From 4ae02ddbad08cb4720e8a32be7f11129d6129b7c Mon Sep 17 00:00:00 2001 From: Darkvater Date: Thu, 7 Jul 2005 22:14:37 +0000 Subject: (svn r2528) - Fix: TTDPatch games had garbage in _map3[hi]&0xF0 which interfered with OpenTTD PBS functionality; fixed in oldloader - Fix: TTD AI internals are still a puzzle and the AI in state 'SellVehicle' doesn't have a valid vehicle, so change the state to something harmless. Both fixed make sure that Megarail TTD scenario works --- oldloader.c | 21 +++++++++++++++------ 1 file changed, 15 insertions(+), 6 deletions(-) (limited to 'oldloader.c') diff --git a/oldloader.c b/oldloader.c index 3f85161df..052885c14 100644 --- a/oldloader.c +++ b/oldloader.c @@ -1069,6 +1069,12 @@ static bool LoadOldPlayer(LoadgameState *ls, int num) if (p->location_of_house == 0xFFFF) p->location_of_house = 0; + /* State 20 for AI players is sell vehicle.
