Example: Start or stop wiggle at specific time

You can use any expression in place of the wiggle expression used here, to begin and end any expression’s influence at a specific time.

Apply the following expression to a property to wiggle it beginning at time 2 seconds:

  timeToStart = 2; 
  if (time > timeToStart){ 
      wiggle(3,25); 
  }else{ 
      value; 
  }

Apply the following expression to a property to stop wiggling it at time 4 seconds:

  timeToStop = 4; 
  if (time > timeToStop){ 
      value; 
  }else{ 
      wiggle(3,25); 
  }

Apply the following expression to a property to start wiggling it at time 2 seconds and stop wiggling it at time 4 seconds:

  timeToStart = 2; 
  timeToStop = 4; 
    
  if ((time > timeToStart) && (time < timeToStop)){ 
      wiggle(3,25); 
  }else{ 
      value; 
  }
