# EaglerForge ModAPI Documentation The EaglerForge ModAPI is housed in a global JavaScript object stored on `globalThis`, called `ModAPI` or `PluginAPI`. (both are identical) ### Important Notice! From people used to the doc prior to EaglerForgeInjector, now, when you see something like `ModAPI.world`'s type is `World`, that literally means it is identical to an instance of `net.minecraft.world.World` from java. For easier modding, here are some online javadocs, that explain properties from each individual method and proerty of every 1.8 class: https://nurmarvin.github.io/Minecraft-1.8-JavaDocs/overview-summary.html - Javadoc for vanilla 1.8 https://eaglerreborn.github.io/javadoc/ - EaglerReborn (EF precursor) javadoc, for EaglercraftX u17 (missing serverside classes, this version didn't have singleplayer) An up-to-date javadoc for EaglercraftX is coming soon, in the meanwhile, I recommend modding with a local EaglercraftX workspace, so you can inspect the contents of each class. Additionally, when you se that something like `ModAPI.mcinstance` is `Raw` this means that it has a lot of TeaVM nonsense like '$' prefixes before everything, as well has making it difficult to call the objects methods. ### Global ModAPI Object: The global object has the following properties: - `ModAPI.player: EntityPlayerSP` - Only accessible after `ModAPI.require("player")` is called, this is the local player entity. It is regenerated every time the `update` event is called. - `ModAPI.world: WorldClient` - Only accessible after `ModAPI.require("world")` is called, this is the client-side world. It is regenerated every time the `update` event is called. - `ModAPI.network: NetHandlerPlayClient` - Only accessible after `ModAPI.require("network")` is called, this is the client's networking handler. It is regenerated every time the `update` event is called. - `ModAPI.settings: GameSettings` - This is the Minecraft client's settings. It is generated upon init. - `ModAPI.items: Map` - This is a key-value dictionary of all of the items in the game. It is generated upon init from the static variables of the `Items` class. - For example, to access the item class for `acacia_door`, you can use `ModAPI.items["acacia_door"]` - `ModAPI.blocks: Map` - This is a key-value dictionary of all of the blocks in the game. It is generated upon init from the static variables of the `Blocks` class. - For example, to access the block class for `bedrock`, you can use `ModAPI.blocks["bedrock"]` - `ModAPI.materials: Map` - This is a key-value dictionary of all of the blocks in the game. It is generated upon init from the static variables of the `Material` class. - For example, to access the material class for `portal`, you can use `ModAPI.materials["portal"]` - `ModAPI.enchantments: Map` - This is a key-value dictionary of all of the enchantments in the game. It is generated upon init from the static variables of the `Enchantment` class. - For example, to access the enchantment class for `knockback`, you can use `ModAPI.enchantments["knockback"]` - As the enchantment class has other static variables, `Object.keys` will also return non-enchantment keys such as `enchantmentsBookList`. - `ModAPI.blockSounds: Map` (1.12 only) - This is a key-value dictionary of `SoundType`s. Used in `.setSoundType(soundType)` when registering custom blocks in 1.12. - `ModAPI.minecraft: Minecraft` - This is the minecraft instance for the client, generated upon init. - It can also be accessed using `ModAPI.mc` - `ModAPI.mcinstance: Raw` - This is the raw minecraft instance for the client, generated upon init. - It can also be accessed using `ModAPI.javaClient` - It can also be accessed using `ModAPI.minecraft.getRef()` - It can also be accessed using `Minecraft` - Only here for compatibility - `ModAPI.server: MinecraftServer` - This is the dedicated minecraft server in the service worker, generated when the `serverstart`. - It can only be accessed in the dedicated server's context. (See `ModAPI.dedicatedServer`) - It can also be accessed using `ModAPI.serverInstance` - `ModAPI.rawServer: MinecraftServer` - This is the dedicated minecraft server in the service worker, generated when the `serverstart` event is fired. - It can only be accessed in the dedicated server's context. (See `ModAPI.dedicatedServer`) - It can also be accessed using `ModAPI.server.getRef()` - `ModAPI.hooks` - This is the internal hooking map for ModAPI and can be used to patch, intercept, or rewrite internal functions, and more. - More: [HooksDocumentation](hooks.md) - `ModAPI.util` - This contains utilities for using `ModAPI.hooks`, `ModAPI.reflect`, and more. - More: [UtilDocumentation](utils.md) - `ModAPI.reflect` - This is a wrapper around `ModAPI.hooks`, `ModAPI.hooks._teavm` and `ModAPI.hooks._classMap` that makes accessing and using internal java classes in mods much easier. - More: [ReflectDocumentation](reflect.md) - `ModAPI.dedicatedServer` - This object is used to push code for use in the dedicated server. - Once the dedicated server worker has started, it is unuseable. - More: [DedicatedServerDocumentation](dedicatedserver.md) - `ModAPI.meta` - This module is used to register metadata for mods such as their title, credits, icon and description. - More: [MetaDocumentation](meta.md) - `ModAPI.array` - This module is used to interact and create arrays easily. - More: [ArrayDocumentation](array.md) - `ModAPI.keygen` - This module is used to get IDs for registering blocks and items without hardcoding an ID. - More: [KeygenDocumentation](keygen.md) - `ModAPI.resolution` - This module is used to query information about GUI dimensions, to make drawing to the