     8→
     9→| Area | Decision | Rationale |
    10→|------|----------|-----------|
    11→| Renderer | OpenGL | Smooth rotation, additive blending, performance headroom, console-portable |
    12→| Audio | TBD (miniaudio or SoLoud) | Need pitch shifting; SDL_mixer insufficient |
    13→| Physics | Box2D 3.1 | Already used, true ball-to-ball collisions needed |
    14→| Scripting | Lua 5.4 + YueScript | Build-time compilation with `-r` flag for line numbers |
    15→| Timestep | Fixed 120Hz physics, 60Hz render | Decoupled for pixel-perfect visuals with responsive input |
    16→| Resolution | Per-game configurable | 480×270, 640×360, or custom; aspect-ratio scaling with letterboxing |
    17→| C Structure | Single anchor.c | Monolithic file, easier navigation |
    18→| Resources | Live forever | Games are small enough; no unloading needed |
    19→| Linking | Static | No DLLs; SDL2, Lua, audio all compiled in |
    20→| Distribution | Single executable | Zip-append for game content, extractable by modders |

Here's what I found about the Heaps.io (hxd) input API documentation for keyboard, mouse, and gamepad:

## Heaps.io Input API Overview

The Heaps.io API includes the `hxd` package which contains cross-platform classes and a complete resource loading and management framework. This includes mouse, keyboard and gamepad support.

### Keyboard Input (`hxd.Key`)

Keyboard events can be captured using the global event. Check if the `event.kind` is `EKeyDown` or `EKeyUp`. You can also use the static functions `hxd.Key.isPressed`, `hxd.Key.isDown` and `hxd.Key.isReleased`.(no content)Mouse wheel does not have an off signal, and should be checked only through the `isPressed` method. Note that there may be multiple wheel scrolls between 2 frames, so it is recommended to directly listen to wheel events which also provide OS-generated wheel delta value.

### Mouse Input (`h2d.Interactive`)

Making objects interactive (with the mouse) is done by creating a `h2d.Interactive` instance. You provide it with an interaction area and attach it to a sprite. This can be used to implement buttons for the UI, but also for any other object that responds to being clicked or hovered over.

Key Interactive events include:

- **onOver**: Sent when mouse enters Interactive hitbox area.
- **onOut**: Sent when mouse exits Interactive hitbox area.
- **onPush**: Sent when Interactive is pressed by the user.
- **onClick**: Sent when the Interactive is clicked by the user. Can be prevented by calling `Interactive.preventClick` during or after `Interactive.onPush` event.(no content)By default, Interactive only reacts to primary (left) mouse button for actions.(no content)When enabled, `enableRightButton` allows interacting with secondary mouse buttons (right button/wheel) to cause onPush, onClick, onRelease and onReleaseOutside callbacks.

### Mouse Mode (`hxd.impl.MouseMode`)

The mouse movement input handling mode includes "Absolute" - the default mouse movement mode that causes EMove events in window coordinates.(no content)Relative mouse movement mode hides the mouse cursor and invokes callbacks with relative mouse movement instead of EMove events. During Relative mouse mode the window mouse position is not updated.

### Gamepad Input (`hxd.Pad`)

Here's what I found about GDevelop's input conditions for keyboard, mouse, touch, and gamepad from the official documentation:

## Mouse and Touch

"The cursor/touch is on an object" condition checks if the mouse cursor or a screen touch is over an object. This condition can be used with "Mouse button pressed" or "Mouse button released" to check if the object is clicked or tapped.(no content)Conditions, actions and expressions are available to handle either the mouse or touches on a touchscreen, including cursor position, mouse wheel, mouse buttons, touch positions, started/ended touches, etc. By default, conditions related to the mouse will also handle touches, making it easier to handle both in your game. You can disable this behavior if you want to handle them separately.(no content)When activated, any touch made on a touchscreen will also move the mouse cursor. When deactivated, mouse and touch positions will be completely independent. By default, this is activated so you can simply use the mouse conditions to also support touchscreens. If you want multitouch and differentiate mouse movement and touches, you can deactivate it.

