(svn r5312) - Fix (r5288): Be very strict about terraforming. If a rail tile has a foundation already, bail out.

e835bba5b1
(svn r5288) - Fix [FS#199]: Tunnel construction could erronously terraform a foundationed tile with rails. This also fixes another bug where you could implicitly remove a foundation by raising nearby sloped land. Desirable perhaps, but unwanted.

(svn r5155) - Remove the bridge branch merge (revision r5070)
18 years ago
25a63ec7af
(svn r5070) Merged the bridge branch
...
-Feature: Bridges can now be placed above:
Any railway track combination (excluding depots and waypoints)
Any road combination (excluding depots)
Clear tiles (duh), including fields
Tunnel entrances
Bridge heads
Thanks to Tron for idea and implementation, KUDr for the yapf synchronization and many others for hours of testing
There are still a number of visual problems remaining, especially when electric railways are on or under the bridge.
DO NOT REPORT THOSE BUGS FOR THE TIME BEING please.

(svn r4586) - Codechange: Recursive commands that rely on _error_message to handle success/failure can fail if a recursive call fails but doesn't set the error message, thus resulting in an old, possibly erroneous being used (see FS#130 prior to r4585). Now properly reset the global variable _error_message in these cases.

(svn r4572) Remove vehicle_leave_tile_proc
...
There's exactly one implemented function (unbarring a level crossing) and one place where it can be triggered (a train leaves a level crossing)
It's a bit overkill, so just handle this one case where it can happen

(svn r3992) -Fix: Rewrote the code to determine whether a rail-tile can be terraformed.
...
Fixes a bug where you could terraform a tunnel (fixed by r3228, but reverted that one)
Fixes a bug introduced by r3228 which allowed steep rail tiles resulting in ... unwanted effects such as display artifacts.
That means the terraform feature should not work as intended; it also uses _valid_tileh_slopes to determine valid configurations instead of hand-brewn stuff.
TODO: _terraform_err_tile and similar TileIndices should have INVALID_TILE as "unused", not 0. (0 is a valid tile).
