Initializing Objects

There are two ways to set the initial values of object fields.

1. Pass in a Map of values to the initializer
2. Set values inside the onCreate method

Initializer Map 

When you pass a Map of values to the initializer, it will set any public fields that match.

class Character {

    public fields {
        name: '',
        health: 33,
        location: 'Northoros',
    }
}

// Another file
//----------------------------------

// Set new values for 'health' and 'name'
$char = Character({
    name: 'Thatia',
    health: 99,
})

$char.name      //= 'Thatia'
$char.health    //= 99
$char.location  //= 'Northoros'

onCreate Method 

You can define a method named onCreate, which is like __construct in PHP.

This 'hook' method will be called automatically after the object is created, and after the fields are initialized.

The first and only argument to this method will contain the Map passed to the initializer, or an empty Map if one was not passed in.

class Character {

    public fields {
        weapon: 'Fist',
    }

    fn onCreate($init) {
        if $init['isArcher'] {
            @.weapon = 'Bow & Arrow'
        }
    }
}

// Another file
//----------------------------------

$char = Character({ isArcher: true })

$char.weapon
//= 'Bow & Arrow'
