Darkvater a3d40a29fc (svn r3008) [ 1247535 ] Native Support for Win64 (compile&run only) (michi_cc)
Fix warning in graph_gui.c with const problem
2005-10-02 22:39:56 +00:00
matthijs cd54bf48d1 (svn r2929) * Move DistanceTrack from map.c to npf.c and rename to NPFDistanceTrack.
* Make NPFDistanceTrack return the distance multiplied by NPF_TILE_LENGTH to prevent rounding
  This should make ship and train pathfinding more accurate and faster.
* Update IsEndOfLine to prevent trains from trying to go off a slope onto a tunnel entrance.

ludde 6013b327f7 (svn r2560) Fix: various minor code changes.
Added RandomTile/RandomTileSeed functions to generate a random tile.
Changed landscape routines so they don't assume that the Y map side is a power of two. (support for this is not complete, though)
Changed some frequently used map macros to not compute the values each time.
Silence some warnings on MSVC.

tron 8c1d74162f (svn r2558) Change the internal map format from 7 arrays to one array of structs, this doesn't change the saved format for now. It's a stepping stone for further changes. 2005-07-13 18:04:01 +00:00

Darkvater b438b1248c (svn r2397) - CodeChange: rename all "ttd" files to "openttd" files. 2005-06-02 19:30:21 +00:00
matthijs b02dde1982 (svn r2181) - Add: DistanceTrack() to calculate the distance over optimally laid out tracks.
- Codechange: [NPF] Removed unused heuristic function NPFCalcTileHeuristic().
- Codechange: [NPF] Use DistanceTrack() instead of DistanceManhattan() for ship and train heuristic.
- Codechange: Renamed variables x and y to dx and dy in some of the distance calculation functions.

matthijs a2dec6c32a (svn r1751) - Feature: New PathFinder (NPF).
- Supports trains, road vehicles and ships.
	- Uses A* pathfinding (same codebase as the new ai).
	- Currently unlimited search depth, so might perform badly on large maps/networks (especially ships).
	- Will always find a route if there is one.
	- Allows custom penalties for obstacles to be set in openttd.cfg (npf_ values).
	- With NPF enabled, ships can have orders that are very far apart. Be careful, this will break (ships get lost) when the old pathfinder is used again.
- Feature: Disabling 90 degree turns for trains and ships.
	- Requires NPF to be enabled.
	- Ships and trains can no longer make weird 90 degree turns on tile borders.
- Codechange: Removed table/directions.h.
	- table/directions.h contained ugly static tables but was included more than once. The tables, along with a few new ones are in npf.[ch] now. Better suggestions for a location?
- Fix: Binary heap in queue.c did not allocate enough space, resulting in a segfault.
- Codechange: Rewritten FindFirstBit2x64, added KillFirstBit2x64.
- Codechange: Introduced constant INVALID_TILE, to replace the usage of 0 as an invalid tile. Also replaces TILE_WRAPPED.
- Codechange: Moved TileAddWrap() to map.[ch] 
- Add TileIndexDiffCByDir(), TileIndexDiffCByDir(). 
- Codechange: Moved IsTrainStationTile() to station.h
- Add: IsRoadStationTile() and GetRoadStationDir().

tron 3a89108a55 (svn r1722) -Feature: Bigger maps - anyone? 2005-01-29 19:45:14 +00:00
tron 3617d24318 (svn r1706) Implement ScaleByMapSize() and ScaleByMapSize1D()
These scale a number relative to the map size/circumference.
Use them to scale the amount of map objects.
Of course at the moment they return just the input, because there are no bigger/smaller maps yet.

truelight c2ee8d70e4 (svn r1288) -Codechange: changed _map2 to an uint16. It is still saved and loaded as
an uint8 till the savegame version is bumped to version 5. Then it works 
automaticly as a fully uint16. So _stations[] can not be increased till 
after the bump!!
