Ultimate physics!!!!

[yorkshirelad81]

Hi everyone, I found this game a little over a week ago and cant believe how good it is!!! I have tried and downloaded both blades and ducfreaks physics and found them both to be an vast improvement but not perfect. Anyway I am currently at college doing a programming course and have decided to use this game as my next project to try and better understand the physics. I would love to help blade, ducfreak or anyone interested to try and advance this game to the max!!! as I have already purchased sbk 07 and it is trully horrible i dont think we are ever going to get close to this game anytime soon! Does anyone know any of the source code eg what the different variables mean in the tyre and bike files? Any help would be greatly appreciated.

Regards

Mark

hi, i'm really happy to see that there's someone that want to improve this game like me, daz, and few other. about physics, i work a lot on it about sbk01, the files that u have to take care are Bikes and Tyres(data folder, but i can send u them, if u need). understand parametres is really difficult. about Tyres, to find a possible interpretation, the only way that i fuond to understand something is change a parameter and test the bike to see changes. it's really difficult anyway, but not impossible. i still remember the "meaning" of some parameters, so i can help u a bit in this way, but they are diffcult to match together too.
about Bikes, there are some parameters that are standard, or there's no sense to change them. for example there's something about the position of part of bikes, or about robound of suspensions, and somthing else. then u can find parameters about maximum rpm, couple, mass, and a lot of other numbers that i have no idea what do they do.
some few days ago i've done a new physics for a champ that i'm organizing with an italian forum(simbike). i think that physics it's really good because it's not too difficult, but very realistic anyway. in the first one that i've done, i've focus on make a phbysics that was realistic and that force to do set up. but now i learn that a lot of players aren't able to do good settings.

anyway, my email is [e-mail](the same for MSN), please contact me if u need something. or ask there.

Hi guy's I'm not much of a physics guru nor do I have much programing knowledge but I do have a bit of a problem with SBK 2001. One thing in the game that has been bugging for some time is failed gear changes. I race with Manual Transmission ON and enjoy it enough to keep it on even though this problem continues.

I have been looking at the Replays and Telemetry and the first thing I noticed is when the rear wheel is off the ground the bike will not shift. This is very common when braking at Kyalami turn 11 section 5 on the guide through and turn 14 section 8 The Kink (very bumpy). I also noticed that if wheel spin is present when accelerating I will miss the shift point and have to let off the gas or bring the lean angle up a bit to stop wheel spin in order to grab the next gear. I have been up shifting early in an attempt to stop wheel spin or at least give me more throttle control but this is very slow.

Well their it is, I believe that the root of the problem is the speed variation of the front and rear wheels. Although I can’t confirm this because the Telemetry does not have a separate reading for the front and rear wheels. If you have any Ideas on how to fix this that would be great.

abraham i'm not agree with u. i think that the only not good about shifting is that u can always sellect N gear. that's really a bad thing but, about everything else i don't think that it's a problem.
change gear since spinning is not too easy in real driving too and anyway is often useful to change a gear before, if u see that with the slower one u spin too much.
about changing gears when rear isn't touching the track, i haven't notice this thing before, but never have problem about this thing.
just try to be more used with manual gears.

sorry Blade but I have to say that your reply did not help me any way shape or form. When racing I feel the game is not accurately representing realism in the manual gearbox setting.

I agree with your comment about being able to shift to N wily still moving. I have been vary angry when I find my self coming out of the last corner on last lap in N. I have also noticed that if you are costing down the track in first above 10 000 rpm then shift to N, rev the motor and try to shift back into 1st there is no drive from the motor as if you were still in N although 1st gear is displayed. The engine will continue to redline even thought I have unappiled the gas, only when I shift back to N do the rpm’s drop and I can go on my way. Rpm depends upon the bike you are riding, in this case Yamaha. This occurs in most bikes in the game at about 8 000 rpm.

Concerning not shifting on turn exit, I agree it is not an easy thing to do in real life and I would not change setting to try and alter this failed gear change on acceleration. Although I believe that in real life you can down shift at just about any time ecept full lean. In fact I have with no adverse effects. I use this action (engine braking) to try and step the rear wheel out into a slid on turn in, in an attempted to bring the front of the bike closer to the apex of the turn. This can only be achieved buy down shifting early because there is no rear brake as in Moto GP. On some corners when the rear wheel leaves the ground this in not at all possible. In the case of Kyalami turn 11 section 5 I have such a hard time down shifting that I’m only in 3rd by the time I am at the apex watching every one passing me, pressing the down shift button feverishly .

abraham - if you've got the rear in the air and are on the brakes, it's locked the wheel up which means you can't change gear. Just like real life That corner at Kyalami requires a short shift before, then a bunch of quick shifts down you get used to it! Using auto transmission gets around that problem but ... it's not like real life!
If you're spinning the rear, it's unlikely that you'll be able to shift in real life as well too ... as for neutral - hey that happens in real life too

In real life, you can 'speed shift' on a bike by nailing the throttle, then chopping the throttle then shifting then back on the gas hard, without using the clutch. All that happens in less than a second and you've got to time it right or know where the engine likes to shift. You can buy quick shifter that automatically kill the ignition for a short time when you push on the gear lever, to achieve the same effect but without moving your right hand.

Basically, the transmission won't shift if it's loaded ie. on the throttle, the rear locked etc ... so in that sense, it's realistic

PS. IRL I ride the bike that donated the engine for the SB8K TL1000R
