static void InitializeWindowsAndCaches ( )

static

Initialization of the windows and several kinds of caches.

This is not done directly in AfterLoadGame because these functions require that all saveload conversions have been done. As people tend to add savegame conversion stuff after the initialization of the windows and caches quite some bugs had been made. Moving this out of there is both cleaner and less bug-prone.

MayHaveBridgeAbove()

static bool MayHaveBridgeAbove ( Tile  t )

inlinestatic

Checks for the possibility that a bridge may be on this tile These are in fact all the tile types on which a bridge can be found.

Parameters

t	The tile to analyze

Returns

True if a bridge might have been present prior to savegame 194.

ReloadNewGRFData()

void ReloadNewGRFData

(

)

Reload all NewGRF files during a running game.

This is a cut-down version of AfterLoadGame(). XXX - We need to reset the vehicle position hash because with a non-empty hash AfterLoadVehicles() will loop infinitely. We need AfterLoadVehicles() to recalculate vehicle data as some NewGRF vehicle sets could have been removed or added and changed statistics

SetWaterClassDependingOnSurroundings()

void SetWaterClassDependingOnSurroundings	(	Tile	t,
		bool	include_invalid_water_class
	)

Makes a tile canal or water depending on the surroundings.

Must only be used for converting old savegames. Use WaterClass now.

This as for example docks and shipdepots do not store whether the tile used to be canal or 'normal' water.

Parameters

t	the tile to change.
include_invalid_water_class	Also consider WATER_CLASS_INVALID, i.e. industry tiles on land
