+--- Thread: Penetrating a barrier in Paul Richard track (/showthread.php?tid=1077)
Penetrating a barrier in Paul Richard track - chrpapas - 02-25-2009
At the first section of the Paul Richard track,instead of turning right(my car was an F1-02) in the first turn and without reducing speed i kept my course towards the stacks of tires.I crashed on the white stack of tires which is on the right side of the truck.At this point my car instead of bouncing back it penetrated the stack of the tires and passed behind them.After that i kept going straight until my car fell "in the sky" and started levitating.i I think should not happen so you 'd better check it out.If you face any difficulties reproducing this bug please inform me.

There's actually a little opening there on the left where you can get through, too. In general with these sorts of "track bugs" we don't bother fixing them because c'mon, you're supposed to stay on the track. :-)

I think these things really should be fixed, but at this stage it is too much work for the people converting tracks to go through and fix all the little problems with them, so we'll just have to live with them, until VDrift gets some original tracks of its own perhaps.

i agree. oh, does vdrift have any tracks of it's own yet?
and the problem the op mentioned isn't just with that track. at least for me, i can go through any wall as long as i'm going straight on and over 200 kph. development, or release version. although it seems harder in the development one

No. :-( Although the rouen track (which unfortunately isn't my favorite course) is public domain, so we could do whatever we want to that one.

VDrift only checks for collisions 50 times a second to keep performance up, so if the car is moving really fast you can get into a case where one frame it's in front of a wall and the next frame it's on the other side of the wall, and so VDrift doesn't notice that it's impossible to get from one side to the other without crashing through the wall. There are some ways to fix this without checking for collisions more times a second; bullet has a "continuous collision" library, and also I could emulate that behavior by stretching the collision box based on how fast the car is moving. Can you point to a car/track combination where this happens easily (helps with testing any solutions)?

i find the picture below is easiest to replicate. kind of good though, cutting through that wall in monaco 88 makes half of the course a straight!

these are the easiest two. i've done it elsewhere, but it's hard enough that it's unlikely to happen to the average person.
