6.2. Timer — Manages the virtual time

The Timer class manages the virtual time and drives the entire animation/simulation. Everything that is animated either directly or indirectly connects to the time slot of the global Timer instance. This global timer is automatically created by the scene and can be obtained by calling the timer() method of the Scene class.

class Timer(name = ''Timer'', auto_insert = True)

name is the component name.

Timer.time

Current virtual time in seconds (DoubleSlot). This value is increased by timestep whenever the step() method is called.

Timer.timestep

The delta time step in seconds that represents one frame.

Timer.duration

The total duration in seconds of the animation/simulation.

Timer.frame

Current (fractional) frame number (as float).

Timer.fps

Current frame rate (as float).

Timer.framecount

Total number of frames of the animation/simulation (as float).

Timer.clock

This value contains the value in seconds of the real clock.

Timer.startClock()

Start the real clock.

Timer.stopClock()

Stop the real clock.

Timer.step()

Step to the next frame. This call increases the current virtual time by timestep and emits a STEP_FRAME event.