screen easier, generated when the `frame` event is fired. - Deprecated alias (please do not use): `ModAPI.ScaledResolution` - More: [ArrayDocumentation](array.md) - `ModAPI.version: String` - The version of ModAPI. - `ModAPI.is_1_12: Boolean` - Property defining wether or not ModAPI thinks the current version is 1.12-based. - `ModAPI.isServer: Boolean` - Property defining wether or not ModAPI thinks it is running on the dedicated server. - `ModAPI.flavour: String` - The flavour of ModAPI. Hardcoded to be `"injector"`. The ModAPI object has the following methods: - `addEventListener(eventName: String, callback: Function) : void` - More: [EventDocumentation](events.md) - `require(componentName: String) : void` - Import required modules, such as `player` and `network`. - Usage: `ModAPI.require("module")` - `displayToChat(message: String) : void` - Displays client-side message to user's ingame chat gui. - Usage: `ModAPI.displayToChat("Hello World.")` - `clickMouse() : void` - Triggers a left click ingame. - `rightClickMouse() : void` - Triggers a right click ingame. - `getFPS() : int` - Gets the frames per second of the game - `promisify(asyncJavaMethod: Method | Constructor) : PromisifiedJavaRunner` - Allows running java methods that are @Async/@Async dependent. - More: [PromisifyDocumentation](promisify.md) - `addCredit(category: String, contributor: String, contents: String)` - Lets you easily add credits to Eaglercraft's credits.txt - eg: `ModAPI.addCredit("My Cool Mod", "Username", " - Coded the mod\n - Wrote somne credits")` ## Handling strings, numbers and booleans to and from java. Java strings and JavaScript strings are not the same. Calling a method like this: `ModAPI.player.sendChatMessage("hello world")`, will not work, as you are running a Java method with a JavaScript string. To convert a JS string to a Java string, use `ModAPI.util.str(yourString)`. For example, the correct version of the above example is `ModAPI.player.sendChatMessage(ModAPI.util.str("hello world"))`. This problem is automatically mitigated on a few functions, namely `ModAPI.displayToChat()`. --- Java numbers and JavaScript numbers are stored the same way, with no problems with having to cast, like with strings. This is why you can simply do something like `ModAPI.player.motionY = 99999`, without having to do any conversion. --- Booleans in Java are stored as a number, where `1` means `true` and `0` means `false`. There are no functions for converting inbetween these, because it is very easy to do so (unlike strings). To convert a javascript boolean into a java boolean simply multiply you boolean by 1. Eg: ```javascript var myBool = true; console.log(myBool * 1); // logs '1' var myBool = false; console.log(myBool * 1); // logs '0' ``` Better yet, if you need to use booleans very often, just store them as numbers directly in javascript. JavaScript if statements already recognise `0` as false, so something like: ```javascript var condition = 0; if (condition) { console.log("yes"); } else { console.log("no"); } // outputs 'no' ``` will work out of the box. ## Accessing raw data In ModAPI's architecture, when you request an object like `ModAPI.player`, instead of giving you `ModAPI.mcinstance.$thePlayer`, it will return a `TeaVM_to_Recursive_BaseData_ProxyConf` proxy. These automatically remove the `$` prefixes, make instance methods run with the actaul object, and a variety other features. However, when calling methods via `ModAPI.hooks`, `ModAPI.reflect`, or even just running a method that takes in object arguments on something like `ModAPI.player`, passing in these ModAPI proxies will cause an error. To pass in raw java data simply call `getRef()` on the proxy which will return the raw, unmodified version of it. For example, take the method `setRenderViewEntity()` on `ModAPI.mcinstance`. Instead of passing an entity from `ModAPI.world.loadedEntityList.get(index)` directly, you need to use `ModAPI.world.loadedEntityList.get(index).getRef()`. Demo code: ```javascript var entityIndex = 1; //Index of the entity to look for. 0 means first, which is usually the player, so 1 is usually a natural entity. ModAPI.mc.setRenderViewEntity(ModAPI.world.loadedEntityList.get(entityIndex).getRef()); ``` Note that an entry for `getRef` will not appear from `Object.keys` and similar web APIs. ## Checking if an object is a proxy All proxied objects have a property `isModProxy` which is equal to true. Note that an entry for `isModProxy` will not appear from `Object.keys` and similar web APIs. ## Corrective Proxies By default, accessing a global like `ModAPI.player` will return a proxy to the original player that removes $ prefixes, as well as making instance methods callable. TeaVM has a quirk where it adds numerical suffixes to some properties. For example `ModAPI.player.inGround0` instead of `ModAPI.player.inGround`. As this is a large issue due to these suffixes changing for every eaglercraft update, you can now bypass this by obtaining a corrective version of `ModAPI.player`, using `ModAPI.player.getCorrective()`. For example: ```javascript ModAPI.player.inGround //returns undefined ModAPI.player.inGround0 //returns 1 or 0, the correct value ModAPI.player.isCorrective() //returns false var correctedPlayer = ModAPI.player.getCorrective(); correctedPlayer.inGround //returns 1 or 0, the correct value correctedPlayer.inGround0 //returns 1 or 0, the correct value correctedPlayer.isCorrective() //returns true ``` You can check if an object is corrective using `.isCorrective()`; Accessing children of a corrective object will also make them corrective. `correctedPlayer.fishEntity.isCorrective(); //true`
