Hey all,

I'm in the process of developing a .obj-based format that'll support my needs (bones/animation, etc) in a video game engine I've been working on.

How I would like to configure things would be by using markers to signify the start of a new animation (with a marker marked "end" to finish the last animation). So that brings me to my question, I'm using the COFFEE interface and I can't seem to figure out how to get to all the BaseKeys in the document (so I can check for MarkerKey and query the number of markers and the name of each). How do I get this information?

Thanks in advance!
Derek

Hi,

you need to go through all objects in the document and get their keys. Example:

var key = obj->GetFirstTrack()->GetFirstSequence()->GetFirstKey();

you can then use GetNext() to get the next key.

Awesome, thanks Designer :).

EDIT: Hrm, that seems to error out on me when I run it.

Doing
var key = op->GetFirstTrack()->GetFirstSequence()->GetFirstKey();
or
var key = op->GetFirstTrack()->GetFirstSequence();

Generate: "Incompatible values... NIL / OBJECT"

(var test = op->GetFirstTrack() works fine though).

maybe because there is no sequence yet for op? Did you check?

What do you mean by checking? As in checking in the document (I surely can't expect everything with the document to contain animation...) or within the COFFEE plugin by doing something like:

if(op->GetFirstTrack()->GetFirstSequence() == NULL) ...

Because running the above code generates that same error.

And after we figure this out I'll have to find out how to get all the keyframes between the tags. So lets say there is one animation in a file, that means two markers, the first signifying the start of the animation (probably at frame zero in this case) and another marker at the last frame of animation marked "end". Between those two I need to record each keyframe that would change the locations/rotations of any bones it applies to. (I hope that made sense).

Thanks again!

Alright, fixed that silly error by doing something a little ugly:

  
        if(op->GetFirstTrack() != NULL)  
        {  
            if(op->GetFirstTrack()->GetFirstSequence() != NULL)  
            {  
               if(op->GetFirstTrack()->GetFirstSequence()->GetFirstKey() != NULL)  
               {  
                    key = op->GetFirstTrack()->GetFirstSequence()->GetFirstKey();  
               }  
            }  
        }

Now on to the markers and all the keyframed stuff I can find for bone objects between the markers. Finding the BaseKeys is pretty easy thus far, but I'm having no luck finding the markers (none of the BaseKeys I find from going through the objects are markers). Where would the markers be stored?

Markers are unfortunately not accessible. (Neither in C++ nor C.O.F.F.E.E.) You will have to use some other way for the user to specify the interval.

Wow, I guess just another thing I can't enjoy using. Any ideas how else I can do things?

After some thought the best I can come up with is doing an animation every one-hundred frames, obviously when I load in the data I discard the time after the last keyframe in the sequence. With that I'd have to go in by hand and name (in the file I export) the animations as that's fairly important to me.
