For anybody that's gets an error when loading a save due to Lua saying name is nil, I was able to work around by editing "entry.lua". It's likely caused by unground station the UI wizard is referencing being missing/deleted.

I've hotfixed the entry.lua script to at least let the game load. Long-term stability is unknown but you can at least close the borked wizard window and continue the game.

@mercedes600sl2003 Honestly I don't know...

thanks for your answer, do we know a mod that will cancel the pedestrians crossing the roads? or is any mod with streets without pedestrian crossings? thanks

@mercedes600sl2003 you need to cut pedestrians over the road, or make it longer than underpass

hi , is any way to use this mod to force the pedestrians to use them instead of walking over the streets? seems for me that are ignored so far

@enzojz: Thank you very much, awesome!

Hi, v1.8 is causing a crash on the former build 35732. Unfortunately I can't update TPF2 because of the missing CommonAPI2 for now. Any chance to get the working v1.7 anywhere?

when i try to connect this to an underground station, half the time, the station doesnt recognise that i placed an underpass. any help?

My savegame suddenly crashed while tryring to load it. (multiple times) As I already build some underpasses I can't just remove the mod and reload it so I hope you can fix that or tell me if I'm doing something wrong.

here are the details

This error is usually caused by modding. Some game resources contain incorrect data.

Thanks

underpass mod keeps crashing

Extra info: The error occurred just seconds before an auto-save was due to occur. The previous auto-save was successful.

Got the following error on a save that has underpasses enabled, but I haven't built any.
The error seemed to occur randomly when viewing a stations info panel.

@Enzojz I'm on windows

@m8tix Many said that, but I don't have such problem here so I don't know what to do...

Does this need an update? I think its causing my game to crash....

@ptamme1970 @DarkSwan2296 @redflaven are you on windows or mac?

Same issue here

If i place this with the Underground station my game always crashes. At the end of the Crash log it says this: Mod: ''Underpass" (*(some numbers), 1) (consider removing this mod and contacting the mod author)

What should i do?

It's possible, however I removed the undo mod but nothing actually changed at all.

@DarkSwan2296 @twisted-pixel Some mod conflict I think, maybe the undo mod?

Unfortunately I've got the same issue too: every time I load the game I have the underpass link UI visible and it's impossible to dismiss it. After some minutes of playing or at the first attempt of placing a new underpass, it makes the game crash without saving. It's a pity because it's a useful mod, but it made my map completely unplayable (I couldn't even delete them becase it crashes anyway). I'd really love how to solve this problem keeping the mod.

I think i might also be getting the undo bug. when i load into the game, the underpass link UI is visible and doesn't respond to dismissal, but as soon as i place an underpass or underground station the game crashes with internal error. curiously, i had no issues during the previous session, when i created the bug, despite playing for several more hours after last using underpass. I was thinking maybe a way to get around the issue is to dump upon game exit, or startup, all unlinked id#'s associated with underpass, and or deleting their unlinked stations.

@Babaji Hello, if you just want to have building entries for underground station, nothing need to modify on this mod, just do as underpass_entry.con and .module do, the underpass script will take them as entries. We can talk it in private messages

@Enzojz No problem, would it maybe be possible for you to make an invisible version with no meshes for this type of situation ? It would allow us to make functional buildings for underground stations. as well as other entries that we'd place on top of your invisible one.

Maybe consider doing the same with the underground stations to be able to snap an underground station asset. In the creation of our mods, we'd give the exact settings in our description so it snaps perfectly. It would make your underground mods more open to modders with more limited capacities in scripting and make them able to make more underground station mods because not gonna lie, that's what's missing in Transport Fever 2.

@Babaji Hello, no but you can use the mod as a requirement. If any modification is necessary, I would like to do it. I say no because there's background script so any copy of script would lead to conflicts.

In fact you can do as underground station do, from the perspective of coding, underground station is a plug-in of underpass.

Hello ! Do you give me permission to implement your mod into mine ? It's a train station building with an underground access.

@Nicolai Maximov Undo mod is not mine, I may check it later, but in principle, it should be the undo mod make the compatibility change.

When placing an underpass and removing it with your undo mod, the game crashes when placing another underpass, due to missing id of the one removed before

@trevor07210831 选择建好的入口在窗口里面有第二个按钮是进入修改模式的，然后仿照新建的时候的步骤把新的入口附加到要修改的入口上

不好意思, 想請教一下怎麼修改已建好的地下入口? 想在原本建好的地道再增加入口

@info You can post the stdout here, not necessary all but the last part (about 20-10 lines)

Hi Enzojz, love this mod, especially for construction of underground lines to reduce traffic jams. Unfortunately, now there occures a 'fatal error' when I want to build crossing stations and entries for them...the interface/ menue doesn't recognize each of the stations...and the game crushes. Could I send you a screenshot of the error report, because the report is very long. How can I send you the screenshot?

@SovietSeamstress Not supported. Ps: you have a special avatar, are you maoist?

Great mod! Is there any way to place a station building instead of plain stairs?

@Tearous 如果是两点间的最短路径的话，是会有的

我想问一下 如果只是造了一对出入口，没有地下车站什么的，真的会有居民当做人行通道来用吗

@DrScarlett Yes, they are under street constructions

Never mind - found them under street constructions.
My first return to TF in a while with the spring update - first game: Enjoyz mods only!

Hi Enjoyz, do the underpasses still work after the spring update? I cannot find them in the road construction menu...

@s.f.s.d If I remembered correctly there's an extra button under module configuration after you built it, with this you are able to enbale the finished group being extensible.

Hello. I'm sorry, but it is possible to somehow add a new entry to exist group of entries? I have 3 connected entries and I want to add new one. But I have no idea how to do that. Please, help. Thank you.

@kas.schmidt1611 that's a game "feature", I wished but I can't help over it..
