2005-07-10(svn r2541) -Feature: Modified IsCompatibleRail so that an engine can move ↵celestar
on more than one railtype (like Diesel engines on electrified rail). -Codechange: Use IsCompatibleRail where it should be used
2005-07-04(svn r2516) - Feature: [pbs] Implement path-based-signalling. This allows ↵hackykid
multiple trains within the same signal block, provided their paths dont intersect. For this the block must have all exit and entry signals be pbs signals. Place these by ctrl-clicking 4 times on a normal signal. - Feature: [pbs] Implement autoplacement of pbs blocks, when a block has an entry and an exit pbs signal, covert the entire block to pbs. Can be turned off in the patch settings. - Feature: [pbs] Allow showing of reserved status by making the tracks darker, when the pbs debug level is at least 1.
2005-07-03(svn r2514) - Codechange: [NPF] Move the checking of railtype into a ↵matthijs
funciton IsCompatibleRail(). - Codechange: [NPF] Check the railtype along a route against the engine type instead of against the previouse tile. This clears the way for electriefied rails. - Add: [NPF] [ 1209644 ] A penalty for crossings (peter1138)
2005-07-01(svn r2504) Move Draw*EngineInfo to engine_gui.c to reduce dependenciestron
2005-06-27(svn r2492) Remove some pointless casts and fix some nearby indentationtron
2005-06-25(svn r2486) Turn TILE_FROM_XY into an inline function and rename it to ↵tron
TileVirtXY
2005-06-24(svn r2483) Replace almost 500 "uint tile" (and variants) with "TileIndex tile"tron
2005-06-23(svn r2475) -Fix: [ 1214982 & 1217473 ] realistic acceleration problem. (glx)celestar
2005-06-21(svn r2467) - Fix: [newgrf] Prevent trains with shorter wagons breaking ↵hackykid
apart when reversing in some cases. (Therax)
2005-06-16(svn r2448) General cleanup of rail related code, more to follow.matthijs
* Add: rail.[ch] for rail-related enums and wrapper functions. * Codechange: Removed dozens of magic numbers with below enums. * Codechange: Rewrote CheckTrackCombination(). * Add: TILE_SIZE, TILE_PIXELS and TILE_HEIGHT constants. * Add: enums RailTileType, RailTileSubtype, SignalType to mask against the map arrays. * Add: enums Track, TrackBits, Trackdir, TrackdirBits for railway track data. (Note that the old RAIL_BIT constants are replaced by TRACK_BIT ones). * Add: enums Direction and DiagDirection * Codechange: Moved a bunch of track(dir) related lookup arrays from npf.[ch] to rail.[ch]. * Codechange: move RailType enum from tile.h to rail.h. * Add: Wrapper functions for masking signal status in the map arrays: SignalAlongTrackdir, SignalAgainstTrackdir and SignalOnTrack. * Add: Wrapper functions to access rail tiles, using above enums * Add: Wrapper functions to modify tracks, trackdirs, directions, etc. * Add: Wrapper functions for all lookup arrays in rail.[ch] (Arrays are still used in parts of the code) * Codechange: Renamed some variables and arguments to better represent what they contain (railbit -> track, bits -> trackdirbits, etc.). * Codechange: Don't use FindLandscapeHeight() in CmdRemoveSingleRail(), since it returns way too much info. Use GetTileSlope() instead. * Codechange: [NPF] Removed some unused globals and code from npf.c.
2005-06-15(svn r2441) -Feature: You can now give transfer order to set up feeder systemscelestar
2005-06-15(svn r2440) - Fix: [newgrf] Fix the spritesorter to handle overlapping ↵hackykid
sprites properly, this fixes display problems with really short wagons. (algorithm by patchman, ported by therax) - Fix: [newgrf] Too short wagons could break the 'follow next vehicle' code used in the traincontroller. Clamp better to prevent this.
2005-06-07(svn r2433) - CodeChange: unmagicify all road/train crossings with ↵Darkvater
IsLevelCrossing() function (peter1138)
2005-06-07(svn r2432) Use GetEngine() instead of DEREF_ENGINE() or even _engines[]tron
2005-06-07(svn r2431) - Fix: [newgrf] clamp() instead of assert() on the result of ↵hackykid
the vehicle length calculation, as it can depend on external input. (thanks tron)
2005-06-06(svn r2428) - Feature: [newgrf] Implement shorter train vehicles (Therax), ↵hackykid
and the callback that goes with it. - Codechange: Remove some magic numbers (PALETTE_CRASH)
2005-06-06(svn r2427) - Fix: CmdMoveRailVehice; Prevent possible assertion failure ↵hackykid
when moving vehicles within one chain.
