天龙八部Online 骨骼动画文件加载

天龙对skeleton文件做了一点小的改动, 要正确加载需要更改加载skeleton的代码.
对OgreSkeletonSerializer.cpp文件里面的SkeletonSerializer::readAnimationTrack函数进行修改.

  void    SkeletonSerializer::readAnimationTrack(DataStreamPtr   &    stream, Animation   *    anim, 
        Skeleton  *   pSkel)
     {
         //  unsigned short boneIndex     : Index of bone to apply to
        unsigned  short  boneHandle;
        readShorts(stream,  & boneHandle,  1 );

         //  Find bone
        Bone  * targetBone  =  pSkel -> getBone(boneHandle);

         //  Create track
        NodeAnimationTrack *  pTrack  =  anim -> createNodeTrack(boneHandle, targetBone);

         //  Keep looking for nested keyframes
         if  ( ! stream -> eof())
        {
            unsigned  short  streamID  =  readChunk(stream);

             // while(streamID == SKELETON_ANIMATION_TRACK_KEYFRAME && !stream->eof())
             while ((streamID  ==  SKELETON_ANIMATION_TRACK_KEYFRAME  ||  streamID  ==   0x4120 )  &&   ! stream -> eof())
            {
                 if  (streamID  ==   0x4120 )
                {
                    unsigned  short  len;
                    readShorts(stream,  & len,  1 );
                    unsigned  short  flags;
                    readShorts(stream,  & flags,  1 );

                     int  count  =  (mCurrentstreamLen  -   4   -   4 )  /   4 ;
                     if  (len  !=  count  /   8 )
                        len  =  len;
                     float  time;
                     for  ( int  i  =   0 ; i  <  len; i  +=   1 )
                    {
                        readFloats(stream,  & time,  1 );
                        TransformKeyFrame  * kf  =  pTrack -> createNodeKeyFrame(time);

                        Quaternion rot  =  Quaternion::IDENTITY;
                         if  (flags  &   1 )
                        {
                            readObject(stream, rot);
                        }
                        kf -> setRotation(rot);

                        Vector3 trans  =  Vector3::ZERO;
                         if  (flags  &   2 )
                        {
                            readObject(stream, trans);
                        }
                        kf -> setTranslate(trans);
                    }
                }
                 else
                    readKeyFrame(stream, pTrack, pSkel);

                 if  ( ! stream -> eof())
                {
                     //  Get next stream
                    streamID  =  readChunk(stream);
                }
            }
             if  ( ! stream -> eof())
            {
                 //  Backpedal back to start of this stream if we've found a non-keyframe
                stream -> skip( - STREAM_OVERHEAD_SIZE);
            }

        }
