Hey guys, I'm actually not REALLY writing a game, but instead I'm developing a car diagnostic monitoring system. I'm writing software that will allow you to interface with the car's ECM, and read the information real-time. It actually sounds a lot more fascinating than it is... there's nothig that hasn't already been done a million times. However, one thing that I am doing that isn't done that frequently is that I'll be incorporating a logging feature. Basically, all that I'll be doing differently is that I'll take all the car's sensor values (tach, voltage, O2 sensor, fuel mixture, etc...) and I'll simply dump it into a comma delimited file every 1/4 second. For those of you who are car guys, this will basically give you the ability to have a road-capable Dyno... (helps you diagnose problems with your car and determine whether or not the car is running lean or rich at specific RPMs). Anyway, that said... I do intend to create the program's GUI so that it also acts as a real-time monitoring system... so what I'd like to be able to do is have a graphical (analog) tachometer. I'm already on this list, so I figured I would ask here.... in case anyone is developing a racing game, I figured maybe someone has done this before and could give me some pointers. I'd prefer to not use a 3rd party component and instead write it myself. It would have to be capable of updating every 1/4 second. I can program in Delphi, VB, and some Visual C++, so if you have example code in any of those languages, I'd like to see it! Thanks!!!
