Look at the svn log via: cd OpenSceneGraph/src/osg svn log Sequence.cpp I last change to Seequence.cpp was: r7765 | robert | 2008-01-04 15:33:21 +0000 (Fri, 04 Jan 2008) | 2 lines >From Glenn Waldron, "I found that osg::Sequence::setDuration(speed,reps) was not changing the animation speed factor as expected. The one-line fix (line 312) is attached" Which is before the 2.4 release, so it looks like the problem is likely to still exist. > To reproduce the bug: > > Create a template osg::Sequence node (and underlying geometry) but do not > attach the node to the current active scenegraph. > At some point during the rendering loop (perhaps on a keystroke) clone the > sequence node (I use the call: > > dynamic_cast<osg::Node*>(templateNode -> clone( osg::CopyOp( > (osg::CopyOp::CopyFlags)osg::CopyOp::DEEP_COPY_NODES ) ) ) > > Set the cloned sequence node duration to a value that makes the animation > run slower (i.e. 2.0). > Start the cloned sequence (using setMode()). > Repeat steps 2 – 4 and observe that the cloned sequences do not run slow but > run as fast, appearing to ignore the duration that has been set on them. > > > > Looking at the 'good documentation' (2.4 source code), I see that _start is > being set to _now (osg::Sequence::setMode(), line 192).
