# Yugine Input Guide
Any Javascript object can be controlled by a Player, becoming a pawn. Each Player has their input sent to all of their pawns. To receive input, pawns must have a specifically named object. There are multiple possible input systems to receive input on.
## inputs
The 'inputs' object receives emacs-like keyboard controls, like C-K (ctrl-K), M-k (alt-k), k (just k).
inputs['C-k'] | function to call when C-k is pressed
inputs['C-k'].up | function to call when C-k is released
inputs['C-k'].rep | True if this down action is repeatable
These inputs are ideal for editor controls.
For these controls, pawn control order can matter. Pawns that are controlled later consume input commands, making it easy to control a specific editor component to alter the functionality of a portion of the editor.
## actions & input maps
Actions are a named input, ideal for game controls. Rather than say that "x" jumps, it might be better to name a "jump" action.

/// how layouting works. From now there will be an internal minimum
/// row height derived from font height. If you need a row smaller than
/// that you can directly set it by `nk_layout_set_min_row_height` and
/// reset the value back by calling `nk_layout_reset_min_row_height.

/// - 2016/12/03 (1.29.0) - Changed text wrapping to process words not characters.
/// - 2016/11/22 (1.28.6) - Fixed window minimized closing bug.
/// - 2016/11/19 (1.28.5) - Fixed abstract combo box closing behavior.
/// - 2016/11/19 (1.28.4) - Fixed tooltip flickering.
/// - 2016/11/19 (1.28.3) - Fixed memory leak caused by popup repeated closing.
/// - 2016/11/18 (1.28.2) - Fixed memory leak caused by popup panel allocation.
/// - 2016/11/10 (1.28.1) - Fixed some warnings and C++ error.
/// - 2016/11/10 (1.28.0) - Added additional `nk_button` versions which allows to directly
/// pass in a style struct to change buttons visual.
/// - 2016/11/10 (1.27.0) - Added additional `nk_tree` versions to support external state
/// storage. Just like last the `nk_group` commit the main
/// advantage is that you optionally can minimize nuklears runtime
/// memory consumption or handle hash collisions.
/// - 2016/11/09 (1.26.0) - Added additional `nk_group` version to support external scrollbar
/// offset storage. Main advantage is that you can externalize
/// the memory management for the offset. It could also be helpful
/// if you have a hash collision in `nk_group_begin` but really
/// want the name. In addition I added `nk_list_view` which allows
/// to draw big lists inside a group without actually having to
/// commit the whole list to nuklear (issue #269).
/// - 2016/10/30 (1.25.1) - Fixed clipping rectangle bug inside `nk_draw_list`.
/// - 2016/10/29 (1.25.0) - Pulled `nk_panel` memory management into nuklear and out of
/// the hands of the user. From now on users don't have to care
/// about panels unless they care about some information. If you
/// still need the panel just call `nk_window_get_panel`.
/// - 2016/10/21 (1.24.0) - Changed widget border drawing to stroked rectangle from filled
/// rectangle for less overdraw and widget background transparency.
/// - 2016/10/18 (1.23.0) - Added `nk_edit_focus` for manually edit widget focus control.
/// - 2016/09/29 (1.22.7) - Fixed deduction of basic type in non `<stdint.h>` compilation.
/// - 2016/09/29 (1.22.6) - Fixed edit widget UTF-8 text cursor drawing bug.
/// - 2016/09/28 (1.22.5) - Fixed edit widget UTF-8 text appending/inserting/removing.
/// - 2016/09/28 (1.22.4) - Fixed drawing bug inside edit widgets which offset all text
/// text in every edit widget if one of them is scrolled.
/// - 2016/09/28 (1.22.3) - Fixed small bug in edit widgets if not active. The wrong
/// text length is passed. It should have been in bytes but
/// was passed as glyphs.
/// - 2016/09/20 (1.22.2) - Fixed color button size calculation.
