Live For Speed Drift Community Forum

Hi drifters.

Last week, i have been writing some new code to get a cooperative twin point system in LFS, based on LFSlapper. Please keep in mind, that this is not a battle point system but a cooperative one. The code is now quite functional, however i know there are some bugs left around.

The scoring is based upon those parameters (in decreasing order of weight in the magic formula) :

- angle synchronisation between the 2 cars : same drift angle at a given time awards more points
- speed synchronisation between the 2 cars : same speed, more points. (Thanx Glazer for this one)
- distance between the 2 cars : the more distance, the less points.

and of course :

- average drift angle of the twinmates at given time
- average speed of the twinmates at given time
- average drift time length of the twinmates at given time

When twin mode is handshaked by both twinmates, the first 3 parameters are displayed on top of the player screen when in twin mode under the form :
- distance
- angle difference in the twin ( best is 0)
- speed difference in the twin (best is 0)

So, the most important is to keep synchronous, then keep close, and then after u can think to get wider and faster and longer. The variation is exponential, not linear : try twin 50m away other car or just drift while twinmate goes straight, then the score can actually become negative because too far and/or angle amplitude too high.
As it is a twin the score is shared by both twinmates.
The method may need some more adjustment, but i first need more testing, more twin laps to be completed, to see precisely how it behave under what condition/skills
So here is the purpose on this topic : please join "Fat Oil Drifting Ground S2" or "Fat Oil Drifting Ground" (demo) with a twinmate and go for it and report some feedback, here or online when am there connected in server.
When u there, type "!twinhelp" to get help on how to initiate twin mode. If i am online i will help whenever needed but plz first read !twinhelp carefully, as there are some known problems with for example, non-alphabetic characters in name which require driver to change nickname clear of them or may wreck the scoring dispay at end of lap. I will try to fix that in the future, but is somewhat of a headache.

Now if you have some good idea to improve scoring efficiency, I would give it some brain bandwidth for sure.


Thanx and Have fun !



Oh, just one more thing, my servers, and i, are very touchy with noobophobia and all other kind of swear and insults when they are targeted to someone (even self targeted). There is a robot watching messages. Whenever it catches some bad minded word, it will ban for the day, if the robot doesnt catch and i see it, i will ban manually, no escape, resistance is useless. So if u think, this is stupid ruling, or just cant keep ur tongue clean, dont even connect to the servers, or u will end banned and upset.

Do you know that even in D1GP only 10% the judges decide about the points...?? There is a thingy in the car that shows the precise angle of drifting, speed in every turns and distance from the clipping points. I have seen one of these machines as "we" also started to use it in Hungary, in the beginning of 2009

Was there when Fat-Oil was testing it, had a butchers and it's pretty good and i hope this will encourage team battles.

Don't pay attention to Vendetta, it's nice to see someone trying to bring something new and interesting to the community and for that we can only show thanks, so thank you and keep up the good work 

can it support more than 2 players XD

Banned ? no, as this didnt happen on the server (but u will be watched carefully whenever u change ur mind and join the server). And nice if u are not upset, sign of hope.

Ok mates, now as I read u, I think there is some misunderstanding due to me not being clear enough.
This is not a battle point system, this is a cooperative twin point system.
I'll try to rename the thread to get this issue away.

Aren't you the one who's upset to ban him coz he'd pointed out your failure?

Bye bye unknown person.

something srange here

if this would have been done by one of the most known player it would have got better comments

yes gordon, new ones as me where when I started lfs. just drift.. no line no nothing is being learned. that is what makes point systems bad.

But mr fat oil, I like that you are thinking new. work something out that makes scores of line to and not just speed/angle.

As things change and some peeps had good idea and/or some other showed some interest. I post some more infos.
Among many tunings, i added apex marker scoring as proposed

There is a thingy in the car that shows the precise angle of drifting, speed in every turns and distance from the clipping points.

System is functional overrall but needs refining. I ll add wallride soon, and have better 'collision' check, and incorporate it in twin score system which has seen many improvements (username instead of touchy nicknames and many more).

Each corner u have some results and corner score. Global apex score is displayed at end of lap.
It is at the moment not related to 'normal' point system, it is kept aside of it.
Servers run BL1  or Aston Cadet Rev with some quick throwed markers at corners.
Aston server has Green Pointer Cones to indicate marker location (is quite approx atm, but quite accurate too)

Be welcome for a test ride.

@slider308
not available atm because no user friendly interface to position markers. Or available with current existing marker layouts i made.

@all
But whenever u want a comp with this scoring system, dont forget to keep it as a tool for judges, not as a holy totem. All the wrath puking seen here is from people scared because they see it as a holy totem. That's a major mistake and wrong route.
Anyway...

Things happened :
Scoring system has been updated to D1 spirit grade, from what i read here http://www.drifting.com/forums/drifting-technique-forum/4692-drifting-rules-and-judging.html#post63456
if u have better info, plz share

Now score depends on entry, apex, exit and average car attitude in the 20m zone of marker position.
A bonus multipler is available when best apex distance < 4m and average angle +25°.

From each angle, speed or distance recorded, a formula is applied to get a factor with logarithmic progression (the higher, the harder to increase).
Then all factors (angle speed distance) are multiply with the following weighting (still experimental) :
2 entries + 3 apex + 2 exit + 6 average
So most important is average attitude then apex then entry and exit.

in game u can type !showstats to have a display of scoring parameters. Display will only happen after a scored marker. Then u'll get for each entry, apex, exit, average, the scoring factors and raw data for speeds angles & distance

There's now a spin detector when car is inside 20m zone.

Soon, grass markers will be available. Drive in zone and some penalty will happen.
Twin scoring system is on hold and needs implementation on new D1 grade eval system.
May happen a battle system too, where the chaser eats leader's point with distance factor or something like that

Any feedback or advices, clean from any agression/fear, is appreciated.
