torcs-devel Mailing List for TORCS - The Open Racing Car Simulator

Hi,

I would like to implement a speed camera in TORCS, this would consist
of two things:
- a model of a speed camera placed on the track
- a "flash" when passing this speed camera at a too high speed

The first would be easy to implement, but I have no idea how to
implement the second part.

First, I recognize three scenario's:
1) You will have to see two flashes from behind when you yourself are
driving too fast.
2) You will have to see flashes when other cars at close range ahead
are passing the speedcamera at a too high speed.
3) You will have to see flashes when other cars at close range behind
you are passing the speedcamera at a too high speed.

Therefore my questions:
- Would it be possible to render a "flash"?
    - Could this be done by placing a light source somewhere? (Would
cover all above scenario's.)
    - Could this be done by making the screen white for a short
period? (Would only cover scenario 1)

- Would it be possible to detect passing cars (and their speed)?
    - Passing the finish line nodoubtly is detected. Can this be
used? Also on other parts of the track?

- Could you give me pointers on where to look for coding these features?

Regards,
Thomas