2005-06-06(svn r2423) - CodeChange: Include first_engine in the train cache, instead ↵hackykid
of calculating it all over the place. - Fix: Also recalculate the train cache values for 'wagon chains' (in the depot without an engine), to avoid possible desyncs later. - Fix: Make CmdMoveRailVehicle update the caches of the correct trains in all cases.
2005-06-06(svn r2415) - Fix: [newgrf] Powered Wagons - Don't assume an undefined ↵hackykid
callback will fail.
2005-06-06(svn r2414) - Feature: [newgrf] Implement powered wagons, and the callback ↵hackykid
that goes with it.
2005-06-05(svn r2411) - Codechange: Have trains cache stuff like consist ↵hackykid
power/weight/max speed instead of recalculating it each time. - Fix: Station ratings now depends on the max speed of a consist, without being affected by other speed limits from realistic acceleration.
2005-06-04(svn r2407) Use {Get,Is}TileOwner to get/check the owner of a tile and fix ↵tron
some bogus reads of _map_owner
2005-06-03(svn r2401) - Fix: [newgrf] Finish up callback mechanism, implement 'refit ↵hackykid
capacity' callback slightly more correct.
2005-06-02(svn r2397) - CodeChange: rename all "ttd" files to "openttd" files.Darkvater
2005-06-01(svn r2389) - Feature: [newgrf] Implement the mechanism for handling newgrf ↵hackykid
callbacks. - Feature: [newgrf] Implement the 'refit capacity' callback.
2005-06-01(svn r2388) - Fix: [realistic accel] Very slow trains no longer get an ↵hackykid
increase in maximum speed when part of them is in a depot.
2005-05-26(svn r2365) - Change: [refitting] Make refitting capacities for trains ↵hackykid
newgrf compatible. Train vehicles can now carry twice as much mail/goods as other cargo, and four times as much passengers. - Fix: [refitting] The refit window now shows the correct refit options for the entire consist. Only if at least one of the vehicles in the train can be refitted to a certain cargo, it is shown in the list. - Fix: [refitting] When refitting to a cargo which is already carried by some vehicles in the consist, the capacities of those vehicles are taken into account when calculating the new capacity of the train in the refit window.
2005-05-17(svn r2347) - Fix (regression): depot window did not get redrawn when a ↵Darkvater
non-train-engine was sold.
2005-05-14(svn r2306) - CodeChange: Check the last commands; refits. This needed an ↵Darkvater
extensive rewrite and global/local-cargo ID juggling and bitmasking. However with this done it looks better as well and is compatible with newgrf handling. Big thanks to HackyKid for doing most of the work. This also closes patch "[ 1199277 ] Command checks"
2005-05-12(svn r2298) - CodeChange: removed CmdAbuses: CmdSetTownNameType(), ↵Darkvater
CmdStartNewGame(), CmdCreateScenario(), CmdSetNewLandscapeType() and CmdGenRandomNewGame(). - CodeChange: renamed CmdTrainGotoDepot() to CmdSendTrainToDepot() to be consistent with other depot commands. - CodeChange: 'newgame' console command now calls the unabused GenRandomNewGame(). For the server it still creates a new game, a client quits the game and continues in SP. - CodeChange: in the game-difficulty window, setup the disabled buttons on window creation, not every redraw.
2005-05-11(svn r2294) - CodeChange: check the service interval settings when changing ↵Darkvater
of all vehicle-types. To simplify things introduce GetServiceIntervalClamped() that returns the same or clamped value of the new service interval. There were some inconsistencies in the gui files so I had to change those, and const correctness kicked in, so it's a bit messy at certain points.
2005-05-11(svn r2290) - CodeChange: protect the next batch of commands. This brings us ↵Darkvater
to a total of 61, which is 53% :) - CodeChange: To correctly accept engine-prototypes, the best-player checking has been moved to its own function, I hope it functions the same as before. - CodeChange: Added symbolic types of PlayerID, OrderID and EngineID. For engines also added GetEngine() and IsEngineIndex(), similar to the other such functions. - CodeChange: To correctly build industries, some tables have been moved to build_industry.h. The only way to find out currently if an industry is valid in a climate is by looping all industries and checking if it matches. Also to comply with the patch setting build_rawmaterial_industries, it is assumed that these industries do not accept any cargo of any type. This can and probably should changed in the future to some flag in their struct. Also use _opt_ptr instead of _opt. - CodeChange: implemented the HQ checking code inspired by MarkR2 in "[ 1190944 ] Many commands not checked for security". Unfortunately it is impossible to prevent only deleting a HQ by a modified client atm. - CodeChange: For insert order and modify order their parameters are implicitely truncated to 8 bits, instead of the 16 bits said in the comments.