/// - 2016/09/20 (1.22.1) - Fixed some `nk_vsnprintf` behavior bugs and removed `<stdio.h>`
/// again from `NK_INCLUDE_STANDARD_VARARGS`.
/// - 2016/09/18 (1.22.0) - C89 does not support vsnprintf only C99 and newer as well
/// as C++11 and newer. In addition to use vsnprintf you have
/// to include <stdio.h>. So just defining `NK_INCLUDE_STD_VAR_ARGS`
/// is not enough. That behavior is now fixed. By default if
/// both varargs as well as stdio is selected I try to use
/// vsnprintf if not possible I will revert to vsprintf. If
/// varargs but not stdio was defined I will use my own function.
/// - 2016/09/15 (1.21.2) - Fixed panel `close` behavior for deeper panel levels.
/// - 2016/09/15 (1.21.1) - Fixed C++ errors and wrong argument to `nk_panel_get_xxxx`.
/// - 2016/09/13 (1.21.0) - !BREAKING! Fixed nonblocking popup behavior in menu, combo,
/// and contextual which prevented closing in y-direction if
/// popup did not reach max height.
/// In addition the height parameter was changed into vec2
/// for width and height to have more control over the popup size.
/// - 2016/09/13 (1.20.3) - Cleaned up and extended type selection.
/// - 2016/09/13 (1.20.2) - Fixed slider behavior hopefully for the last time. This time
/// all calculation are correct so no more hackery.
/// - 2016/09/13 (1.20.1) - Internal change to divide window/panel flags into panel flags and types.
/// Suprisinly spend years in C and still happened to confuse types
/// with flags. Probably something to take note.
/// - 2016/09/08 (1.20.0) - Added additional helper function to make it easier to just
/// take the produced buffers from `nk_convert` and unplug the
/// iteration process from `nk_context`. So now you can
/// just use the vertex,element and command buffer + two pointer
/// inside the command buffer retrieved by calls `nk__draw_begin`
/// and `nk__draw_end` and macro `nk_draw_foreach_bounded`.
/// - 2016/09/08 (1.19.0) - Added additional asserts to make sure every `nk_xxx_begin` call
/// for windows, popups, combobox, menu and contextual is guarded by
/// `if` condition and does not produce false drawing output.
/// - 2016/09/08 (1.18.0) - Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT`
/// to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and
/// `NK_SYMBOL_RECT_OUTLINE`.
/// - 2016/09/08 (1.17.0) - Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE`
/// to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and
/// `NK_SYMBOL_CIRCLE_OUTLINE`.
/// - 2016/09/08 (1.16.0) - Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES`
/// is not defined by supporting the biggest compiler GCC, clang and MSVC.
/// - 2016/09/07 (1.15.3) - Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error.
/// - 2016/09/04 (1.15.2) - Fixed wrong combobox height calculation.
/// - 2016/09/03 (1.15.1) - Fixed gaps inside combo boxes in OpenGL.
/// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and
/// instead made it user provided. The range of types to convert
/// to is quite limited at the moment, but I would be more than
/// happy to accept PRs to add additional.
/// - 2016/08/30 (1.14.2) - Removed unused variables.
/// - 2016/08/30 (1.14.1) - Fixed C++ build errors.
/// - 2016/08/30 (1.14.0) - Removed mouse dragging from SDL demo since it does not work correctly.
/// - 2016/08/30 (1.13.4) - Tweaked some default styling variables.
/// - 2016/08/30 (1.13.3) - Hopefully fixed drawing bug in slider, in general I would
/// refrain from using slider with a big number of steps.
/// - 2016/08/30 (1.13.2) - Fixed close and minimize button which would fire even if the
/// window was in Read Only Mode.
/// - 2016/08/30 (1.13.1) - Fixed popup panel padding handling which was previously just
/// a hack for combo box and menu.
/// - 2016/08/30 (1.13.0) - Removed `NK_WINDOW_DYNAMIC` flag from public API since
/// it is bugged and causes issues in window selection.
