Detailed Description

Chunks and fix-ups for TTO/TTD/TTDP savegames.

TTO loader code is based on SVXConverter by Roman Vetter.

Definition in file oldloader_sl.cpp.

Function Documentation

◆ FixOldVehicles()

void FixOldVehicles ( )

Convert the old style vehicles into something that resembles the old new style savegames.

Then AfterLoadGame can handle the rest of the conversion.

Definition at line 163 of file oldloader_sl.cpp.

◆ FixTTDDepots()

static void FixTTDDepots ( )

static

Workaround for SVXConverter bug, depots 252-255 could be invalid

Definition at line 102 of file oldloader_sl.cpp.

References GetDepotIndex(), IsDepotTile(), and Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero >::PoolItem<&_depot_pool >::Iterate().

◆ FixTTOEngines()

static bool FixTTOEngines ( )

static

TTD->TTO remapping of engines; 255 means there is no equivalent. SVXConverter uses (almost) the same table.

TTO->TTD remapping of engines. SVXConverter uses the same table.

Definition at line 343 of file oldloader_sl.cpp.

References Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero >::PoolItem<&_vehicle_pool >::Iterate(), and lengthof.

◆ LoadOldVehicle()

bool LoadOldVehicle	(	LoadgameState *	ls,
		int	num
	)

Load the vehicles of an old style savegame.

So we can set the proper next pointer while loading.

Parameters

ls	State (buffer) of the currently loaded game.
num	The number of vehicles to load.

Returns: True iff loading went without problems.

Definition at line 1249 of file oldloader_sl.cpp.

◆ RemapTTOColour()

static Colours RemapTTOColour ( Colours tto )

inlinestatic

Lossy remapping of TTO colours to TTD colours. SVXConverter uses the same conversion.

Definition at line 458 of file oldloader_sl.cpp.
