### How Prosperon games are structured

Prosperon schews the CommonJS and ES module systems for a custom one suitable for a computer game actor model. It is more restricted than either system, while retaining their full power.

*** Script entry points
The first way you can customize Prosperon is by adding scripts to the folder you're running it from. Any file ending with *.js* is a *script* which can be ran by Prosperon.

## Actors
** Actors
The fundamental tool for building in Prosperon is the actor system. Actors run independently from each other. Actors are defined by a combination of code and data. All actors have a *master* which controls certain properties of the actor.
The most masterful actor is the *Empyrean*. The first actor you create will have the Empyrean as its master. Subsequent actors can use any other actor as its master.
| fn | description |
|---------------------|----------------------------------------------------------|
|---------------------+----------------------------------------------------------|
| spawn(text, config) | Creates an actor as the padawan of this one, using text |
| kill() | Kills an actor |
| delay(fn, seconds) | Calls 'fn' after 'seconds' with the context of the actor |
### Actor Lifetime
*** Actor Lifetime
When an actor dies, all of the actors that have it as their master will die as well.
### Turns
*** Turns
Actors get fragments of time called a *turn*. Actors which belong to different systems can have different lengths of turns.
### Actor files
*** Actor files
Actor files end with the extension *.jso*[fn::"Javascript object".]. They list a series of functions to call on a newly formed actor. Actors have a number of useful functions which are called as defined.
| function | call time |
|----------|----------------------------------------------------------|
|----------+----------------------------------------------------------|
| start | The first function called when the actor is in the world |
| update | Called once per turn |
| gui | Called on GUI draw |
| stop | Called when the actor is killed |
| gizmo | Called by the editor when the entity is selected |

