bool

Tipo booleano incorporado.

Descripción

Boolean is a built-in type. There are two boolean values: true and false. You can think of it as a switch with on or off (1 or 0) setting. Booleans are used in programming for logic in condition statements, like if statements.

Booleans can be directly used in if statements. The code below demonstrates this on the if can_shoot: line. You don't need to use == true, you only need if can_shoot:. Similarly, use if not can_shoot: rather than == false.

var can_shoot = true

func shoot():
    if can_shoot:
        pass # Perform shooting actions here.

The following code will only create a bullet if both conditions are met: action "shoot" is pressed and if can_shoot is true.

Note: Input.is_action_pressed("shoot") is also a boolean that is true when "shoot" is pressed and false when "shoot" isn't pressed.

var can_shoot = true

func shoot():
    if can_shoot and Input.is_action_pressed("shoot"):
        create_bullet()

The following code will set can_shoot to false and start a timer. This will prevent player from shooting until the timer runs out. Next can_shoot will be set to true again allowing player to shoot once again.

var can_shoot = true
onready var cool_down = $CoolDownTimer

func shoot():
    if can_shoot and Input.is_action_pressed("shoot"):
        create_bullet()
        can_shoot = false
        cool_down.start()

func _on_CoolDownTimer_timeout():
    can_shoot = true

Descripciones de Métodos

• bool bool ( int from )

Convierte un valor int a un valor booleano, este método devolverá false si se pasa 0, y true para todos los demás valores enteros.

---

• bool bool ( float from )

Convierte un float a un valor booleano, este método devolverá false si se pasa 0.0, y true para todos los demás números reales.

---

• bool bool ( String from )

Convierte un valor String a un valor booleano, este método devolverá false si se pasa ", y true para todas las cadenas no vacías.

Ejemplos: bool("False") devuelve true, bool("") devuelve false.