Key conditions include:

- Mouse button pressed or touch held - checks if the specified mouse button is pressed or if a touch is in contact with the screen.
- A new touch has started - checks if a touch has just started or the mouse left button has been pressed on this frame. The touch identifiers can be accessed using StartedTouchOrMouseId() and StartedTouchOrMouseCount().
- Mouse cursor is inside the window - checks if the mouse cursor is inside the window.

## Keyboard

GDevelop gives access to all inputs made on the keyboard. This includes conditions to check if a key was pressed or released.(no content)To test a key press using the condition, you need to enter the key name in the form of text expression. For example, if you want to check condition for left arrow key press, you need to enter "Left" in the field. Make sure that the key name is surrounded by quotes.(no content)Conditions check keys pressed on a keyboard. Note that this does not work with on-screen keyboard on touch devices: use instead mouse/touch conditions when making a game for mobile/touchscreen devices.

## Gamepad

Xbox, PlayStation and generic controllers are supported. This feature can be activated by adding the Gamepad extension to your project. You will then be able to use conditions and expressions to check if a gamepad is connected, if a button is pressed, released or if a stick is pushed.(no content)Gamepad button pressed - checks if a button is pressed on a gamepad. Buttons can be: Xbox: "A", "B", "X", "Y", "LB", "RB", "LT", "RT", "BACK", "START"; PS4: "CROSS", "SQUARE", "CIRCLE", "TRIANGLE", "L1", "L2", "R1", "R2", "SHARE", "OPTIONS", "PS_BUTTON", "CLICK_TOUCHPAD"; Other: "UP", "DOWN", "LEFT", "RIGHT", "CLICK_STICK_LEFT", "CLICK_STICK_RIGHT".

## Multitouch Joystick

Virtual joysticks are used in mobile games to give players similar controls to real gamepads. While a virtual joystick could be created manually with a mix of objects and events, it's often simpler to use a virtual joystick offered in the Asset Store. They also come with behaviors that allow developers to easily move an object with it.

Here are the search results for GameMaker Studio 2 input documentation:

## Official GameMaker Documentation

In GameMaker, you can use dedicated mouse or keyboard events on PCs or gesture events on mobile, but when you need more control, you can use game input functions to get which buttons or keys have been pressed or released, retrieve touches on a screen, or how much a gamepad joystick has been moved. There are many functions for game input split into sections related to specific input methods.

**Official Manual Links:**

- [Game Input Overview](https://manual.gamemaker.io/lts/en/GameMaker_Language/GML_Reference/Game_Input/Game_Input.htm)
- [Gamepad Input](https://manual.gamemaker.io/lts/en/GameMaker_Language/GML_Reference/Game_Input/GamePad_Input/Gamepad_Input.htm)

## Gamepad Functions

GameMaker has a number of dedicated functions that can be used to detect both analog and digital controls from multiple connected gamepads. These functions work similar to Device Inputs, allowing you to detect up to four different XInput gamepads (and up to 8 DirectInput).(no content)When a gamepad is plugged in or removed, an asynchronous System event is triggered where you can handle the situation using appropriate functions.(no content)When using DirectInput gamepads on Windows or generic gamepads on other platforms, the constants may not match expected buttons due to the fragmented API implementation by manufacturers. It is recommended to have a gamepad setup screen where players can redefine buttons, using gamepad "mapping" functions available on Windows Desktop, Ubuntu, macOS, and Android.

## Third-Party Input Libraries

### Input Library (by Juju Adams)
Input is a GameMaker Studio 2 input manager that unifies native keyboard, mouse, and gamepad support to create an easy and robust mega-library.(no content)Input is built for GameMaker 2022 LTS and later, uses strictly native GML code, and is supported on every export platform. It is free and open source forever, including for commercial use.(no content)Input allows you to detect double taps, long holds, rapidfire, combos, and chords, and includes easy-to-implement accessibility features.

