  Hi lasmus, and welcome here!
  
  As for your problem, you need to get the current animation frame's graphic, not the base one. So instead of:
  

  orxGRAPHIC *pstGraphic;
  
  // Gets its graphic object
  pstGraphic = orxOBJECT_GET_STRUCTURE(pstIcon, GRAPHIC);
  

  
  Try something like:
  

  orxGRAPHIC     *pstGraphic;
  orxANIMPOINTER *pstAnimPointer;
  
  // Gets animation pointer
  pstAnimPointer = orxOBJECT_GET_STRUCTURE(pstIcon, ANIMPOINTER);
  
  // Valid?
  if(pstAnimPointer)
  {
    // Gets current anim data
    pstGraphic = orxGRAPHIC(orxAnimPointer_GetCurrentAnimData(pstAnimPointer));
  }
  else
  {
    // Gets base graphic
    pstGraphic = orxOBJECT_GET_STRUCTURE(pstIcon, GRAPHIC);
  }
  

  
  Let me know if it works!

  Thanks for the help!
  
  Did not get it to work properly yet.
  
  If I understand correctly I should do this for every frame of the animation? Maybe im still missing something

  Yes, you need to call that every frame, in an Update function, for example.
  
  Can you give me more details about what didn't work?

  Hi!
  
  Now I'm calling the scaling function from update function and at first animation is flickering (its like showing up in two different positions at the same time. ) and after about one cycle of animation it shows correctly? I dont know is that explained correctly. Maybe its just something that I dont understand. Can you help

  Interesting! ^^
  
  Would you mind posting your code/config here or send me all your files by email (my address is in the README file)?
  
  I'm pretty sure it'll be very fast to fix but it's hard to say what it is without access to your code/config.

  Ok heres something
  INI-file:

  [Object]
  Graphic = ObjectGraphic
  TextureSize = (295, 246, 0)
  Position = (-0.375, 0.15, 0.0001)
  ParentCamera = Camera
  UseParentSpace = true
  Pivot = (147.5, 246, 0) ; bottom center
  Scale (0.00078125, 0.0010416666667)
  AnimationSet = ObjectAnimationSet
  

  
  Creating object and setting animation:

  void Analysis::Init()
  {
    object_ = orxObject_CreateFromConfig("Object"); 
    orxObject_SetCurrentAnim(object_, ObjectIdleAnimation);
  }
  

  
  Generating objects according to percentage:

  void Analysis::GenerateObject(const orxCHAR* chord, orxOBJECT* object)
  {
    //Make animal graphics to analysis view
    animPointer = orxOBJECT_GET_STRUCTURE(object, ANIMPOINTER);
    
    if(animPointer)
    {
        object_graphic_ = orxGRAPHIC(orxAnimPointer_GetCurrentAnimData(animPointer));
    }
    else
    {
      object_graphic_ = orxOBJECT_GET_STRUCTURE(object, GRAPHIC);  
    }
    
    if(object_graphic_)
    {
      
      orxFLOAT  percentage, fShift;
      orxVECTOR vPivot, vSize, vOrigin;
      
      //Get chord percentage achieved  
      percentage = chord_percent_achieved[chord]; //gets value for example 0.25f
      
      // Pushes its section
      orxConfig_PushSection(orxObject_GetName(object));
      
      orxConfig_GetVector(texturesize, &vSize);// texturesize = "TextureSize"
      orxConfig_GetVector(origin, &vOrigin);//origin = "Position"
      orxConfig_GetVector(pivot, &vPivot);//pivot = "Pivot"
  
      // Pops config section
      orxConfig_PopSection();
       
      fShift = vSize.fY * (orxFLOAT_1 - percentage);
         
      vOrigin.fY += fShift;
      vSize.fY -= fShift;
      vPivot.fY -= fShift;
      		
      orxGraphic_SetPivot(object_graphic_, &vPivot);
      orxGraphic_SetOrigin(object_graphic_, &vOrigin);
      orxGraphic_SetSize(object_graphic_, &vSize);
    } 
  }
  

  
  Then calling that in update function constantly

  void Analysis::Update(const orxCLOCK_INFO *clock_info)
  {
    GenerateObject("Chord", object_);
  }
  

  
  Hope that has some use if I dont call the GenerateObject function animation works like its supposed to with full image.

  Mmh, beside what are probably typos in the config section (only 2 values for Scale and no = sign) the code looks good.
  
  Would you mind sending me somewhere a working example of the issue so that I can trace and see what's going on? I won't publish your code, of course, but if you'd rather not send it, maybe a minimal working set showing the issue then?
  
  Thanks in advance!

  MMh, just in case, all your graphics have the same size/coordinates? Also, how often is your Update() method called? Every frame?

  Hi, Haven't yet sent you anything try to get you somekind of version thats doing that thing.
  
  Answers to those questions: All the frames are same sized and update() is called more then once for every frame.

  No worries! Thanks for the details but I'm afraid I'll still need to trace the code to give you a reason of why it's not working.
