====== MooEngine ======
===== Overview =====

{{:mooengine:icon.png?nolink}}

MooEngine was my attempt at creating a 100% scriptable game engine. I was able to integrate all the necessary features by creating a new scripting language called MooScript.

The basic features of MooScript are:
  * syntax similar to c, only less complicated
  * built-in datatypes: bool, int, float, string
  * object-oriented scripting language including inheritance and the like
  * loops, vectors, maps...
  * one thread per script

The obligatory Hello World code:
<code>
log("Hello World")
</code>
Not very exciting, right? :)

Let's make it slightly more interesting:
<code>
main : 1000
{
  log("Hello World")
}
</code>
The (optional) main function is now automatically called every 1000ms.

Same example, but this time the "Hello World" string is generated by a function:
<code>
Function getMessage() : String
{
  return "Hello World"
}

main : 1000
{
  log(getMessage())
}
</code>

If you ever wanted to simulate a cow:
<code>
Function getMoo(Integer num) : String
{
  return "M" + "o" * num
}

main : 1000
{
  log(getMoo(2 + rand(10)))
}
</code>
The output will be:
<code>
Moooo
Moo
Moooooo
...
</code>

Rather straightforward. Using classes is not very complicated either:

<code>
Class Animal
{
  String name
  
  Method talk()
  {
    log("I can't talk")
  }
}

Class Cow : Animal
{
  Bool happy = TRUE
  
  // constructor
  Cow(String n)
  {
    name = n
  }
  
  Method talk()
  {
    if (happy)
      log(name + " 3:-)")
    else
      log(name + " 3:-(")
  }
  
  Method tip()
  {
    happy = FALSE
  }
}

Cow cow1("MadCow"), cow2("BadCow")

cow1.talk()
cow2.tip()
cow2.talk()
</code>
The output will be:
<code>
MadCow: 3:-)
BadCow: 3:-(
</code>

Some of the more interesting features are:
  * inter-process communication
    * c++ <-> script: synchronized variables
    * c++ -> script: call methods
    * script -> cpp: emit signals
    * script <-> script: call methods and access variables
  * many built-in functions (maths, string manipulation, file operations)
  * create and manage GUI elements: windows, widgets
  * create and manage arbitrary 2D scenes
  * create and manage arbitrary 3D scenes (complete with entity handling, keyboard and mouse input, ...)
  * create and modify images

More highlights:
  * dynamically load/unload scripts
  * scripts share common scene graph for quick rendering
  * integrate 2D/3D scenes in widgets using offscreen rendering
  * HTTP client: automatically download remote content
  * HTTP server: dynamic webpages using MooScript
  * ...