Here's what I found about Phaser 3's input API documentation for keyboard, mouse, gamepad, and pointer:

## Phaser 3 Input System Overview

Internally there is a global Input Manager and every Scene has an instance of the Input Plugin. The Input Manager is responsible for listening for native DOM events, such as mouse movement, touch gestures and keyboard presses. It then passes these events on to the Input Plugins, which in turn processes them.(no content)Phaser combines mouse and touch (pointer) events into one single unified API. When you enable a Game Object for input and listen for an event, such as 'pointerdown', it doesn't matter if it was a mouse click on a desktop, or a finger pointer on a mobile that caused it. Phaser will emit the same event for your game to listen for.

### Key Documentation Resources

**Current Documentation (recommended):**

- https://docs.phaser.io/phaser/concepts/input (Input concepts)
- https://docs.phaser.io/api-documentation/class/input-inputplugin (InputPlugin API)
- https://docs.phaser.io/api-documentation/class/input-inputmanager (InputManager API)
- https://newdocs.phaser.io (Latest API reference)

**Note:** The legacy documentation at photonstorm.github.io is 4+ years out of date. Please see https://newdocs.phaser.io for current documentation.

### Input Architecture

Keyboard and Gamepad are plugins, handled directly by the InputPlugin class. It then manages the events, pointer creation and general hit test related operations.

### Key Components

**InputPlugin (Scene-level)** - Provides access to:

- An instance of the Gamepad Plugin class, if enabled via the input.gamepad Scene or Game Config property. Use this to create access Gamepads connected to the browser and respond to gamepad buttons.
- An instance of the Keyboard Plugin class, if enabled via the input.keyboard Scene or Game Config property. Use this to create Key objects and listen for keyboard specific events.

Here's what I found about Unity's Input System action API for `WasPressedThisFrame`, `WasReleasedThisFrame`, and `ReadValue`:

## ReadValue\<TValue\>()

`ReadValue<TValue>()` reads the current value of the action. This is the last value received on `started` or `performed`. If the action is in canceled or waiting phase, it returns `default(TValue)`.(no content)This method can be used as an alternative to hooking into `started`, `performed`, and/or `canceled` callbacks. Instead, this API acts more like a polling API that can be called, for example, as part of `MonoBehaviour.Update`.

Example usage:
```csharp
var moveDirection = moveAction.ReadValue<Vector2>();
```

## WasPressedThisFrame()

In the frame where the space bar is pressed, `WasPressedThisFrame()` will be true (because the button/key is now pressed) but `WasPerformedThisFrame` will still be false (because the hold has not been performed yet).(no content)This method will disregard whether the action is currently enabled or disabled. It will keep returning true for the duration of the frame even if the action was subsequently disabled in the frame. The meaning of "frame" is either the current dynamic update (`MonoBehaviour.Update`) or the current fixed update (`MonoBehaviour.FixedUpdate`) depending on the value of the `updateMode` setting.

## WasReleasedThisFrame()

Returns true if the action's value crossed the release threshold (see `buttonReleaseThreshold`) at any point in the frame after being in pressed state. This method works with any type of action, not just buttons. Also note that because this operates on the results of `EvaluateMagnitude()`, it works with many kinds of controls, not just buttons.

