triangle3df triOut;
vector3df finalPos;
bool bFalling;
ISceneNode* sd ;

collisionManager->getCollisionResultPosition(
mainCastleSelector ,
this->mHero->getPosition(),
vector3df(100.0,100.,100.),
vector3df(0.,0.,0.),
triOut,
finalPos,
bFalling,
*sd, <--------------problem
0.0005,
vector3df(0.0,-0.001,0.0));

what is it?And how should I supply 8th parameter of above that I marked?

Just remove the star ('*') in front of the element. It will return the scene node if a collision happened with it.
