   Currently I´m writing my own action and I would like to use a timeperiod easing (not an energyEasing) in the update method of the action.
   
   For example I would like to move all a particles from the current position to another with easing:
   
   I would use the time property as duration for the easing, but I dont know which property I can use for the counter. I could use an own one, but maybe you have a better solution.
   
override public function update(emitter:Emitter, particle:Particle, time:Number):void
{
var p:Particle2D = Particle2D(particle);
p.x = Cubic.easeOut(?????, currentX, targetX, time);

}

   The time element is just the duration of this single frame. I doubt that's what you want. More likely you want the total time passed for the effect. Your custom action may be something like this.
   
   package
{
class CustomAction extends ActionBase
{
public var effectDuration:Number;
public var targetX:Number;

public function CustomAction( target:Number, duration:Number )
{
targetX = target;
effectDuration = duration;
}

override public function update(emitter:Emitter, particle:Particle, time:Number):void
{
var p:Particle2D = Particle2D(particle);
if( !p.dictionary[this] )
{
p.dictionary[this] = {startX:p.x, distance:targetX - p.x, timePassed:0};
}
var state:Object = p.dictionary[this];
state.timePassed += time;
p.x = Cubic.easeOut(state.timePassed, state.startX, state.distance, effectDuration);
}
}
}
   
   You store particle specific data in the particle's dictionary, initializing it if it'snot set. Then add the time to the particle's time passed on each update.

   You are awesome, I tried similar but didnt work for me. This works perfect. I already worked with the dictionary and saved the origin particle position in it.
