For both modes, the following applies: If the node is triggered while in the middle of a countdown,
the countdown starts again from the beginning.
The following input ports are available:
 Duration: Controls the duration of the countdown. If you set this value in the
Attribute manager, enter the duration in frames. However, if you connect, say,
a Constant node to this port, the value denes the duration time in seconds.
 Reset: If this port receives a Bool value of 1, the node’s internal counter is
reset to 0.
 Time: This port enables you to, for example, connect a Time node to the
MonoFlop. The Time node can then be used to control the speed of the
countdown.
 Trigger: This port takes a Bool value and is used for starting the
countdown.
The following output ports are available:
 Count: Outputs the total number of times that the node has been triggered.
You can reset this counter by passing a value of 0 to the Reset input port.
 Out: Outputs a Bool value of 1 if a countdown is in progress. Otherwise, the
port outputs a value of 0.
 State: If the node is currently counting down, this port outputs a decimal value
between 0.0 and 1.0 that indicates how far the countdown has progressed.
For example, if the countdown is 30% of the way through the countdown, this
port will output the value 0.3. If, on the other hand, the node is disabled, the
port outputs the value 0.
Noise
Noise values depend not only on the animation time, but also on coordinates. This enables the node
to output different values for the same frame of the animation. In this example, each point is given a
different value.
This node uses noise to generate random numbers. Four types of noise are available: Noise, Turbulence,
Wavy Turbulence and Fractal Brown Movement.
