Some bugs I have found in r12852

Some bugs I have found in r12852

Postby SilverNexus » 08 Jun 2013, 00:25

I was just going to list off a few bugs I encountered while playing the subversion repository of SuperTuxKart (running on Linux Mint 15):

1. Sometimes, a flat white square of varying opacity will appear during the celebration animation after a race. This usually occurs on Grand Prixs, but I have seen it in Single Races (in both cases tied to the story mode), but never appears during the frustration animation. It has no effect on the gameplay itself, but sometimes makes it hard to read the finishing times of contestants. I am running in 1024*768 windowed mode, with maximum graphics level. My video "card" is the internal GPU on the Biostar Hi-Fi A85W motherboard. I did install the proprietary AMD graphics driver for this GPU in Linux, as well. I have seen this square on both myself and Pidgin while playing as Konqi.

2. While nitro boosting or looking backwards, the kart refuses to turn left. If you turn the kart to the right, then quick switch to the left, the kart will continue to turn right; otherwise, it will go straight.

3. When drifting it is possible to stop moving by not holding the accelerator. When you do stop, the screeching tire noise continues, and the accumulated drift boost is maintained.

4. From the stopped drift, you can drift backwards by hitting the down arrow.

5. On the At the End of Time (I think that's what its called, correct me if I'm wrong) Grand Prix, the award ceremony states "You unlocked a new feature!" However, I did not unlock any tracks, modes, or Grand Prixs by beating the Grand Prix.

6. As far as I can tell, the "Around the Lighthouse" Story Mode challenge is nigh impossible to beat. Even taking a shortcut after the sand under the bridge to the lighthouse does not shave enough time off my laps to beat any difficulty level. Having beaten every other challenge (often handily) on expert difficulty, I can only conclude there's either another shortcut that is better than the one I found, or that there is no way to beat this challenge.

7. Despite having beaten all but one challenge on expert diffuculty, the door that prevents the player from reaching Nolok has not opened, despite me having more than enough points to challenge Nolok (220 when the race requires 180).

All in all, a great project. I remember the TuxKart era of this game, and appreciate how far it has come.

If there are any necessary screenshots, just ask. I have a bunch of screenshots of most of these bugs.

This is the first time something like that is reported, so unfortunately it is probably a bug in your graphics driver

This is very likely a physical limitation of your keyboard and not a STK bug, see http://supertuxkart.sourceforge.net/FAQ ... eyboard.21 for details

This is a little odd agreed, but relatively minor :D maybe we could cancel skidding when velocity is too low. A low-priority ticket could be created for that on our bug tracker

SilverNexus {l Wrote}:4. From the stopped drift, you can drift backwards by hitting the down arrow.


If #3 is solved then this is no longer possible so that should not be an issue in and of itself

Good catch! That's a leftover from previous versions. I created a ticket : https://sourceforge.net/apps/trac/super ... ticket/993

Since you appear to be playing latest SVN : the lighthouse track was recently redone and the challenge hasn't been updated yet, we will likely re-tweak the challenge before next release.

Yes, it is required to finish all challenges (on any difficulty, however). We could probably just remove the bubble that says 180, it's not useful, we now have a door there

I changed the challenge for lighthouse in revision 12854.
Expert should be beatable now. (I managed to. Try out and give feedback on the times. ;) )

For some reason, this doesn't surprise me. VMware complains about my video driver every time I start up a VM.

Yeah, its my lousy keybord, I had the same lack of response in a text editor.

You cannot even begin to skid until you reach a certain velocity, so maybe that piece of code could be used for determining whether to stop a skid as well. The minimum skid should be a little bit less than the minimum start skid velocity, in case some bumps or slopes are in a track and thus would otherwise cancel the drift should they share a minimum.
Auria {l Wrote}:If #3 is solved then this is no longer possible so that should not be an issue in and of itself

Sounds like it should just go as a minor note on the end of the stop drift, saying that the stop drift leads to it.
Auria {l Wrote}:Good catch! That's a leftover from previous versions. I created a ticket : https://sourceforge.net/apps/trac/super ... ticket/993

My guess is that it could apply to any Grand Prix, I just happened to not unlock anything on that Grand Prix specifically. Looking at the ticket, I see you came to the same conclusion.

I assumed as much. I didn't see anyone else mention it, so I thought I'd make sure it was a known issue.
Auria {l Wrote}:Yes, it is required to finish all challenges (on any difficulty, however). We could probably just remove the bubble that says 180, it's not useful, we now have a door there

I assumed as much. There was no indication that this was the case, so perhaps a notification should appear if you near the door without having beaten all the challenges.

Much better. I turned 2:07 on novice, 2:01 on intermediate, and 1:56 on expert. For respective groups each difficulty is targeted toward, these new times should suffice.

After some more testing, I think I made the challenges a bit too easy. Probably lowering them with 5 seconds is a good idea.
Any feedback?

I think I see your point. On intermediate and expert, I just kept getting pummeled with basketballs, and still beat the times.

Ok, I'll lower them with 5 seconds and ask for more feedback from other players. :)
(Personally I find every challenge of every track pretty easy.. so I'm not sure how hard we should make those.)

I'm in the same boat on that one. My 1:56 time didn't even win the race, and with the number of times I was hit by items it probably shouldn't be fast enough to beat the challenge on expert.

Lowered it to 1:50. (My best time from the 3 runs I just did was 1:39)
I think it's because of the speed boost skidding gives. The challenge times are probably from before skidding was added.
