Nobody's actually made what you're looking for but I've pointed you in the direction of a tool that can do what you want, if you put some effort into it.
He's still wrong, the analog guages software has the possibility to do that style by using transparency.
I'd say that the guage he's talking abou tis approximately an 80 degree sweep. The biggest pain in the ass is probably going to be finding the center of the arc for rotation. Find that and you know how big to make your images for the guage. good luck getting the "needle" to change color, though it's possible you could make the "guage" itself change color.
that guage is the most useless piece of....what ever i've ever seen in a game. What does it guage?,Why is this nessesary?, this isn't need for speed, shifting actually plays a role here, when it takes more than one person to restart a 4 person race.
so being 14 years old makes you not understand anything? dont bother, learn the hard way of how to shift. you dont need help if the engine sounds like it is going to explode, its time to shift.
I have been testing for half an hour and here is the result so far, a meter that changes color (kmh meter) and a RPM meter with LEDs, I know it looks awful, but if you test it you could see the possibilities.
The zip file contains all files, just place (overwrite) in XRT folder. Back-up !
Just to add to this, I'm 14 years old to. However, I understand most things said on pretty much all threads, and I have a wide variety of mods to my name. Not only on LFS, may I add.
if your a demo user why would you want this the car park isent a great drag strip..... and i really hope lfs dosent turn into nfs, that would be the worst thing that could happen
