Milkshape death animation problems

by Kurtis Seebaldt · in Torque Game Engine · 02/26/2003 (10:10 pm) · 4 replies

I'm having trouble getting death animations working from Milkshape. I make an animation and add a material:

seq: death1=1-1, fps=10

It plays fine through the show tool, but in game it causes Torque to crash. I traced through with the debugger and found that it calls TSThread::getGround(F32 t, MatrixF * pMat). It dies on line 137:

q2 = &mShapeInstance->mShape->groundRotations[sequence->firstGroundFrame + frame].getQuatF(&rot2);

mShape->groundRotations[whatever] is NULL.

I'm still having trouble with this.

I can work around it by changing:

// similar to above, ground keyframe number 'frame+1' is actually offset by 'frame'
p2 = &mShapeInstance->mShape->groundTranslations[sequence->firstGroundFrame + frame];
q2 = &mShapeInstance->mShape->groundRotations[sequence->firstGroundFrame + frame].getQuatF(&rot2);

to:

if(sequence->firstGroundFrame + frame < sequence->numGroundFrames) {
// similar to above, ground keyframe number 'frame+1' is actually offset by 'frame'
p2 = &mShapeInstance->mShape->groundTranslations[sequence->firstGroundFrame + frame];
q2 = &mShapeInstance->mShape->groundRotations[sequence->firstGroundFrame + frame].getQuatF(&rot2);
} else {
p2 = &unitTranslation;
q2 = &unitRotation;
}

I don't know if the bug is in tsThread or in the Milkshape exporter. Any ideas??

Here's something I picked up from the Milkshape exporter readme...

name=start-end This declares the name of the sequence followed by
the starting and ending key frames. This option must
exist for the sequence declaration to be valid.

I don't think it will work with just one keyframe... you need to have a sequence of keyframes. How did you get an animation sequence in just one keyframe anyway? Make sure you have the right number for the end there...

One keyframe animations work just fine for root and running. I specified the material like this:

seq: death1=1-1, fps=10

Start frame is one, end frame is one. I traced through the code and it has something to do with ground transformations being saved. I posted above my workaround, but I was hoping someone could tell me if it was the exporter that was bugged or tsThread.

For some reason in DTS files exported by MilkShape with versions > 23 no ground transforms are detected. This appears unimportant for animations sequences other than the death sequences which require the ground transforms. I employed a similar work around, but the result is that the death animation does not work consistently, the player soetimes ends up in a position normal to the ground surface. Will post a solution if I figure it out. Hope someone else finds it first.
