other sensors

This part presents TimeSensor, MotionSensor, TouchSensor and MediaSensor.
KeySensor and InputSensor are already presented in previous tutorial.

TimeSensor node generates periodic values. It's a 'timer' and it is basis of most animations.
See TimeSensor documentation for more informations about it.

In this tutorial, we would create a timer.
Timer displays time since the launch of the widget.

This tutorial require:

A text node
A TimeSensor node
A function to convert time values into displayable information.

The text node:

Shape {
  appearance Appearance { material Material2D { emissiveColor 0 0 0 } }
  geometry DEF CURRENT_TIME_TXT Text {
    string [ "0" ]
    fontStyle FontStyle {
      justify [ "MIDDLE" "MIDDLE" ]
    }
  }
}

The TimeSensor node:

DEF MY_TIMER TimeSensor {
  cycleInterval 1 # Refresh timer all seconds
  loop TRUE
  isActive TRUE
}

Script to receive timer event and convert time in displayable value.
We use Math.floor() function to convert float value to integer value (See Math class documentation).

DEF SCRIPT Script {
  eventIn  SFTime   cycleTime
  eventOut MFString displayValue
  url "
  function cycleTime () {
    # cycleTime return time to start the timer (in second since application start)
    displayValue [ 0 ] = Math.floor(cycleTime);
  }
  "
}

Finally, link TimeSensor node and Script node, and link Script node and Text node:

ROUTE MY_TIMER.cycleTime  TO SCRIPT.cycleTime
ROUTE SCRIPT.displayValue TO CURRENT_TIME_TXT.string

Note:
See animation tutorials for more examples about TimeSensor.

Note:
Audio and video functionalities depend of your mobile phone.

Note:
TouchSensor node requires mobile phone with touchscreen.
Detects touch screen events on all Shapes included in the same Group in which the TouchSensor is declared.

Note:
MotionSensor node requires mobile phone with accelerometer.
Gives access to accelerometer data if available.
