[AS3] Bug of the Tween class?

Similar Questions

• Failure of the Tween class

  Hello

  I was looking for help with the tween class because I have a strange problem. I work with AS3, when I test my project, sometimes the Tween fails, sometimes it works. It is really strange, I don't know why. The animation stops before the end point. The more strange to me is why sometimes it works and sometimes not?

  My code becomes a little complex, so I tried to do the same process in a simple model, and the result was the same, I launched the model several times, 5 or 3%, the animation ends before the correct end point. Someone with the same problem?

  Thanks in advance!

  Henrique.

  It sounds as if you are either running in a "name collision" or the interpolation is GCed before completion - this can happen if you use a simple line like:

  var Tween = new Tween (...);

  ... used repeatedly (which is soon), or when something like that is placed in a closure of the method.

  Please post the code for debugging more

• Bug in the accessor class data member with name return

  Noticed a small bug in creating data classes accessor member.

  If you have an in the variable title carridge return the vi it creates will not save.

  You do not have to set two things for each control. By default if you show the legend that is the same as the lable. You only need to change and then only for those on the FP.

• Small problem with the tween class?

  Hey everyone, I have a site that incorprerates several different interpolations, interpolation, running on a timer in the main movie(scrolling text), another developed with a button click (scrolling images) in a film that is loaded into the main movie. My problem is that tweens sometimes freeze, especially the scrolling text and from time to time, random images, interpolation of images scroll freezes. I should mention that I have several different EventListeners in the background to mouse clicks, and I have small (15 k) SWFs loaded into the film every 3.5 seconds. If anyone knows why the tweens freeze sometimes? could it have something to do with the loading and the EventListeners, or I have to live with?

  Thank you for reading and suggestions that you may have;

  
  The draft of the site is www.sunnysideosc.ca (select Gallery > pictures)

  Interpolations of freezing is usually caused by the instance of Tween getting the garbage collector. You must have the persistence of a reference to the Tween to prevent it of to GC would be. In other words, if you do this:

  new Tween(obj,'x',etc...)
  

  While Tween will get destroyed the tracks of time following GC. Instead, follow these steps:

  tween = new Tween(obj,'x',etc...)
  

  steerage "would be a property of the object in scope when the Tween is created.

  Also, you can create the Tween instance once at the beginning and assign to a property and use Tween.continueTo () to make the animations.

• Rebound of the Tween class

  Hello
  I try to use the class tween to drop something. It works very well. But how can I detect at what
  time it bounces on the ground? Because when it hits the ground, I want to start a function.
  
  And in my solution, I used a onEnterFrame, but it triggers the function for many.
  Is there a better way to detect where ball you bounces and strikes the ground?
  
  
  
  

  Use the method your tween onMotionChanged and check a hitTest with the ground.

• [as2] Make a Tween without using the tween class, take 2

  Hello. The previous topic was allowed to use with settings that made a square only.

  If you try to make a clip trip along a diagonal rectangle within 90 seconds, the video made a few curves.

  Any help?

  Thank you

  the code I gave before induces no curve.  but because flash rounds the positions of the object to the pixel the most proche.05 you can see an accumulation of rounding errors if you use some settings and you are very picky about the position of the object.  If this is the case, use the following in order to avoid the accumulation of rounding errors:

  function initTweenF(mc:MovieClip,_x1:Number,_y1:Number,_x2:Number,_y2:Number,_sec:Number):Void {}
  var freq:Number = 70;
  clearInterval (mc.tweenI);
  MC.x = x 1;
  MC.y = y1
  Mc.x = MC._x;
  Mc.y = MC._y;
     
  mc.tweenI = setInterval (tweenF, freq, mc, (x 2 - x 1) * freq /(1000*sec), (y2 - y1) * freq /(1000*sec), x 2, y2);
  }
  function tweenF(mc:MovieClip,_xInc:Number,_yInc:Number,_x2:Number,_y2:Number):Void {}
  MC.x += xInc;
  MC.y += yInc.
  Mc.x = MC._x;
  Mc.y = MC._y;
  If (Math.abs (mc._x - x 2)
  MC._x = x 2;
  MC._y = y2;
  clearInterval (mc.tweenI);
  }
  }

• syntax question (maybe the pros for the Tween class?)

