I am having an issue with very jerky animations once it is published. I am using Flash Develop for a non-Starling target.

When I publish, the resulting .swf plays all the slow animations with jerky movement, as if it is missing frames or it's trying to catch-up.

However, when publish my Starling files, it works fine. I must have a setting I am missing on the Spine EXPORT or something.

Any help is much appreciated! ChzBoi

Hi badlogic - correct, just plain old AS3. My understanding is that there are only 2 AS3 Runtimes : normal and Starling. I've been using the Starling without issues, but this current project needs to be done in normal AS3.

I've double checked all I can think of, yet, the slow (15 sec idle animation) stutters, jerks, lags when I call for the animation to play:

var tmpTE:TrackEntry = SK_VTop_Fauna.state.setAnimationByName(0, "IDLE1", true);

I've also set the quick animations (2 seconds or less) with

tmpTE.timeScale

value set to some small value - they also will do the stutter/jerky movement.

Very perplexing. :wonder:

Thanks badlogic for the info - I did make a few simple tests. Any slow animation has this issue, debug or release. My entire code is 45 lines long, which I have copied below.

I am thinking this has gotta be a FlashDevelop publish setting I am missing.

UPDATE : Tried this same code in the Animate IDE - still stutters.

package
{
   import spine.animation.TrackEntry;
   import flash.display.Sprite;
   import spine.flash.SkeletonAnimation;

   import spine.*;
   import spine.animation.AnimationStateData;
   import spine.atlas.Atlas;
   import spine.attachments.AtlasAttachmentLoader;
   import spine.flash.FlashTextureLoader;

   [SWF(width = "1000", height = "500", frameRate = "60", backgroundColor = "#dddddd")]
   public class Main extends Sprite {
      

  [Embed(source = "/AS3_Speed_Stutter_TEST.atlas", mimeType = "application/octet-stream")]
  static public const AS3_Speed_Stutter_TESTAtlas : Class;

  [Embed(source = "/AS3_Speed_Stutter_TEST.png")]
  static public const AS3_Speed_Stutter_TESTAtlasTexture : Class;

  [Embed(source = "/AS3_Speed_Stutter_TEST.json", mimeType = "application/octet-stream")]
  static public const AS3_Speed_Stutter_TESTJson : Class;
  private var SK_AS3_Speed_Stutter_TEST:SkeletonAnimation

  public function Main() {

     var Atlas_AS3_Speed_Stutter_TEST : Atlas = new Atlas(new AS3_Speed_Stutter_TESTAtlas(), new FlashTextureLoader(new AS3_Speed_Stutter_TESTAtlasTexture()));
     var JSON_AS3_Speed_Stutter_TEST : SkeletonJson = new SkeletonJson(new AtlasAttachmentLoader(Atlas_AS3_Speed_Stutter_TEST));
     JSON_AS3_Speed_Stutter_TEST.scale = 1;
     var SkeletonData_:SkeletonData = JSON_AS3_Speed_Stutter_TEST.readSkeletonData(new AS3_Speed_Stutter_TESTJson());
     var StateData_AS3_Speed_Stutter_TEST : AnimationStateData = new AnimationStateData(SkeletonData_);
     
     
     SK_AS3_Speed_Stutter_TEST = new SkeletonAnimation(SkeletonData_, StateData_AS3_Speed_Stutter_TEST);
     SK_AS3_Speed_Stutter_TEST.x = 500;
     SK_AS3_Speed_Stutter_TEST.y = 225;         
  
     var tmpTE:TrackEntry;
     tmpTE = SK_AS3_Speed_Stutter_TEST.state.setAnimationByName(0, "IDLE1", true);

     addChild(SK_AS3_Speed_Stutter_TEST);
  }
   }
}

Sure badlogic! Here is a DropBox link to the zip file. https://www.dropbox.com/s/vzoi4o7vygxtvft/AS3_Speed_Stutter_TEST.zip?dl=0

Morning badlogic - good to know I am not losing my mind! Thanks for looking into this.

If you need me to test anything, please feel free to ask. I've tested in FlashDevelop changing the

tmpTE.timeScale

value to extreme high and low values - it seems to interpolate abruptly regardless of that setting.
