Playthread timing

Hello all,
I've got a static shape with some animation sequences exported out as a .dts.
I am able to play these sequences, however I am interested in playing them
with some sort of "time" control. Right now the way I have it set up, the sequences
are scripted to start when a button on a custom GUI I created is pressed, but it appears
as if all all of the sequences are playing at the same time. What I'd like to have happen
is that the first sequence plays, once it is done the second one plays, when its done
the third one plays...and so on and so on. I've got 4, which some searching revealed as
some sort of ceiling.
Anyway, I could combine all the sequences into one, but in some cases I may change the
order so seperating the sequences out and calling them with script is more desirable.
The only thing that I could think of was to use the "schedule" command, but thought there
me be a more direct way I am not aware of. (e.g. I didn't know if there was a way to tie a
function call to a seuquence once it has reached its final frame).
Thanks in advance for any insight into this!!!!!

void ShapeBase::advanceThreads(F32 dt) { for (U32 i = 0; i < MaxScriptThreads; i++) { Thread& st = mScriptThread; if (st.thread) { if (!mShapeInstance->getShape()->sequences[st.sequence].isCyclic() && !st.atEnd && (st.forward? mShapeInstance->getPos(st.thread) >= 1.0: mShapeInstance->getPos(st.thread) <= 0)) { st.atEnd = true; updateThread(st); if (!isGhost()) { char slot[16]; dSprintf(slot,sizeof(slot),"%d",i); [b]Con::executef(mDataBlock,3,"onEndSequence",scriptThis(),slot);[/b] } } mShapeInstance->advanceTime(dt,st.thread); } } }The bold line is calling a function on the datablock when the animation sequence has reached its end.
I had never used this piece of functionality before, but I just tried it out and it seems to work. So, to utilize this just declare a function on your datablock named, "onEndSequence" that takes three parameters. It would like something like this:
function [i]datablockName[/i]::onEndSequence(%this, %object, %slot){ .... }Hope that helps.
