Sometimes you want to manually control bones in a skeletally animated character, e.g. to turn the characters head toward a target. Here's one technique:

Copy to clipboard
Entity *ent = mSceneMgr->createEntity("robot", "robot.mesh");
 
 SkeletonInstance* skel = ent->getSkeleton();
 Animation* anim = skel->getAnimation("Walk");       
 Bone* manuallyControlledBone = skel->getBone("Joint10");
 manuallyControlledBone->setManuallyControlled(true);
 anim->destroyTrack(manuallyControlledBone->getHandle());


Manipulating manually controlled Bones:

Copy to clipboard
mAnimState->addTime(evt.timeSinceLastFrame);
manuallyControlledBone->yaw(Degree(evt.timeSinceLastFrame*100));


The original discussion of this feature can be seen http://www.ogre3d.org/phpBB2/viewtopic.php?t=1550 here in this forum thread.

Note: Since Ogre v1.6 you have the option of not actually destroying a track, but instead using Skeletal Blend Masks. This was discussed in the forum http://www.ogre3d.org/phpBB2/viewtopic.php?t=39510 here.