  I posted it earlier, but no one answered. Maybe my post was a bit confusing. I'll try again.
  
  Here is the code (> comboFunc is the problem of children):
  
  var tweenType = [_root.tweenOptionsComboBox.selectedItem.data];
  var easeType = [_root.easeOptionsComboBox.selectedItem.data];
  var comboFunc = [tweenType + easeType];
  This.Tween = new Tween (this.ring, _xscale, comboFunc, 0,100,5, true);
  
  Basically, there are two drop-down menus of the comboBox on the root. Lists all the options for Tween (Regular, Bounce, elastic...) and all options for speeding up (easeIn, easeOut...) How can both dynamically together without a long switch statement...
  
  any ideas appreciated.
  
  Thank you

  then it is a limitation of the combobox. It cannot process data referring to a function.

  to remedy this, create your own combobox.

• [as2] Make a Tween without using the tween class

  Hello.

  Is it possible to make a clip start at a given x and there point and ends at another x's point, in 90 seconds?

  I ve done a lot of code, but I m not getting a good result.

  The main problem is, I want the music to travel along the straight line. And by this code under the film clips "b" makes a few curves.

  Here´s what I ve done.

  'p' is point movie clip

  'b' is ball movie clip

  full time = 90000;
  _currentTime = full time;
  oldTime = undefined;
  onEnterFrame = function () {}
  If {(County)
  _currentTime = _currentTime-(Math.abs (oldTime - getTimer ()));
  }
  County = true;
  oldTime = getTimer();
  speedX = (p._x-b._x)/((_currentTime*24)/1000);
  Fast = (p._y-b._y)/((_currentTime*24)/1000);
  b._x += speedX.
  b._y += fast;
  If (b._y > = p._y) {}
  do something

  }
  };

• Bug of the Sound class

  I posted this earlier and got no answer, so please help if you can:
  
  for flash.media.Sound, is the description of the function of reading:
  public void play(startTime:Number_=_0,_loops:int_=_0,_sndTransform:SoundTransform_=_null):SoundChannel
  
  and for the first parameter:
  startTime:Number (default = 0) - initial position in milliseconds at which playback should begin.
  
  The first parameter, startTime, doesn't seem to work at all. I tried all values greater than about 26 will cause the sound to send within a few milliseconds soundComplete event instead of play the file at all.
  
  What is the problem?
  

  Since the Beta 3, this seems to work fine.

• Failed to load the external class?

  I use the tweener class in this file very well. But when I try to use the sound Manager class, I can't seem to load why? Here is my flash code to follow at the beginning of the class... Any ideas? Thank you... I get type not found...

  I thjink you import the class with a fake name AS3 is case sensitive and so
  import com.richardsongraphics.soundmanager;

  is not the same as

  import com.richardsongraphics.SoundManager;

  Please check once again if you have used the same line for the import of this class.

• Problem with the tweens and HitTest

  Hi guys,.

  I have a problem with generated code tweens and HitTest.

  But first of all the info from backgeround. I have a couple of points. They differ by the scale and are generated from a single movieclip. The idea is that a larger ist value to the central position of the scene.

  Others come from the border of the outdoor stage and are heading to the central position. This is done by using the Tween class.

  What needs to happen, is that they stop exactly on the border of the points that are already in the middle. In the beginning, there is just the main, big point, which was manually placed in the middle. When the first point has reached its position, the bounding box should include this new dot.

  I use the hitTestObjects method to stop the Tweeing.

  The problem is that there are 80% chance that the points have gaps or overlapping each other. Any ideas on that?

  Thank you for every response!

  It's hitTesting Code in the main class:

  public function hitTesting(e:Event):void{
  
                                for(var i:int=0; i<dotArray.length;i++){
                                                    for(var j:int=i+1; j<dotArray.length;j++){
                                                              if(dotArray[i].hitTestObject(dotArray[j])==true){
                                                                        dotArray[i].stopTweening();
                                                                        dotArray[j].stopTweening();
                                                              }
                                                    }
                                }
  