## Example Usage

Here's a typical polling pattern in `Update()`:
```csharp
public PlayerInput playerInput;

public void Update() {

Here are the search results for game input detection patterns related to double tap, hold duration, and long press:

## Key Findings

### Unity Input System (Official API)
A `HoldInteraction` requires the user to hold a Control for duration seconds before the Input System triggers the Action. A `TapInteraction` requires the user to press and release a Control within duration seconds to trigger the Action.(no content)A `SlowTapInteraction` requires the user to press and hold a Control for a minimum duration of duration seconds, and then release it, to trigger the Action. A `MultiTapInteraction` requires the user to press and release a Control within tapTime seconds tapCount times, with no more than tapDelay seconds passing between taps. You can use this to detect double-click or multi-click gestures.(no content)While Performed is typically the phase that triggers the actual response to an Interaction, Started and Canceled can be useful for providing UI feedback while the Interaction is in progress. For example, when a hold is Started, the app can display a progress bar that fills up until the hold time has been reached. If, however, the hold is Canceled before it completes, the app can reset the progress bar to the beginning.

### libGDX GestureDetector
A gesture could be a pinch with two fingers to indicate the desire to zoom, a tap or double tap, a long press and so on. libGDX provides a GestureDetector that lets you detect gestures including tap (user touches and lifts finger). The finger must not move outside a specified square area around the initial touch position for a tap to be registered. Multiple consecutive taps will be detected if the user performs taps within a specified time interval.

### Arduino Capacitive Touch Library
The `detect_touchFromNoise()` function returns 1-4 based on the input detected: 1 = singletap, 2 = doubletap, 3 = shortpress, 4 = longpress.(no content)The library allows setting thresholds with `set_inputTypeThresholds(20, 40, 70, 150)` for the four input types (singletap, shortpress, longpress, doubletapspeed).

### Android GestureDetector
In mobile development, gesture detection is key for your app to understand how users interact, such as single tap, double tap, long press, and scrolling actions. The Android GestureDetector provides an easy way to handle various gestures. With three interfaces — OnGestureListener, OnDoubleTapListener and OnContextClickListener — you can use SimpleOnGestureListener which implements all these interfaces.(no content)For long press: callback on user pressing and holding after a certain amount of time. For single tap: notified after a single tap, with a slight delay to ensure no other gesture on the next touch (such as a double tap).

### SwiftUI Pattern
Order the gestures by their complexity, starting with the most intricate and progressing to simpler ones. For example, if you need a LongPressGesture and a TapGesture, put the former before the latter. If adding a double tap, place it before the single TapGesture and after the LongPressGesture. The reason is that basic gestures like single tap, when placed before complex ones, cause the system to ignore the latter.

Here are the search results for game input consumed/consume input propagation patterns:

## Key Findings

### General Pattern
In order to allow one system to "consume" an event, thereby preventing other systems from also handling it, a callback system can be added for each event type.(no content)When an event is generated, the event caller can iterate over the listeners until one listener consumes it, at which point the propagation stops.

A common implementation uses an `EventReply` enum:
The callback returns `EventReply::CONSUMED` to indicate it handled the event, or `EventReply::UNCONSUMED` to let it propagate further.

### Godot Engine
There are four stages of Event Handling where a node may override the Event Handler Function to consume the Event and possibly set it as being handled to stop it propagating further.(no content)In the handler code you can set the event as handled so that the following `_unhandled_input(event)` method does not respond to it, effectively disabling game-playing control while a popup GUI is being used.(no content)The `_unhandled_input(event)` method is useful for handling game player inputs whose events have not already been set as handled.

