The DelayedCall class is used to delay the invocation of a function by a given time.

See also: Juggler

Examples:

var action = () => print("Hello world!");
var delayedCall = new DelayedCall(action, 1.0);
juggler.add(delayedCall);

var action = () => print("Hello world!");
juggler.delayCall(action, 1.0);

class DelayedCall implements Animatable {

 final Function _action;
 num _currentTime = 0.0;
 num _totalTime = 0.0;
 int _repeatCount = 1;

 DelayedCall(Function action, num delay) :
   _action = action {
   _totalTime = max(delay, 0.0001);
 }

 //-------------------------------------------------------------------------------------------------
 //-------------------------------------------------------------------------------------------------

 bool advanceTime(num time) {

   num newTime = _currentTime + time;

   while (newTime >= _totalTime && _repeatCount > 0) {

     _currentTime = _totalTime;
     _repeatCount--;
     _action();

     newTime -= _totalTime;
   }

   _currentTime = newTime;

   return (_repeatCount > 0);
 }

 //-------------------------------------------------------------------------------------------------

 num get totalTime => _totalTime;
 num get currentTime => _currentTime;
 int get repeatCount => _repeatCount;

 set repeatCount(int value) {
   _repeatCount = value;
 }
