Last change on this file since 3789 was 3608, checked in by patrick, 20 years ago

orxonox/trunk: now there is a real speedup in compiling time when dependencies are modified: just realy only includes, what is needed. Byside the speedup, there is more overview! never add an orxonox class to stdincl.h if it doesn't have to be

90/**
91
92   <b>The TrackManager works as followed:</b> \n
93     \n
94   <b>1. Initialize it, by setting up the Graph. You can do this by using the following Commands.</b>
95    \li workOn(): changes the ID that will be altered through the changes.
[3332]96    \li setCurveType(): 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).
[3333]97    \li setDuration(): sets the length of the current path in seconds.
[3330]98    \li addPoint(): adds a point to the Curve.
99    \li addHotPoint(): adds save/splitpoint.\n
100    \li fork(): adds some interessting non-linear movments through the level (fork will force addHotPoint if not done then).
101    \li condition(): decides under what condition a certain Path will be chosen.
102    \li join(): joins some tracks together again. Join will set the localTime to the longest time a Path has to get to this Point)
103    \li setSavePoint(): Sets a HotPoint into a savePoint. A Savepoint can be used as a rollbackpoint if a Player gets shot.
104
[3332]105    HotPoints and Joins are at the beginning of a TrackElement. \n
106    SavePoints and Forks are at the end of a TrackElement \n
[3330]107    look out: <b>SAVEPOINTS CAN NOT BE FORKS</b> (but joins), because the condition is really hard to guess if you do not give some impuls. \n
108\n
109   <b> 2. Runtime knows the following: </b>
110    \li calcPos(): returns the current position on the track
111    \li calcDir(): returns the current Direction the track is flying on.
112    \li tick(): makes a Step on the Path. increases localTime by dt.
113    \li choosePath(): a Function that decides which Path we should follow.
114   
115   TrackManager can be handled as a StateMachine.
[3331]116   \n\n
117    Names:
118    \li TrackManager: handles Tracks
119    \li Track:        The Track that the ship can follow
120    \li Path:         one way through the Level, that is dependent on conditionals.
121    \li Conditional:  A decition making device, that chooses betwen different TrackElements for the Path.
122    \li TrackElement: A Part of A whole Track
