bool¶

A built-in boolean type.

Description¶

A bool is always one of two values: true or false, similar to a switch that is either on or off. Booleans are used in programming for logic in condition statements.

Booleans can be directly used in if and elif statements. You don't need to add == true or == false:

if can_shoot:
    launch_bullet()

if (canShoot)
{
    launchBullet();
}

Many common methods and operations return bools, for example, shooting_cooldown <= 0.0 may evaluate to true or false depending on the number's value.

bools are usually used with the logical operators and, or, and not to create complex conditions:

if bullets > 0 and not is_reloading:
    launch_bullet()

if bullets == 0 or is_reloading:
    play_clack_sound()

if (bullets > 0 && !isReloading)
{
    launchBullet();
}

if (bullets == 0 || isReloading)
{
    playClackSound();
}

Constructors¶

bool	bool ( )
bool	bool ( bool from )
bool	bool ( float from )
bool	bool ( int from )

Operators¶

bool	operator != ( bool right )
bool	operator < ( bool right )
bool	operator == ( bool right )
bool	operator > ( bool right )

Constructor Descriptions¶

bool bool ( )

Constructs a default-initialized bool set to false.

bool bool ( bool from )

Constructs a bool as a copy of the given bool.

bool bool ( float from )

Cast a float value to a boolean value. This method will return false if 0.0 is passed in, and true for all other values.

bool bool ( int from )

Cast an int value to a boolean value. This method will return false if 0 is passed in, and true for all other values.

Operator Descriptions¶

bool operator != ( bool right )

Returns true if two bools are different, i.e. one is true and the other is false.

bool operator < ( bool right )

Returns true if the left operand is false and the right operand is true.

bool operator == ( bool right )

Returns true if two bools are equal, i.e. both are true or both are false.

bool operator > ( bool right )

Returns true if the left operand is true and the right operand is false.
