fog

[smace]

I am trying to learn the @fog command. I know the format ( in rw) is fog(start,stop,r,g,g), but what do start and stop mean? Does mean the fog begins here at 0 and goes until stop, or is it a measure of how thick the fog is? How do you turn fog off?

@Fog (Start, End, Red, Green and Blue)

First, I have not actually used this command (yet), but my interpretation is:
Start is the distance in meters from the beginning of the route where the fog actually takes effect.
End is the distance in meters from the beginning of the route where the fog no longer has an effect.

Outside the limits of Start and Stop is where the fog is "off".

Does that help?

Start: How many metres from the cab the fog starts
End: How many metres from the cab the fog ends

@fog (20,100,140,140,140)
This will give a greyish fog, The fog starts 20 metres ahead, and you can see 100 metres ahead.

The fog will continue until you stop it with a code like this:

@fog (0,0,0,0,0)
or
@fog (0,0)

Not totally shure about that; test it youre self ;-)

Sorry for my bad english

@fog (0,0,0,0,0) is indeed the stop command and the others seem to work also. Thank you.

Here's an example of code I used for lighting effects for sun shining into a tunnel exit. The fog appears very gradually and starts to disappear before the tunnel exit just enough for the sky to appear only slightly affected by the fog. Before the train enters the next tunnel, the fog is almost completely gone.

That is actually the effect I was looking to do.
I ghave your T1 for BVE. Did you ever create a Toronto route to run it on?

[Stooopid_person]

If you put the numbers, the end number is smaller than the start, it will create a kind of wall.
