From 486e207ea01095fb298935c66c09ff88e8d7977a Mon Sep 17 00:00:00 2001 From: celestar Date: Fri, 19 May 2006 12:08:01 +0000 Subject: (svn r4911) -Fix (FS#156): The Ai no longer attempts to build signals under bridges. NOTE 1: Remove/revert this for the bridge branch NOTE 2: Bug displays fundamental flaw in command system: If two commands, where command 2 depends on command 1, have to be checked, all those checks need to be manual. (like in this example, first build rail then build signal. BuildSignal cannot be checked without DC_EXEC as the rail isn't there yet) --- ai/default/default.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'ai/default') diff --git a/ai/default/default.c b/ai/default/default.c index c0d19adee..b0915f10a 100644 --- a/ai/default/default.c +++ b/ai/default/default.c @@ -1587,8 +1587,9 @@ clear_town_stuff:; /* signals too? */ if (j & 3) { - // Can't build signals on a road. - if (IsTileType(c, MP_STREET)) return CMD_ERROR; + /* XXX - we need to check manually whether we can build a signal if DC_EXEC is + not set because the rail has not actually been built */ + if (!IsTileType(c, MP_RAILWAY)) return CMD_ERROR; if (flag & DC_EXEC) { j = 4 - j; -- cgit v1.2.3-70-g09d2
