2.0.1 alpha / 2.5 beta discussion

[Rob]

Enhancedtunnels are fudged in a72. They seems count as track for the pathfinder, but trains can't actually enter the square. They simply bump into it, get stuck on the border of the tile, and yet, keep going. I'd expect them to turn around, but they don't, and the vehicle window shows them as going at full speed.

Huh?, could be the fix introduced by Josef to fix vehicles going stuck. Please send me a savegame before it happens. I haven't had that problem yet. Does it aswell happen with trams off?

I have exactly the same with my savegame, with or without trams on.

[eis_os]

Well the stack get screwed totally, it's a wonder that TTD works at all. Will try to create a fix today.

[Patchman]

The usual DOS crash on start up (alpha72):

Code: Select all

memory protection fault
CS:EIP = 00AFh:00000013h

using -!v-:

Code: Select all

TTDPatch: nd string #042E at 0022F12B, found 03/04 at 00175000
Ergebnis: [Fehler!]

OK, everyone who has these crashes in DOS when starting TTDPatch, please try the attached test version. Run it like this:

Code: Select all

ttdpatch > ttdpatch.log

and

Code: Select all

ttdpatch -!v- >> ttdpatch.log

and then please attach the resulting ttdpatch.log.

[edit]Uh, forgot the attachment... here it is.

According to the wiki and the linter, the following action-3 is valid, but it crashes the game if any but the first listed ID is selected in the construction window :

Code: Select all

419 * 17     03 04 08 0A 0B 0C 0D 0E 0F 10 11 01 FF EF 00 DF 00

... and these action-3's, which do the same thing, are no trouble at all :

Code: Select all

419 * 10     03 04 01 0A 01 FF EF 00 DF 00
420 * 10     03 04 01 0B 01 FF EF 00 DF 00

The action 3 looks fine, and I suspect it is but that something else randomly overwrites memory. The register that's supposed to hold a point to the action 3 data instead contains "aTAC".

If the problem is reproducible with only that file in newgrfw.cfg, please send me the grf file in question.

[WWTBAM]

i tried your test version and it crashed before starting with nothing in the comandline and my usual cfg. Im also going to post the cfg i didnt get to send you patchman.

I got a crash in A72 when dragging the mouse during a game saved from A71.
Details et.al. are in the attached zip.

EDIT: This appears to be the same issue as reported several times by others in the Problems Topic.

The zip in this post contains crash logs, cfg's, a save game and a .txt accurate problem description.

[Peter1x9]

I got the same crash as well. Seconds before the crash, I noticed that I still could not get my buses to go to the depots. Disabling trams and restarting my savegame worked just fine.
I'm currently running a new game with the latest alpha (and trams enabled) to see if the crash only happens with savegames from older alphas. It's currently running ok, but I haven't got to the point where road vehicles are introduced yet.

Hmmm ... I am still able to load the game and drag and scan within a limited area. It is only when I approach the center of the map that I get a crash. the trams grf is on but none have been built. Read the text in my zip file for details.

Do I understand you right, you switch trams in ur cfg Off? Ever1 else it helped!
EDIT: if it wont help! sry then to bother you!

[stevenh]

I broke the drawing of road bridges in a72!
If you happen to have a save game, it'll load fine, until you try to scroll to an area where there is road travelling under any type of bridge.

That sounds like it might be my issue.
If so, the bridge doesn't need to be on screen ... just on a line running N to S. I'll test it when I get home. There is a save game in my zip above if you want to see for yourself.

EDIT: Hotfix A3 fixed it!

[Villem]

I seem to have a problem in my MegaRail game where road depots randomly apperear on landscape next to roads, and when i remove the road, the depot disapperears, but if the road is added again, it reapperears. dynamiting the depot does nothing, query tool called it a railway track piece..,

I also have tram track graphics apperearing on roads when removing road/rail crossings, or rail bridges over roads, and the tram track grf wasn't even on

Also many other oddities, like base for a monorail track apperearing, game says its railway track, and i when i dynamite it it doesn't disapperear and the game still says theres a railway track there.
And when i try using railway track removal tool, i think the game crashed from what i remember.

This only started happening after loading the game, before that the game acted fine, but on loading the first bug depot appeared in a town in middle of nowhere.

The crash log for that day had this to say:

Megarail seems to have issues!

From what I can determine, the game was saved a loooooong time ago and the array that hold the tile data have left over bytes in them.
Now, these usually wouldn't cause a fuss, but since I am now using the spaces where the garbage exists, everything is showing up.

All of this should only occur if you have trams=on.
If you don't have the LATEST grf loaded (the 'ghosting depots' would indicate you don't have the latest) and trams=on then there is bound to be graphical issues.

I also have tram track graphics apperearing on roads when removing road/rail crossings, or rail bridges over roads, and the tram track grf wasn't even on...

Known bug, working on it. But again, this means you have trams=on without the GRF loaded?

Also many other oddities, like base for a monorail track apperearing, game says its railway track, and i when i dynamite it it doesn't disapperear and the game still says theres a railway track there.
And when i try using railway track removal tool, i think the game crashed from what i remember.

I can't reproduce this... but I have MegaRail running right now...

Well, I think you should really care about savegames saved without your switch. You should have a check while loading the game, and if your switch wasn't on at save-time, you should clear everything that might contain garbage.

For an example, you can look at how I did it for newhouses. (Look at clearhouseidsfromlandscape in newhouse.asm and how it's called from loadsave.asm. Also, look at landscape6init in l6array.asm, it shows how you should clean things from L6 and L7 if your switch wasn't on at save-time.)

But this is the Megarail scenario, so it doesn't have any L6 or L7 saved, right?

So far the assumption that the unused bits in L1..L5 are zero have been pretty good, I'm not sure why this is broken in Megarail.

Got rid of the ghost depots by turning trams off, but i still got this base for a monorail track that claims its a railway track piece, and i can dynamite over it even though its owned by a other company.

Since patch a73 I’ve had several crashes, for no apparent reason.
The problem is that it seems random. When I load a game there is no problem for about 30 minutes then it crashes. When I saved the game just before that and reload that game it will not crash at the exact moment it did before?

Attached several crashlogs from the past few days.
