Hi Guys
i've done this in the past, I do have a little class to handle it but it's
quite a mess so I won't share the whole thing.
Essentially the best thing to do is to get hold of the original animation path
then split it into the sub animation you require.
Then when you want to play a specific one you set it as the current for the
AnimationPathCallback
Here's the basic code I use to do that
Code:
void SplitAni::ReSampleSubAni(int subID, int from, int to)
{
if(subID<0 || subID>=(int)_splitAnis.size())
{return;}
//check the original path is good
if(!_originalAni)
{return;}
//clear the current path
_splitAnis[subID]->getTimeControlPointMap().clear();
//find the number of frames in the original animation
osg::AnimationPath::TimeControlPointMap timeMap =
_originalAni->getTimeControlPointMap();
//seconds per rame
//int totalFrames = (int)timeMap.size();
double secsPerFrame = (double)1.0f/_fps;
//get start end frames as times
double frameT = from*secsPerFrame;
double endT = to*secsPerFrame;
int newCount=0;
while(frameT<endT)
{
osg::AnimationPath::ControlPoint cp;
_originalAni->getInterpolatedControlPoint(frameT, cp);
//insert into the subanimation starting from time 0
_splitAnis[subID]->insert(newCount*secsPerFrame, cp);
//step to nxt time
frameT+=secsPerFrame;
//increase new frame count
newCount++;
}
}
_splitAnis is just an array of osg::AnimationPath and _fps is the frame rate of
the original animation path.
Hope that helps
Tom
