From 2e05a16959ff23ff504f823a9d2b8d92a9a3f873 Mon Sep 17 00:00:00 2001 From: bjarni Date: Thu, 11 May 2006 13:31:14 +0000 Subject: [PATCH] (svn r4826) -Fix: [autoreplace] fixed possible problem when autoreplacing and was number of vehicles (of a type, not total) was reached now the new vehicle gets the same number as the old one, completely removing the problem where we could run out of numbers since we don't have to find free numbers for the new vehicles, autoreplace should be somewhat faster, specially in late games NOTE: in CmdBuildRailVehicle(), bit 0 and 1 in p2 have been switched to make the meaning of bit 0 consistent with the other build commands. CmdCloneVehicle() is modified to follow this as well --- aircraft_cmd.c | 4 ++-- roadveh_cmd.c | 4 ++-- ship_cmd.c | 7 ++++--- train_cmd.c | 18 +++++++----------- vehicle.c | 5 +++-- 5 files changed, 18 insertions(+), 20 deletions(-) diff --git a/aircraft_cmd.c b/aircraft_cmd.c index 54b8815378..fd7dad834b 100644 --- a/aircraft_cmd.c +++ b/aircraft_cmd.c @@ -158,7 +158,7 @@ static int32 EstimateAircraftCost(EngineID engine_type) /** Build an aircraft. * @param tile tile of depot where aircraft is built * @param p1 aircraft type being built (engine) - * @param p2 unused + * @param p2 bit 0 when set, the unitnumber will be 0, otherwise it will be a free number */ int32 CmdBuildAircraft(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) { @@ -186,7 +186,7 @@ int32 CmdBuildAircraft(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) return_cmd_error(STR_00E1_TOO_MANY_VEHICLES_IN_GAME); } - unit_num = GetFreeUnitNumber(VEH_Aircraft); + unit_num = (HASBIT(p2, 0) == true) ? 0 : GetFreeUnitNumber(VEH_Aircraft); if (unit_num > _patches.max_aircraft) return_cmd_error(STR_00E1_TOO_MANY_VEHICLES_IN_GAME); diff --git a/roadveh_cmd.c b/roadveh_cmd.c index c9d1176f85..963f635ecb 100644 --- a/roadveh_cmd.c +++ b/roadveh_cmd.c @@ -103,7 +103,7 @@ static int32 EstimateRoadVehCost(EngineID engine_type) /** Build a road vehicle. * @param tile tile of depot where road vehicle is built * @param p1 bus/truck type being built (engine) - * @param p2 unused + * @param p2 bit 0 when set, the unitnumber will be 0, otherwise it will be a free number */ int32 CmdBuildRoadVeh(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) { @@ -129,7 +129,7 @@ int32 CmdBuildRoadVeh(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) return_cmd_error(STR_00E1_TOO_MANY_VEHICLES_IN_GAME); /* find the first free roadveh id */ - unit_num = GetFreeUnitNumber(VEH_Road); + unit_num = (HASBIT(p2, 0) == true) ? 0 : GetFreeUnitNumber(VEH_Road); if (unit_num > _patches.max_roadveh) return_cmd_error(STR_00E1_TOO_MANY_VEHICLES_IN_GAME); diff --git a/ship_cmd.c b/ship_cmd.c index 3cb66e4304..1d6e1383d6 100644 --- a/ship_cmd.c +++ b/ship_cmd.c @@ -811,7 +811,7 @@ void ShipsYearlyLoop(void) /** Build a ship. * @param tile tile of depot where ship is built * @param p1 ship type being built (engine) - * @param p2 unused + * @param p2 bit 0 when set, the unitnumber will be 0, otherwise it will be a free number */ int32 CmdBuildShip(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) { @@ -833,8 +833,9 @@ int32 CmdBuildShip(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) if (!IsTileOwner(tile, _current_player)) return CMD_ERROR; v = AllocateVehicle(); - if (v == NULL || IsOrderPoolFull() || - (unit_num = GetFreeUnitNumber(VEH_Ship)) > _patches.max_ships) + unit_num = (HASBIT(p2, 0) == true) ? 0 : GetFreeUnitNumber(VEH_Ship); + + if (v == NULL || IsOrderPoolFull() || unit_num > _patches.max_ships) return_cmd_error(STR_00E1_TOO_MANY_VEHICLES_IN_GAME); if (flags & DC_EXEC) { diff --git a/train_cmd.c b/train_cmd.c index 81cccfc04e..35f5d41afe 100644 --- a/train_cmd.c +++ b/train_cmd.c @@ -699,8 +699,8 @@ static void AddRearEngineToMultiheadedTrain(Vehicle* v, Vehicle* u, bool buildin /** Build a railroad vehicle. * @param tile tile of the depot where rail-vehicle is built * @param p1 engine type id - * @param p2 bit 0 prevents any free cars from being added to the train - * bit 1 when set, the train will get number 0, otherwise it will get a free number + * @param p2 bit 0 when set, the train will get number 0, otherwise it will get a free number + * bit 1 prevents any free cars from being added to the train */ int32 CmdBuildRailVehicle(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) { @@ -744,14 +744,10 @@ int32 CmdBuildRailVehicle(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) v = vl[0]; - if (HASBIT(p2, 1)) { - // no number is needed, so we assign 0.
