From 9b99b95955d72e49821fe235c0d6fc1e75dc64b2 Mon Sep 17 00:00:00 2001 From: Samu Date: Mon, 1 Oct 2018 16:01:28 +0100 Subject: Fix #6574: Remove go to hangar orders when rebuilding airport When replacing an airport with another, cancel current orders of type 'go to depot' from aircraft still heading to it if the rebuilt airport doesn't have a hangar (helicopter vs heliport), or if the airplane can't land on the rebuilt airport (airplane vs helistation). Removes 'go to hangar' orders from all aircraft when replacing an airport with hangar with another without hangar (heliport). --- src/aircraft_cmd.cpp | 12 ++++++++++++ src/order_backup.cpp | 7 +++++-- src/order_backup.h | 2 +- src/order_cmd.cpp | 11 +++++++---- src/order_func.h | 2 +- 5 files changed, 26 insertions(+), 8 deletions(-) diff --git a/src/aircraft_cmd.cpp b/src/aircraft_cmd.cpp index d6d99ae24..7c3566372 100644 --- a/src/aircraft_cmd.cpp +++ b/src/aircraft_cmd.cpp @@ -2103,7 +2103,19 @@ void UpdateAirplanesOnNewStation(const Station *st) FOR_ALL_AIRCRAFT(v) { if (!v->IsNormalAircraft() || v->targetairport != st->index) continue; assert(v->state == FLYING); + + Order *o = &v->current_order; + /* The aircraft is heading to a hangar, but the new station doesn't have one, + * or the aircraft can't land on the new station.