/// - 2016/08/30 (1.12.0) - Removed scaler size. The size of the scaler is now
/// determined by the scrollbar size.
/// - 2016/08/30 (1.11.2) - Fixed some drawing bugs caused by changes from 1.11.0.
/// - 2016/08/30 (1.11.1) - Fixed overlapping minimized window selection.
/// - 2016/08/30 (1.11.0) - Removed some internal complexity and overly complex code
/// handling panel padding and panel border.
/// - 2016/08/29 (1.10.0) - Added additional height parameter to `nk_combobox_xxx`.
/// - 2016/08/29 (1.10.0) - Fixed drawing bug in dynamic popups.
/// - 2016/08/29 (1.10.0) - Added experimental mouse scrolling to popups, menus and comboboxes.
/// - 2016/08/26 (1.10.0) - Added window name string prepresentation to account for
/// hash collisions. Currently limited to `NK_WINDOW_MAX_NAME`
/// which in term can be redefined if not big enough.
/// - 2016/08/26 (1.10.0) - Added stacks for temporary style/UI changes in code.
/// - 2016/08/25 (1.10.0) - Changed `nk_input_is_key_pressed` and 'nk_input_is_key_released'
/// to account for key press and release happening in one frame.
/// - 2016/08/25 (1.10.0) - Added additional nk_edit flag to directly jump to the end on activate.
/// - 2016/08/17 (1.09.6) - Removed invalid check for value zero in `nk_propertyx`.
/// - 2016/08/16 (1.09.5) - Fixed ROM mode for deeper levels of popup windows parents.
/// - 2016/08/15 (1.09.4) - Editbox are now still active if enter was pressed with flag
/// `NK_EDIT_SIG_ENTER`. Main reasoning is to be able to keep
/// typing after committing.
/// - 2016/08/15 (1.09.4) - Removed redundant code.
/// - 2016/08/15 (1.09.4) - Fixed negative numbers in `nk_strtoi` and remove unused variable.
/// - 2016/08/15 (1.09.3) - Fixed `NK_WINDOW_BACKGROUND` flag behavior to select a background
/// window only as selected by hovering and not by clicking.
/// - 2016/08/14 (1.09.2) - Fixed a bug in font atlas which caused wrong loading
/// of glyphs for font with multiple ranges.
/// - 2016/08/12 (1.09.1) - Added additional function to check if window is currently
/// hidden and therefore not visible.
/// - 2016/08/12 (1.09.1) - nk_window_is_closed now queries the correct flag `NK_WINDOW_CLOSED`
/// instead of the old flag `NK_WINDOW_HIDDEN`.
/// - 2016/08/09 (1.09.0) - Added additional double version to nk_property and changed
/// the underlying implementation to not cast to float and instead
/// work directly on the given values.
/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
/// floating pointer number to string conversion for additional
/// precision.
/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
/// string to floating point number conversion for additional
/// precision.
/// - 2016/08/08 (1.07.2) - Fixed compiling error without define `NK_INCLUDE_FIXED_TYPE`.
/// - 2016/08/08 (1.07.1) - Fixed possible floating point error inside `nk_widget` leading
/// to wrong wiget width calculation which results in widgets falsely
/// becoming tagged as not inside window and cannot be accessed.
/// - 2016/08/08 (1.07.0) - Nuklear now differentiates between hiding a window (NK_WINDOW_HIDDEN) and
/// closing a window (NK_WINDOW_CLOSED). A window can be hidden/shown
/// by using `nk_window_show` and closed by either clicking the close
/// icon in a window or by calling `nk_window_close`. Only closed
/// windows get removed at the end of the frame while hidden windows
/// remain.
/// - 2016/08/08 (1.06.0) - Added `nk_edit_string_zero_terminated` as a second option to

/// define `NK_INCLUDE_STANDARD_VARARGS` to allow more fine
/// grained controlled over library includes.