  This is the code for a simple point

  public function Dot(anchorArray:Array,randomX:int,randomY:int,scaleVal:Number,first:Boolean, delayVal:Number, lastElement:Boolean, values:Array) {
       this.x=randomX;
       this.y=randomY;
       this.scaleX=this.scaleY=scaleVal;
       this.valueName=values[0];
       this.countValue=values[1];
       this.gRanking=values[2]
       this.lastElement= lastElement;
       this.first=first;
  
  
        if(!first){
             this.xTween = new Tween(this, "x", None.easeNone, this.x, anchorArray[0], 20, false);
             this.yTween = new Tween(this, "y", None.easeNone, this.y, anchorArray[1], 20, false);
             this.xTween.start();
             this.yTween.start();
        }
  }
  
  public function stopTweening():void{
    if(!first){
        if(lastElement)
             parent.removeEventListener(Event.ENTER_FRAME, parent.hitTesting);
  
        xTween.stop();
        yTween.stop();
  
        }
   }
  

  OK guys,

  found a solution. It seems to be, that the construction in the HitTest feature is inaccurate for my problem.

  I found a better implementation here.

  Tanks for reading.

• Using Tween class

  Hello
  
  I'm working on the understanding of the Tween class and I was wondering if someone could explain something to me. I wrote the code below in the expectation that fade (1. jpg) image and then fade out. In fact what is happening, is that the image only fainted. For some reason, it does not fade, but seems just.
  
  Could someone please explain why this is so and how can I do to get the desired fade, fade out?
  
  Thank you in advance.
  
  Import mx.transitions.Tween;
  Import mx.transitions.easing. *;
  
  createEmptyMovieClip ("test_mc", getNextHighestDepth);
  loadMovie ("1.jpg", test_mc);
  
  var photoFadeIn:Tween = new Tween (test_mc, "_alpha", Strong.easeIn, 100, 0, 1.5, true ");
  var photoFadeOut:Tween = new Tween (test_mc, "_alpha", Strong.easeIn, 100, 0, 1.5, true ");

  My bad: onMotionFinished

• Tween class and using variables

  I can't using a variable as the 1st parameter in the Tween class.
  f2_mc is the name of the element to be interpolated
  on {(press)
  _Global.mcName = MovieClip;
  _Global.mcName = f2_mc;
  _root.setXposition ();
  }
  function (setXposition) {}
  var moveIn:Object = new Tween (_global.mcName, "_x", Strong.easeOut, 600, 50, 2, true);
  moveIn.onMotionFinished = function() {}
  }
  }

  Hey chop, maybe you should write these declarations like this:

• Unreliable Tween class?

  1 of 4 function calls of a results MouseEvent in the 'stuck' somewhere in the Tween MovieClip. As if it did not. Everyone knows this? Or am I using the wrong Tween class?
  
  addEventListener (MouseEvent.CLICK, tweenStyle)
  
  private void tweenStyle(event:Event):void
  {
  var scaleYTween:Tween = new Tween (MovieClip, "scaleY", Strong.easeOut, 0, 1,.5, true);
  }
  
  

  Just press it:

  Note: Consider variable scope by using the Tween class. If a Tween is created in a function, it is important that the scope of the variable exists beyond the function itself. If a Tween is stored in a local scope variable, ActionScript garbage collection removes the fuller interpolation of the function, which will be probably before interpolation had even begun.

  Yes, after having done my members of the class Tweens, no problemo!

• Tween class problem

  well I can't really see what's wrong. appears to be an error in the flash, but maybe theres a rule im does not suite or something...
  my code:
  
  (main timeline)
  
  Import mx.transitions.Tween;
  Import mx.transitions.easing. *;
  
  mcNum = 1;
  mcStart = 880;
  mcFinish = - 30;
  owner of the image
  var inter = setInterval (transition, 500);
  
  transition() {} function
  mcName = 'line' + mcNum;
  trace (mcName);
  mcNum ++;
  mcStart = mcStart + 40;
  mcFinish = mcFinish + 40;
  var twMoveClip:Tween = new Tween (mcName, Strong.easeOut, mcStart, mcFinish, 2, true);
  
  If {(mcNum > 5)
  clearInterval (inter);
  }
  }
  Stop();
  
  the problem is that nothing moves. the track of "mcName" comes up with "line1, line2... line 5" as it should. However if I change mcName of > 'line' + mcNum < to just > line1 <. He calls line1 and makes it move. It is not not my expected results because none of the others move... ive been at this for hours. and it seems that the tween class will not work when calling on a variable that was added 2 other variables or variable and a number.
  
  Please help someone :(
