From a2dec6c32a8a7907fc3faaae761c97132c11a088 Mon Sep 17 00:00:00 2001 From: matthijs Date: Mon, 31 Jan 2005 11:23:10 +0000 Subject: (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(). --- settings.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) (limited to 'settings.c') diff --git a/settings.c b/settings.c index 3d0d8f87f..f67090732 100644 --- a/settings.c +++ b/settings.c @@ -823,6 +823,33 @@ static const SettingDesc patch_player_settings[] = { {"window_snap_radius", SDT_UINT8, (void*)10, &_patches.window_snap_radius, NULL}, + /* New Path Finding */ + {"new_pathfinding_all", SDT_BOOL, (void*)false, &_patches.new_pathfinding_all, NULL}, + + /* When a red signal is encountered, a small detour can be made around + * it.
