-
-*** Windows
-Copy the executable into any folder and run it. If no game is deteced, it scaffolds for you.

-*** Building
-You will need ~sokol-shdc~ in the top of your directory. Then, ~make shaders~ and ~make~. The command ~make install~ copies it to your home's ~.bin~ path.

+
+## 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                                                |

-*** 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.

+    Now create *hello.jso* to use it.
+    ```
+    this.start = function() { console.log(`I, ${this.name}, have been created.`); }
+    ```
 
-** 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.
 
-#+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

-*** 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.
 
-#+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";
-#+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!

 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.

 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.

-*** 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.

-** 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.

+// 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.