/// - 2016/08/06 (1.04.5) - Changed memset calls to `NK_MEMSET`.
/// - 2016/08/04 (1.04.4) - Fixed fast window scaling behavior.
/// - 2016/08/04 (1.04.3) - Fixed window scaling, movement bug which appears if you
/// move/scale a window and another window is behind it.
/// If you are fast enough then the window behind gets activated
/// and the operation is blocked. I now require activating
/// by hovering only if mouse is not pressed.
/// - 2016/08/04 (1.04.2) - Fixed changing fonts.
/// - 2016/08/03 (1.04.1) - Fixed `NK_WINDOW_BACKGROUND` behavior.

/// simplify memory management by removing the need to
/// allocate the pool.
/// - 2016/07/29 (1.02.0) - Added auto scrollbar hiding window flag which if enabled
/// will hide the window scrollbar after NK_SCROLLBAR_HIDING_TIMEOUT
/// seconds without window interaction. To make it work
/// you have to also set a delta time inside the `nk_context`.
/// - 2016/07/25 (1.01.1) - Fixed small panel and panel border drawing bugs.
/// - 2016/07/15 (1.01.0) - Added software cursor to `nk_style` and `nk_context`.

/// ## About
/// This is a minimal state immediate mode graphical user interface toolkit
/// written in ANSI C and licensed under public domain. It was designed as a simple
/// embeddable user interface for application and does not have any dependencies,
/// a default renderbackend or OS window and input handling but instead provides a very modular
/// library approach by using simple input state for input and draw
/// commands describing primitive shapes as output. So instead of providing a
/// layered library that tries to abstract over a number of platform and
/// render backends it only focuses on the actual UI.
///
/// ## Highlights
/// - Graphical user interface toolkit
/// - Single header library
/// - Written in C89 (a.k.a. ANSI C or ISO C90)
/// - Small codebase (~18kLOC)
/// - Focus on portability, efficiency and simplicity
/// - No dependencies (not even the standard library if not wanted)
/// - Fully skinnable and customizable
/// - Low memory footprint with total memory control if needed or wanted
/// - UTF-8 support
/// - No global or hidden state
/// - Customizable library modules (you can compile and use only what you need)
/// - Optional font baker and vertex buffer output
///
/// ## Features
/// - Absolutely no platform dependent code
/// - Memory management control ranging from/to
/// - Ease of use by allocating everything from standard library
/// - Control every byte of memory inside the library
/// - Font handling control ranging from/to
/// - Use your own font implementation for everything
/// - Use this libraries internal font baking and handling API
/// - Drawing output control ranging from/to
/// - Simple shapes for more high level APIs which already have drawing capabilities
/// - Hardware accessible anti-aliased vertex buffer output
/// - Customizable colors and properties ranging from/to
/// - Simple changes to color by filling a simple color table
/// - Complete control with ability to use skinning to decorate widgets
/// - Bendable UI library with widget ranging from/to
/// - Basic widgets like buttons, checkboxes, slider, ...
/// - Advanced widget like abstract comboboxes, contextual menus,...
/// - Compile time configuration to only compile what you need
/// - Subset which can be used if you do not want to link or use the standard library
/// - Can be easily modified to only update on user input instead of frame updates
///
/// ## Usage
/// This library is self contained in one single header file and can be used either
/// in header only mode or in implementation mode. The header only mode is used
/// by default when included and allows including this header in other headers
/// and does not contain the actual implementation. <br /><br />
///
/// The implementation mode requires to define the preprocessor macro
/// NK_IMPLEMENTATION in *one* .c/.cpp file before #including this file, e.g.:
///
/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~C
/// #define NK_IMPLEMENTATION
/// #include "nuklear.h"
/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
///
/// Also optionally define the symbols listed in the section "OPTIONAL DEFINES"
/// below in header and implementation mode if you want to use additional functionality
/// or need more control over the library.
