Variables

Variables can hold a value of literal or object type.

Literal types are:

• Int
• Float
• Bool
• String

Variables are private. It means that only that script is aware of them, can write to them and read from them. Other scripts can't access that script's variables.

To declare a variable, use the var keyword. You also can specify the type explicitly, but it is optional — the type will be inferred from initializer.

But if you omit an initializer, you have to specify the type; the variable gets a default value for its type: numeric types 0, Bool false, String "", and object and array types default to none.

script MyScript {

    var myVariable = 42 // Int type will be inferred automatically
    var anotherVariable: Int = 100 // explicit type annotation
    var varWithDefaultValue: Int // omit initializer, will be default initialized (see above)

    fun foo() {
        myVariable *= 2
        var localVar = myVariable
    }
}

Local variables are those declared inside functions or loops and have a shorter lifetime than member (script) variables.

In addition to literals, you can declare a variable of any available object type.

script MyQuestScript: Quest {

    var player: Actor // initialized to none (same as other object and array types)

    event onInit() {
        player = Game.GetPlayer()
    }

    fun foo() {
        if player != none {
            // do some stuff with player
        }
    }
}
