Simple answer is no.
The drift scoreboard is only an add-on for lapper.
Feel free to make your own, but you have to use the built in player functions within lapper - if you look in the lapper directory, you will find a file called playerVars.txt - this lists all the player variables that you can output. The one used in lapper is AngleVelocity.
Thing is, lapper, for us users, is a very simplified coding language made up by someone (Gai-Luron) to interface with LFS through the InSim protocol. All the hard work has been done for us, and basically converts lapper language into the proper InSim commands. Its not a coding language like C++, where you can make up your own functions and get do the math to work out vectors, etc.
In my opinion, if anyone has a non lapper drift insim, then they won't give to anyone else. Why should they? They've likely spent a lot of time and effort coding it (I'm talking weeks/months; not a few hours) and it might be the 'selling' point for people to use their server instead of the other 200-300 other servers available. Giving the code to you and others just means less people going on their server.
To be honest, if there were no drift scoreboards available anywhere, and I was making it now for first time, I wouldn't make it public.
The moral of this story?
Unless you're going to offer someone thousands of Euro's for what you want (based on hundreds of hours efforts at a decent [European] rate of pay), then get used to using the lapper drift scoreboard script. It's free, it works, and is consistant for everyone that joins your server.
As a demo user - someone who hasn't bought a license (I don't care if you say you don't have the money because running a server costs money) anything you can get for free is a bonus.
And if you look at the whole LFS forum, especially the Programmer section, you'll see that the lapper section is the ONLY section where you get free code. And also help when it goes wrong, or you're trying to do something.
Also. You've helped me come to a decision about something.
As a demo user, you (and other demo users) are making absolutely no commitment to LFS - buying a license is what I would call making a commitment - so I'm going to stop giving lapper help and advice to demo users.
For all I know (although suspect is true), demo users running lapper are probably using it on cracked servers. I'm not willing to help anyone who's not willing to help pay for LFS.
You have free game content along with free InSim software. Like every other game in the world, on whatever platform, if you want more, then you will have to pay for it. In this case, that means buying a proper LFS license.