///
/// !!! WARNING
/// Every time nuklear is included define the same compiler flags. This very important not doing so could lead to compiler errors or even worse stack corruptions.
///
/// ### Flags
/// Flag | Description
/// --------------------------------|------------------------------------------
/// NK_PRIVATE | If defined declares all functions as static, so they can only be accessed inside the file that contains the implementation
/// NK_INCLUDE_FIXED_TYPES | If defined it will include header `<stdint.h>` for fixed sized types otherwise nuklear tries to select the correct type. If that fails it will throw a compiler error and you have to select the correct types yourself.
/// NK_INCLUDE_DEFAULT_ALLOCATOR | If defined it will include header `<stdlib.h>` and provide additional functions to use this library without caring for memory allocation control and therefore ease memory management.
/// NK_INCLUDE_STANDARD_IO | If defined it will include header `<stdio.h>` and provide additional functions depending on file loading.
/// NK_INCLUDE_STANDARD_VARARGS | If defined it will include header <stdarg.h> and provide additional functions depending on file loading.
/// NK_INCLUDE_STANDARD_BOOL | If defined it will include header `<stdbool.h>` for nk_bool otherwise nuklear defines nk_bool as int.
/// NK_INCLUDE_VERTEX_BUFFER_OUTPUT | Defining this adds a vertex draw command list backend to this library, which allows you to convert queue commands into vertex draw commands. This is mainly if you need a hardware accessible format for OpenGL, DirectX, Vulkan, Metal,...
/// NK_INCLUDE_FONT_BAKING | Defining this adds `stb_truetype` and `stb_rect_pack` implementation to this library and provides font baking and rendering. If you already have font handling or do not want to use this font handler you don't have to define it.
/// NK_INCLUDE_DEFAULT_FONT | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font
/// NK_INCLUDE_COMMAND_USERDATA | Defining this adds a userdata pointer into each command. Can be useful for example if you want to provide custom shaders depending on the used widget. Can be combined with the style structures.
/// NK_BUTTON_TRIGGER_ON_RELEASE | Different platforms require button clicks occurring either on buttons being pressed (up to down) or released (down to up). By default this library will react on buttons being pressed, but if you define this it will only trigger if a button is released.
/// NK_ZERO_COMMAND_MEMORY | Defining this will zero out memory for each drawing command added to a drawing queue (inside nk_command_buffer_push). Zeroing command memory is very useful for fast checking (using memcmp) if command buffers are equal and avoid drawing frames when nothing on screen has changed since previous frame.
/// NK_UINT_DRAW_INDEX | Defining this will set the size of vertex index elements when using NK_VERTEX_BUFFER_OUTPUT to 32bit instead of the default of 16bit
/// NK_KEYSTATE_BASED_INPUT | Define this if your backend uses key state for each frame rather than key press/release events
///
/// !!! WARNING
/// The following flags will pull in the standard C library:
/// - NK_INCLUDE_DEFAULT_ALLOCATOR
/// - NK_INCLUDE_STANDARD_IO
/// - NK_INCLUDE_STANDARD_VARARGS
///
/// !!! WARNING
/// The following flags if defined need to be defined for both header and implementation:
/// - NK_INCLUDE_FIXED_TYPES
/// - NK_INCLUDE_DEFAULT_ALLOCATOR
/// - NK_INCLUDE_STANDARD_VARARGS
/// - NK_INCLUDE_STANDARD_BOOL
/// - NK_INCLUDE_VERTEX_BUFFER_OUTPUT
/// - NK_INCLUDE_FONT_BAKING
/// - NK_INCLUDE_DEFAULT_FONT
/// - NK_INCLUDE_STANDARD_VARARGS
/// - NK_INCLUDE_COMMAND_USERDATA
/// - NK_UINT_DRAW_INDEX
///
/// ### Constants
/// Define | Description
/// --------------------------------|---------------------------------------
/// NK_BUFFER_DEFAULT_INITIAL_SIZE | Initial buffer size allocated by all buffers while using the default allocator functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't want to allocate the default 4k memory then redefine it.
