using namespace emscripten;
 
 
// This file uses emscripten's embind to bind C++ classes,
// C structures, functions, enums, and contents into JavaScript,
// so you can even subclass C++ classes in JavaScript,
// for implementing plugins and user interfaces.
//
// Wrapping the entire Micropolis class from the Micropolis (open-source
// version of SimCity) code into Emscripten for JavaScript access is a
// large and complex task, mainly due to the size and complexity of the
// class. The class encompasses almost every aspect of the simulation,
// including map generation, simulation logic, user interface
// interactions, and more.
//
// Strategy for Wrapping
// 
// 1. Core Simulation Logic: Focus on the core simulation aspects, such
//    as the methods to run the simulation, update game states, and handle
//    user inputs (like building tools and disaster simulations). This is
//    crucial for any gameplay functionality.
// 
// 2. Memory and Performance Considerations: JavaScript and WebAssembly
//    run in a browser context, which can have memory limitations and
//    performance constraints. Carefully manage memory allocation,
//    especially when dealing with the game's map and various buffers.
// 
// 3. Direct Memory Access: Provide JavaScript access to critical game
//    data structures like the map buffer for efficient reading and
//    writing. This can be done using Emscripten's heap access functions
//    (HEAP8, HEAP16, HEAP32, etc.).
// 
// 4. User Interface and Rendering: This part might not be necessary to
//    wrap, as modern web technologies (HTML, CSS, WebGL) can be used for
//    UI. However, providing some hooks for game state (like score, budget,
//    etc.) to JavaScript might be helpful.
// 
// 5. Callbacks and Interactivity: Ensure that key game events and
//    callbacks are exposed to JavaScript, allowing for interactive and
//    responsive gameplay.
// 
// 6. Optimizations: Where possible, optimize C++ code for WebAssembly,
//    focusing on critical paths in the simulation loop.
// 
// Decisions and Explanations
//
// - Excluded Elements:
//       
//     - Low-level rendering or platform-specific code, as this can be
//       handled more efficiently with web technologies.
//       
//     - Parts of the code that handle file I/O directly, as file access
//       in a web context is typically handled differently (e.g., using
//       browser APIs or server-side support).
//       
//     - Any networking or multiplayer code, as web-based
//       implementations would differ significantly from desktop-based
//       network code.
//
// - Included Elements:
//       
//     - Core game mechanics, such as map generation, zone simulation
//       (residential, commercial, industrial), disaster simulation, and
//       basic utilities.
//       
//     - Game state management, including budgeting, scoring, and city
//       evaluation.
//       
//     - Direct memory access to critical structures like the map
//       buffer, allowing efficient manipulation from JavaScript.
// 
//     - Essential callbacks and event handling mechanisms to ensure
//       interactivity.
//
// Conclusion
// 
// Given the complexity and size of the Micropolis class, wrapping the
// entire class directly is impractical. However, focusing on key areas
// essential for gameplay and providing efficient interfaces for
// critical data structures can create a functional and interactive city
// simulation in a web context. Further optimizations and adjustments
// would likely be needed based on testing and specific requirements of
// the web implementation.
// 
// Implementation Notes
//
// The enum_, class_, constructor, function, and property functions
// from the emscripten namespace are used to specify how C++
// constructs should be exposed to JavaScript. You can use these to
// control which parts of your code are accessible and how they should
// be used from JavaScript.
//
// I've made some assumptions here:
//
// The types MapValue and MapTile are simple types (like integers or
// floats). If they are complex types, they would need their own
// bindings.
//
// I'm assuming that the copy constructor and copy assignment
// operator for the Position class are correctly implemented. If
// they aren't, then the Position object may not behave as expected
// in JavaScript.
// 
// Micropolis Binding Design
//
// The Micropolis interface organizes the Micropolis class header into
// categories of functions that are relevant for interaction with the
// JavaScript user interface, scripts, or plugins. The aim is to expose
// functions that could help in monitoring and controlling game state
// effectively.

// 
// These exposed functions provide a comprehensive interface for
// scripting, plugins, and user interactions through JavaScript. The
// exposed set of functions includes random number generation,
// simulation control mechanisms, UI-triggered actions like budget
// updates, along with essential gameplay mechanics. The private section
// continues to encapsulate internal simulation details and complex data
// management routines integral to the game's core mechanics.
