custom ground sprites used the index of the rail type as an offset. With the introduction of elrails this offset is incorrect, so instead there is now a lookup table within the RailTypeInfo struct to explicitly list the offset.
|
|
instead of a table lookup

code and proofreading, thanks to peter1138 for another lot of code and ideas.
|
|
get information about rail tiles
|
|
|
|
|
|
rail_map.h and not the other way round
|
|
also add SetSignalType() and use the functions
|
|
(electric/semaphore)
|
|
|
|
because the name suggests it does the former and current behavior broke in some places in very subtle ways (for example HASBIT(x, 0) != HASBIT(y, 1) doesn't work, returning a bool after HASBIT(x, 9) neither)

which direction a pieces of rail goes
|
|
- Don't treat non-booleans as booleans
- Reduce variable scope
- Bracing
- Use DeMorgan's law to make conditionals easier to read
- if cascade -> switch
- Replace some magic numbers by symbolic names
- Avoid assignments within other statements

in branch/pbs. This reverts revisions r3158, r3140, r3075, r2977, r2674, r2625, r2621, r2529, r2528, r2525, r2524, r2519, r2517, r2516, r2507, r2499. (in conjunction with Tron)
- The only change is that the nsignalsw.grf file is kept and that existing nightlies with PBS signals get those signals converted to combo-signals.

- Add: TracksOverlap() (from the map branch), TrackdirBitsToTrackBits(), DiagdirReachesTrackdirs(), DiagdirReachesTracks().
- Fix: Infinite loop in the pathfinder introduces in r3321.

comments, excess empty lines, minor other changes
nothing spectacular, just some stuff, which piled up
|
|
basic offset is read from the RailTypeInfo struct. This is (hopefully) the last DrawTile change on the way to electrified railways. While being at it, de-mystified the function a bit and added some asserts.

numbers, but fetch them from the central rail info array.
|
|
magic numbers, but fetch them from the central rail info array. This is a preparation step for electrified rails
|
|
a separate function to be used elsewhere. (Deja vu?)
|
|
functions that don't change their pointer parameters
- change a lot of byte player types to PlayerID
- beautify header files, same "#endif /* filename */" ending
|
|
request using the RailtypeInfo struct
|
|
replaced it by a member of RailtypeInfo
|
|
Renamed railtypes.c into railtypes.h, all other tables are in .h files. (It should be in the tables dir but I couldn't figure out how to get it there without deleting it first).
Added const and extern.
|
|
rail type specific information. Begun populating it with a bunch of sprites, more to come later. This should result in cleaner, more compact code which allows easy introduction of new railtypes.
|
|
with this file and wanted to get rid of this first
|
|
|
|
structs, this doesn't change the saved format for now. It's a stepping stone for further changes.
|

on more
than one railtype (like Diesel engines on electrified rail).
-Codechange: Use IsCompatibleRail where it should be used

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.

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)

blathijs for
pointing it out)
|
|
a tile is correct for a vehicle to enter it. Based upon glx's code.
- Fix: [ 1203769 ] [NPF] NPF tries to plan over bridges, through tunnels, over level crossings of other players. (glx)
- Codechange: Renamed TRANSPORT_MAX to TRANSPORT_END and added INVALID_TRANSPORT.
- Codechange: Moved IsLevelCrossing() from tile.h to rail.h
- Add: GetCrossingTransportType(), which returns the transport type (road, rail) of both tracks on a level crossing.
- Removed old TODO that was fulfilled already.

* Moved GetTileRailType() from npf.c to rail.[ch].
|
|
rail.h to rail.c
* Codechange: Move declaration of lookup arrays into the functions that need them. This doesn't pollute the global namespace with the array names.
* Add: rail.h to the openttd.vcproj and openttd.dsp for MSVC.
|
|
the linker will complain if they are not defined (ie when rail.c is not included).
|
|
calls to the associated wrapper functions.
* Codechange: Made npf.c use some map array accessing wrappers instead of direct access.
* Codechange/Fix: Named every enum in tile.h. Fixes a nasty bug on MSVC where arrays would be initialised with zeroes (tnx Asterix_)
* Removed magic numbers from tables in tile.c.
* Added some explicit casts in tile.h.
|
|
* 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.
