Functions | |
| static byte | SignalAlongTrackdir (Trackdir trackdir) |
| Maps a trackdir to the bit that stores its status in the map arrays, in the direction along with the trackdir. | |
| static byte | SignalAgainstTrackdir (Trackdir trackdir) |
| Maps a trackdir to the bit that stores its status in the map arrays, in the direction against the trackdir. | |
| static byte | SignalOnTrack (Track track) |
| Maps a Track to the bits that store the status of the two signals that can be present on the given track. | |
| SigSegState | UpdateSignalsOnSegment (TileIndex tile, DiagDirection side, Owner owner) |
| Update signals, starting at one side of a tile Will check tile next to this at opposite side too. | |
| void | SetSignalsOnBothDir (TileIndex tile, Track track, Owner owner) |
| Update signals at segments that are at both ends of given (existent or non-existent) track. | |
| void | AddTrackToSignalBuffer (TileIndex tile, Track track, Owner owner) |
| Add track to signal update buffer. | |
| void | AddSideToSignalBuffer (TileIndex tile, DiagDirection side, Owner owner) |
| Add side of tile to signal update buffer. | |
| void | UpdateSignalsInBuffer () |
| Update signals in buffer Called from 'outside'. | |