2005-05-09(svn r2288) - CodeChange: protected the next batch of commands (41 so far, ↵Darkvater
out of 115). - CodeChange: changed the airport gui airport-type checking. Added function GetValidAirports() that returns bitmasked availibility, is also used for checking. - CodeChange: to check tree-planting, 2 const arrays have been moved to table/tree_land.h (type and count) - CodeChange: added IsTownIndex() in following of IsStationIndex(), etc. - Fix (regression): road tunnels did not work anymore, forgot that their type was 0x200 (documented now)
2005-05-08(svn r2283) - Fix (regression): [ 1197493 ] train_gui.c:1341: failed ↵Darkvater
assertion ..., somehow RebuildVehicleList() got lost during the rewrite :P
2005-05-07(svn r2281) - Fix: [ 1115204 ] [NPF] When pressing the goto depot button, ↵matthijs
trains will now also look behind it if there is no depot in front. If so, the train reverses immediately. This also work anywhere, not just at stations. - Add: [NPF] Reversing inside of depots now has a penalty. It also applies to trains only, other vehicles shouldn't bother reversing. - Fix: [NPF] When checking whether to reverse a train, the trackdir of the first loc was used instead of the last vehicle as a starting node for pathfindig. This might have caused some trains not reversing when they should have (or vice versa). Typo introduced when converting to GetVehicleTrackdir() in r2256. - CodeChange: [NPF] Removed duplicate code by letting NPFRouteTjoStationOrTile() call NPFRouteToStationOrTileTwoWay(). - Add: [NPF] NPFRouteToDepotBreadthFirstTwoWay() to find a depot while also looking backwards. - Add: It is now possibly to specify a path cost for aystar starting nodes.
2005-05-06(svn r2274) - Codechange: some comments, parentheses and EngineID typedef ↵Darkvater
for engine_type
2005-05-05(svn r2270) - Fix/Codechange: fix up selling rail vehicles. Try to be smart ↵Darkvater
about it. When selling dual-headed trains, also sell the rear end; if the now-first wagon is an engine, make it a train. When selling the whole train, try to leave dual-headed setups intact
2005-05-03(svn r2262) - Fix: Assertion when vehicle in a depot wants to do pathfinding.matthijs
GetVehicleTrackdir now tries to get a valid trackdir as much as possibly, by assuming that a vehicle is facing outwards in a depot or road station, for example. - Codechange: [Multistop] Multistop now also tries to find a slot for road vehicles that are in stations, since the pathfinder now properly handles that.
2005-05-03(svn r2261) - Fix: When crashed vehicles try to find a depot for servicing, ↵matthijs
openttd asserts. Crashed vehicles shouldn't find depots anyway...
2005-05-02(svn r2256) - Fix: Trains cannot find a depot when they are in a tunnel. (glx)matthijs
- Add: GetVehicleTrackdir() helper function. - Codechange: Moved SortStruct from vehicle_gui.h to ttd.h, so the dependency from vehicle.h on vehicle_gui.h could be removed. - Codechange: Typedeffed the VehicleTypes struct so it can be used as the type for Vehicle.type instead of "byte". - Codechange: Removed prototype for VehicleSorter(), which had no implementation anymore and was never called.
2005-04-15(svn r2202) - Fix: [NPF] When a vehicle could not reach its target, it would ↵matthijs
choose a random direction. It will now try to get as close as possible.
2005-04-12(svn r2189) Introduce and use IsCompatibleTrainStationTile()tron
This should prevent trains, which are longer than the station, to turn around without stopping under certain circumstances and fix speed limit for trains entering a station, when realistic accerlation is used
2005-04-12(svn r2188) Revert r2185, because trains always accerlated (Requested by ↵tron
Celestar)
2005-04-12(svn r2187) Implement a slightly better workaround than r1588 did. (Joint ↵tron
effort with Celestar)
2005-04-11(svn r2185) -Fix: Made sure that the realistic acceleration does not freeze ↵celestar
trains anymore
2005-04-11(svn r2180) -Fix: Deceleration code now only takes into account rail station ↵celestar
tiles for computing the remaining distance
2005-04-11(svn r2179) - Fix: [ 1121437, 1114228 ] Vehicles not entering depots for ↵matthijs
auto servicing.
2005-04-02(svn r2119) - Fix: [ 1172878 ] Trains "Go to depot" button: click twice skip ↵pasky
to next order (patch by Loic GUILLOUX). I also added short explanation of OF_/OFB_ difference to order.h.
2005-03-29(svn r2105) -Codechange: Added a cache for the first vehicle of a chain to ↵celestar
increase performance, especially with many long trains
2005-03-25(svn r2058) -Fix: hopefully this fixes the reverse-train-in-depot-bugs (plural)truelight