### Unity
"Stopping an event's propagation and giving an element focus are distinct actions."(no content)When you click a button, it stops the propagation and allows only the button to react to being pressed, but it doesn't prevent the other default actions for the click.(no content)Other input modules change what input is consumed, but all events still go through the Event System to execute.

### Unreal Engine
In UE5's Enhanced Input configuration, there's a "Consume Input" flag that can be checked on Input Actions, though there are reports of issues where input still propagates despite this setting.

### Phaser
Higher-up event handlers can stop the propagation of this event. Events flow in a specific order with options to halt propagation.

# Input API Analysis

Based on the provided web page content, I cannot extract specific information about verbs, chords, combos, long holds, double taps, or the API structure you're asking about.

**What the content actually contains:**

The page code is a Docsify documentation configuration file. It includes:

- Documentation setup scripts (title, meta descriptions, sidebar loading)
- Theme customization using CSS variables and hex-to-HSL color conversion
- Version selector functionality for multiple documentation versions
- Navigation and anchor link handling
- Code syntax highlighting and formatting rules

**Why the requested information isn't present:**

The excerpt you provided appears to be from a documentation *framework* rather than the actual API documentation itself. The code handles how documentation is *displayed*, not what it documents. The actual information about input handling (verbs, chords, combos, etc.) would be in separate markdown files loaded by this framework.

To extract the API structure details you need, you would need to provide the actual documentation content files rather than the configuration script.

Here are the search results for game input rebinding/remapping UI implementation:

## Unity Input System

Unity provides an optional UI that is activated when an interactive rebind is started and deactivated when the rebind is finished. This is normally used to display an overlay over the current UI while the system is waiting for a control to be actuated.(no content)If neither rebindPrompt nor rebindOverlay is set, the component will temporarily replace the bindingText with "Waiting...".(no content)Once the UI elements are set up, you can implement the logic to start the rebinding process. When the user clicks the button, you want to hide the button UI and show a waiting message. You also need to switch the player's input to a different action map, which effectively pauses the gameplay.(no content)You can use the Input System's RebindingOperation API to perform the rebinding and configure it with the necessary settings. You should also create a method to handle the completion of the rebinding operation and dispose of the operation to prevent memory leaks.

## Unreal Engine

There's a CustomBindings project demonstrating the use of the KeyBindingUtil library for remapping game input keys. It has a very basic UI menu, made with UMG and Blueprints.(no content)KeyBindingUtil is a C++ library, also exposed to Blueprints, that allows you to create the key rebinding/remapping system for your game, useful for creating traditional Settings/Controls menus.(no content)The Victory BP Library provides nodes for rebinding keys at runtime in a packaged game for use with a UMG Key Rebinding menu. The core C++ code modifies ActionMappings, saves key mappings to disk, and rebuilds input.(no content)There's also an Unreal Engine 5.6 tutorial about rebinding Input Actions to new keys using Enhanced Input User Settings.

## InControl (Third-Party Library)

InControl provides BindingListenOptions with settings like IncludeControllers, IncludeMouseButtons, and IncludeKeys to control what input sources are listened for when rebinding.(no content)You can use OnBindingFound callbacks to handle special cases like canceling with Escape: when a binding is found matching Escape, you can call action.StopListeningForBinding() and return false.

Based on the search results, here's the documentation for p5play's input API:

## p5play Input API

### Input Devices
p5play provides these input devices: `kb` / `keyboard` for the keyboard, `mouse` for the mouse, `contros` / `controllers` for game controllers, and `touches` for touch screen inputs. These input devices all use the same simple functions for getting the state of an input: `presses`, `pressing`, and `released`.

