Well the error shows there's a missing semicolon at the end of 595 of the locomotive class, but that's not an issue with the source on git.

https://github.com/EternalBlueFlame/Traincraft-5/blob/1.7/src/main/java/train/common/api/Locomotive.java#L595

I'm thinking it might either be an issue with your git, or maybe your OS localization, one thing you can try is copying that class manually, or downloading the entire project manually as a zip, then extracting it and doing all the setup stuff from there.

I , git checkout 8c1f0dc
and built from that with no problem . I think KennyPeachKing added some extra punctuation in the newest commits . I compiled from the Command Prompt . Your IDE which ever it is is smart enough to remove a extra bracket or semicolon . compiling from the command prompt , it is what it is and fails

The compiled mod from that commit crashes on world load

looks like the recent compile is not compatible with worlds created with a older traincraft version

well it's not my IDE, because it compiles from command line fine for me, so something is different here.....

as for that crash, it's because that specific passenger car doesn't check if there's a rider before setting their position, i'll fix that now.

this may take a few minutes actually, this crash exists in almost every passenger car in the mod....

I downloaded the zip and compiled from that . I got the same results and a fail to compile . Im almost certain there is extra punctuation in the latest commit

okay yeah i found the missing brackets while i was fixing the stock, my local copy wasn't actually up to date. my mistake.
fixing it now

Forgot to ping this issue in the latest commit, but changes are pushed and all the bugs should be fixed.

yes it compiles now , but it still crashes on world load

Still a problem opening an exiting map .

on a new map i see that the mod has new Hover locomotives like in back to the future . lol , I know you fix 1 bug and create another .
just to let you know

whoops, missed the cabooses when fixing the rider offsetting, i'll deal with that now.

as for the hovering trains, that probably just happened from data corruption during all the crashes.

the hovering trains , i spawned on a new map that i created just to test the newly compiled traincraft mod .
I was testing the cabooses and discovered that spawning trains on the track hovered above the track . I will delete the config files and make a new map to test on . I will let you know what happens

I re-tested on a new flat map floating steams and diesels . The trains will no longer start

Doesn't really matter, I'm pretty lax with this stuff.
i think the issue is for whatever reason the bogie doesn't understand the track and it derails the train a block above the track. i'll have to double over the pathfinding code to see what breaks where.
I've also got a few texture bugs and other stuff to fix while I'm in there....

Small update, the issue seems to be that the bogie doesn't spawn on server side (remember that MC is still client/server in singleplayer). so now it's a process of figuring out why it doesn't spawn...

Did you want me to open a new issue with placing trains on tracks they spawn 2 blocks above the track and although you can enter them and place fuel , the train will not start?

I see you committed some fixes , here is the crash log for this compile . Game crashes on world load

These are moving trains

Still crashing on existing worlds on world load .
Further testing , no crash on a new world in single player

Path finding for trains is broken , the front of the train will stay in the direction it is placed on the track .
can not link trains to any cars .

this is what i found so far

alright, i think it should all be good now...?

All fixed , thx , closed
