Detailed Description

The TrackManager handles the flow of the Players through the game.

Todo:

write the methodes

The TrackManager works as followed:

1. Initialize it, by setting up the Graph. You can do this by using the following Commands.

• workOn(): changes the ID that will be altered through the changes.
• setType: lets you set the CurveType of the Curve we are Working on. (default is BezierCurve, set this as early as possible, for this uses resources).
• setLength(): sets the length of the current path in seconds.
• addPoint(): adds a point to the Curve.
• addHotPoint(): adds save/splitpoint.
  
• fork(): adds some interessting non-linear movments through the level (fork will force addHotPoint if not done then).
• condition(): decides under what condition a certain Path will be chosen.
• join(): joins some tracks together again. Join will set the localTime to the longest time a Path has to get to this Point)
• setSavePoint(): Sets a HotPoint into a savePoint. A Savepoint can be used as a rollbackpoint if a Player gets shot.

look out: SAVEPOINTS CAN NOT BE FORKS (but joins), because the condition is really hard to guess if you do not give some impuls.

2. Runtime knows the following:

• calcPos(): returns the current position on the track
• calcDir(): returns the current Direction the track is flying on.
• tick(): makes a Step on the Path. increases localTime by dt.
• choosePath(): a Function that decides which Path we should follow.

TrackManager can be handled as a StateMachine.

Member Function Documentation

void TrackManager::addHotPoint (  Vector  newPoint  )

adds save/splitpoint. Parameters: newPoint  The point to add.

void TrackManager::addPoint (  Vector  newPoint  )

adds a point to the current TrackElement Parameters: newPoint  The point to add.

Vector TrackManager::calcDir (   )

calculates the Rotation for the localTime of the Track. Returns: the calculated Rotation

Vector TrackManager::calcPos (   )

calculates the Position for the localTime of the Track. Returns: the calculated Position

void TrackManager::choosePath (  int  graphID  )

a Function that decides which Path we should follow. Parameters: graphID  The Path to choose.

void TrackManager::condition (  int  groupID, PathCondition  cond )

decides under what condition a certain Path will be chosen. Todo: really do this!!

TrackElement TrackManager::findTrackElementByID (  int  trackID  )  [private]

Searches for a given trackID. Parameters: trackID  the trackID to search for. Returns: The TrackElement #trackID if found, NULL otherways.

void TrackManager::fork (  int  count,   ... )

adds some interessting non-linear movments through the level. Parameters: count  The Count of childrens the current HotPoint will have. If no HotPoint was defined the last added Point will be rendered into a fork. If the HotPoint was defined as a savePoint the Point will not be set into a fork.

void TrackManager::forkV (  int  count, int *  trackIDs )

adds some interessting non-linear movments through the level. Parameters: count  The Count of childrens the current HotPoint will have. trackIDs  A Pointer to an Array of ints which will hold the trackID's (the user will have to reserve space for this). See also: void TrackManager::fork(int count, ...)

void TrackManager::join (  int  count,   ... )

joins some tracks together again. Parameters: count  The count of Paths to join. Join will set the localTime to the longest time a Path has to get to this Point. Join will join all curves to the first curve.

void TrackManager::joinV (  int  count, int *  trackIDs )

joins some tracks together again. Parameters: count  The count of Paths to join. trackIDs  an Array with the trackID's to join See also: void TrackManager::join(int count, ...)

void TrackManager::setLength (  float  time  )

Sets the length of the current path in seconds. Parameters: time  The length in seconds.

void TrackManager::setSavePoint (  void   )

Sets the last HotPoint into a savePoint. If no HotPoint was defined the last added Point will be rendered into a savePoint. If the HotPoint was defined as a fork the Point will not be set into a savePoint.

void TrackManager::tick (  float  dt  )

Advances the local-time of the Track around dt. Parameters: dt  The time about which to advance.

void TrackManager::workOn (  int  trackID  )

Sets the trackID we are working on. Parameters: trackID  the trackID we are working on