### Input State Values
The input state values work as follows:
- -3 means input was pressed and released on the same frame
- -2 means input was released after being held
- -1 means input was released
- 0 means input is not pressed
- 1 means input was pressed
- >1 means input is still being pressed

### Keyboard (`kb`)
Input devices store the state of all their inputs as properties. For example, `kb.space` stores how many frames the user has been pressing the space key. It gets reset when the user releases the input.(no content)`kb` tracks nearly every key on the keyboard, including 'enter', 'backspace', and 'control'. Note that letter input is not case sensitive.(no content)To check if a user is pressing shift use: `kb.pressing('shift')`.(no content)Since the WASD keys are commonly used to control the player character's movement, you can use the direction names 'up', 'down', 'left', and 'right' to detect WASD and arrow key presses. Arrow keys can also be detected separately using 'arrowUp', 'arrowDown', 'arrowLeft', and 'arrowRight'.(no content)In local two player games it's common for the second player to use the IJKL keys for movement. These keys can be referenced using 'up2', 'down2', 'left2', and 'right2'.

### Mouse
The default mouse input is the 'left' button, a one finger click on trackpads. You can also use 'right' (two finger click) and 'center'.(no content)mouse.x and mouse.y store the position of the mouse in the world, based on the camera's position.(no content)Note that `mouse.x` is the x position of the mouse on the canvas and `sprite.mouse.x` is the x position of the mouse relative to the sprite.

### Controllers (`contros`)
The `contros` array (aka controllers) contains an object for each game controller detected by your web browser.(no content)Each controller object stores the input states of these buttons: a, b, x, y, l (left bumper), r (right bumper), lt (left trigger), rt (right trigger), up, down, left, right (D-pad), lsb (left stick button), rsb (right stick button), start, and select. `leftStick` and `rightStick` represent the positions of the analog sticks as objects with x and y properties. These values range from -1 to 1, with 0 indicating the center position.(no content)Some controllers have analog triggers, and their positions are stored as numbers ranging from 0 to 1 in `leftTrigger` and `rightTrigger`.

501:**Step 3: Basic action binding**
502-- [ ] Action struct: name, array of controls, pressed/down/released state
503-- [ ] Control struct: type (KEY, MOUSE, BUTTON, AXIS), code, sign (for axes)
504-- [ ] `input_bind(action, controls)` — parse control strings, add to action
505-- [ ] `is_pressed(action)` — true if any bound control just pressed
506-- [ ] `is_down(action)` — true if any bound control held (returns axis value if analog)
507-- [ ] `is_released(action)` — true if any bound control just released
508-- [ ] Per-frame action state computation from raw input states
509-- [ ] Track last input type per action query (for Step 10)
510-
511-**Step 4: Unbinding and bind_all**
512-- [ ] `input_unbind(action, control)` — remove specific control from action
513-- [ ] `input_unbind_all(action)` — remove all controls from action
514-- [ ] `input_bind_all()` — bind every key/button to action with same name
515-  - All keyboard keys → `'a'`, `'space'`, `'left'`, etc.
516-  - Mouse buttons → `'mouse_1'`, `'mouse_2'`, `'wheel_up'`, `'wheel_down'`
517-
518-**Step 5: Axis helpers**
519-- [ ] `input_get_axis(negative, positive)` — returns -1 to 1
520-  - Digital: `is_down(positive) - is_down(negative)`
521-  - Analog: uses actual axis values if bound to gamepad axis
522-- [ ] `input_get_vector(left, right, up, down)` — returns x, y
523-  - Normalized to prevent faster diagonal movement
524-  - `len = sqrt(x*x + y*y); if len > 1 then x, y = x/len, y/len`
525-
526-**Step 6: Gamepad support**
527-- [ ] SDL gamepad initialization and hotplug handling
528-- [ ] `gamepad_is_connected()` — true if at least one gamepad connected
529-- [ ] `gamepad_get_axis(axis)` — raw axis value (-1 to 1)
530-  - Axes: `'leftx'`, `'lefty'`, `'rightx'`, `'righty'`, `'triggerleft'`, `'triggerright'`

533-- [ ] Control string parsing: `'button:a'`, `'button:start'`, `'axis:leftx+'`, `'axis:lefty-'`
534-
535-**Step 7: Chords**
