Question

I have been programming a command for Animate(a jsfl file), and I'm implementing something with it's Animate's own 'Export Motion as XML'.

The problem is that after exporting it, it just gives its transform informations, and I'm needing to get the sprite/frame/image change on it's motion, I have been trying to find in it's documentation about looking IF the actual frame is a keyframe, and the closest thing is frame.hasMotionPath() and frame.isMotionObject()

Now, I'm wanting informations or triggers when the keyframe got different informations about more internal frames, if it changed the image during the motion, and to what image it changed

Hi.

You can detect keyframes by using the frame.frameStart and frame.duration properties.

Anyway, I think I didn't get what exactly you want to do.

Can you elaborate more or give some example?

    What I want is: know when in the motion it change the actual image it is using

    Let's suppose that in a motion I make one symbol change its image from 'idle.png' to 'walk.png', it usually don't appear something like that

    Can i know in the motion any attribute that says what image it is current using? As I know transform attributes is possible, but I didn't find anything about the image

    Hi again.

    If I'm understanding correctly, you can use the libraryItem property.

    Say for example you have a timeline with only one layer and that there are two keyframes with one bitmap in each keyframe. The first bitmap is called idle.png in the Library and the second is called walk.png in the Library.

    You could write this:

    var doc = fl.getDocumentDOM();
    var timeline = doc.getTimeline();
    var frames = timeline.layers[timeline.currentLayer].frames;
    var current;
    var previous = null;
    frames.forEach(function(frame, index)
    {    
        current = frame.elements[0].libraryItem.name;
        
        if (previous && previous !== current)
                fl.trace("changed" + ", " + index + ", " + previous + ", " + current);
        
        previous = current;
    });

    Please let me know if this helps you.

    Regards,

    JC
