BUG - Problems when no legal move Thu, 03 September 2009 05:03
I submitted this via the contact system, but I think the system may have truncated my submission. The e-mail I received in supply only showed part of the following message:

============

Two related problems with TTR online.

1) A group of us were playing a game with unusual self-imposed rules - trying to get the worst score possible instead of the more normal attempt for the best score. So we drew all the destination tickets and the color cards. We ended up in the unusual situation where it became a particular player's turn, there were no color cards or destination tickets to draw, and that player had no color cards to play a route. So the game hung on that player's turn. He/she could take no actions, and the game would not "pass" for them.

I would suggest that you might add a check to the TTR code, so that if there are no destination tickets or color cards left, and the player has no legal plays to make (either because they have no color cards or don't have enough color cards to claim any of the available routes), that the computer just skip that player's turn.

2) So, with the game hung up, we all left. Since then, the "Resume Now" button on my account (name: psteinx) has been lit up as if I could resume that game. Of course, it won't let me resume the game (it was days ago) and I've played many other TTR games (successfully) in the time since. I've even left a (more recent) game and returned using the Resume button, successfully. Something about the odd game described in item 1 above seems to have caused this little bit of interface weirdness for me. It doesn't seem to be a problem, but still...

EDIT : By the way, the situation described in #1 above was on the U.S. map, though perhaps the bug might have been an issue on other maps as well.

I am relatively new to the game, so I am going to ask a dumb question.

If all of the players have drawn all of the tickets and all of the color cards, how could they not be in a position to make a legal move? At that point, the only legal move would be to lay down a train, and I would think that you would want to lay down single trains to get the fewest points possible. At that point, there are more color cards to draw.

On a side note, I have noticed a few times where the computer game just kind of stops. At least on my version, which is a Mac, if you click the help button, and then OK, it will resume just fine.

It's the main problem of the variant "loser wins" that often at the end of the game, when all the tix are drawn, and also all the 1er, 2er, 3er, 4er routes are taken and no color cards are left to choose, the player that has to lay down the next track does not have the color cards or lokos he needs to fit an open 5er or 6er route...

Yes, I can see that. I was imagining that the point of the original poster that no trains had been played, but if most of the smaller routes are gone, it could be an issue.

Of course, I mostly play the Swiss board, so there are nothing but short routes Rolling Eyes

Can you really call it a bug when you play in a manner that is not contemplated by the rules?

While the probability of this happening in a standard game is vanishingly small, it can theoretically happen, and this is a valid program state. That means that yes, this is a bug.

Now, it is certainly an extremely minor bug, and may not currently warrant any allocation of resources to fixing it, but yes, it is a bug.

"vanishingly small" or practically not possible?

Quibble over the phrasing all you like, it is still a valid program state. When a program screws up in a certain state, that's a bug.