var act2 = act1.spawn("hello.jso");
```
#+end_src
#+end_scholium
### Actor configuration
*** Actor configuration
Actors can be created using an optional configuration file. A configuration file is one of any accepted data types. Currently, JSON or [[https://www.crockford.com/nota.html][Nota]]. Configuration files are loaded after an actor's script file, overwriting any defined values on it.
!!! scholium
#+begin_scholium
Add a name for the actor to take on using a configuration file named *hello.json*.
```
#+begin_src
{
"name": "Actor 1"
}
```
#+end_src
Now create *hello.jso* to use it.
```
#+begin_src
this.start = function() { console.log(`I, ${this.name}, have been created.`); }
```
#+end_src
#+end_scholium
## Entities
** Entities
Game worlds are made of entities. Entities are a type of actor with a number of useful properties. Entities can only be created on the actor named *Primum*[fn::See the Primum Mobile]. The Primum is the outermost actor with a physical space. While Actors are more abstract, Entities exist in a definite space, with a position, rotation, and so on. Entities can respond to physics and play sounds. Anything which can be thought of as having a position in space should be an entitiy.
!!! scholium
#+begin_scholium
The first and most masterful entity is the Primum. The Primum has no components, and its rotation and position are zero. It defines the center of the game.
#+end_scholium
In editor mode, when an entity moves, all of its *padawans* also move.
@ -148,26 +192,26 @@ When the game is actively simulating, this only holds if there are physical cons
Prosperon automatically generates physical pin constraints between objects with the appropriate physical properties.
### Adding Components
*** Adding Components
Entities can have *components*. Components are essentially javascript wrappers over C code into the engine. Scripting is done to set the components up on entities, after which most of the work is done by the C plugin.
!!! scholium
#+begin_scholium
For example, to render an image, set up a *sprite* component on an entity and point its path to an image on your harddrive.
```
#+begin_src
var ent = Empyrean.spawn();
var spr = ent.add_component(component.sprite);
spr.path = "image.png";
```
Put that into your config file and run `prosperon`. You should see the contents of "image.png" on the screen.
#+end_src
Put that into your config file and run ~prosperon~. You should see the contents of "image.png" on the screen.
Try using an animated gif. Prosperon has native support for gif animations!
#+end_scholium
Components only work in the context of an entity. They have no meaning outside of a physical object in the world. They have no inherent scripting capabilities.
While components can be added via scripting, it is easier to add them via the editor, as we will later see.
### Ur system
*** Ur system
The ur[fn::A German prefix meaning primitive, original, or earliest.] system is a prototypical inheritence system used by the actor files. When actor files are loaded, they are stored as an ur. An *ur* holds a list of (text, config) required to create an entity.
When prosperon starts, it searches for urs by name. Any file ending in ".jso" or ".json" will be interpereted as an ur, with same named jso and json being applied as (text, config) for an ur. A jso or json alone also constitute an ur.
@ -181,13 +225,14 @@ An ur can also be defined by a json file. If an ur is found, it takes predecent
Any ur file with this sort of json creates an ur which can be created in the game. A file named "box.ur" will be ingested and be available as "ur.box". When saving differences, it creates a json file with the same name as an ur (in this case, "box.json").

Create an ur from the *hello* files above, and then spawn it.
```
#+begin_src
ur.create("hello", "hello.jso", "hello.json");
Primum.spawn(ur.hello);
```
#+end_src
When creating an actor from source files, all of its setup must take place. In this example, the setup happens during *ur.create*, and spawning is simply a matter of prototyping it.
#+end_scholium
This method allows high composability of game objects.
@ -195,45 +240,45 @@ If an entity is created without an ur, is ur is defined as its given text and da
Objects can be composed on the fly by stringing together urs. For example, a "2x.json" might define scale as 2x. Then, you can create a goblin with `ur.goblin`, or a large goblin with `ur.goblin.2x`. This creates a goblin object, and then applies the 2x scripts and jsons onto the object.
### Urs in game
*** Urs in game
Each ur has the following fields.
| field | description |
|-----------|-------------------------------------------------------------|
|-----------+-------------------------------------------------------------|
| instances | An array of instances of this ur |
| name | Name of the ur |
| text | Path to the script file |
| data | Object to write to a newly generated actor |
| proto | An object that looks like a freshly made entity from the ur |
An *ur* has a full path given like `ur.goblin.big`. `goblin` and `big` can both possibly have a *.jso* script as well as a *data* file.
An *ur* has a full path given like ~ur.goblin.big~. ~goblin~ and ~big~ can both possibly have a *.jso* script as well as a *data* file.
When `goblin.big` is created, the new object has the `goblin` script run on it, followed by the `big` script. The `data` fields consist of objects prototyped from each other, so that the `__proto__` of `big.data` is `goblin.data`. All fields of this objects are assigned to the `big goblin`.
When ~goblin.big~ is created, the new object has the ~goblin~ script run on it, followed by the ~big~ script. The ~data~ fields consist of objects prototyped from each other, so that the ~__proto__~ of ~big.data~ is ~goblin.data~. All fields of this objects are assigned to the ~big goblin~.
The unaltered form of every ur-based-entity is saved in the ur's `proto` field. As you edit objects, the differences between how your object is now, compared to its `ur.proto` is a list of differences. These differences can be rolled into the `ur`, or saved as a subtype.

### Prototyping Entities
*** Prototyping Entities
Ur types are the prototype of created entities. This makes it trivial to change huge swathes of the game, or make tiny adjustments to single objects, in a natural and intuitive way. When a value is changed on an entity, it is private. When a value is changed on an ur, it propogates to all entities. Values cannot be added or removed in subtypes.
Entities all have the following functions to assist with this:
| function | use |
|---------------|---------------------------------------------|
|---------------+---------------------------------------------|
| clone(parent) | Create an entity prototyped from the parent |
| dup(parent) | Create an exact duplicate of the parent |
| revert() | Removes all local changes on the entity |
Speaking of practical experience, is best for ur prototype chains to be shallow.
### Spawning
*** Spawning
Actor data and ur types can remember which entities were contained in it when saving. They are stored in the *objects* field. When an entity with an *objects* field is spawned, it spawns all of the objects listed in turn.
When an entity is spawned, it is addressable directly through its master entity. Its name is generated from its file or ur type name.

Assets can generally be used simply with their filename. Assets can be modified with a sidecar file named *filename.asset*, so, a file `ball.png` can have additional parameters through its `ball.png.asset` file.

Later, if the it is decided for the bumper to have a unique score sound, a new /score.wav/ can be placed in its folder and it will work without changing any code.

### Ur auto creation
*** Ur auto creation
Instead of coding all the ur type creation by hand, Prosperon can automatically search your project's folder and create the ur types for you. Any /[name].jso/ file is converted into an ur with the name. Any /[name].json/ file is then applied over it, should it exist. If there is a /.json/ file without a corresponding /.jso/, it can still be turned into an ur, if it is a valid ur format.
Folders and files beginning with a '.' (hidden) or a '_' will be ignored for ur creation.

## Input
** Input
Input is done in a highly generic and customizable manner. *players* can take control of any object (actor or otherwise) in Prosperon, after which it is referred to as a *pawn* of a player. If the object has a defined *input* object, it is a valid pawn. One player can have many pawns, but each pawn may have only one player.
Pawns are added as a stack, with the newest ones getting priority, and handled first. It is possible for pawns to block input to lower pawns on the stack.
```
#+begin_src
/newest/
car <== When a key is pressed, this is the first pawn to handle input
player
ui <== /block/ is set to true here, so editor recieves no input!
editor
/oldest/
```
#+end_src
The default player can be obtained with `Player.players[0]`. Players are all local, and the highest number is determined by platform.
The default player can be obtained with ~Player.players[0]~. Players are all local, and the highest number is determined by platform.
The *input* object defines a number of keys or actions, with their values being functions.
### Editor input
*** Editor input
The editor input style defines keystrokes. It is good for custom editors, or any sort of game that requires many hotkeys. Keystrokes are case sensitive and can be augmented with auxiliary keys.
| symbol | key |
|--------|-------|
|--------+-------|
| C | ctrl |
| M | alt |
| S | super |
```
#+begin_src
var orc = Primum.spawn(ur.orc);