/// NK_MAX_NUMBER_BUFFER | Maximum buffer size for the conversion buffer between float and string Under normal circumstances this should be more than sufficient.
/// NK_INPUT_MAX | Defines the max number of bytes which can be added as text input in one frame. Under normal circumstances this should be more than sufficient.
///
/// !!! WARNING
/// The following constants if defined need to be defined for both header and implementation:
/// - NK_MAX_NUMBER_BUFFER
/// - NK_BUFFER_DEFAULT_INITIAL_SIZE
/// - NK_INPUT_MAX
///
/// ### Dependencies
/// Function | Description
/// ------------|---------------------------------------------------------------
/// NK_ASSERT | If you don't define this, nuklear will use <assert.h> with assert().
/// NK_MEMSET | You can define this to 'memset' or your own memset implementation replacement. If not nuklear will use its own version.
/// NK_MEMCPY | You can define this to 'memcpy' or your own memcpy implementation replacement. If not nuklear will use its own version.
/// NK_INV_SQRT | You can define this to your own inverse sqrt implementation replacement. If not nuklear will use its own slow and not highly accurate version.
/// NK_SIN | You can define this to 'sinf' or your own sine implementation replacement. If not nuklear will use its own approximation implementation.
/// NK_COS | You can define this to 'cosf' or your own cosine implementation replacement. If not nuklear will use its own approximation implementation.
/// NK_STRTOD | You can define this to `strtod` or your own string to double conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
/// NK_DTOA | You can define this to `dtoa` or your own double to string conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
/// NK_VSNPRINTF| If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` and want to be safe define this to `vsnprintf` on compilers supporting later versions of C or C++. By default nuklear will check for your stdlib version in C as well as compiler version in C++. if `vsnprintf` is available it will define it to `vsnprintf` directly. If not defined and if you have older versions of C or C++ it will be defined to `vsprintf` which is unsafe.

/* Since nuklear is supposed to work on all systems providing floating point
math without any dependencies I also had to implement my own math functions
for sqrt, sin and cos. Since the actual highly accurate implementations for
the standard library functions are quite complex and I do not need high
precision for my use cases I use approximations.
Sqrt
----
For square root nuklear uses the famous fast inverse square root:
https://en.wikipedia.org/wiki/Fast_inverse_square_root with
slightly tweaked magic constant. While on today's hardware it is
probably not faster it is still fast and accurate enough for
nuklear's use cases. IMPORTANT: this requires float format IEEE 754
Sine/Cosine
-----------
All constants inside both function are generated Remez's minimax
approximations for value range 0...2*PI. The reason why I decided to
approximate exactly that range is that nuklear only needs sine and
cosine to generate circles which only requires that exact range.
In addition I used Remez instead of Taylor for additional precision:
www.lolengine.net/blog/2011/12/21/better-function-approximations.
The tool I used to generate constants for both sine and cosine
(it can actually approximate a lot more functions) can be
found here: www.lolengine.net/wiki/oss/lolremez

// stb_rect_pack.h - v1.01 - public domain - rectangle packing
// Sean Barrett 2014
//
// Useful for e.g. packing rectangular textures into an atlas.
// Does not do rotation.
//
// Before #including,
//
// #define STB_RECT_PACK_IMPLEMENTATION
//
// in the file that you want to have the implementation.
//
// Not necessarily the awesomest packing method, but better than
// the totally naive one in stb_truetype (which is primarily what
// this is meant to replace).
//
// Has only had a few tests run, may have issues.
//
// More docs to come.
//
// No memory allocations; uses qsort() and assert() from stdlib.
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
//
// This library currently uses the Skyline Bottom-Left algorithm.
//
// Please note: better rectangle packers are welcome! Please
// implement them to the same API, but with a different init
// function.
