Modi

Modi is a model library that was inspired by Core Data framework on MacOS. Core principle is seperating data from code. Model definitions are stored as YAML text files and are easy to read and maintain. Using simple Python script, data is transformed into Actionscript classes that are easy to monitor.

Requirements

• Python 2.7.3
• as3yaml
• PyYAML
• jinja2

Demo example

Demo/src/Player.yaml

Player:
    name: String
    commanders: ManagedArray<Commander>
    gold:
        type: Number
        default: 0
    selectedEntity: ManagedObjectId
    mode:
        values: [idle, walk, attack] #Enum.
        default: idle

Call to a python script inside of a command line

Modi.py Demo/src/Player.yaml -o Demo/src -p Models.Player

Created source code

Utilities

ManagedObjectContext

var managedObjectContext:ManagedObjectContext = new ManagedObjectContext();
var player:Player = managedObjectContext.createManagedObject(Player);
player.name = "Burek";
var playerCopy:Player = managedObjectContext.getManagedObjectById(player.contextId) as Player;

trace(playerCopy.name); /// Burek

YAMLSerializator

var serializator:YAMLSerializator = new YAMLSerializator();
player.serialize(serializator);

var stream:FileStream = new FileStream();
stream.open(new File(destination), FileMode.WRITE);
stream.writeUTFBytes(serializator.serializeData());
stream.close();

YAMLDeserializator

var stream:FileStream = new FileStream();
stream.open(new File(destination), FileMode.READ);
var data:String = stream.readUTFBytes(stream.bytesAvailable);
stream.close();

var deserializator:YAMLDeserializator = new YAMLDeserializator();
deserializator.deserializeData(data);
player.deserialize(deserializator);

Using event listeners

player.addEventListener(_Player.ATTRIBUTE_NAME, onNameChange);
player.name = "Sirnica";

function onNameChange(e:ManagedObjectEvent):void
{
    trace(e.type); /// name
    trace(e.newValue); /// Sirnica
    trace(e.oldValue); /// Burek
    trace(e.owner); /// [object Player]
}
