Member Function Documentation

getCurrentPathIndex()

int U4DEngine::U4DFollowPath::getCurrentPathIndex ( )

virtual

gets the current path the pursuer is following

Returns

index in the path(segment) vector

Reimplemented from U4DEngine::U4DSteering.

getSteering()

U4DVector3n U4DEngine::U4DFollowPath::getSteering ( U4DDynamicAction *  uAction, std::vector< U4DSegment > &  uPathContainer  )

virtual