orc.inputs['C-a'] = function() { ... }; /* Control-a */

```

## GUI
** GUI
Game GUIs are written by registering an entity's *gui* property to a function.
The GUI system which ships with Prosperon is called *MUM*. MUM is a declarative, immediate mode interface system. Immediate to eliminate the issue of data synchronization in the game.
All GUI objects derive from MUM. MUM has a list of properties, used for rendering. Mum also has functions which cause drawing to appear on the screen.
## Physics
** Physics
Prospeorn comes with the [[https://chipmunk-physics.net][Chipmunk]] physics engine built in. It is a fast, stable physics solution. All entities are assumed to be physics based objects, and components can be added to them to enable more physics features.
* Editor Tour
Prosperon's visual editor is an assistant for the creation and editing of your game entities and actors. In the editor, all ur types are loaded, and assets are constantly monitored for changes for hot reloading.
To initiate it, execute `prosperon`.
To initiate it, execute ~prosperon~.
## Editing entities
** Editing entities
The desktop is the topmost entity that exists in the editor. Instead of editing specific files, you simply load them into your desktop, and go from there. This makes it easier to see two different entities simultaneously so you can ensure changes to one are congruous with the vision for the others.
The main editor view is made up of entities. Each entity can have a number of components attached to it. When an entity is selected, its name, position, and list of components are listed.

## The REPL[fn::Read-eval-print loop]
** The REPL[fn::Read-eval-print loop]
The REPL lets you poke around in the game. It makes iteration and experimentation fast, fun, and easy.
The symbol `$` references the current REPL entity. If no entity is selected, the REPL entity is the currently edited one. Otherwise, it is the selected entity, or group of entities, as an array.
The symbol ~$~ references the current REPL entity. If no entity is selected, the REPL entity is the currently edited one. Otherwise, it is the selected entity, or group of entities, as an array.

The REPL is a powerful tool for editing your game. Arbitrary code can be ran in it, meaning any esoteric activity you need done for your game can be done easily. Commonly used functions should be copied into your /editorconfig.js/ to be called and used at will.
## Playing the game

## Script Editor
** Script Editor
Prosperon comes with an in-engine script editor. It implements a subset of emacs, and adds a few engine specific features.
### Syntax coloring? ... nope!
*** Syntax coloring? ... nope!
The editor that ships with Prosperon has *context coloring*, which is a good deal more useful than syntax coloring.
## Debugging
** Debugging
Debugging functions are mapped to the F buttons, and are available in any debug build of the game. Pressing the specified key toggles the feature; pressing it with /alt/ shows a legend for that feature.

** Converting assets
Images, videos, and sounds, are converted to assets most suitable for the target platform. This may be for speed or simple compatability. *You do not need to do anything*. Use your preferred asset types during production.
## Packing into a CDB
** Packing into a CDB
A *cdb* is known as a "constant database". It is a write once type of database, with extremely fast retrieval times. Packing your game into a cdb means to create a database with key:value pairs of the filenames of your game. The Prosperon executable is already packed with a core cdb.

// DEAR IMGUI COMPILE-TIME OPTIONS
// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
//-----------------------------------------------------------------------------
// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
//-----------------------------------------------------------------------------
// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
// Call IMGUI_CHECKVERSION() from your .cpp file to verify that the data structures your files are using are matching the ones imgui.cpp is using.

// This is a slightly modified version of stb_rect_pack.h 1.01.
// Grep for [DEAR IMGUI] to find the changes.
//
// 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.

sokol_memtrack.h -- memory allocation wrapper to track memory usage
of sokol libraries
Project URL: https://github.com/floooh/sokol
Optionally provide the following defines with your own implementations:
SOKOL_MEMTRACK_API_DECL - public function declaration prefix (default: extern)
SOKOL_API_DECL - same as SOKOL_MEMTRACK_API_DECL
SOKOL_API_IMPL - public function implementation prefix (default: -)
If sokol_memtrack.h is compiled as a DLL, define the following before
including the declaration or implementation:
SOKOL_DLL
USAGE
=====
Just plug the malloc/free wrapper functions into the desc.allocator
struct provided by most sokol header setup functions:
sg_setup(&(sg_desc){
//...
.allocator = {
.alloc_fn = smemtrack_alloc,
.free_fn = smemtrack_free,
}
});
Then call smemtrack_info() to get information about current number
of allocations and overall allocation size:
const smemtrack_info_t info = smemtrack_info();
const int num_allocs = info.num_allocs;
const int num_bytes = info.num_bytes;
Note the sokol_memtrack.h can only track allocations issued by
the sokol headers, not allocations that happen under the hood
in system libraries.
