2005-01-31(svn r1751) - Feature: New PathFinder (NPF).matthijs
- 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().
2005-01-31(svn r1749) Move the functions which calculate distances to map.[ch] and ↵tron
give the more meaningful names
2005-01-29(svn r1722) -Feature: Bigger maps - anyone?tron
2005-01-29(svn r1714) Add missing includetron
2005-01-29(svn r1713) Split off several functions which query/set information about a ↵tron
single tile from map.h and put them into a seperate file tile.h
2005-01-28(svn r1706) Implement ScaleByMapSize() and ScaleByMapSize1D()tron
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.
2005-01-25(svn r1676) Increase the size of TileIndex and TileIndexDiff to 32bits and ↵tron
adapt the save/load data and some other parts of the code to that change WARNING: If i made any mistake here it WILL lead to corrupted savegames!
2005-01-18(svn r1560) Introduce SetTileType() and SetTileHeight()tron
Replace direct references to _map_type_and_height with these
2005-01-16(svn r1545) Add TileHeight() which returns the height (not multiplied by 8)tron
Replace some direct references to _map_type_and_height with TileHeight()/IsTileType()
2005-01-16(svn r1542) Rename TileHeight to TilePixelHeight, because this is what it ↵tron
actually returns
2005-01-16(svn r1536) Move GET_TILEHEIGHT, GET_TILETYPE and IS_TILETYPE to map.h, turn ↵tron
them into inline functions and add some asserts
2005-01-10(svn r1475) Fix some more signed/unsigned comparison warningstron
2005-01-09(svn r1447) Move TILE_ADD(), TILE_ADDXY() and SafeTileAdd() to map.[ch] and ↵tron
make the latter map size agnostic
2005-01-07(svn r1415) Move TILE_FROM_XY and TILE_XY to map.h and push TILE_[XY] bits ↵tron
from map.h into map.c. Now the whole source except map.c is independent of TILE_[XY]_BITS!
2005-01-07(svn r1414) Move TileIndex, TILE_MASK and GET_TILE_[XY] to map.h and turn ↵tron
the latter into inline functions names Tile[XY]
2005-01-06(svn r1396) Introduce TileIndexDiffC - the compile time version of TileIndexDifftron
2005-01-05(svn r1386) Move TileIndexDiff to map.htron
Move _tileoffs_by_dir to map.[ch] and encapsulate it in TileOffsByDir()
2005-01-03(svn r1344) Use MapSize[XY]() (or MapSize()/MapMax[XY]() where appropriate) ↵tron
instead of TILES_[XY]
2005-01-03(svn r1337) Use MapMax[XY]() (or MapSize[XY]() if appropriate) instead of ↵tron
TILE_MAX_[XY] While here replace one erroneous TILE_MAX_X with MapMaxY()
2004-12-28(svn r1288) -Codechange: changed _map2 to an uint16. It is still saved and ↵truelight
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!!
2004-12-17(svn r1144) Don't rely on sizeof() to determine the map size, use MapSize() ↵tron
instead
2004-12-16(svn r1130) Add helper functions to query map sizetron
2004-12-15(svn r1117) Move map arrays and some related macros into their own files ↵tron
map.c and map.h
