Hi, I have a few problems with Cinema updating some events.

- Button update: I've got a button which adds an additional entry in my tag's GUI. The first time it is pushed a new entry appears, but when further pushing it nothing happens, unless I click the tag icon again. Apparently the GetDDescription method does not get called. How do I solve this? Am I allowed to call GetDDescription by myself? And what do I have to place in for LONG &flags;?

- Time update: I have a for-call and in each transition the current time is set one frame forward which works correctly. But my objects' positions do not get updated for each frame:

for (long i = 0; i<frames; i++){
     GePrint ("for");
     time = BaseTime (i, docFps);
     PosOrigin = origin->GetPos();
     PosTarget = target->GetPos();
...
}

Moreover they always have the coordinates of the last frame, even if I don't include the last frame in the for-call.

Any ideas?

Thanks

Ok, second problem solved. Thx to

time = BaseTime (i, docFps);
     doc->SetTime (time);
     doc->AnimateDocument (NULL, FALSE, TRUE);
     EventAdd();

But I still need a solution for the first problem... So what do I have to insert as the third parameter "LONG &flags;" in GetDDescription?

I am not sure why it is not working for you without having a look at your source. Here a working example, it's a tag where you can add BOOL description elements with a button.

Thx very much. I didn't realise you have to change a description element to call GetDDescription. So I used a class variable as a counter so it didn't work.

The counter is not a description element. I just stored it in the object's container's sub-container to have it automatically saved with the scene. otherwise I would have to use Write/Read() functions.
