
| |
| </source>
| |
| | |
| ===Multiplayer===
| |
| The multiplayer API provides methods to support modding in a multiplayer context:
| |
| <source lang="c#">
| |
| // get a unique multiplayer ID (e.g. for animal IDs)
| |
| int uniqueID = this.Helper.Multiplayer.GetNewID();
| |
| | |
| // get the locations being sync'd from the main player
| |
| foreach (GameLocation location in this.Helper.Multiplayer.GetActiveLocations())
| |
| </source>
| |
| | |
| ===Translation===
| |
| The translation API lets you translate your mod into the player's current language, accounting for locale fallback automatically (e.g. if a translation isn't available in <tt>pt-BR.json</tt>, SMAPI will check <tt>pt.json</tt> and <tt>default.json</tt>). Translations can be a simple string, or they can include tokens to inject values into the translation.
| |
| | |
| <dl>
| |
| <dt>File structure</dt>
| |
| <dd>SMAPI reads translations from JSON files in a structure like this:
| |
| <pre>
| |
| YourMod/
| |
| i18n/
| |
| default.json
| |
| es.json
| |
| pt.json
| |
| manifest.json
| |
| YourMod.dll
| |
| </pre>
| |
| | |
| The <tt>default.json</tt> file should contain a flat key→value lookup with your default text. Each key is case-insensitive, and can contain alphanumeric, underscore, hyphen, and dot characters. Feel free to add JavaScript comments to organise or document your translations. For example:
| |
| <source lang="javascript">
| |
| {
| |
| // example translations
| |
| "item-type.label": "Item type",
| |
| "item-type.fruit-tree": "{{fruitName}} tree",
| |
| }
| |
| </source>
| |
| | |
| You can then add translation files for each language you want to support, by copying the <tt>default.json</tt> file and translating its values. Each translation file should have one of these file names:
| |
| | |
| {| class="wikitable"
| |
| |-
| |
| ! Language
| |
| ! File name
| |
| |-
| |
| | Chinese
| |
| | <tt>zh.json</tt>
| |
| |-
| |
| | German
| |
| | <tt>de.json</tt>
| |
| |-
| |
| | Japanese
| |
| | <tt>ja.json</tt>
| |
| |-
| |
| | Portuguese
| |
| | <tt>pt.json</tt>
| |
| |-
| |
| | Russian
| |
| | <tt>ru.json</tt>
| |
| |-
| |
| | Spanish
| |
| | <tt>es.json</tt>
| |
| |}</dd>
| |
| | |
| <dt>Reading translations</dt>
| |
| <dd>Once your i18n files are set up, you can read translations for the current locale:
| |
| <source lang="c#">
| |
| // read a simple translation
| |
| string label = helper.Translation.Get("item-type.label");
| |
| | |
| // read a translation which uses tokens (accepts an anonymous object, dictionary, or model)
| |
| string text = helper.Translation.Get("item-type.fruit-tree", new { fruitName = "apple" });
| |
| </source>
| |
| | |
| The <tt>helper.Translate(…)</tt> method returns a fluent interface — you can keep calling methods on its return value to customise the translation. (See IntelliSense for a description of the available methods.) To get the text, simply assign it to a string:
| |
| <source lang="c#">
| |
| // use fluent chain
| |
| string text = helper.Translate(key).Tokens(tokens).Tokens(moreTokens).Assert();
| |
| </source>
| |
| | |
| If your code has a lot of translation calls, you can make it less verbose by aliasing the translation helper:
| |
| <source lang="c#">
| |
| var i18n = helper.Translation;
| |
| | |
| i18n.Get("item-type.fruit-tree", new { fruitName = i18n.Get("apple") });
| |
| </source></dd>
| |
| | |
| <dt>Tips for translators</dt>
| |
| <dd>
| |
| * Save i18n files with UTF-8 encoding to avoid broken symbols in-game.
| |
| * Type <code>reload_i18n</code> into the SMAPI console and hit enter to reload translations without exiting the game. (If a mod internally cached a translation, it may not be updated.)
| |
| </dd>
| |
| </dl>
