Detailed Description

Utility class that measures the elapsed time.

sf::Clock is a lightweight class for measuring time.

The clock starts automatically after being constructed.

It provides the most precise time that the underlying OS can achieve (generally microseconds or nanoseconds). It also ensures monotonicity, which means that the returned time can never go backward, even if the system time is changed.

Usage example:

sf::Clock clock;
...
Time time1 = clock.getElapsedTime();
...
Time time2 = clock.restart();
...
Time time3 = clock.reset();

The sf::Time value returned by the clock can then be converted to a number of seconds, milliseconds or even microseconds.

Member Function Documentation

◆ getElapsedTime()

Time sf::Clock::getElapsedTime ( ) const

nodiscard

Get the elapsed time.

This function returns the time elapsed since the last call to restart() (or the construction of the instance if restart() has not been called).

Returns: Time elapsed

◆ isRunning()

bool sf::Clock::isRunning ( ) const

nodiscard

Check whether the clock is running.

Returns: true if the clock is running, false otherwise

◆ reset()

Time sf::Clock::reset ( )

Reset the clock.

This function puts the time counter back to zero, returns the elapsed time, and leaves the clock in a paused state.

Returns: Time elapsed

See also: restart

◆ restart()

Time sf::Clock::restart ( )

Restart the clock.

This function puts the time counter back to zero, returns the elapsed time, and leaves the clock in a running state.

Returns: Time elapsed

See also: reset

◆ start()

void sf::Clock::start ( )

Start the clock.

See also: stop

◆ stop()

void sf::Clock::stop ( )

Stop the clock.

See also: start
