Details

This patch improves breakdowns. It features different types and severities of breakdowns, multiengine support and load-dependant breakdown chance. Currently it is train-only. For more information see the forum post: http://www.tt-forums.net/viewtopic.php?f=33&t=39518

Patch is against r 14286

I notice a problem when you have, for example, 10 engines, the train breaks down 10 times as much, and every broken down engine is reported as if the whole train is broken. Also the emergency stops and mechanical failures happen 10 times as much.

Attached is the newest version of this patch

@Yorick
You have a valid point here I think. Originally my intention was that the breakdowns which affect multiengine trains less (low power) would balance the increase in emergency stops and mechanical failures. I have done some quick testing, and it seems trains with many engines are indeed stopping too much because of breakdowns. I think I will therefore change the behaviour of emergency stops, so they happen only to the front engine. This should alleviate the problem somewhat. I'm not sure though, as I need to do some more playtesting first.

The attached diff disables emergency stops for all train engines except the first one. This should significantly reduce the problem of multiengine trains stopping too often. It also fixes a bug; the reliability of non-front engines now properly decreases when improved breakdowns is off.

Damn, forgot to attach the file. This is beginning to look like an awfully long list of replies-to-self ;-)

Hi,

Attached is an updated version of this patch. Based in r14542 it includes some minor fixes:
- hack languages files: append " - {STRING1}" to STR_885C_BROKEN_DOWN. Clean fix should add a new entry for all type of broken states.
- add a 'default:' clause to the switch in the initialisation routine in AfterLoadGame().
- add a cast to uint64 when performing v->breakdown_chance in train_cmd.cpp.
- in vehicle.cpp a reduced breakdown chance is defined for multiheaded trains but isn't used. Use it to check vehicle breakdown.

Thanks for your update, especially the fix in vehicle.cpp which really affected functionality.
I implemented your changes and some other fixes in version 2.4, although I kept the language files in a separate patch, see the forum thread.

Updated patch to r15954. The only change made come from r15308 regarding km-ish/h -> mph conversions for 'low speed' breakdowns.
Fixed languages files are in the second patch.

EDIT: there is a typo in the patches names: s/19504/15954/
