Member Function Documentation

void WorldEntity::createPresentPoint (  int  time_stamp  )  [virtual]

Creates from current available data new mPresentPoint. Parameters: time_stamp  Defines the timestamp of the point being created Reimplemented in Tank. Definition at line 26 of file worldentity.cpp. References CommonEntity::mID, HistoryPoint::mID, CommonEntity::mOrientation, HistoryPoint::mOrientation, CommonEntity::mPosition, HistoryPoint::mPosition, mPresentPoint, mSpeed, HistoryPoint::mSpeed, and HistoryPoint::mTimeStamp.

void WorldEntity::shiftHistory (   )

Shifts interpolation history by one step. Definition at line 15 of file worldentity.cpp. References HISTORY_LENGTH, mHistoryPoints, and mPresentPoint. Referenced by updateHistory().

void WorldEntity::updateHistory (  HistoryPoint *  new_point  )

Adds new point to the history and present point. Changes the present history point to the new point and then shifts the history. WARNING! It doesn't delete the present point. This is behaviour that is expected as long as mPresentPoint and mHistoryPoints[0] points to the same objects (this is correct). Parameters: new_point  Point that should be added as the beginning of history :P Definition at line 38 of file worldentity.cpp. References mPresentPoint, and shiftHistory().