536-- [ ] Chord struct: name, array of action names, pressed/down/released state
537-- [ ] `input_bind_chord(name, actions)` — e.g., `('sprint_jump', {'shift', 'space'})`
538-- [ ] Chord is down when ALL actions are down
539-- [ ] Chord pressed when it becomes down (wasn't down last frame)
540-- [ ] Chord released when it stops being down
541-- [ ] Chords queryable via `is_pressed`/`is_down`/`is_released` (same namespace as actions)
542-
543:**Step 8: Sequences**
544-- [ ] Sequence struct: name, array of {action, delay} pairs, state machine
545-- [ ] `input_bind_sequence(name, sequence)` — e.g., `('dash', {'right', 0.2, 'right'})`
546-- [ ] State machine tracks: current step, last press time
547-- [ ] Advances when next action pressed within time window
548-- [ ] Resets if timeout or wrong action pressed
549-- [ ] Sequence fires (is_pressed returns true) when final action completes in time
550:- [ ] Sequences queryable via `is_pressed`/`is_down`/`is_released`

552-**Step 9: Holds**
553-- [ ] Hold struct: name, source action, duration, state (waiting/triggered)
554-- [ ] `input_bind_hold(name, duration, action)` — e.g., `('charge', 1.0, 'attack')`
555-- [ ] Tracks how long source action has been held
556-- [ ] `is_pressed` fires on the frame hold duration is reached
557-- [ ] `is_down` true while held after duration reached
558-- [ ] `is_released` fires when released after duration was reached
559-- [ ] Resets when source action released before duration
560-- [ ] Holds queryable via `is_pressed`/`is_down`/`is_released`

563-- [ ] Track last input type: `'keyboard'`, `'mouse'`, or `'gamepad'`
564-- [ ] Updated whenever any input is received
565-- [ ] `input_get_last_type()` — returns current type string

568:**Step 11: Rebinding capture**
569-- [ ] Capture mode flag
570:- [ ] `input_start_capture()` — enter capture mode, suppress normal input processing
571-- [ ] While in capture mode: wait for any key/button/axis press
572-- [ ] Store captured control as string (e.g., `'key:w'`, `'button:a'`)
573:- [ ] `input_get_captured()` — returns control string if captured, nil otherwise
574-- [ ] `input_stop_capture()` — exit capture mode, clear captured value

     8→
     9→| Area | Decision | Rationale |
    10→|------|----------|-----------|
    11→| Renderer | OpenGL | Smooth rotation, additive blending, performance headroom, console-portable |
    12→| Audio | TBD (miniaudio or SoLoud) | Need pitch shifting; SDL_mixer insufficient |
    13→| Physics | Box2D 3.1 | Already used, true ball-to-ball collisions needed |
    14→| Scripting | Lua 5.4 + YueScript | Build-time compilation with `-r` flag for line numbers |
    15→| Timestep | Fixed 120Hz physics, 60Hz render | Decoupled for pixel-perfect visuals with responsive input |
    16→| Resolution | Per-game configurable | 480×270, 640×360, or custom; aspect-ratio scaling with letterboxing |
    17→| C Structure | Single anchor.c | Monolithic file, easier navigation |
    18→| Resources | Live forever | Games are small enough; no unloading needed |
    19→| Linking | Static | No DLLs; SDL2, Lua, audio all compiled in |
    20→| Distribution | Single executable | Zip-append for game content, extractable by modders |

60:Everything about this player — its initial state, its movement logic, its rendering — is visible in one place. Compare to architectures where you'd define a Player class in one file, register it with an entity manager, subscribe to input events through an event bus, and render it through a render system that queries for Renderable components. The expressiveness is similar, but the *understanding* is scattered across four or five locations.

  1256→- **Language:** C99 with Lua 5.4 scripting (YueScript compiled to Lua)
  1257→- **Window/Input:** SDL2
  1258→- **Audio:** TBD (miniaudio or SoLoud — needs pitch shifting support)
  1259→- **Graphics:** OpenGL 3.3 Core Profile (WebGL 2.0 compatible)

  1265→## Engine State
  1266→
  1267→The engine exposes timing and frame information to Lua:
  1268→
  1269→```lua
  1270→an.frame      -- Render frame count (increments each rendered frame at 60Hz)
  1271→an.step       -- Physics step count (increments each physics tick at 120Hz)
  1272→an.game_time  -- Accumulated game time in seconds
  1273→```
  1274→
  1275→Useful for:
  1276→- Deterministic effects (use `an.step` instead of random for consistent patterns)
  1277→- Debugging and profiling
  1278→- Replay systems (verify sync with step count)
