-## A userscript that allows eaglercraft to run on mobile devices
-To-do
-- [ ] Gamepad support
-- [ ] Cancel button for file upload
-- [ ] Styling for file upload
-- [ ] Back button for Kiwi browser?
-- [ ] Fix keyboard input for Android devices
 
-Implemented
 
-- [x] Fake pointerlock API (tricks the client into loading)
+![](https://img.shields.io/badge/Github-v3.0.1-blue?style=flat-square&logo=github&logoColor=white&label=GitHub&color=181717)
-- [x] Fake fullscreen API (so that selecting full screen doesn't crash the client)
+[![](https://img.shields.io/github/license/FlamedDogo99/EaglerMobile?style=flat-square)](https://github.com/FlamedDogo99/EaglerMobile/blob/master/LICENSE)
-- [x] Custom upload button for files (because safari is a pain with button clicks)
+
-- [x] Fake mousemove events (Allows touch and drag to simulate mouse movement)
+## About
-- [x] Fake cursor scroll events (Allows scrolling through hotbar and in menus)
+
-- [x] On-screen controls (Movement, block placement/removal/picking, inventory, item dropping, keyboard, and exiting keys)
+Eagler Mobile brings new functionality and benefits for the EaglerCraft web client by providing mobile-friendly touch controls, keyboard access, and other settings configirable through the EaglerCraft client. 
-- [x] Styling for html, body, and canvas (So that the canvas doesn't ignore the navigation bars for viewport sizing)
+
-- [x] Strafe buttons when holding forward
+<div align="center">
-- [x] Crouch lock on hold
+
-- [x] Re-orginize button layout
+![Eagler Mobile Screenshot](images/preview.png)
-- [x] Redo the display button functions
+
-- [x] Sprint button (sperate from double tapping forward)
+</div>
+
+## Installation
+
+The easiest way to use Eagler Mobile is to use a userscript application such as Greasemonkey. That being said, because Eagler Mobile is plain JavaScript you can easily deploy it in other ways as well. For instance we've included `eaglermobile.ef.js` which can be run as a mod on [EaglerForge](https://github.com/eaglerforge/EaglerForge).
+
+If you want to download the source, no building is required. The best way to download the source is with Git:
+
+```sh
+git clone https://github.com/FlamedDogo99/EaglerMobile.git
+```

+
+
+### Features and documentation
+#### Fake API's
+- Pointerlock methods such as `Element.prototype.requestPointerLock`, `document.pointerLockElement`, and `document.exitPointerLock` are replaced with vanilla JavaScript that mimics pointerlock functionality. This allows the EaglerCraft client to load.
+- Fullscreen methods such as `Element.prototype.requestFullscreen`, `document.fullscreenElement`, and `document.exitFullscreen` are replaced with vanilla JavaScript that mimics fullscreen functionality. This fixes a crash due with viewport dimensions.
+
+#### Keyboard Events
+- The EaglerCraft client captures keypress through a `keydown` event listener. Because Android devices currently have an issue with `keydown` and `keyup` events, Eagler Mobile dynamically toggles between capturing `keydown` and `input` events. The state is saved in window.keyboardFix, and is toggled if a faulty keyboard event is detected.
+- To dispatch keyboard events, Eagler Mobile requires the use of the `keyEvent` function, in order to maintain functionality for `input` event listeners. For example, typing an uppercase `h` in the chat is as simple as:
+  ```js
+  keyEvent("shift", "keydown"); 
+  keyEvent("h", "keydown");
+  ```
+#### Mobile controls
+- Eagler Mobile controls can either be shown in-game or in-menu. When creating a an element you can achieve this simply by either adding the `inGame` or `inMenu` class.
+- Simple gesture controls such as scrolling, single pressing, and long pressing have been implemented, however there are currently no functions provided to easily bring this functionality to other elements.
+
+#### File uploads
+- On MacOS and iOS safari, the EaglerCraft client's implementation of triggering the file selection dialog does not work. A rudimentary fix has been added for now.
+

+
+Eagler Mobile is licensed under the terms of the [Apache License, Version 2.0](https://github.com/FlamedDogo99/EaglerMobile/blob/main/LICENSE).
+
+## Intended future features
+- [ ] **Gamepad support**: Mapping gamepad inputs to `keyEvent`, `wheelEvent` and `mouseEvent` functions, and implenting a controllable fake cursor for menus.
+- [ ] **File upload improvements**: Adding a cancel button and improving the styling
+- [ ] **Dynamic enable and disable of features**: Seperating gamepad controls, touch controls, pointerlock fix, and upload fix into seperate functions which can be enabled and disabled by the user
