From a7b2ec60b3a1822ebf2ea4ee1ea136137cc68012 Mon Sep 17 00:00:00 2001 From: celestar Date: Fri, 21 Apr 2006 17:15:05 +0000 Subject: [PATCH] (svn r4501) -Fix: (FS#129) When, in a train that head multiple engines in front, the _first_ of those engines is sold, all the orders are copied to the second engine (to ensure "seamless" operation). However, during this operation, it was forgotten to update the prev_shared and next_shared pointers of the new head engine AND the next_shared and prev_shared of the share partners. --- train_cmd.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/train_cmd.c b/train_cmd.c index d3c1140af2..710738872b 100644 --- a/train_cmd.c +++ b/train_cmd.c @@ -1317,6 +1317,16 @@ int32 CmdSellRailWagon(TileIndex tile, uint32 flags, uint32 p1, uint32 p2) new_f->current_order = first->current_order; new_f->cur_order_index = first->cur_order_index; new_f->orders = first->orders; + if (first->prev_shared != NULL) { + first->prev_shared->next_shared = new_f; + new_f->prev_shared = first->prev_shared; + } + + if (first->next_shared != NULL) { + first->next_shared->prev_shared = new_f; + new_f->next_shared = first->next_shared; + } + new_f->num_orders = first->num_orders; first->orders = NULL; // XXX - to not to delete the orders */ if (IsLocalPlayer()) ShowTrainViewWindow(new_f);
